摘要/Abstract

摘要： 为了研究煤矿区煤层气规模开发的可行性，指导该技术在煤矿区煤层气资源开发以及瓦斯治理方面的应用，文章首先以地质条件分析为基础，对官寨矿区的煤层气资源进行了评价，结果显示井田内煤层气地质条件和储层条件均相对优越，不仅煤层气储量丰富，而且气成分以CH-4为主。然后利用储层模拟软件对单井产气量进行预测，结果显示气井产量较高，连续排采15年单井平均气产量为932.00 m3/d,4号和9号煤层瓦斯含量下降33.93%和33.33%。综合分析认为官寨井田煤层气规模开发具有较好的开发潜力和安全效益。所以将地质条件分析、资源潜力评价与产能预测相结合，是一套实用性较强的煤矿区煤层气规模开发可行性研究方法。

Abstract: To study the feasibility of developing coalbed methane in coal mine and give guideline to application of this technology in coalbed methane development and gas control in coal mine, this paper evaluates the coalbed methane resource of Guanzhai coal mine based on its geology. Guanzhai coal mine has favorable geology and reservoir for coalbed methane with abundance of coalbed methane. Reservoir simulation software was used to forecast the single well gas production with result showing a higher rate, up to 932.00 m3/d in continuous 15 years. Gas from No.4 and No.9 coalbed decreased by 33.93% and 33.33%. Guanzhai coal mine has potential of large scale production of coalbed methane, and relatively safe. This feasibility study, combining geology and resource potential with production forecast, is effective in simulating coalbed methane in coal mine.

Key words: geology, coalbed methane resource, potential evaluation, forecast of production capacity
