Естественно ожидать, что в этих условиях характер притока флюидов к горизонтальным скважинам будет отличаться от такового в коллекторах, залегающих на небольших глубинах. В связи с этим назрела необходимость в развитии моделирования фильтрационных процессов в условиях разработки горизонтальными скважинами глубокозалегающих месторождений, сложенных трещиноватыми и деформируемыми коллекторами. Поэтому проведение исследований, направленных на создание методов определения производительности горизонтальных скважин, работающих в условиях деформируемых коллекторов, становится актуальной научно-практической задачей. Статья посвящена усовершенствованию методики и анализу гидродинамических исследований процессов фильтрации жидкостей в деформируемых однородных и однородно-анизотропных пластах при эксплуатации их горизонтальными и вертикальными скважинами. Крупнейшие месторождения Казахстана – Z, долгое время обеспечивающие необходимые уровни добычи нефти, вступают в завершающую стадию разработки. В последние годы число месторождений с трудно извлекаемыми остаточными запасами нефти в подгазовых зонах, низкопроницаемых коллекторах, а также в пластах с высоковязкими нефтями, осложненными наличием разломов, активных подошвенных вод резко увеличилось. Эффективная разработка таких объектов не может быть обеспечена традиционными технологиями эксплуатации скважин.</p><p>В настоящее время разработка нефтяных и газовых месторождений с помощью горизонтальных скважин является одним из самых приоритетных направлений научно-технического процесса в отрасли вовлечения в промышленное освоение трудноизвлекаемых запасов нефти и газа.</p></abstract><trans-abstract xml:lang="en"><p>In deep reservoirs, changes in pore pressure during field development often lead to a situation where the difference between overburden pressure and pore pressure reaches values sufficient to cause deformation of the rock skeleton. This results in a reduction in both the number and diameter of open pores, leading to significant changes in the storage capacity and filtration properties of reservoir rocks. Under such conditions, the nature of fluid inflow to horizontal wells is expected to differ significantly from that observed in reservoirs located at shallow depths. In this regard, there is a growing need to develop models of filtration processes for deep reservoirs composed of fractured and deformable formations developed by horizontal wells. Therefore, conducting research aimed at developing methods for determining the productivity of horizontal wells operating in deformable reservoirs has become an important scientific and practical task. This article is devoted to improving the methodology and analyzing hydrodynamic studies of fluid filtration processes in deformable homogeneous and homogeneous-anisotropic reservoirs during their exploitation by horizontal and vertical wells. One of the largest oil fields in Kazakhstan – field Z, which has long ensured the required levels of oil production, is entering the final stage of development. In recent years, the number of fields with hard-to-recover residual oil reserves in gas-cap zones, low-permeability reservoirs, as well as in formations containing highly viscous oils complicated by faults and active bottom waters has significantly increased. The effective development of such reservoirs cannot be ensured using conventional well operation technologies. Currently, the development of oil and gas fields using horizontal wells is one of the most promising directions of scientific and technological progress aimed at involving hard-to-recover oil and gas reserves in industrial production.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>месторождение</kwd><kwd>исследование</kwd><kwd>скважина</kwd><kwd>производительность</kwd><kwd>нефтяной пласт</kwd><kwd>математическая модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>field</kwd><kwd>research</kwd><kwd>well</kwd><kwd>productivity</kwd><kwd>oil reservoir</kwd><kwd>mathematical model</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Imansakipova, Z.B., Buktukov, N.S., Imansakipova, B.B.
