摘要
本文介绍研究测井资料所形成的煤层封盖性关键参数评价技术。该技术目的是将煤层及顶底板层作为一个不可分割开来的整体,进行煤层系统综合评价与有利煤层气地层预测,打破以往仅对煤层进行研究和开采的传统模式,实现煤系地层的高效采收。
The paper introduces a technique for evaluation of key parameters of capping ability of coal seam obtained from logging data. The purpose is to regard coal seam, roof and floor layers as an insepara- ble integrity, and to carry out comprehensive evaluation of coal seam system, which is favorable to pre- diction of CBM strata.
