摘　　要：在论述节点分析方法原理的基础上,论述了适合气井节点分析的流入动态模型和流出动态模型,并结合两种动态模型原理编制了计算机程序,以实例说明了气井节点分析方法在采气工程方案设计中的应用,即利用节点分析方法估算气井无阻流量、确定油管尺寸选择范围等,对采气方案中优化选择油管提供了可行的设计方法。Based on the explanation of the nodal analysis method,inflow models and discharge performance models that are suitable for the nodal analysis are discussed.Computer programs based these two models are designed,and real cases are used to illustrate the applications of the nodal analysis method in the design of gas production plan.That is,the nodal analysis is used to estimate the absolute open flow potential of gas wells and determine the range of the size of tubing.This is a feasible method for optimizing the selection of tubing in the design of gas production plan.
