STUDY ON MATHEMATICAL MODEL OF THREE DIMENSIONAL HYDRAULIC FRACTURING
水力压裂三维数学模型研究

According to the theory of fluid mechanics in porous media,rock mechanics,heat transferring and fracture mechanics,the mathematic model is established to characterize 3D hydraulic fracturing. Rheology of fracturing fluid,process of supporting reagent transferring,change of thermal field and coupling effect among different procedures are considered in this model. The method and numerical solution to compute crack expansion are also given. In the end,a case study is shown to verify the model.
