SAFETY MECHANISM FOR INSTALLATION IN SOIL-SAMPLING TOOLING, WITH A SYSTEM FOR BLOCKING THE ESCAPE OF GAS/OIL IN THE STAGE OF RECOVERING THE INTERNAL TUBE CONTAINING THE SPECIMEN

摘要

“SECURITY MECHANISM FOR INSTALLATION IN SOIL DRILLING TOOLS, WITH GAS/OIL LEAKAGE LOCKING SYSTEM ON RECOVERY STAGE OF INTERNAL TUBE CONTAINING TOKEN”, where a mechanism for installation on drilling equipment tooling (which uses barrel for the continuous token extraction), be developed with a cable gland assembly (1), connectors (22), (32) and valve (42). With such elements, the mechanism offers a sealing system that prevents, in the recovery step of the inner tube with the token, that there is oil or gas leakages. The mechanism also has an additional safety device (52). Thus, the tooling typically used for ore survey (simpler and cheaper) may be used in wells for gas/oil drilling, bringing remarkable benefits in the segment, both in operationally and commercial level.

主权项

1) “SECURITY MECHANISM FOR INSTALLATION IN SOIL DRILLING TOOLS”, characterized by on cable gland (1) comprising base (2) having inner housing (3), with lower connector recess (4) receiver of support (5) of concave cradle (6) for coupling of the conical tip (7) of a mordant (8) deformable, on which rests superiorly a bipartite actuator (9) with sides (10) and (11) joined by ring spring (12), said base (2) receiving the support of the end of a helical spring (13) surrounding the upper portion of the bipartite actuator (9) and the lower neck (14) of a plunger (15), provided with stop (16), wherein said helical spring (13) anchor its opposite end, whereas the upper neck (17) of said plunger (15) passes over the hole (18) of a cylindrical jacket (19) having oil entry (20), and at its connector recess (4) the base (2) receives the upper nozzle coupling (21) of a “Y” connection (22), whose oblique nozzle (23) is sealed by a repair kit (24) for a hollow ball valve (25) and provided with a cutout (26) which is aligned to the passage (27) of a glove with threaded nozzle (28), key receiver (29), whereas, at its lower right nozzle (30) the “Y” connection (22) receives the nozzle (31) of a false swivel connector (32), in which cylindrical body (33) is housed in a ball set (34) and sealing rings (35) locked in the grooves (36) of the neck (37) of a cylindrical body (38) with the bottom nozzle (39) which is threaded to the threaded terminal (40) of the glove (41) of a safety valve (42) provided with inlet (43) for a key (44) and which receives a repair kit (45) for a hollow ball valve (46) with cutout (47), said repair (45) mounted in the housing (48) of the threaded neck (49) of a cylindrical body (50) with the threaded lower nozzle (51).
