沉积盆地中流体压力在地质历史中是变化的,所以很难确定压力对油气生成、有机质成熟作用的影响。高压模拟实验是研究压力效应的常用方法,但不同研究者采用不同的实验方式所得出的结论也各有不同。一些地质实例的研究则表明,压力增加可能会抑制或延迟油气的生成和有机质成熟。介绍了有关压力效应的不同观点,并提出压力效应研究中应进一步开展的内容及其意义。

关键词: 压力, 油气生成, 有机质成熟, 高压模拟, 抑制, 延迟

It is difficult to confirm the pressure effect on oil and gas generation and organic matter maturation,because the fluid pressure in sedimentary basins changes during geological history.High pressure simulation experiment is a good method to study the pressure effect,but different researchers come to different conclusions by different experiment methods.The geological case studies show that increasing pressure can suppress or retard petroleum generation and organic matter maturation.Different viewpoints on pressure effect are introduced in this paper,and the future work should be developed in pressure effect study and its meaning are also put forword.

Key words: Pressure, Petroleum generation and organic matter maturation, High pressure simulation, Suppress, Retard
