煤层气地球物理测井技术发展综述

A Summary of the Development of Geophysical Logging Techniques for the Coalbed Methane Reservoir

煤层气地球物理测井明显有别于常规的油气藏地球物理测井,本文在大量文献调研的基础上,基于国内外煤层气地球物理测井技术的发展现状,综合评述了常用的煤层气测井方法、技术系列与煤储层测井评价技术及其优缺点,总结了当前国内外煤层气地球物理测井的应用研究与发展现状,并指出其当前面临的困难和若干问题,分析了煤层气地球物理测井技术的应用前景及今后值得注意的几个发展趋势。

The coalbed methane logging methods are quite different from the normal oil-gas logging. Based on the development of geophysical logging techniques for coalbed methane both in China and abroad, the authors made a comprehensive analysis of data acquisition and evaluation techniques of geophysical logging for the coalbed methane reservoir, dealing with the logging methods, the technical systems and the technologies and contents of logging evaluation process, as well as their strongpoints and shortcomings. This paper has summarized the situation of current application research and discussed some problems concerning geophysical logging for e-valuating coalbed methane reservoirs and future development orientation related to well logging for coalbed methane reservoirs in China.
