Abstract
In order to study the propagation law of fracture more clearly,in this paper,the governing equations of phase field,fluid flow and fracture are derived by combining the fracture phase field method with the fluid-solid coupling theory,the propagation state of hydraulic fracture is simulated,and the pattern of fracture propagation and the change of pressure at injection point are analyzed by changing the horizontal in-situ stress difference of matrix and the viscosity of fracturing fluid.关键词
