针对煤层气井储层特性和压裂的特殊性，选择了拟三维模型进行水力压裂设计。针对一口具体井的资料进行了模拟计算，计算结果合理。同时就地面注液排量、压裂液稠度系数和地应力差值对裂缝几何形态的影响进行了计算和分析，并提出了相应的建议。

In consideration of reservoir charateristics and particalarity of fracturing of coal-bed gas well,a psuedo 3D fracture model is selected to design the hydraulic fracturing.A simulation calculation is performed with data from a specific well,of which the result is reasonable,at the same time calculation and analysis are conducted on the geometry of fractures based on the displacement of surface injected fluid,density coefficient of fracturing fluid and differential value of earth stress,thus related proposals are made.
