Достоверные данные об относительной проницаемости низкопроницаемых нефтематеринских пород пластов имеют ключевое значение для оптимизации разработки и эксплуатации месторождений за счет повышения точности гидродинамических моделей. Основными трудностями при изучении подобных систем являются ограниченность экспериментальных данных, обусловленная недоступностью кернового материала, а также неприменимость стандартных лабораторных методик из-за ряда свойств изучаемых объектов, таких как низкая пористость и проницаемость, высокое содержание органического вещества, включая кероген.

Исследование влияния таких факторов, как сверхнизкое межфазное натяжение, адсорбция и диффузия, на транспорт флюидов в условиях моделируемого пласта является крайне важным. Однако на сегодняшний день механизмы адсорбции и диффузии углеводородных газов остаются недостаточно изученными в научной литературе.

Цель данного обзора — предоставить всесторонний анализ опубликованных работ по адсорбции и диффузии газа в низкопроницаемых нефтематеринских породах. В рамках данной работы, была проведена оценка влияния различных свойств пород на поведение флюидов в наномасштабных порах и выделены будущие направления для дальнейших исследований. Предложенный обзор способствует улучшению интеграции данных адсорбции и диффузии углеводородных газов в гидродинамических моделях, тем самым повышая точность оценки извлекаемых запасов и снижая экономические риски при разработке труднопостроенных месторождений.

Reliable data on the relative permeability of low-permeability organic-rich shale reservoirs are essential for optimizing the development and operation of these fields by enhancing hydrodynamic models. Key challenges and limitations in studying complex reservoir systems include limited experimental data due to a shortage of core samples and the inapplicability of conventional laboratory methods for characterizing gas flow due to properties of these reservoirs (low porosity and permeability, high amount of organic matter including kerogen).

Investigating the effects of ultra-low interfacial tension, sorption, and diffusion on fluid flow under simulated reservoir conditions is crucial. Despite the importance of these factors, mechanisms of sorption and diffusion of hydrocarbon gases in shale rocks are often overlooked in experimental and numerical research on recovery strategies.

This review aims to provide a comprehensive understanding of gas adsorption and diffusion related mechanisms in tight shale rocks. Main findings include assessment of how various rock properties affect fluid behavior in nanoscale pores and identify critical areas for experimental analysis. By generalizing the review results, this work also highlights emerging research trends and addresses limitations in integrating adsorption and diffusion data for recovery, improving the accuracy of recoverable reserve estimates and reducing economic risks in unconventional reservoir development.
