摘要
排采是煤层气井开发的关键技术之一。通过分析煤层气井的排采影响因素和现场排采的试验研究,介绍了如何进行煤层气井的排采,给出了排采原则、各排采阶段过程控制的方法,并结合实例进行了说明。在煤层气探井排采中,取得了煤层气井产量的突破,日产量达到了2500m3。
Production was one of the key technologies in coalbed methane(CBM)development.This essay introduced flowback and production of CBM wells based on the analysis of the factors affecting production and the study of production testing in oilfields.It presents the principle of production and the control methods at different stages of production,which are applied in the CBM exploration wells.The production of the exploration well is raised to 2500m3/d,which leads to production breakthrough of CBM wells.
