应用套管井地层电阻率测井监测剩余油分布

Application of cased-hole formation resistivity log in monitoring distribution of remaining oil

套管井地层电阻率测井仪是为了满足油田在套管井中测量和评价地层剩余油饱和度而研制的新型仪器。该文介绍了套管井地层电阻率测井原理、解释分析方法及其在老油田垦东6断块的应用,并分析了固井质量和地层水矿化度对测井结果的影响。

Cased hole formation resistivity ( CHFR) logging tool is a new-type instrument which is developed to measure and evaluate formation remaining oil saturation in casing hole of oilfields. Principle, interpretation method of CHFR logging and its application in Kendong 6 fault block are introduced, and the influence of well cementation quality and formation water salinity are analyzed in this article.
