| 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. |

| Abstract: | The calculated gas well flowing pressure by integrating material balance equation for gas poor with binomial productivity equation 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 reflects the dynamic reserves in pre-production phase. |
| Keywords: | material balance equation gas well performance reserve |
