The results of demulsification of oil from the Zhanaozen field have been studied. As demulsifiers, nonionic surfactants of block copolymers of ethylene oxide and propylene oxide of various structure Basorol P123 and Disolvan were selected. At a temperature of 60°C, the degree of dehydration in the presence of Disolvan reached 94.2% after 60 minutes of thermostating, in the case of Basorol P123 – 54.3% after 100 minutes. The opportunity of microwave exposure using has been shown. Depending on the operating mode the increasing of temperature of the oil leads to the maximum dehydration of the oil emulsion. Increasing the microwave exposure power to 700 W showed greater efficiency for breaking down stable water-in-oil emulsions. Using the microwave exposure to the crude oil emulsion showed that the degree of dewatering in the presence of Disolvan reaches 100% after 28 seconds.

The results of the selection of mineral filler in the development of the composition of the outer layer based on low-density polyethylene (LDPE), vegetable and mineral fillers and technical gossypol (TG) are presented. It is shown that the stability of the obtained composites is the result of increasing the degree of cross linking of the stabilized LDPE in the presence of TG. The structure of gossypol molecules and its derivatives, such as multifunctional compounds, suggests that they are not only traps for radicals formed as a result of thermal and photo oxidative destruction of LDPE, but also lead to change of the supramolecular structure of the composite due to formation of bridging bonds between various macroradicals. This fact has a significant impact on the basic physical, chemical and mechanical properties of the material, which is confirmed by the study to determine the degree of crosslinking of polymer composites. Inorganic reinforcing fillers are usually stiffer than the matrix and deform less, which leads to an overall decrease in matrix deformation, especially near the particle due to the presence of the particle/matrix boundary. In order to establish the cause of the ductile-brittle transition, functional relationships were determined to describe changes in the upper yield strength, neck extension stress and tensile strength of composites with increasing taurite concentration.
The developed composition of the composite coating in mass %: vegetable filler-guzapaya-25; mineral filler-taurite (shale) - 10; savilen-5; technical gossypol-3; LDPE-50-55, fully meets the standard requirements 1390-003-11928001-01 “Steel pipes with external anti-corrosion coating based on extruded polyethylene”.

Drilling in the western part of the Karachaganak field (operator - Karachaganak Petroleum Operating b.v., KPO) presented such additional difficulties to the project as drilling horizontal wells with a low range of permissible changes in the density of the mud, catastrophic mud loss and high fracturing of the rocks. From the experience of drilling neighboring vertical wells in the Soviet era in this area, it became clear that the mud loss cannot be eliminated by conventional methods, such as pumping LCM or cementing.
Uncontrolled loss of drilling fluid prompted the use of adaptive drilling methods for further development of the field. The application of the pressure-controlled drilling method, in particular CHCD method, is not new at the Karachaganak field. “Drilling without returns” was successfully introduced, but a rotating preventer (rotating control device - RCD) was used for drilling without monitoring the well trajectory. It was imperative for the Operator to drill a horizontal well to increase the interval of the reservoir, while ensuring a possible increase in flow rate.
It was important for the company providing the directional drilling services to make sure that the technologies used would be applicable in a CHCD environment. Particular attention and approach are necessary for well planning using a rotary steerable system (Rotary Steerable System - RSS), telemetry and logging tools, the functionality of which in drilling conditions without returning the drilling fluid is associated with difficulties in transmitting telemetry data, controllability, subsequent maintenance of downhole equipment, and with the analysis of hydraulic calculations.
Close cooperation between the Operator and the service contractor has allowed to increase the efficiency of drilling operations and make significant changes to the design of the bottom hole assembly (BHA) and selection of the optimum bit. Using a special software platform, a team of engineers was able to simulate the possible behavior of the bit, underreamer, and BHA as a whole when drilling hard formation.
To prevent fatigue stress of BHA elements, at the planning stage special attention was also given to analysis of bending stresses of BHA at the expected dog leg severity of 4-8 ° / 30 m. The world’s first enlargement of the wellbore from 6 to 8 inches in the build up section under conditions of CHCD was successfully accomplished thanks to best practices and technologies.

In Kazakhstan, manganese is one of the most widely used alloying elements of steel, increasing its hardenability, hardness, tensile strength and yield strength. Manganese in ferromanganese and silicomanganese is a deoxidizer and alloying agent for steel and alloys. The development of ferroalloy production requires an increase in output up to 100 thousand tons per year to meet the needs of metallurgical plants within the state and beyond. Moreover, the main goal is to obtain manganese sinter for further redistribution, allowing to obtain better ferroalloys, including metallic manganese. Methods of chemical and physico-chemical analysis establish the characteristics and composition of manganese-containing raw materials and oil tar rocks. Derivatogram of manganese ore and a mixture for agglomeration using oil bituminous rock is characterized by two noticeable effects. The first exoeffect in the range of 500–520K is characteristic of the process of dehydration of manganese hydrates. The endoeffect in the region of 950-1010K indicates a significant absorption of heat during the decarbonization of manganese carbonates, as well as calcium carbonate compounds characteristic of the mineral part of the ore. Derivatives of a mixture of manganese ore with coke with a coke to oil bituminous rock ratio of 1:1, 1:2 are characterized by a two-stage exoeffect in the range of 280-320 and 480-520K, indicating the removal of crystalline hydrate in the first case of oil bituminous rock compounds.
Using the Astra software package, thermodynamic modeling of 2MnO₂ -C₂H₂-3O₂; 3Mn₂O₃-C₂H₆-3O2; Mn₃O₄-C₂H6-3O₂ systems was carried out, which is typical for the working compositions of agglomeration of manganese-containing raw materials in the presence of oil bituminous rocks.

Emulsions of vegetable oil/water were obtained and the effect of individual and composite surfactants on their stability was studied. Anionic sodium oleate C12H33СОONa and nonionic Tween-80 were used as surfactants. To predict the stabilizing properties of surfactants relative to the resulting emulsions, the surface tension of aqueous solutions of individual surfactants and their compositions was measured. The surface tension isotherms of the studied aqueous solutions of sodium oleate, Tween-80 and their compositions showed that the surface activity of composite surfactants is higher than that of the individual components. The “lifetime” of oil/water emulsions was determined at various phase ratios such as 9:1, 8:2, 7:3, 5:5, 4:6, 3:7, 2:8, 1:9, and it was revealed that the most stable emulsion is at a ratio of 6:4, which was used for further research. The effect of individual surfactants and their compositions on the stability of the selected emulsion was studied. It is shown that with the injection of individual surfactants, the life expectancy of emulsions increases by 45-50 minutes, and with the injection of the composition it increases up to 60-65 minutes. A good stabilizing effect on the emulsion of vegetable oil/water was shown by Tween-80 and the composition of Tween-80 and sodium oleate with a component ratio of 1:1.

The results of studies on obtaining difficult-mixed NPК-fertilizers. The research tasks were solved with the use of ammonium nitrate solution, the composition and properties of which are identical to the characteristics of the process solution, which passed the first stage of residue of the current production. The scientific and applied significance of the work lies in the fact that the research objectives are achieved in compliance with the regulatory technological regimes of the stages of primary evaporation, subsequent drying and granulation of ammonium nitrate production. The initial suspension mixture of the required quality and composition was prepared on the basis of a solution of ammonium nitrate produced by JSC «KazAzot», by adding to it the calculated masses of phosphorus flour produced by LLP «Temir Service», potassium salt-potassium chloride and additional mineral additives-ammonium and iron sulfates. As a result of evaporation, drying, granulation and cooling of the suspension mixture, the target products with the required ratio of nutrients in their composition were obtained. The obtained product samples were subjected to chemical and physico-chemical analyses. The influence of specific consumption of ammonium nitrate, phosphorous flour and potassium chloride on the ratio of nutrients by rototable planning-modeling to obtain an adequate regression equation was studied. It was found that the new NPK compositions are stabilized complex fertilizer compositions, with a total content of nitrogen, phosphorus pentoxide and potassium oxide from 28% to 30%. They also contain sulfur, calcium, magnesium, iron, new products of valuable fertilizing significance. It was found out that the received new NPK compositions on the basic physical and chemical indicators and consumer properties meet the modern normative requirements to fertilizing production. The practical implementation of the results of the work will simplify the traditional technology of production of ammonium nitrate, translate it into the production of difficult-mixed complex fertilizers with improved agrochemical and consumer properties.

It is no secret that animal husbandry is one of the most important sectors of the economy, providing the population with valuable and high-calorie food (milk, meat, eggs, etc.). In addition, livestock enterprises produce raw materials for the manufacture of light industry products, including such types as shoes, clothing, fabric, furniture and other items necessary for each person. Do not forget that agriculture produces organic fertilizers for the crop industry. Therefore, increasing the volume of livestock products is an important goal and task for the agriculture of any state while minimizing capital investments and unit costs.
In modern conditions, the main factor of productivity growth is the introduction of automation, mechanization, energy-saving and other intensive innovative technologies in animal husbandry.
Since animal husbandry-agriculture has a lot of labor, there is a need to use modern achievements of science and technology in the field of automation and mechanization of production processes in animal husbandry. This direction is obvious and priority for the purpose of increase of efficiency of the enterprises of a livestock complex.
Automation of separate processes, and then complex automation of all productions with application of the automated control systems (ACS), is one of the main directions of scientific and technical progress in the field of agriculture.
This article discusses the review of automated farm management systems and the development of software and hardware models. This software is used in Arduino microcontrollers to integrate all modules into a single automated system. In addition, it is designed to control the supply of feed on the farm, which in turn reduces the human impact on the workflow. The control equipment of the enterprise will be run on the Arduino. Automation of livestock farms today is an urgent problem, as the products presented by foreign firms, is not low. Therefore, there is a huge need to manufacture a domestic analogue with an acceptable cost not only for large farms, but also for medium or small farms.

Issues of freezing soil, frost heaving are difficult complex processes. Quantifying soil deformations associated with frost heaving and thawing is a challenge for geotechnical engineers. Changes in temperature affect influence of physical and mechanical properties of soils. This paper presents the dependencies of foundation settling on load using Plaxis 2D. The results of the models of the stress-strain state of the base were compared in the winter and summer periods. Changes in the settlement of pile foundations in seasonally freezing soils are insignificant and do not affect the bearing capacity. The purpose of this work is to compare the results of the calculation of the vertical settlement of a pile foundation by the finite element method of Plaxis 2D. A numerical analysis was carried out using the Finite Element Method (FEM) in the geotechnical program Plaxis 2D, which shows of change settlement of buildings in the seasonally freezing soil. The design in the program corresponds to the real data of the object.

Any interaction of a USB device with a computer is carried out using a microcontroller and so that it can carry out actions, a control code is stored in its own service memory that the normal user does not have access to. Each USB device includes a controller chip that can be reprogrammed with a small physical and software impact. This is where the concept of “BadUSB vulnerability” arises. Since this threat works with software and hardware implementation of microcodes, the danger of the threat of BadUSB is high. Since all operating systems of the Windows, Linux, Macintosh family are subject to it, protection against this threat is complicated. And standard manipulations with the reinstallation of the operating system, which are a universal solution for most vulnerabilities, are not able to “cure” a computer infected with BadUSB media. In this paper, a description and analysis of the work of sketches when creating a device with a BadUSB vulnerability is given, and possible methods of protection are given.

Identified and analyzed factors, along with maintainability, determining the reliability of the technical system. The influence of maintainability on the reliability of a technical system is investigated. Low maintainability is one of the reasons that entering the units and sections of the machine require frequent stops to replace short-lived elements, adjust and eliminate failures. A technique for managing the reliability of technical systems by improving its maintainability has been developed. The existing methods for evaluating the maintainability of systems are analyzed and an improved technique for managing the reliability of technical systems by improving its maintainability using the graph theory is proposed. The indicator ε, called the perfection factor, is obtained and introduced.
In the process of using the technical system, the consumer suffers large losses due to failures. This is primarily the direct costs of eliminating the failure itself and losses from the downtime of the failed equipment. The reliability of the system in the general case is determined by the durability, reliability, maintainability and safety.
Often, to replace a wearing element, it is necessary to almost completely disassemble the system, disrupting the relationships of components and parts. Consequently, serious design flaws in technology cause a large expenditure of working time and material resources when used by consumers. The proposed methodology takes into account the technological sequence of dismantling work during overhaul, the use of approved technical standards for time for dismantling and assembling.
The results of early research by the authors show that the technological process of disassembling systems when disassembling into elements comprises 7 levels of accessibility, and the engine for parts - 4. The level of accessibility of system elements has a significant impact on maintainability indicators. Based on this, it is further proposed to interlink the reliability indicator of system elements with the level of their availability.

Graphene can be functionalized by various groups of atoms. In this paper, we will consider the most studied method of chemical functionalization - oxidation. Various graphene synthesis methods have been continuously improved over the years to provide safer and more effective alternatives. Although Hammers extraction of graphene is one of the oldest methods, it is nevertheless one of the most suitable methods for the formation of bulk graphene. Graphene can be obtained as reduced graphite oxide, sometimes also called graphene oxide. The efficiency of this oxidation process can be estimated by the carbon / oxygen ratio of the obtained graphene. In this paper, the synthesis and physicochemical analysis of GO and RGO are given. GO was obtained using the modified Hammers method, then the obtained GO was chemically reduced using hydrazine monohydrate. GO and RGO had different morphology, quality, functionalized groups. Infrared analysis showed the presence of abundant oxygen-containing functional groups in GO compared with RGO. The results of the analysis showed that GO was successfully oxidized from graphite, while RGO was effectively reduced from GO.

In this work the peculiarities of the some processes (ion scattering, sputtering and implantation at channeling conditions as well as nanoclusters deposition and thin film growth) accompanying the particle-solid surface interactions has been investigated by different computer simulation methods (binary collision approximation, molecular dynamics,embedded atom model potential, energy minimization method).The scattering and sputtering processes at 0.5-5 keVArand Ne ions grazing bombardment of Si(001), SiC(001), Cu3Au(001), Ni(100) and Cu(100) surfaces and their possible application for the surface diagnostics and modification have been studied by computer simulation in binary collision approximation. Ion implantation at normal as well as at glancing incidence is carried out by computer simulation in binary collision approximation. Profiles of the distribution of channeled ions at implantation have been calculated depending on crystal lattice type, kind of ions and their energy. It has been shown that the channeling of low-energy ions through thin single crystal metal films can be used to determine the sort and adsorption site of light atoms adsorbed on a clean rear surface. It is shown that for paraxial part of a beam the main contribution to the total energy losses comes from inelastic ones. It has been established that the energy losses of ions transmitted trough thin crystal and depth profile distributions depend on width of the channel and mass ratio of colliding atoms. The deposition of bi-metallic AgnCom nanoclusters on Ag(100) surface and thin film growth have been studied at the atomic scale by means of classical molecular dynamics simulation. It was shown that the embedded atom model potential may be used successfully for studying of AgnCom nanocluster deposition on Ag(100) surface at the slowing down energies (0.25 eV – 1.5 eV per/atom). The adsorption of fullerene C60 onto the surface and edges of defect-free graphene was studied by computer simulation within the framework of classical molecular dynamics. The computer model of a single defect-free C60 fullerene was built by the energy minimization method using the second-generation Brenner potential (REBO) and the cohesive energy of each carbon atom in the fullerene was determined. It was established that the fullerene is better adsorbed on the armchair edge of graphene and worst on the its “corner” atoms.

In order to select a parameterization scheme for microphysical processes and processes in the atmospheric boundary layer in the Central Asian region, the difference between the observed and simulated meteorological parameters was calculated for 4 separate climatic seasons for 2000-2016. Publicly available observational data is borrowed from the global archives of the Meteorological Office UK and the Near-Surface Hydrology Laboratory at Princeton University USA. The boundary and initial conditions for the regional climate model were set on the basis of the ERA-Interim reanalysis data set. The results of numerical experiments are presented in the form of maps of the mean annual seasonal variability of the surface temperature at the level of 2 m and precipitation for the Central Asia domain. Three combinations of microphysics and boundary layer schemes are considered: the Thompson one-phase microphysics scheme using 5 classes of hydrometeors in combination with two atmospheric boundary layer schemes (YSU and MYJ) and the WRF Single Moment scheme with 6 classes of hydrometeors combined with the YSU scheme. It was found that simulation data using parametrization schemes for the MYJ PBL boundary layer and Thompson microphysics are better than others in agreement with the data on precipitation and surface layer temperature.
