摘　　要：稠油热采领域使用的热采井口装置,其工作温度达到400℃,压力达到69MPa,虽然采取材料强度降级使用方式能够满足高温工况的要求,但是高温影响使得金属和非金属材料出现强度降低、疲劳断裂等现象,对使用带来极大的安全隐患。因此如何选择合适的材料显得尤为重要。Thermal recovery wellhead for thermal recovery of heavy oil field,its working temperature reached 400℃and working pressure reached 69MPa,Although the use of material strength degradation can meet the requirements of high temperature condition,but high temperature influence may lead to decrease of strength and fatigue fracture phenomenon of metal and nonmetal materials.The influence will cause great safety hidden trouble.Therefore,it is very important to choose the right materials.

关 键 词：稠油 热采井口装置 金属材料 非金属材料
