泌阳凹陷页岩油富集段资源评价及有利区预测

Resource evaluation and favorable area prediction on rich section of shale oil in Biyang Depression

页岩油资源开发能否取得成功主要取决于2个方面,一是页岩油的资源丰度,二是页岩油的可采性。文中通过建立页岩油富集段划分标准以及泥页岩有机非均质性的测井识别,对我国最早取得页岩油突破的泌阳凹陷进行了页岩油富集段划分,并对其资源潜力进行了评价,结合泥页岩无机非均质性测井识别与原油物性分析指出,泌阳凹陷页岩油勘探开发的有利区为东南部工区。

The success of the resources development of shale oil mainly depends on two aspects. One is the resources abundance of shale oil and the other is the recoverability of shale oil. In this paper, the rich section of shale oil in Biyang Depression, the earliest breakthrough of shale oil in China, was divided and its resource potential was evaluated by establishing the division standard for the rich section of shale oil and the logging recognition of shale organic heterogeneity. Then, the favorable area of exploration and development was predicted combining with the logging recognition of shale inorganic heterogeneity and the property analysis of crude oil. The southeast work areas in Biyang Depression should be the next favorable target area for shale oil exploration and development.
