摘要
通过对某油田随钻测井与电缆测井在深度和曲线数值两方面的比较,表明了在该油田随钻测井资料良好,能为油气解释和地层评价提供可靠的信息。在对多口井随钻测井解释分析的基础上,总结了该油田随钻测井解释中应注意的问题及难点,如识别低电阻率油层、同一个砂体出现不同油水界面、曲线间互不匹配的岩性响应、井没有中子密度曲线等等,并探讨了一些解决方法。
The comparison between logging while drilling(LWD) and wireline logging(WL) curves of a oilfield shows that: the depth,value of resistivity,and distribution range of density of the LWD measurements are rather close to that of WL,invasion effect in LWD is less than that in WL,so LWD can provide more credible information for oil-gas interpretation and formation evaluation.However,there are only 5 logs of natural gamma,resistivity,caliper,density and neutron,so low resistivity pay can not be identified with them.Causes providing different oil-water interfaces in sand bodies with WL and LWD should be analyzed.Antinomic logging results between WL and LWD,which might be caused by conditions of deviated and horizontal well,need to search their reasonable interpretation.
