测试压裂在油田开发及压裂设计方面起着至关重要的作用。水力压裂是提高低渗透油田开发效益的最有效手段之一。以Meyer提出的考虑了停泵之后裂缝的延伸、与压力有关的滤失等因素的更为综合的G函数模型为基础，分析与压力相关的滤失的G函数及其叠加导数的变化特征。以富县探区两口井测试压裂压降曲线分析为例，介绍了利用压降曲线分析求取储层参数及对储层特征进行诊断的方法。通过测试压裂分析为大型压裂设计、施工提供可靠的依据。

Mini-frac plays a key role in oilfield development and fracturing design, and hydrofracturing is one of the most effective measures to enhance development benefits of low permeability reservoirs. Based on a more comprehensive G function model pro-posed by Meyer, which considered fracture extension after pump-stopping and filtration factors associated with pressure, this paper analyzed pressure dependent leak off G function and its superimposed derivative variation. Taking the example of two wells test drawdown and fracturing curves analyzing in Fuxian exploration area, reservoir parameters were analyzed and calculated by using drawdown curves and method for diagnosing reservoir characteristics were introduced. Test fracturing analysis provides reliable ba-sis for fracturing design and construction.
