永进油田中生界低阻油层特征分析

Analysis on the characteristics of Mesozoic low resistance oil layer of Yongjin Oilfield

准噶尔盆地永进油田中生界油层具有低电阻率特征,多数油层与临近水层相比较,电阻率增大不到2倍,影响了油层在测井资料上的判识。通过大量的岩心资料分析,认为泥质含量、岩石粒度、地层水矿化度、构造倾角是本区油层低电阻率的主要影响因素,并依此为基础研究了低阻油层的识别方法。

Yongjin Oilfield of junggar basin Mesozoic reservoirs with low resistivity characteristics, most of the oil layer compared with the adjacent water layer,increase resistivity less than 2times,affected or gas reservoir in well logging data.Through a lot of data of core analysis,think the shale content,rock grain size,formation water salinity,tectonic obliquity is the main influence factors of low resistivity oil layer,and on the basis of the research on the low resistance reservoir identification methods.
