针对东濮凹陷浅层天然气层气测录井显示好、其它录井方法难以发现、电测资料难以判别等问题,该文在综合测试、气测等资料确定产层类型的基础上,主要利用计算机技术建立了气测解释浅层气层的多个图版和解释标准,提出了利用烃组成形态图版、烃含量区间图版识别浅层气层的方法。应用该方法对东濮凹陷浅层气解释结论与测试资料进行对比验证,结果表明利用气测资料识别浅层气效果好、解释符合率高,为浅层气层的识别和评价提供了可靠依据,促进了浅层天然气勘探开发的进程。
In view of the well logging data of shallow natural gas in the Dongpu sag and other well logging methods, it is difficult to identify the electrical data and other problems. Based on the comprehensive testing and gas measurements, Computer technology to establish a gas interpretation of shallow gas layers of multiple plates and interpretation standards, put forward the use of hydrocarbon composition plate, hydrocarbon content interval plate recognition shallow gas layer method. This method is used to verify the conclusion and test data of shallow gas in Dongpu Sag. The results show that the gas detection data can be used to identify the shallow gas well and explain the high coincidence rate, which provides a reliable basis for the identification and evaluation of shallow gas reservoirs , Promoted the process of shallow gas exploration and development.
