GAUGE CARRIER FOR INCORPORATION INTO TUBING FOR FLOW-TESTING OF OIL AND GAS EXPLORATION WELLS

摘要

A gauge carrier comprises a tubular body (3), and upper and lower subs (2, 13). The subs (2, 13) are releasably and sealingly secured to the upper and lower ends of the body (3) and are incorporated into tubing (1, 16). The subs (2, 13) provide openings therethrough coaxial with the openings in the tubing (1, 16) but offset to one side of the axis of the body (3). In one embodiment a partition wall (7) is movably within the body (3) and can be latched in a position where it provides limited communication between a first space freely communicating with the openings in the subs (2, 13) and a second space in which gauges (8) can be releasably retained. The wall (7) can also be unlatched so that the gauges (8) can be retrieved through the openings in the subs (2, 13). In a simpler version the wall is in the form of an apertured tube mounted within the body between the openings in the subs.
