Abstract: An arrangement for a drilling string where a tubular support receives a rubber tip mounted on a block composed of scaling and locking elements. The tubular support having a perpendicular nozzle projecting from the tubular support. The tip will receive directly the pressure imposed by unwanted gas or fluid (G) escaping in case of influx. Under pressure, the tip in counteraction compresses a drill string automatically for causing efficient sealing and preventing unwanted gas or fluid (G) to rise and reach the platform (P). Also automatically, gas (G), by not to having anywhere to escape, is directed by the perpendicular nozzle of the tubular support for burning in a remote burner far from the platform (P) until taking measures, safely, to control the influx.

Abstract: To clear the probing shaft. Comprised of an assembled spin set from a vented axle (6) with seals, coupled to an upper head (34) with an eyelet (41) and fluid input (40). From the threaded lower end (7) of the axle (6) to the fluid input (40), an inner fluid passage is formed in the device. After fixing the device to the coating column (R), the latter, after finding hindrances (O) on the oil/gas shaft (P) bottom in the shaft cementing phase, will be constantly rotated around the axle (7) by the chuck (MA) of the probing equipment simultaneously to the fluid injection (F). With the spin combined to the fluid combined to the fluid injection (F), the hindrance (O) in the shaft wall (P) shall be eroded and eliminated, allowing the passage of such coating column (R) to reach the bottom in the cementing phase.

Abstract: “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.

Abstract: Fluid tube for sealing test in a BOP chamber. The test tube used in the BOP chamber resistance test step has its hollow structure filled internally and totally through a fluid input. The tube obtains an effective sealing due to the filling fluid volume that exhausts the air within it, stopped internally with the couplings of screwed pin threads and a female thread of a plug or test plug, preventing the test fluid into the chamber to leak and enter the hollow structure of the chamber. The supplementary structure anti-distortion system including air absence inside the tube and test tube stoppage the system avoids false pressure into the chamber to the sensors distributed therein, not detecting false leakages, making the BOP resistance analysis against potential oil/gas leakages precise during the probing procedure.
