| 摘 要： | 利用高精度的三维地震资料，结合油田地质资料对永8 块断层几何学、运动学和动力学进行了研究。结果表明，该
断块为一典型东西向展布的同向叠覆型断层调节带，西侧主断层（辛120 断层）与调节断层在剖面上呈阶梯状组合样式，
东侧主断层（永105 断层）与调节断层呈地垒状组合；辛120 断层活动性减弱时，其位移量传递给永105 断层和调节断层；
力学分析认为该断层调节带是在左旋张扭构造应力场作用下形成的。通过对永8 块油气分布、油气来源以及断裂活动性与
封闭性研究，建立了永8 断层调节带油气成藏模式：主成藏期东侧主断层作为油源断层沟通了烃源灶和储集层并输导油气；
调节断层停止活动时间早形成断块圈闭，成为遮挡断层。永8 块西侧是有利滚动勘探开发区。

| Abstract: | Based on the study of fault geometry,kinematics,and dynamics in Yong 8 fault block using 3-d high-resolution seismic data with oil field geological data,we discovered an east-west striking synthetic-overlapping fault accommodation zone.The western side of the major fault(Xin 120 Fault) with adjusting faults shows a step-style structural pattern,and the eastern side of the major fault(Yong 105 Fault) with adjusting faults shows a horst-style structural pattern.When Xin 120 fault activity becomes weak,Yong 105 Fault and adjusting faults accommodate the displacement.Stress field of Yong 8 accommodation zone is left-lateral,transextensional.Through the analysis of distribution and source of Yong 8 fault block,characteristics of fault activities,and fault sealing properties,we constructed the accumulation model of Yong 8 block fault.The eastern side of the major fault is oil source fault which connected the source and the reservoir,and migrated hydrocarbon during the main hydrocarbon accumulation period,and adjusting faults stopped activities in the earlier period,formed fault traps,and became barrier faults.Western part of Yong 8 fault block is the target region for progressive exploration and development. |
