| Abstract: | The study of the seepage laws of a single fracture is the beginning of the theory of fractured horizontal wells,and based on it,the productivity and pressure performance analysis theory of horizontal wells is established gradually.This paper conducts a systematic review of the development process of the theory.The foreign research emphasizes on building up a mathematic model and using the method of source function,three linear flow model and numerical method to solve.The domestic research focuses on the productivity of fractured horizontal wells.The main methods to analyze the productivity of fractured horizontal wells include the fracture potential function distribution,conformal mapping method,fracture discrete approach,equivalent radius method,source function and green function method,and the merits and demerits of these methods are evaluated.This paper analyzes the existing problems in the seepage theory of fractured horizontal wells,and points out the development tendency of the fractured horizontal well seepage theory. |
