Высокомолекулярные смеси, такие как смолы и асфальтены в тяжелой нефти, определяют ее уникальные структурные свойства, проявляющиеся в характеристиках нелинейного просачивания. Пороговый градиент давления является критическим параметром при изучении недарсиевского течения. В данной статье представлен всесторонний обзор прогресса исследований погрешности градиента давления в коллекторах тяжелой нефти. В ней обобщены основные методы определения порогового градиента давления, включая лабораторные физические эксперименты, численное моделирование и интерпретацию результатов испытаний скважин, а также сравниваются преимущества и ограничения каждого подхода. Кроме того, в ней анализируются ключевые факторы влияния, такие как вязкость сырой нефти, проницаемость и водонасыщенность. Результаты показывают, что пороговый градиент давления, как правило, увеличивается с ростом вязкости сырой нефти, увеличивается с ростом водонасыщенности в низкопроницаемых кернах, но уменьшается с ростом проницаемости. В данном исследовании представлены систематические выводы относительно этих факторов влияния и методов измерения, направленные на минимизацию погрешностей измерений и предоставление теоретической основы для оптимизации процессов закачки и добычи в коллекторах тяжелой нефти.

Polymer flooding is one of the key technologies for enhancing oil recovery. Partially Hydrolyzed Polyacrylamide (HPAM) is widely used due to its excellent viscosity-increasing properties. However, the adsorption and retention behavior of HPAM in reservoir porous media presents a dual effect: on one hand, it improves sweep efficiency by increasing flow resistance; on the other hand, it leads to a loss in effective polymer concentration and viscosity, reducing displacement efficiency and increasing costs. Therefore, a systematic understanding and control of HPAM adsorption behavior are crucial for improving the effectiveness of polymer flooding. This work systematically reviews seven main measurement methods for HPAM adsorption quantity, comparing their applicable conditions and limitations. It summarizes the key factors influencing HPAM adsorption and retention behavior from three aspects: polymer properties, rock mineral characteristics, and reservoir environmental conditions. Furthermore, it outlines chemical anti-adsorption methods, represented by competitive adsorption and nanofilm protection, along with their mechanisms. Finally, future research directions are proposed, focusing on building adsorption prediction models, deepening the understanding of adsorption mechanisms under multi-field coupling conditions, and developing novel functional polymers with anti-adsorption capabilities.
