摘　　要：压裂水平井技术是实现油气田经济开发的重要手段之一,而试井分析技术是压裂水平井的关键技术。在分析国内外压裂水平井试井模型和试井解释方法发展现状基础上,研究了压裂水平井多裂缝系统试井模型和解释方法,并分析了其压力动态特征。采用解析解与数值解相结合的半解析法构造渗流数学模型,并针对边界复杂情况,在模型中引入裂缝离散化机制。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.
