摘　　要：近年来西北油田为严格落实降本增效,深挖老区块剩余储能,在塔河区块不断部署老井侧钻,侧钻后需要下入300m左右的尾管进行封闭漏层,由于侧钻井井斜大、尾管短、重量轻,易导致丢手不易判断、固井后丢手困难以及尾管串随送入工具提出的井下故障,为此在管串中设计增加了一个配套的牵制短节,给尾管串增加一个向下30t的牵制力,防止尾管串因悬重过轻随送入工具提出,在目前所有已应用井中,悬挂器坐挂、丢手均1次成功,并且丢手显示十分明显。In recent years, in order to strictly implement cost reduction and increase ef^ciency, deep excavation of remaining energy storage in old block in Northwest Oilfield, the old well sidetracking is continuously deployed in Tahe block. After lateral drilling, it is necessary to enter about 300 meters oftailpipe to seal the leakage layer, because the sidetracking well is inclined to large. The tail pipe is short, light weight, easy to lose hands difficult to judge, difficuk to lose hand after cementing and downhole fault of tail pipe string brought forward by tool.To increase the tail string by 30 tons of holding force down, to prevent the tail string from being put forward with the tool because of the heavy and light hanging. At the same time, in all construction wells at present, the suspenders sit and hang and lose their hands. One success, and the loss of hand show is very obvious.
