机械式外割刀
WD-J型机械外割刀,常与套铣管连接,能快速有效地从管子外面割断和取出切下的管子。 适用于从管外切割的套管、油管和钻杆等。它采用弹簧自动进给在管外进行切割管材的割刀。由于弹簧自动进给,它可避免由于司钻操作失误过大拉力而毁坏割刀,割断后可与落鱼同时起出,该割刀可5″和4 1/2″钻杆,在切割不同钻杆时,需要更换相应的卡紧套。
Mechanical external cutter
The Mechanical external cutter which often connects with washover pipe, is used to cut and remove stuck
pipe in long undamaged secti***, and capable of cutting all types of stuck drill pipe or tubing or casing.
The external cutter utilized automatic spring-fed to cut tubing at the outside of the pipe. As a result of automatic spring-fed, it can be ***oided exerting over pulling force to damage cutter caused by head driller’ fault. After cutting
it can be lifted with fish at the same time. The cutter can be cut 5″and4 1/2″drilling pipe. When cutting different pipes, it would be changed proper clamping casing.
The mechanical external Cutter is simple in structure, safe and reliable in use, convenient operation, high-efficiency performance. The cutter works ***oothly, rapidly and is widely used in cutting blocked oil rode
or recutting broken catch in well. It has been proven to be the most versatile and reliable in the field.
