在分析研究注水管柱在不同工况下的温度分布及多工况注水工艺过程注水管柱温度计算工基础上,根据不稳定温度场热传导原理,采用空间真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。
Based on the analysis of the temperature distribution of the water injection pipe string under different operating conditions and the temperature calculation of the water injection pipe in the multi-condition water injection process, according to the heat conduction principle of the unstable temperature field, The temperature of the carrying liquid in the process of changing the law of temperature, the establishment of the water column temperature field numerical model.
