摘要
构造、储层和烃源条件研究表明,东濮凹陷潜山主要为断裂控制的后成潜山,储层条件以下古生界峰峰组风化壳和上马家沟组相对较好,油气源为下第三系源岩和上古生界煤系地层,通过原油生标物对比发现。
Research on tectonic, reservoir and oil source bed indicates that most of the buried hills in the Dongpu depression are controlled by faults. Weathering crust of the Lower Paleozoic Fengfeng Formation and the Upper Majiagou Formation are better reservoirs. The Lower Tertiary rocks and the Upper Paleozoic coal-bearing strata are the oil-gas source beds. Biomarker correlation indicates that a part of oil or gas was originated from the Lower Tertiary.
