煤层气井油管产水产气工艺排采的开发实践

Development Practice of the Drainage and Production Process for Producing Aquatic Gas from Tubing in Coal Bed Gas Wells

针对煤矿煤层气井的排水采气工作看,通常使用油管排水、环空产气的排采技术,不过实际应用中易存在井口漏气的问题,如何有效对煤层气井的排采工艺进行优化,便成为当前很多煤矿企业需要考虑的问题。为此,本文会结合案例对具体的漏气问题进行讨论,并对实际的排采工艺进行优化,以期望可以满足煤矿企业的发展需要。

In view of the drainage and gas production of coal-bed gas wells in coal mines,the drainage and production technologies of tubing drainage and annular gas production are usually used,but the problem of gas leakage at the wellhead easily exists in practical applications.How to effectively optimize the drainage and production process of coal-bed gas wells has become a problem that many coal mining enterprises need to consider at present.For this reason,this paper will discuss specific gas leakage problems in combination with cases,and optimize the actual drainage and mining process in order to meet the development needs of coal enterprises.
