摘　　要：根据不稳定温度场热传导原理,采用空间三维模型分析了入井液体或井内中的液体返出过程中携带热量温度的变化规律,建立了注水管柱温度场数值计算模型,并讨论了注水管柱在不同工况下的温度分布及工况发生变化时所引起注水管柱温度变化的相关计算,为开发注水管柱力学分析仿真软件,计算注水管柱温度分布及温度的变化量奠定理论基础,具有较高的理论意义和实用价值。On the basis of the instability temperature field heat exchange theory,the transformation disciplinarian of the tem-perature was analyzed by using the three dimension space model when the liquid takes the heat quantity during flowing into the well or flowing out from the well,and the temperature field numerical computation mode of the injection string was set up.At the same time,the computation about the temperature distributing of the in-jection string in different work condition and the temperature varia-tion of the injection string when the work condition changes were discussed.All those provide the theory for developing the simula-tion analysis software of injection string,and it is valuable in prac-ticality.
