本文选用低成熟烃源岩，采取人工热解生成油气及适当控制石油运移的方法，模拟了４ 个地史热演化阶段（低熟、成熟、高熟、过熟）中油气的生成演化过程。试验中把热解生成烃适当分成排出烃和滞留烃，分别对应于地质体中油气经初次运移进入储层的量和滞留于母岩并同母岩一同继续演化的量。从未熟到过成熟阶段将油气的生成分成４ 个连续演化阶段，运移分成３ 个集中阶段，即用多阶段生成、集中运移模拟地质体中油气边生边运的地质过程，得到了不同演化阶段不同运移效率下储层中可能的油气分布。
In this paper, low maturity hydrocarbon source rocks are selected to generate oil and gas by artificial pyrolysis and the oil migration is controlled properly. The formation and evolution of oil and gas in four geothermal thermal evolution stages (low maturity, ripening, ripening and overriding) are simulated . In the experiment, pyrolysis-generated hydrocarbons are properly divided into discharged hydrocarbons and retained hydrocarbons, which correspond to the amounts of oil and gas entering the reservoir through initial migration in the geological body and the amounts of staying in the parent rock and continuing to evolve along with the parent rock. From immature to over mature stage, the hydrocarbon generation is divided into four successive evolution stages, and the migration is divided into three stages, that is, the multi-stage generation and centralized migration are used to simulate the geological process of hydrocarbon migration along the margins of the geological body. Possible hydrocarbon distribution in reservoirs under different migration efficiencies in evolution stage.
