构造煤地球物理测井判识研究

摘要

Identification of soft coal with geophysical logging is not only the base of coal and gas outburst evaluate, but also the pursuant of well location select in CBM development. The paper analysis the geophysical responses of soft coal both from laboratory and field, and give out the judging standards by hole diameter and resistivity finally.%测井方法判识构造煤是地勘阶段评价煤与瓦斯的基础，也是地面煤层气开发井位选取的依据。本文从实验室参数测定和现场数据统计两个方面综合分析了构造煤地球物理相应特征，指出了利用井径和电阻率联合判识构造煤的准则。
