为估算海上油井的热损失，将多种流体视为真实的气体混合物，取代传统模型中的理想气体假设，建立了海上油井多流体注入热水流动与传热分析模型。用渤海海上油田实测数据对模型进行验证，模型计算与实测数据吻合较好，压力平均相对误差约为0.7%，温度平均绝对误差约为1.4 °C。通过模拟井筒，分析了影响海上油井热损失的因素。结果表明，在不同的注入参数下，多种热流体向环境散失的热量为2.3%~ 9.5%，其中向海水散失的热量占主导地位。注水速度、注水温度、热水比例和保温管对海上油井热损失影响较大，而注水压力、注水时间和环境温度对热损失影响较小。增加注水量、热水比例和保温管深度，或降低注水温度和保温管导热系数，均能减少热损失，尤其是减少排海热损失。
For estimating heat loss of offshore well, an analysis model of flow and heat transfer for hot water with multiple fluids injection in offshore well was established, in which multiple fluids were regarded as real gas mixture replacing the ideal gas-assumption in conventional models. Validation of the model by measured data in Bohai offshore oilfield showed that model calculation agreed with the measured data, the pressure average relative error was about 0.7%, and temperature average absolute error was about 1.4 °C. Through a simulation wellbore, the influence of some factors on heat loss of offshore well was analyzed. It was found that the heat of multiple thermal fluids lost to environment ranged from 2.3% to 9.5% under different injection parameters, and heat lost to seawater was dominant. The injection rate, injection temperature, hot water proportion and insulated tube have a great effect on heat loss of offshore well, while injection pressure, injection time and environment temperature have little effect on heat loss. An increase in injection rate, hot water proportion and depth of insulated tube, or a decrease in injection temperature and insulation thermal conductivity, leads to a decrease in heat loss, especially the heat lost to sea.
