摘　　要：针对电潜泵在起、下泵作业过程中电缆卡子落井的问题,研制了电缆卡子打捞器。该打捞器由上接头、中心杆、顶丝、打捞篮和下接头组成。现场试验结果表明,打捞器整体结构简单紧凑,它连接在电动机下部,随同电潜泵完井管柱一起下井,无论是下泵还是起泵,只要有卡子脱落,就能捞获落物;作业时安装、拆卸及更换方便,适应性强,具有良好的推广应用前景。To solve the problem of cable grip dropping down the borehole during the running and pulling of electric submersible pump(ESP),the cable grip fisher is developed. The fisher is composed of upper connector,mandrel,top thread,dishing basket and lower connector. The field test result shows that the fisher owns simple and compact structure,and it is run down the borehole together with ESP string by connecting below the electric motor. It can fish the fish as long as there is any grip dropping down the borehole. Its installation,dismantling and replacing are simple. It has strong adaptability,showing widespread application value.
