摘要： 根据气井的实际生产情况,建立了气井节点分析数学模型,给出了数学表达式。利用该数学模型,可计算不同油管直径的产气量和不同段的压力损失。根据气井的动态曲线预测气井生产气的能力,可进行气井系统指标预测、参数优选等工作。以中原油田文 23 气井实际资料为例进行了计算、分析,结果与实际值基本吻合。

Abstract: According to the actual production conditions, the mathematical model of nodal system analysis of the gas wells is established and the mathematic expressions are proposed.It can be used to calculate the gas yielding amount of different tubing diameters and the pressure loss for each segment and to predict the gas productivity based on the performance curves of gas wells.It can also be applied to do many other works for gas wells such as system's index prediction and parameter optimization, etc.The calculation and analysis are conducted by means of the field data from gas well Wen-23 in Zhongyuan oilfield.The calculated results accord basically with the real indices and parameters.

Key words: gas well, production, system, prediction, mathematical model
