同常规油气勘探和开发应用一样,测井也应成为煤层气评价的有力工具。但是,煤层气的储集、产出机理与常规油气藏大不相同,目前的研究水平尚难建立一套完善的煤层气解释方法或方程。借助于神经网络技术进行煤层气测井评价,是现阶段的优选方法之一。

As well as the application of conventional hydrocarbon exploration and development ,the well logging should be an important measure to evaluate coalbed gas. However , as the big differences between the mechanism of reserve and production of coalbed gas to conventional oil and gas reservoir exists ,so a set of interpretation method and equation of coalbed gas is difficult to be made. The evaluation of coalbed gas logging with nerve network is one of the optimum method at present.
