CHARACTERISTICS OF FAULTS IN THE PU-WEI RING DEPRESSION AND ITS CONTRIBUTION TO MIGRATION AND ACCUMULATION OF OIL AND GAS

摘要: 濮卫环洼带地质构造复杂, 洼陷带的勘探程度还较低。在系统分析断裂特征及其活动性基础上, 探讨了断层在油气运聚中的作用。研究表明, 卫东-文东断裂系和濮城-陈营断裂系各自分别由5条主控断层构成, 控制着该区的构造格局和油气运聚。卫东、文东、濮城南、濮31等断层活动时间长, 与成藏时间匹配较好, 是油气从深层向浅层运移的重要通道。断层和连通砂体构成了断层型、断-砂组合型油气输导体系。断层型输导体系沟通了烃源岩和储集层, 增强了油气垂向运移能力, 断-砂组合型油气输导体系以侧向输导为主, 断层主要起阻挡油气或调节油气运移层系和方向的作用, 导致在主断层附近形成构造-地层油气藏, 远离主断层的边部形成岩性油气藏。Abstract: The Pu-Wei ring depression, with complex structures, has been poorly studied. Based on analysis on the faults, this paper deals with function of the faults in migration and accumulation of oil and gas. The research demonstrates that both the Pucheng-Chenying fault zone and the Weidong-Wendong fault zone consist of five master control faults, which control the structural formwork and migration and accumulation of oil and gas. The activity of such faults as Weidong, Wendong, Pucheng, Pu31 lasted a long period and match well with oil accumulation in age. The faults serve as a prominent way for oil migration from deep zone to superficial part. The faults and sand bodies of good connectivity, as the main migration pathway, together constitute the fault-type and fault-sand-type transforming system for oil and gas. The fault-type transforming system connects souce rock and reservoir and enhances the ability of vertical oil migration; and the fault-sand-type is chiefly helpful to lateral transforming. The faults block or regulate migration and its direction, leading to the formation of structural-stratigraphic hydrocarbon reservoir near the main faults and formation of lithologic hydrocarbon reservoir at the edge far away the main faults.
