摘要
文章详细地分析了川南矿区气井递减的原因,用指数、灰色系统等方法研究了川南矿区气井递减的规律,并进行了动态预测(包括单井产气量、井底压力、累积气水的单双对数分析与预测),得到了较高精度的预测结果。将其编制成计算机程序,使气井动态分析计算机化。最后详细地分析了气井的出水特征,并进行了分类。
With exponential function and grey system methods, a preliminary research on the decreasing law is carried out that is governing some gas wells in South-Sichuan mining area. Some reasons influencing a behavior of producing gas wells are given in this paper At the same time, some prediction values are calculated which include gas production and bottomhole pressure of the gas wells. The results abtained are accurately. Finally, the character of gas well watering is discussed in detail. All calculation results are get by computer and accepted by South—Sichuan mining area.
