LXLT-B COILED TUBING OVERSHOT

31.75的连续油管具有外径小、壁薄、挠曲性好等特性。如果断落到井里 ,其打捞非常困难。在卡瓦打捞筒的基础上改进设计出LXLT -B型连续油管打捞筒。介绍其结构原理和现场试验情况。

I31.75 coiled tubing has the property of small diameter,thin wall and flexibleness,If it breaks and falls in downhole,it is difficult to fish.On the basis of slip socket,the LXLT-B coiled tubing overshot has been developed.The paper presents structure,working principle and field testing of LXLT-B coiled tubing overshot.
