摘　　要：运用采气实用计算理论 ,建立了注气井节点系统分析数学模型 .并以某油田气 10 1注气井的实际生产资料为例进行计算、绘图 .结果表明 ,注气井中实测值和计算值基本吻合 .利用该模型可绘制注气井的动态曲线 ,预测注气井的注气能力和计算注气系统不同过程段的压力损失 。According to the practical computation theory of the gas production, the mathematical model for the nodal system analysis of the gas injection wells is established. And caculation and plotting were made using the production data of gas injection wells No,101. Results show that the measured data matched to the computed data. The model can be used for drawing the danamic curves of the gas injection well and predicting injection ability and computing the pressure loss of the gas injecting system for each segment. It can also be applied to the field such as parameter optimization and compiling of injection project.
