分析某地区地质特征的基础上建立了边水气藏单井概念模型,采用数值模拟方法研究不同大小水体情况下气井距边水的距离、气井不同生产制度和不同水气比对水侵时间和稳产时间的影响,通过研究,得出气井距边水的极限距离和合理的生产制度,从而提高气藏采收率,为同种类型的边水气藏开发提供研究思路。

With the continuous further development of water-drive gas reservoir,gas well producing water almost becomes an inevitable problem during the process of exploiting water -carrying gas reservoir.Watering out of gas wells not only easily leads to the gas well productivity falling quickly,but also may leads to the decrease of the well control dynamic reserves and the increase of the difficulties of production management.Controlling the water invasion increase rapidly is the most important problem that water-drive gas reservoirs faced with.This article is mainly about a single well concept model being built based on the dominating geologic features.Adopting numerical simulation method to study the distance between gas well and edge-water and how the different gas well production systems influence on the time of water invasion as well as the time of stable production.Through studying,we can conclude that utmost distance from edge-water and optimization allocation of single well, thus improving the recovery efficiency of the gas reservoir.
