源岩内岩性油气藏形成的模拟实验及机理分析

摘要

通过模拟实验，再现了源岩内岩性油气藏的形成过程，对油气运移的受力状态进行分析，探讨了油气聚集成藏的机理，实例说明，源岩内的砂体一般都含油气，这为寻找岩性油气藏创造了条件。%Accumulation process of lithologic reservoirs of oil and gas insource rocks is reappeared by physical modelling experiments. Analysing the forced state of oil and gas during the migration, this paper discussed the formation mechanism of oil and gas accumulation. Typical examples show that there always is oil and gas in the sandbody in source rocks. This offers conditions to explore lithologic reservoirs.
