利用气测资料识别浅层气层

Identification of Shallow Gas with Gas Logging

针对东濮凹陷浅层天然气气测录井显示好、其它录井方法难以发现、电测资料难以判刑等问题，在综合测试、气测等资料确定产层类型的基础上，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，提出了焊组成形态图版、烃含量区间日版识别浅层气层的方法。濮浅2井的气测解释结论与测试资料的对比结果表明，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。

Aiming at the obvious displaying of shallow natural gas formation in Dongpu depression with gas logging, but difficult to be identified with electric logging or other methods, the typical curve graph and interpretation standards for shallow gas formation with gas logging are built up with computer techniques, providing the pattern graph of hydrocarbon composition. By comparison the interpretation result with logging data of the shallow Well Pu-2, the result shows the coincidence rate of interpretation is higher, providing the reliable evidence for identification and evaluation of shallow gas formation.
