我国煤层气远景资源量大,具备补充或接替常规天然气的雄厚资源基础。目前,我国投入前期试验的测试井日益增多,对煤层气开采工艺提出了新的要求。本文针对煤层气开采过程中采出水量的前期预测,泵抽设备的选择,采气过程中的防固相措施,防止水化物的形成以及采出水的处理和利用等五项关键技术作了论述。 The long-term CBM resources in China are large, with ample resources to supplement or replace conventional natural gas resources. At present, the test wells put into the preliminary tests in our country are increasing day by day, putting forward new requirements for the CBM mining technology. In this paper, five key technologies such as prophase prediction of production volume of coalbed methane, selection of pumping equipment, anti-solid phase measures during gas production, prevention of hydrate formation and treatment and utilization of produced water are discussed .
