摘　　要：本文利用高精度三维地震资料及构造解析原理,明确关键构造期TP12CX走滑断裂构造演化特征,以此划分断裂分段类型。结合钻井生产数据、断裂宽度等统计结果证实存在与之对应的油藏模式。TP12CX走滑断裂分段特征是由于断裂运动方式的转变,导致了断裂的排列方式和断裂性质不断变化。断裂与下伏烃源岩多期油气生成运聚相匹配,在垂向上构成有效的输导系统,不同断裂力学段与油气充注点对应性较好。断裂缝网结构及相匹配的油气充注调整系统共同决定了油藏的发育特征。此认识对主干以及次级走滑断裂带油气勘探开发具有重要意义。The structural evolution characteristics of TP12CX strike-slip fault in key tectonic period are defined by using high-precision 3D seismic data and tectonic evolution principle.According to the drilling production data and the statistical results of fracture width,it is confirmed that there is a corresponding reservoir model.The segment feature of TP12CX strike-slip fault is due to the change of the movement mode of the fault,which leads to the change of the arrangement mode and the property of the fault.The faults are matched with the underlying source rocks in multi-stage hydrocarbon generation,migration and accumulation,and form an effective transporting system in vertical direction.The fracture structure and the matching oil and gas filling system determine the reservoir development characteristics.The research results are significant for exploration and development in the main and secondary strike-slip fault zones.
