| 摘 要： | 凝析气井流入动态分析是气藏工程研究，节点分析及产能计算与配产不可缺少的一部分。文中指出了现有方法利用二项式产能方程预测凝析气井流入的动态的不足，认为利用测试资料回产能方程只能用于测试阶段，而当气藏压力变化后，产能方程中的回归系数均应随气藏压力，含水饱和度，相对渗透率等的变化而变化。

| Abstract: | Analysis of inflow per formance is necessary for gas engineering,nodal system analysis,productivity calculation and gas production allocation. The paper points out drawbacks of widely-used binomial formula of productivity equation. In fact,the productivity equation which is regressed by using test data applies only to test period,and the regression coefficient of productivity equation changes with the pressure of gas reservoir,water saturation,relative permeability. The paper studies the change relations among relative permeability,gas compressible coefficient,viscosity and AOF when the pressure of gas reservoir changes,and puts forward a method for determining the coefficient of productivety equation under different pressure of gas reservoir. The given case shows a bigger error in the calculation of the coefficient of productivity equation and AOF between considering pressure change and not considering pressure change of gas reservoir. |
