摘　　要：煤层气储层具有多裂缝、低压力和低渗透的特点,在压裂过程中容易造成压裂液的滤失,形成短而宽的压裂缝,使压裂效果不理想。对我国煤层气储层压裂存在的难点进行定性分析,提出相应对策。同时,介绍现有的国内外煤层气储层在压裂过程中使用的压裂液、支撑剂和压裂工艺。The characteristics of the coal are natural cleats,low pressure and low permeability,which make short and wide fractures formed so that the fracturing effect is non-ideal.Qualitative analysis on the difficulties of fracturing to the CBM development is shown in this paper.And fracturing fluid,propping agent and fracturing technology which can be found many problems existing in the CBM development are introduced.

关 键 词：煤层气 水力压裂 压裂难点 压裂工艺 缝网压裂
