渤海海域低电阻率油气层特征及其识别方法

CHARACHERTRISTICS AND IDENTIFYING METHOD OF LOW-RESISTIVITY RESERVOIRS IN BOHAI BAY

近儿年来,在渤海海域发现了大量的低电阻率油气层,经测试证实,许多低电阻率油气层具有较高的产能,因此对低电阻率油气层的识别将越来越重要.通过对渤海海域低电阻率油气层测井特征及成因分析,得出了一些适合于该地区的识别方法,在此基础上对部分老井的测井资料进行了复查研究.

In recent years, a lot of low resistivity reservoirs were found in Bohai Bay, and much of them had high productivity by testing. So it is more and more important for us to identify and evaluate the low resistivity reservoirs. According to analyses of logging featuresand genesis in these reservoirs, we have developed some identifying methods suitable for Bohai Bay. Using these methods, logging data of some old wells are checked and analysed.
