埋深大于3 500 m 的深层气现场录井重组分较高,气层性质与油层类似。以往以单一的某种资料判别深层气,存在一定的局限性和多解性。文中以试油资料为主要依据,综合地质、气测、地化、测井等资料,提取最能反映深层气特征的多项参数,利用计算机技术绘制出各区块的二维图版,开发了深层气综合自动解释评价软件系统。根据东濮凹陷深层气显示、分布特征及气藏性质不同,划分出东部(杜寨、桥口、白庙) 、中部(濮城) 、西部(孟居、刘庄) 3 个含气区块,分别建立了深层气识别标准。

Based on the oil production test data, combining with geology, gas logging, geochemical logging, well logging data etc. , and the parameters submitted which show the characters of deep gas were used to map 2D typical curve graph with the computer techniques. The quantitative identifing standard of deep gas are established, and the software of interpreting and evaluating deep gas is developed.
