【摘要】 断层是油气运移的重要通道,同时断层圈闭也是油气圈闭的重要类型.对断层泥、断层非渗透性物质(沥青质、胶结物)、断层两盘的岩性和产状对接关系、断层面应力特征、断层活动性、断层"地震泵"的抽吸作用、断层面上油气运移路径、油气沿断层走向运移、油气从断层向储集层的运移等对断层输导、封闭性能的影响进行了研究分析,并指出其存在的问题:油气在断层走向上的运移机理;断层中砂泥岩裂缝的发育对油气输导、封闭性能的影响.更多还原

【Abstract】 The fault is the important passage of hydrocarbon migration and the fault closure also is the important type of oil trap.After analysis and study the fault clay,the impermeable matter of fault(the pitch, the cement matter),the faulted contact ground and the fault dip,the strain of the fault inlier plane,fault activity,the fault of"pump of earthquake",the pass of fault inlier plane,the migration of fault set strike,the migration from fault to stored land.As mentioned above,we proposed that the two problem are still need be reinforced study:the hydrocarbon migration mechanism follow the fault set strike;the rift of grit mudstone spatial distribution pattern of the cracks in sedimentation basin effect closing a function.更多还原
