摘　　要：在节点分析(流入动态曲线通过拟压力二项式获得)的基础上,结合物质平衡方程,对CH异常高压气藏气井稳产期进行了预测。与传统的类比法和数值模拟方法相比,该方法简单、快速、准确,可为异常高压气藏早期评价提供技术支持。The stable production periods of gas wells in CH reservoir with abnormally high pressure are predicted by combining the node analysis （its inflow performance curve is derived from the pseudopressure binomial equation） with the material balance equation. Compared to the traditional methods such as analogy and numerical simulation, this approach is more simple, more rapid and more accurate, probably providing a technieal support for the early evaluation of gas reservoirs with abnormally high pressure.
