断层对油气成藏影响作用综述

Summary of the Effects of Fault on Hydrocarbon Accumulation

断层对成藏的影响作用是断块油气田成藏特征研究的重点,也是目前含油气盆地寻找油气藏的重要研究内容.分别调研了国内外断层对沉积作用、沉降、沉积中心以及成藏条件的影响,探讨了断层对成藏研究中存在的问题和发展方向,从正反两方面介绍了断层的开启和封闭在成藏中起的作用.认为,油气从生成到最终聚集成藏,断层都起着非常重要的作用,甚至决定了某个地质时期油气藏的形成.

The effect of fault on hydrocarbon accumulation is the key point of the research on the reservoir forming characteristics of fault block oil and gas field, and it is also an important research content of exploring oil and gas reservoirs in the current oil and gas basin. In this paper, the effects of faults on sedimentation, sedimentation, deposition center and reservoir forming conditions are investigated respectively, the problems and development trend of the fault to the reservoir forming are discussed, and the role of the opening and closing of fault in the formation of reservoir are introduced from two aspects. Finally, it is concluded that the fault is playing a very important role from the production to the final accumulation of reservoir for oil and gas, even it determines the formation of oil and gas reservoirs in a geological period.
