| 摘 要： | 榆林气田南区经过9年多的滚动开发,部分井进入了产量递减期。气藏开采过程中,气井的产量递减规律通常采用Arps法、改进衰减法、HZC模型法和CH-Weibull模型法进行描述,最典型的产量递减曲线形式有指数递减、双曲线递减和调和递减3种。上述几种方法的联合对比使用,可以获得更符合实际的产量递减规律曲线,从而推导出气井产量预测方程,得到较准确的产量预测数据。

| Abstract: | Yulin gasfield in southern district,after nine years of rolling development,some wells into the production decline phase.Gas extraction process,the law of diminishing production of gas wells Arps method commonly used to improve the attenuation,HZC models, and CH-Weibull model method to describe the most typical form of the production decline curve index decrease,decreasing,and to reconcile decreasing hyperbolic 3.Contrast to the above-mentioned the joint use of several methods can get more in line with the ... |
