埋深大于 3 5 0 0m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。
In-situ deep well logging components with a buried depth greater than 3500 m have higher log-heavy components and similar gas layers. In the past a single kind of information to identify deep gas, there are some limitations and multiple solutions. In this paper, the test oil data is taken as the main basis to synthesize a number of parameters which can reflect the characteristics of deep gas synthetically based on the data of geology, gas detection, geochemistry and logging. The two-dimensional plates of each block are drawn by using computer technology, Gas comprehensive automatic interpretation evaluation software system. According to the characteristics of deep gas, distribution characteristics and gas reservoirs in Dongpu Depression, three gas-bearing blocks in eastern (Duzhai, Qiaokou and Baimiao), central (Pucheng), western (Mengju and Liuzhuang) , Respectively, to establish a deep gas identification standards.
