Method and apparatus for testing the integrity of oil delivery tubing within an oil well casing

摘要

An apparatus and method for testing the integrity of oil delivery tubing within an oil well casing includes a rupture disc holder coupled with the tubing near the lower end thereof. As successive lengths of tubing are added, the assembled tubing is subjected to a test pressure with the pressure maintained by the presence of the rupture disc within the holder. When the tubing assembly is complete, it is subjected to a higher burst pressure sufficient to rupture the disc. This opens a passage through the holder for installation of the push-pull rod and for passage of oil from the pump, which is coupled with the tubing below the level of the holder.
