| 摘 要： | 通过对鄂尔多斯南部中国石化各探区的烃源岩分布、构造格局、砂体展布、成藏组合、断-缝疏导系统等分析研究,得出大面积岩性油藏形成的控制因素为广泛发育的烃源岩和储集砂体、平缓的构造格局、有效的断-缝疏导系统以及有利的成藏组合。结合中国石化在鄂尔多斯南部各区块的勘探程度对18个勘探区带提出战略展开、战略突破、战略准备三个层次的分类。

| Abstract: | Based on study analysis of source rock distribution,structure characteristics,sand bodies' distribution,hydrocarbon accumulation assemblages,fault-fracture systems,etc.,the main controlling factors of large area lithologic reservoir were obtained,namely,widely developed source rock and reservoir sand bodies,gently structural characteristics,valid fault-fracture systems and favorable hydrocarbon ac-cumulation assemblages.On the basis of the study results,in combination with the prospecting degree of various blocks,three classification levels-strategy development,strategy breakthrough and strategy preparation of 18 exploration blocks were put forward. |
