ABSTRACT:
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.
