| 摘 要： | 井筒多相流体的物性参数和流变特性参数等均是温度的敏感函数,因此.精确计算井筒多相流体的温度分布是准确预测其压力分布、进行油井生产参数优化设计和工况分析等的重要基础.文中基于两相流动力学和传热学理论,建立了垂直井简及其周围地层温度场的数学模型.依据建立的模型,编制了不同开采工艺下的井筒温度场计算程序.并对单相和两相流体流动下的井筒温度场进行了计算与对比分析.

| Abstract: | The physical property and rheological behavior parameters of the multiphase flow in the wellbore are sensible functions of temperature.Hence,exact calculation of temperature distribution is the significant basement of forecasting its pressure distribution,proceeding optimization procedure and analysis of its behavior.Based on multiphase flow mechanics and thermal conduction theory,the thesis establishes a mathematical model which includes steady-state heat transfer in the wellbore and unsteady-state heat co... |
