摘要
断裂调节带是构造变形区调节构造平衡的一类重要的地质构造。综合地质、地震等分析资料对高邮凹陷主要断裂系构造的分布特征及其各构造带的石油地质意义进行了研究。结果表明,高邮凹陷内存在真武-吴堡断层同向类叠置型、真②断层内同向类叠置型、吴①断层内同向类共线型、汉留-吴②断层间共轭反向类共线型4种断裂调节带类型。凹陷内同向类调节带易形成主水系通道,各种沉积扇体和鼻状圈闭发育,而且临近凹陷内生油中心,易于形成油气富集带,是油田的主要分布区;而共轭反向类调节带则位于凹陷内低幅凸起,其水系不发育,缺乏沉积砂体,远离生油中心,不利于成藏。
The fault accommodation zone is a significant geologic structure which regulates the kinematic equilibrium in tectonically deformed regions, so the geologic distribution characteristics of the main faults and siguificances of petroleum geology of various tectonic belts in Gaoyou depression were investigated on the basis of comprehensive analysis of geology and seismic. The results show that there are four big fault accommodation zones in Gaoyou depression, namely Zhenwu-Wubao fault synthetic-overlapping fault accommodation zone, Zhen ②inside fault synthetic-overlapping fault accommodation zone, Wu ① inside fault synthetic-collinear fault accommodation zone, and Hanliu-Wu ② fault antithetic-collinear fault accommodation zone. The synthetic fault accommodation zones are apt to form water systems. Various sedimentary fans and structural traps are developed, and are close to the oil-generating center,so they are places of main oilfields in Gaoyou depression. While antithetic fault accommodation zones, being uplifts of low amplitude, are not favorable to oil-gas pooling because of no devel- opment of water systems and the sand bodies, and long distance from oil-generating centers.
