摘　　要：通过分析固孔器在固孔时的受力情况,同时结合现场常用钻孔参数,设计了一种胶囊固孔器,该胶囊固孔器的胶囊材料采用综合性能高的聚氨酯橡胶,具有拉伸强度高、延展性好,承受压力较高的特点。试验表明:胶囊固孔器能有效密封孔壁,可承受的轴向压力远超实际需求。By usual drilling analyzing the force condition of the hole-fixing device under working condition and the parameters, a capsule hole-fixing device is designed. The material of the capsule adopts polyurethane which has high tensile strength and good ductility and can endure high pressure. It is proved by endure the the tests that the capsule hole-fixing device can not only seal the wall of the hole, but also axial pressure much higher than needed.
