摘要: 将气藏物质平衡方程与二次产能方程相结合,联立求解气井流压,与实际生产过程中的流压曲线进行拟合,拟合过程中采用改进的Gauss--Newton优化算法,并且进一步计算探井试采阶段动态控制储量。由于提出的方法考虑了井底压力的变化,计算结果更能反映试采过程中的动储量。

关键词: 物质平衡方程, 气井, 动态, 储量

Abstract: The calculated gas well flowing pressure by integrating material balance equation for gas poor with binonial productivity equa-tion is matched to real flowing pressure curves from production history by modified Gauss-Newton method. Dynamic proved reserves of a gas well in pre-production phase are also estimated. The study shows that the integrated method proposed considering bottomhole pressure change more properly reflcts the dynamic reserves in pre-production phase.

Key words: material balance equation, gas well, performance, reserve
