摘　　要：煤层气与常规天然气有较大差异,采用压裂施工可达到煤层气开发的理想效果。根据煤层气的特性,在施工中应注意压裂液、煤粉、压实性等因素所造成的伤害。Coalbed methane（CBM） is a kind of self-generating and self-preserving,unconventional natural gas which stores in the coal seams and its surrounding rocks.Development and mining of coalbed methane can not only relieve pressure on energy supply but also protect the environment,and make sure the production safety,which are all of great significance.Fracturing of CBM wells can connect bore and natural fracture system together more effectively,avoid formation damage near the wellbore,and increase the speed of drainage.This paper begins with the definition,necessity of hydraulic fracture method,then introduces the hydraulic fracture characteristic,and at last points out the existing problems.
