| 摘 要： | 本使用拟三维裂缝几何形态模型，综合考虑裂缝扩展，支撑剂沉降、压裂液的流变性和滤失性，以及裂缝中的温度分布，给出了支撑剂在裂缝中运移、沉降及分布的计算方法，实例计算结果表明，用该方法可对有前置液或变砂比注入的施工进行计算。

| Abstract: | Using a pseudo three dimensional fracture model,this paper comprehensively considers the fracture extension,proppant subsidence,rheological property and filtration property of fracturing fluid,and temprature distribution in fractures and gives a method of calculating the migration,subsidence and distribution of proppant in fractures.Examples show that this method can be used to calculate the operation with the injection of preflush or variable sand/fracture fluid volume ratio. |
