盐间非砂岩成像测井裂缝识别方法

Fracture identification methods for the imaging logging in insert salt layers nonsandstone

江汉油区盐间非砂岩具有各向异性和非均质性,仅仅利用常规测井系列难以满足地质评价的需要。通过近几年的研究,我们充分利用MAXIS-500,CLS-5700,Excell-2000i成像测井新技术,积极开展实验和理论研究,取得了一些新的更有效的盐间非砂岩裂缝储层评价的方法及技术。包含盐间非砂岩的裂缝识别方法和地应力分析两个方面。

The insert salt layers nonsandstone of Jianghan Oilfield has the characteristics of anisotropism and heterogeneity,thus general logging series cannot satisfy the needs of geologic evaluation. Through the research of recent years,we have made full use of imaging logging technologies,such as MAXIS-500,CLS-5700,Excell-2000i,and conducted experiments and theoretical research actively,and gained some new and more effective methods and technologies for the fractures evaluation of insert salt layers nonsandstone,which include the two aspects of fractures identification methods and terrestrial-stress analysis of insert salt layers nonsandstone.
