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.
