摘要
压裂是煤层气增产的主要措施,但是,此技术并不适用于所有煤层。我国煤层气的开采处于初始阶段,煤层渗透率低,压裂技术广泛应用。因此,需要分析煤层气压裂井的增产机理及其开采特征,结合已开发煤层,分析压裂井的适用性,从而指导后续煤层气合理开采。
Fracturing is the most effective method to enhance recovery of CBM.But,this technique doesn't apply to all coal layers.It is the beginning stage of developing CBM for our country and fracturing is widely used because of low permeability.Therefore,analyze the enhanced recovery mechanics and the production characteristics in this paper.Combined with developed coalbed methane reservoirs,analyze the applicability of fractured wells so that guide subsequent work.
