| 摘 要： | 断层封闭性可表现为侧向封闭性和垂向封闭性.针对这两方面利用断裂带泥质含量和断层面物质涂抹分析法对歧南西斜坡的8条断层在沙三段的封闭性进行了研究,并借助于平衡剖面对其中五条主要断层(F2、F3、F6、F7、F8)的封闭性进行了动态分析,进而得出该区的油气运移特征.结果表明:断层无论是在侧向还是在垂向上其封闭性在纵向上是变化的;断层对该区沙三段的油气运移起遮挡的作用;砂体为该区沙三段油气运移的主要通道.

| Abstract: | Fault sealing is divided into lateral sealing and vertical sealing.Based on this point,this paper discusses the fault sealing on the west slope of Qinan by means of determining the shale content of fault filling materials and analyzing the shale smear on fault surface.In order to know the fault sealing in geology history,the course of the main faults(F2,F3,F6,F7,F8) evolution history is revealed.The characters of fault sealing on west slope of Qinan sag are as follows:(1) The second tectonic activity has limited effect on lateral sealing of faults.(2) The faults prevent oil migrating in Es3 in west slope of Qinan sag.(3) Hydrocarbon migrates from the center of Qinan sag to the west slope through sands. |
