煤层气是煤在生成过程中产生的一种伴生产物,具有清洁环保的特点。目前来说,我国煤层气资源主要集中于中高煤阶含煤区,并且已经逐步提高了开采与利用成效。但是会经常出现由于煤层气排采设备选型设计不合理,而影响煤层气顺利开采的现象。因此笔者在深入调查的基础上,对我国目前煤层气勘探开发实践和技术进行分析和总结,以及结合煤层气的特征,来提出了适合我们国家煤层气开采工艺和设备优选策略。
Coalbed methane is a concomitant product of coal produced in the process of production, with the characteristics of clean and environmental protection. At present, China’s CBM resources are mainly concentrated in coal areas with high coal rank, and the effectiveness of mining and utilization has been gradually improved. However, due to the unreasonable selection and design of coalbed methane drainage equipment, it will often affect the smooth exploitation of coalbed methane. Therefore, on the basis of in-depth investigation, the author analyzes and summarizes the current practice and technology of CBM exploration and development in China, and combines the characteristics of CBM to propose a strategy suitable for our national coalbed methane extraction process and equipment.
