正确识别构造软煤及其分布规律，对煤层气产能评价及勘探选区意义重大。以延川南煤层气田勘探开发原始资料为基础，根据测井曲线，结合钻井取心资料，提出利用测井资料判识煤体结构的方法。将延川南煤层气田煤体结构划分为硬煤(包括原生结构煤，碎裂煤)和构造软煤(碎粒-糜棱煤)2种类型，并绘制了煤体结构分布图。在此基础上，探讨了构造软煤的分布特征及地质控制因素。结果显示：煤体结构受构造和沉积的控制，构造对其的控制作用更加明显。

Based on the original exploration and exploitation data, using the log and drilling core data, the authors have divided the coal texture into two types, i.e., hard coal and soft coal, and drew the distribution map. On this basis, we have analyzed the coal texture distribution characteristics and their geological controlling factors. The goal is to avoid strongly crushed coal reservoir and the area of bad fracturing effect for coal gas exploration.
