摘　　要：在粒子冲击钻井系统中,钢球高压螺旋输送机是关键装置之一。因钢球材质的特性及输送工况与常规螺旋输送机有着很大差异,进而所造成的钢球夹卡现象(严重时导致闷车)是不容忽视的问题。文中通过试验研究,找出了钢球在螺旋输送过程中极易夹卡的位置,分析了各种夹卡现象存在的原因,对螺旋输送机的结构进行了适应性改进。The screw conveyor delivering steel particles material under high pressure is among key facilities of particle - injection system used for the particle impact drilling. The steel particles would always be got stuck is a serious problem. Because the nature of steel particles and the working conditions of screw conveyor is different from conventional screw conveyor. This article finds out where it happens, analyzes the reason and finishes the structural improvement by experiment. The paper has researched influence.
