Well Testing Analysis of Fractured Horizontal Well

LI Shu-song,et al.(Southwest Petroleum Institute,Chengdu 610500,China)  
Fractured horizontal well technology is an important method of economic development of oil field.Well testing is a key technology of fractured horizontal well.Based on actual development of well testing model and interpretation method of fractured horizontal well both at home and abroad,this paper studies well testing model and interpretation method of fractured horizontal well with multiple fractures,and analyzes pressure performance characteristics.It uses semi-analytical solution of combination between analytical solution and numerical solution to construct flow model in porous media,and introduces fracture discrete mechanism in model aiming at complicated boundary cases.
