摘要:
哈萨克斯坦K油田部分油层电阻率较低，测井解释为油水同层，但经试油验证为油层。为了提高测井解释符合率，采用电阻率与自然伽马交会图分析技术分析了该油田低阻油层成因，认为该油田高矿化度地层水及岩石孔隙中束缚水、毛细管水是形成低阻油层的原因，并总结了两类低阻油层识别方法。利用建立的低阻油层识别图版对该油田老井进行复查，并提供试油建议，3个潜力层试油均出油，说明该低阻油层识别方法切实可行。
There were some low resistivity reservoirs in K Oilfield of Kazakhstan, interpretation indicated that those were oil-water layers, but oil test indicated that those were oil layers. In order to im-prove the interpretation coincidence rate, resistivity and gamma logging cross plot were used to analyze the origin of low resistivity reservoirs of this field, and it was considered that the low resistivity reservoir was caused by the high salinity formation water and capillary water and bound water in the rock pore, the identification method for two types of low resistivity reservoirs was also summarized. Some old wells are checked with the established low resistivity reservoir identification chart board and testing recommendations are provided. Three potential oil layers are tested and all of them produce oil, which indicates that this identification method of low resistivity reservoir is feasible.
