摘　　要：水力压裂是开发低渗透油藏的有效增产措施。桩74块低渗透,平面上相带和物性变化大,为了提高压裂效果和裂缝数值模拟的精确度,优选出合理的裂缝参数,压裂时需要充分考虑其非均质性。本文针对桩74块的特点,应用流动单元分析法,将储层分为四类流动单元,结合数值模拟方法,优选裂缝参数,现场取得了较好的开发效果,对于改善低渗透油田的开发效果,有着十分重要的意义。Hydraulic fracturing is effective well stimulation in low permeability reservoir.Zhuang 74 unit of zhuang xi oil field is very low in permeability, and is varied greatly in facies belt and properties of layers. to increasee the effect of the hydraulic and the accuracy of fracture numerical simulation so as to optimize fracturing parameters, the anisotropy must be taken into consideration.This paper applies hydraulic unit analysis to zhuang 74 unit,divides it into four hydraulic units,combines with numerical simulation,optimizes fracturing parameters,gets better result on the spot.This method is very instructive in low permeability.
