Reservoir-forming characteristics of inner buried hills in Jizhong Depression, Bohai Bay Basin

摘要: 利用地震、钻井地质和测试资料,结合勘探实践,对渤海湾盆地冀中坳陷潜山内幕油气成藏特征进行了研究。结果表明,冀中坳陷潜山内幕油藏的形成主要受烃源岩、储盖组合及输导体系的控制;发育2种类型的潜山内幕成藏模式,即与不整合有关的潜山内幕成藏模式、与断层有关的潜山内幕成藏模式,形成了顺倾坡层状、顺倾坡块状、逆倾坡层状、残丘块状、断壁块状和断壁层状6种潜山内幕油藏类型;中央隆起带潜山深层内幕圈闭、东部斜坡带和西部断阶带内幕圈闭是冀中坳陷今后潜山内幕油藏勘探的有利方向和区带。Abstract: The reservoir-forming characteristics of inner buried hills in the Jizhong Depression of the Bohai Bay Basin were studied based on seismic, well drilling and logging data as well as exploration practice. The results show that source rocks, reservoir-cap rock association and hydrocarbon migration pathways together controlled the formation of inner buried hill reservoirs. Two reservoir-forming patterns (related to unconformity and fault, respectively) and six reservoir types (layers along slope, blocks along slope, layers against slope, blocks in residual hill, blocks along fault wall and layers along fault wall) generated in the study area. Explorations should be focused on the deep inner traps in the central uplift belt, and the inner traps of the eastern slope belt and the western fault-step belt.
