邵伯油田戴南组油藏成藏分析研究

摘要

Shaobo oilfield is located in the south of Shaobo secondary sag in the deep of Gaoyou sag ,which is the steep slope zone of south transition in Shaobo secondary sag .And it was a favorable directional zone of hydrocarbon migration . It mainly developed Zhen -2 fault and its branch fault within the region .Dainan formation ( E2 d) mainly developed near-shore subaqueous fans , and formed structure -lithology combined action reservoirs .On the basis of present understanding for hydrocarbon accumulation of E 2 d,a systematic understanding has been formed in term of the research on oil source rock features,effective source rock distribution ,cover characteristics ,oil and gas channel system ,accumulation mode and con-trolling factors ,etc.%邵伯油田位于高邮凹陷深凹带邵伯次凹南侧，紧邻邵伯次凹，为邵伯次凹向南过渡的陡坡带，是油气运移的有利指向区。区域内主要发育真②断层及其分支断层，戴南组主要发育近岸水下扇沉积，形成构造-岩性复合作用油藏。在现有认识的基础上，围绕该区戴南组油藏，通过对生油岩特征、有效烃源岩分布、盖层特征、油气疏导体系、成藏模式及控藏因素等进行研究，形成该区戴南组油藏成藏的系统认识。
