摘　　要：针对稠油热采过程中大量低温余热资源的浪费问题,提出了利用热泵技术回收油田污水余热用于稠油伴热管道输送的工艺,并运用Matlab-Simulink软件对该工艺进行了动态仿真模拟,得到了工艺系统的制热系数。研究结果表明,该工艺系统的制热温度可达75℃,能满足稠油输送伴热水温度的要求,且系统平均制热系数为3.5。在此基础上,还进行了能耗分析。分析结果表明,所设计的基于热泵技术的余热回收系统可比锅炉加热方式节省标煤17t/a,减少向空气中排放的污染物0.714t/a,具有非常大的经济效益和环境效益。Considering the large resource of low temperature waste heat in heavy reservoir thermal recovery process, the technology of recover waste heat in oil field was used for heating pipeline in heavy oil transportation. The model of dynamic simulation system of the technology was established by Matlab-Simulink, and the heating efficiency of the technology system was obtained. The results of the study show that the heating temperature of system can achieve 75 ℃, satisfied with the temperature requirements of heating water in heavy oil transportation, and the heating coefficient of system is 3.5. Based on this, through the analysis of the energy that the established system model can save standard coal 17 t/a better than boiler heating model, to reduce the discharge of pollutants in the air 0. 714 t/a, the system has a large economic and environmental benefits.
