深部煤层气井压裂工艺研究及应用

Research and application of deep coalbed methane well fracturing technology

深部煤层气储量庞大、分布较广,然而煤层毛细裂缝联通性差、渗透性差,以至于传统开采方法的应用存在局限性,所以作为增产手段的煤层气井压裂工艺变成了关注的焦点。以文献研究法为主,结合实践体会与认知,重点对深部煤层气井压裂工艺展开探索,并将相关工艺要点给予简要总结,力求能使我国深部煤层气资源得到合理开发和利用。

Deep coalbed methane reserves are huge and widely distributed,but the connectivity and permeability of coal seam capillary fractures are poor,which limits the application of traditional mining methods.Therefore,as a means of increasing production,coalbed methane well fracturing technology has become a focus of attention.This article mainly adopts the literature research method,combined with practical experience and cognition,focusing on exploring the fracturing technology of deep coalbed methane wells,and briefly summarizing the relevant process points,striving to promote the rational development and utilization of deep coalbed methane resources in China.
