摘要: 目前全世界已发现超压盆地180多个,其中160多个为富含油气盆地。异常高压油气田约占全球油气田的30%左右。与正常压力环境相比,在相同条件下,异常高压烃源岩中有机质的成熟度和产气率明显偏低,而产油率明显较高。压力的增加延迟或抑制油气生成和有机质成熟。分析了异常高压系统中压力与有机质成熟度的关系,结合实例阐述了异常高压对油气形成的作用与影响。详细介绍了异常高压的类型、成因以及对未来油气勘探所起的指引作用。

Abstract: Over 180 super pressured basins in the world have been found today, of which more than 160 are rich in hydrocarbons. The oil-gas fields with abnormal high pressure account for about 30 percent of the total fields. Compared with the normal pressure condition, the abnormal high pressure source rock tends to having lower gas production rate and organic matter maturity, but higher oil production rate, in the same conditions. The incremental pressure may postpone and restrain the organic matter maturity and hydrocarbon generation. The relationship between the pressure and the maturity in the abnormal high pressure system is analyzed. The effect of the abnormal high pressure on the hydrocarbon generation is discussed with some cases. Also, the types, origins of abnormal high pressure as well as their guiding roles to future

Key words: abnormal pressure, origin, hydrocarbon generation, thermal maturity, thermal evolution hydrocarbon exploration are presented in detail.
