埕岛地区输导体系发育特征

Characteristics of migration pathway system in Chengdao area

  • 摘要: 埕岛地区广泛发育断裂、砂体和不整合面等多种类型输导层,构成复杂的立体网络通道。以断层为垂向运移通道的潜山或构造油气藏常在断裂带附近多层叠置;以不整合面作为侧向运移通道的地层油气藏常形成于距烃源岩较远的东部斜坡带;以高渗砂层为主要运移通道的岩性油气藏多分布在凹陷周围距烃源岩较近的层位。埕岛地区油气藏多是油气经过两种或三种输导层阶梯式运移而形成的,多个不整合面、断层及各层系储集砂体的空间配置对油气分布的控制方式很复杂,砂体、断层和不整合面组成的输导体系的末端和边缘往往是油气运移的重要指向区。

     

    Abstract: Chengdao area is abundant in multifarious migration pathways as fault,sand body and unconformable surface, which compose a solid migration pathway.With faults as vertical migration pathway,the burial hill or the structural hydrocarbon reservoirs superposes in different geologic ep- ochs near the fracture zone.With unconformable surfaces as the lateral migration pathway,the stratigraphic hydrocarbon reservoir forms in the northern slope zone far from source rocks.With the high-permeability strata as the leading pathway,the lithologic hydrocarbon reservoir distributes in strata around the sag and near source rocks.Most of the hy- drocarbon reservoirs in Chengdao area consist of two or three kinds of migration pathways.This spatial configuration re- suits in a complicated control mode to hydrocarbon distribu- tion.The end and the edge of the migration pathway compri- sing sand body,fault and unconformable surface are signifi- cant places of hydrocarbon accumulation.
