摘要: 井筒压力是气井生产中的重要参数,由于温度对压力计算会产生一定的影响,因此在预测井筒压力分布时必须考虑井筒温度的分布。针对开井生产和关井后两个阶段,提出不同的计算思路计算井筒温度非线性分布,在此基础上预测两个阶段与温度分布相对应的井筒压力分布。通过实例对比表明,考虑温度非线性分布的井筒压力预测结果更为准确。

Abstract: Well bore pressure is an important parameter for gas well production. The changes of wellbore temperature should be considered when predicting wellbore pressure distribution, because the temperature has an effect on the pressure calculation. This paper proposes different calculation thoughts for opening and shutting stages to analyze the nonlinear distribution of wellbore temperature, by which the corresponding distributions of wellbore pressure in two stages are predicted. The case study shows that the predicted wellbore pressure result considering nonlinear temperature distribution is more accurate.
