摘要(Abstract)：

从增压作用和减压作用相互关系的角度 ,探讨了超压释放的定义——超压趋向于静水压力降低的作用。根据超压释放的结果 ,超压释放可分为不完全释压和完全释压 ;依突破压力封闭的动力 ,超压释放可分为主动释压和被动释压。有两类不同成因的超压释放通道 ,分别是自拓通道和它拓通道。超压释放的主要机制有断裂活动、水力压裂、底辟作用、渗透性岩层输导作用、渗透作用、剥蚀作用和人为作用。超压释放提供了油气运移的现实动力 ,开拓了油气运移的通道 ,促进了生烃作用 ,有利于超压系统内的油气成藏 ,影响油气的分布。超压释放分析为探讨超压与油气的运聚提供了有效的方法。

关键词(KeyWords)： 超压释放;增压作用和减压作用;自拓通道和它拓通道;运移和聚集
