摘要: 在分析二叠盆地Wolfcamp统构造、沉积特征的基础上,通过烃源岩、储层等方面的系统研究,深入剖析了Wolfcamp统致密油成藏条件,探讨了致密油成藏主控因素。研究结果表明,Wolfcamp统具有致密油富集的优良地质条件,发育一套优质烃源岩,以硅质泥岩和钙质泥岩为主,并和储层呈现"下源上储、源储互层"的优良配置关系。致密油产层和产能分布主要受烃源岩、储层和源储配置控制。烃源岩特征为最核心的控制因素,它决定了资源丰度;储层特征和优良的源储配置关系决定了致密油主要产层、油气运移方式和排烃效率,是致密油富集的关键因素。

Abstract: We conducted a deep analysis of the Wolfcamp Series tight oil reservoir formation conditions and discuss the main controlling factors of tight oil reservoir formation based on the analysis of the structural and sedimentary characteristics and systematic research on hydrocarbon source rock and reservoirs in the Wolfcamp Series of the Permian Basin. The results show that the Wolfcamp Series has good geological conditions for tight oil enrichment:excellent hydrocarbon source rocks that consist mainly of siliceous and calcareous shale and excellent " bottom-generating, top-storing" source-reservoir configuration. The main factors controlling the tight oil production and distribution are the source rock and reservoir characteristics and the source-storage configuration. The hydrocarbon source rock characteristics are the primary controlling factor because they determine the abundance of resources; the reservoir characteristics and good source-storage configuration determine the tight oil production, migration method, and hydrocarbon removal efficienc, and are crucial for the tight oil accumulation.

Key words: Permian Basin, Wolfcamp Series, tight oil, reservoir formation characteristics, controlling factor
