煤层气钻井多功能性及其综合效益研究

Study on Multi-functionality and Comprehensive Benefits of Coalbed Methane Drilling

开发利用煤层气可以保证煤矿的安全生产,优化我国的能源结构,改善大气环境,对于实现我国国民经济又好又快的发展具有重要的意义。本文针对煤层气钻井的多功能性进行了重点分析,提出了煤炭资源勘探、煤层气资源勘探、采煤前抽采、采动中抽采、采煤后抽采、瓦斯排放孔、井下制冷通道等一孔多用方案,并对其综合效益进行评价,为煤层气开发利用提供了一种新的思路。

The development and utilization of coal bed methane can ensure the safety of coal mine production,optimize national energy structure and improve the atmosphere environment.It is significant for promoting sound and rapid development of the national economy.This paper mainly analyses the multi-functionality of coal bed methane drilling,proposes a multi-hole program of exploration of coal resource and coal-bed resource,extraction before coal mining,extraction when coal mining,extraction after coal mining,gas drainage and underground cooling channel,and then evaluates its comprehensive benefits.It provides a new idea for coalbed methane development and utilization.
