注汽管线保温材料的性能影响管线保温情况，进而影响稠油油田生产能耗。通过实地调研与理论研究相结合的方法，基于TOPSIS原理建立一种优选保温材料的评价体系，通过TOPSIS原理与熵权法、层次分析法结合，优选注汽管线保温材料。%The performance of thesteam injection pipeline insulation materialcan affectthe insulation of thepipeline, soit willaffectthe energy consumption of heavy oil fieldproduction.Inthispaper,combined withthe field research and theoretical research,an evaluation system to select the insulation material of the steam injection pipeline by the principle of TOPSISwas established.Theinsulation materialcan becorrectlyselectedby combining the principle of TOPSIS with Entropymethodand AHP.
