COILED TUBING LAP WELDS BY MAGNETIC PULSE WELDING

摘要

A method for joining coiled tubing is described. Coiled tubing joints using a magnetic pulse welder are described that retain the strength of the original tubing. This type of joint is useful for joining multiple coiled tubing sections or for removing and repairing damaged coiled tubing. Because the joint is as strong as the original tubing, these types of joints may be used when placing tubing in the well.

主权项

1) A process for joining coiled tubing comprising:
reaming a female end on a coiled tubing; reaming a complementary male end on a coiled tubing; placing the male coiled tubing in the female coiled tubing to make a coiled tubing joint; placing an electromagnetic compression coil around the coiled tubing joint; and compressing the female coiled tubing onto the male coiled tubing to form a tight weld.
