【摘要】 从油藏描述入手 ,结合地质、地震与钻井资料 ,系统地分析了辽西低凸起油气成藏的主要控制因素。综述了辽西低凸起南段、中段、北段的构造演化史、沉积发育、油气运移史、油气富集层位和油气运移通道组合。将辽西低凸起东西向分为凸起主体 ,东侧斜坡带和西侧陡坡带 ,并分析了相应的圈闭类型及油藏。研究认为 ,其东侧斜坡带与反向断层相关的潜山 -披覆背斜、半背斜及鼻状 -岩性圈闭是今后油气勘探的重要目标更多还原

【Abstract】 Primary controlling factors of low arch oil?gas reservoir forming in Liaoxi are studied systematically starting with reservoir description combined with geologic, seismic and drilling data. The combination of structural evolution history, depositional development, oil?gas migration history, oil?gas enrichment horizon and oil?gas migration pathway of south, middle and north sector in the low arch of Liaoxi is summed up. The low arch in E?W direction is divided into arch host, eastern slope belt and western abrupt slope belt, and the corresponding trap types and oil reservoirs are analyzed. It is considered that buried hill?drape anticline, monoanticline and nose?lithologic trap related to antithetic fault at eastern slope belt will be the important target of oil?gas exploration in future.更多还原
