发明名称 Autonomous Painted Joint Simulator and Method to Reduce the Time Required to Conduct a Subsea Dummy
摘要 A system and method utilizing a painted joint simulator to reduce the time required to conduct a dummy run in order to space out subsea test equipment within a blow-out preventer. In certain embodiments, a heavy weight fluid is injected into a chamber of the joint in order to assist in its downhole descent speed. In other embodiment, a high pressure fluid is injected into a second chamber of the joint in order to force the heavy weight fluid out of the joint in order to assists in the assent back to the surface. Other embodiments include an umbrella assembly that assists in the descent or assent of the painted joint.

主权项 1. A method to determine placement of a subsea test tree (“SSTT”) within a blow out preventer (“BOP”), the method comprising: deploying a sensing joint down through a tubular and into a BOP, the sensing joint comprising: a heavy weight fluid contained therein; anda hanger positioned along the sensing joint; landing the sensing joint adjacent the BOP using the hanger; closing at least one BOP ram upon the sensing joint, thereby providing an indication of a position of the at least one BOP ram; retracting the at least one BOP ram from the sensing joint; forcing the heavy weight fluid out of the sensing joint; allowing the sensing joint to move back up through the tubular; and determining a desired placement of an SSTT within the BOP based upon the indication of the position of the at least one BOP ram.
