鄂尔多斯盆地X区长七储层水敏性实验分析及评价

Water sensitivity analysis and evaluation on Chang-7 reservoir in X area,Ordos Basin

文章主要针对储层水敏性进行实验分析及评价。分析了研究区储层的潜在损害因素,并通过水敏性实验分析和评价,认为研究区水敏性较弱,伊蒙混层和绿泥石是造成水敏的主要因素。

This article focuses on the experimental analysis and evaluation on the water sensitivity of a reservoir.It concludes that there exists a weak water sensitivity in the study area through analyzing the potential damage factors of reservoir and water sensitivity experimental analysis and evaluation.The illite/smectite mixed-layer and chlorite are the main factors that lead to water sensitivity of the reservoir.
