According to the method, a pressure and yield analysis model considering the elliptical fracture transformation volume is established, an early-stage typical curve of the model is solved by using a source function solving method, and a Mathieu function is applied to the later stage for solving. The model can be applied to pressure and yield analysis of the elliptic transformation volume, and the pressure response of single medium, double medium and triple medium is solved by utilizing the elliptic flow thought, so that the analysis method of the pressure yield after the compact oil is fractured is enriched.
