裂缝是东濮凹陷古潜山储层的主要储集类型,微球、双侧向、声波、中子、密度、自然伽马能谱等常规测井曲线对研究东濮凹陷古潜山储层的储集性和含油性具有一定的有效性。利用深浅双侧向幅度的大小及差异和纵横波对裂缝的不同响应,可以确定裂缝的产状及发育程度;而微球、双侧向和中子测井对裂缝中流体性质具有一定的敏感性。

The fracture is the main reservoir type of buried hill reservoir in Dongpu Depression. The reservoir characteristics. and hydrocarbon potential properties of the reservoir in Dongpu Depression have been studied using normal log curve of dual laterolog , sonic , neutrometry. The occurrence of fracture and development degree can be decided by value and difference of LLD and LLS , and the fracture’s different respond of compressional and shear waves ,but dual laterolog and neutron log use more suitable for the fluid in the fracture and the sensitivity is high.
