摘要

超压在全球沉积盆地分布广泛,超压对油气勘探具有重要的意义。超压形成机制主要分为3类:①与应力有关的生压作用;②地层孔隙流体体积增大引起的生压作用;③流体流动和浮力的增压作用。指出超压不仅能改善深部储层的储集性能,增加其上覆盖层的封盖能力,而且是油气运移聚集的重要动力,能够加快和促进油气幕式运聚成藏,但是,对超压的形成机制和意义还存在一些争议,诸如超压对有机质生烃的具体影响和幕式成藏的周期性等问题,尚待进一步深入研究。

Abstract

Overpressured sedimentary basins are widespread and have great significance on hydrocarbon exploration. There are there types of formation mechanisms of overpressure: ①the influence of stress, ②the increases of porose fluid volume, ③liquid flowage and buoyancy. Overpressure improves the porosity and permeability of reservoirs. And it strengthens the sealing for hydrocarbon. There are still many problems to resolve, such as the influence of overpressure on the generation of hydrocarbon and the circle of episodic fluid expulsion. Further researches are needed on these issues.
