摘　　要：由于普通打捞矛只有1-3 mm的打捞范围,对于内径不确定的非常规落鱼,打捞作业中经常出现多次起下钻的试打捞作业现象．增加了作业时间及成本。为此,胜利油田研制了可退式大范围打捞矛,单组卡瓦打捞范围扩大到1-20mm,同时具备可退功能。现场应用表明,可退式大范围打捞矛能有效提高非常规落鱼的一次打捞成功率,具有较好的应用价值和推广前景。The fishing range of ordinary spears is only from one to three millimeters, so some trial fishing operations often need, which increases fishing time and cost. Regarding such scenario, Shengli Oilfield develops a wide-range backward spear with a fishing range of up to 20 mm. In addition, it can be retrieved. Its field applications indicate that the novel spear can effectively improve fishing success ratio for an abnormal fish, and has better applicable value and application prospects.
