摘　　要： 中深致密气藏是非常规天然气储量的重要组成部分,也是未来能源开发的重点。通过分析气藏地质特征,提出了应用压裂水平井技术开采中深致密气藏的设想,并且结合中深致密气藏的高温、高压、层深和岩性致密的特点,重点研究了压裂水平井多裂缝系统的渗流数学模型和压力动态特征,采用解析解与数值解相结合的半解析法构造了渗流数学模型。 Mid deep tight gas reservoir is the important part of non-conventional gas reserves, also is importance of future energy resource exploitation. The paper brings forward an idea of exploiting mid deep tight gas reservoir using the fractured horizontal well technology. On the basis of its geological characteristics of high temperature, high pressure, deep bury, and tight lithology, etc, this paper has focused on seepage mathemati cal model and pressure performance characteristic of fractured horizontal well with multiple fracture. In addition, a seepage mathematical model has been established using the semi analytical solution which integrates analytical solution with numerical solution.
