油气藏破坏机理分析

Mechanism analysis on destruction of oil and gas pools

油气藏破坏是一种普遍的自然现象 ,地质历史时期任何类型的油气聚集都是短暂的动态变化实体 ,均随着时间的推移 ,在某些地质因素的影响下遭到破坏 .对国内外被破坏油气藏的地质因素进行了分析 ,研究了油气藏破坏机理 ,将油气藏破坏机理划分为物理破坏、化学破坏、生物化学破坏和物理化学破坏 4种类型 11种亚类型 ,其中物理破坏是油气藏破坏的最主要原因 ,而物理破坏中的构造变动是绝大多数油气藏破坏的直接因素 。

Destruction of oil and gas pool is a universal and natural phenomenon, every oil and gas pool in geologic time is a short and variable unity, and is destroyed by some geologic factors with the passage of time. According to analysis of the geological factors destroying oil and gas pools, this paper discusses the destruction mechanism of oil and gas pools. There are 4 types (physical, chemical, biochemical and physical-chemical ), which are divided into 11 subtypes, physical destruction is the most primary factor, and tectonic event is the immediate cause in destroying most oil and gas pools in physical destruction, it is the prerequisite of the others acting.
