摘　　要：为了选择合理的齿轮箱内部零件和润滑油,对稠油热采螺杆泵地面驱动装置的温度场进行分析研究。根据螺杆泵地面驱动装置的结构,建立了驱动装置热分析的有限元模型。当驱动装置表面与空气的对流换热系数为5 W/(m2·℃)时,研究4组不同环境温度(50.0、70.0℃)和封井器处温度(300.0、350.0℃)下驱动装置的温度场分布,得到了其整体及轴向剖面(减速箱长度方向)的温度场分布规律。根据有限元计算结果,对驱动装置的结构进行优化,结构优化后的驱动装置在原油温度350.0℃、环境温度70.0°及对流换热系数10 W/(m2·℃)时,电机最高温度为110.0℃,基本满足要求。To make a rational selection of the internal parts of gear box and lubrication oil, the temperature field of the ground driving device for heavy oil thermal recovery screw pump was studied. According to the structure of the pump ground driving device, the finite element model for the thermal analysis of the device was established. When the convective heat transfer coefficient of the device surface and air is 5 W/ （m^2 . ℃ ） , the temperature field distribution of the device was studied under four groups of environmental temperature （50.0, 70.0 ℃ ） and well-plugging device temperature （300.0, 350.0 ℃ ） . The temperature distribution law of the overall device and axial profile （gearbox length direction） was derived. According to the finite element calculation, the device structure was optimized. The maximum temperature of the electric motor of the structurally optimized device was 110.0 ℃ when the crude oil temperature was 350. 0℃, the environmental temperature was 70.0 ℃ and the convective heat transfer coefficient was 10 W/ （ m2 . ℃ ） . This basically satisfies the requirement.
