For a series of problem of horizontal well percolation,individual well is considered as research object. On the basis of theory of percolation mechanics, theory of transient flow of infinite diversion horizontal well is studied around the physical and mathematical models and the research approaches have comprehensively adopted percolation mechanics,reservoir engineering,modern mathematics and so on. On the basis of the research,both the line source and the bar source models of infinite diversion horizontal well in the closed top and bottom reservoir are deduced. The pressure condition is given in the time domain and in the space domain.%针对水平井渗流中一系列问题,以单井作为研究对象,从渗流力学基本理论出发,围绕物理数学模型,综合渗流力学、油藏工程、现代数学等多学科交叉的方法,研究了无限导流水平井的非稳态渗流理论.在此基础上推导了顶底封闭油藏中无限导流水平井的线源渗流模型及体源渗流模型.得到其在时间域、空间域上的动态压力分布.
