针对浅气层的测井响应特征及老井测井资料较少、资料刻度不统一的情况 ,综合利用已有的普通电法测井、声波测井及中子伽马测井资料 ,提取了识别天然气层的声波时差相对比值、中子伽马归一化值及电阻率相对比值等特征参数。在此基础上 ,应用交会图技术和数理统计方法建立了有效快速直观显示浅气层的标准和方法 ,编制了相应的解释软件 ,对 2个地区近 2 0口井的资料进行了处理 ,解释结果与试油资料吻合较好。 Aiming at the characteristics of well logging response in shallow gas reservoirs and the lack of data from old wells and the inconsistency of data scales, the general electric logging, sonic logging and neutron gamma logging data have been used synthetically Identification of natural gas layer of the relative ratio of acoustic time-lapse, normalized value of neutron gamma and resistivity relative ratio and other characteristic parameters. Based on this, the criteria and methods of effective and rapid visualization of shallow gas layers are established by applying the cross-plot technique and mathematical statistics, and the corresponding interpretation software is compiled. The data of nearly 20 wells in two regions are processed and explained The results agree well with the test oil data.
