摘要
苏里格气田渗透率低,非均质性明显,单井产能稳定性差,因此本文采用以下方法进行产能评价。首先分别按照动静结合法和综合分类法将苏14井区进行了分类,得到基本一致的结果。然后建立气井的产能方程,用的是关放曲线法和一点法,再应用这两种方法计算分类后的无阻流量。最后计算各类井平均单井控制储量。
Sulige gas field has low permeability and obvious heterogeneity,so single well productivity stability is poor.In this article,different methods were used to evaluate productivity.Firstly,No.14 area in Sulige gas field was classified by dynamic-static method and comprehensive classification method,respectively.And consistent results were gained.Then the productivity equation was established by curve method and one point method,and the two methods were used to calculate open-flow capacity.Finally,the average single well controlled reserve was calculated.
