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 ,并可进行注气系统的参数优选和配注方案编制等工作 The mathematical model of gas injection well joint system was established by using the theory of gas recovery calculation, and the actual production data of gas injection well of a certain oilfield was taken as an example to calculate and plot the results. The results show that the measured and calculated values ​​in gas injection well basically agree The model can be used to draw the dynamic curve of gas well, predict the gas injection capacity of gas injection well and calculate the pressure loss in different process stages of gas injection system, and can also carry out the parameter optimization of gas injection system and the preparation of dispensing scheme
