摘要:  目前对于石油在张性断层系统中的运移问题,除了通过岩芯和野外露头研究外,更多的是通
过物理模拟来研究,而采用数值模拟方法来研究该问题则很少.基于前人在张性断层系统中石油运移过
程的物理模拟结果,采用多相流数值模拟软件丁OUGH2 ,建立了该张性断层系统中水汽y山三相流的二
维剖面数值模型.结果表明,TOUGH2软件可以用来模拟和分析石油在张性断层系统中的运移规律及
分布特征,与物理模拟相比,基于TOUUH2软件的数值模拟具有成木低廉、操作灵活等特点,适用于各
种复杂条件下水一气一油三相流的运移模拟.

Abstract:  In addition to litho-gcochemical investigation of rock outcrops and core samples by drilling, more physical
analog experiments were often used to analyze or simulate the migration of oil in the operrfracture fault systems,
while numerical simulation methods arc rarely applied to address these issues. In this study,the multiphase flow nu-
merical simulation software TOUGH2 is used to build a two-dimensional numerical model of a cross-sectional profile
for modeling two phase flow of water-oil in the operrfracture fault system, based on the results of the previous physi-
cal analog experiments of the migration of oil in the operrfracture fault system.The modeling results show the
TOUGH2 can be used to characterize the migration and distribution of oil in the operrfracture fault system. Moreo-
ver,compared with physical analog experiments, numerical simulation methods such as TOUGH2 are cost effective
and operatiorrflexible and can be applicable to modeling three-phase flow of watci-gas-oil under a variety of complex
conditions.
