摘　　要：为提高膨胀尾管悬挂器的悬挂力和膨胀过程中膨胀锥与膨胀本体的润滑性能,对膨胀尾管悬挂器的膨胀结构进行了改进,在膨胀本体外壁镶嵌金属块提高其悬挂能力;通过在膨胀本体内表面和膨胀锥表面预涂固体润滑涂层,提高其润滑性能,降低膨胀力。膨胀尾管悬挂器膨胀试验表明:膨胀本体镶嵌单组金属块的悬挂力达到200kN,与未镶嵌金属块相比提高了3倍;预涂固体润滑涂层后膨胀力为268kN,与未经过润滑相比降低了21%。这表明,在膨胀本体外壁镶嵌金属块可以提高膨胀尾管悬管挂器的悬挂润滑性能,在膨胀本体内表面和膨胀锥表面预涂固体润滑涂层的方法可以改善悬挂器的润滑性能。In order to increase the hanging force and improve the performance of lubrication between expansion cone and body of the expandable liner hanger,the expansion structure was redesigned.For example,metal was inlayed into the outer wall of expansion body to increase its hanging force;solid lubrication coat was applied on the inner surface of expansion body and the surface of expansion cone to improve the lubrication performance and decrease the expansion force.The expansion experiment suggested that the hanging force of expansion body with single inlayed metal was up to 200 kN,which was 3times that without inlayed metal,and the expansion force with solid lubrication coat was 268 kN,a decrease by 21%.The research showed that these two methods were effective to improve the expansion and hanging performances of the expandable liner hanger.
