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.

Abstract: For the safety of fluid injection tubes with the shaft head. A fluid injection tube (1) to be used in safety locking test columns, where a fluid injection tube (1) is used in a test column (E) of a probing equipment receives a throat (6) incorporated within its lower edge, right above its nozzle with inner threads (5). After inserting the test column (E) inside the drilling shaft (P) and coupling the fluid injection tube (1), as BOP (blow out prevention system) compartments (G) are closed, the throat (6) is located right below the lower edge of such closed compartments (G). With the fluid injection, if the test column (1) is pushed and slided upwards, the fluid injection tube (1) coupled to the shaft is locked by its throat (6) under the compartments (G) lower edge With this stop locking system between the throat (6) and compartments (G) edge, the test column (E) is prevented from exceeding the traction force of compartments (G) and being expelled from the probing equipment platform.

Abstract: Fluid tube for sealing test in the BOP chamber. The test tube (1) used in the BOP chamber (C) resistance test step has its hollow structure filled internally and totally through a fluid (F) input (4). Thereby, wrapped by closing the drawers (G), after injection in the test fluid chamber (C), due to the filling fluid volume (F) internally and resulting air exhaustion into the hollow structure, the zest tube obtains a supplementary structure resistance against the pressure applied within the chamber (C), preventing unwanted distortions. The tube obtains an effective sealing due to the filling fluid volume (F) that exhausts the air within it, stopped internally with the couplings of the screwed pin (3) threads and the female thread (R) of the plug (TA) or test plug, preventing the test fluid into the chamber (C) to leak and enter its hollow structure.

Abstract: ‘PROBING EQUIPMENT PLATFORM, FITTED WITH A MOBILE LIFTING AND LOWERING MECHANISM FOR TRANSPORTATION AND LIFTING AND LOWERING SYSTEM OVER THE DRILL SHAFT HEAD’ For lifting and lowering the probing platform. The mechanism has a base (9) with brackets (12) and arms (5) running in the pantographic system, connected under the platform (1) floor (1). By the brackets (12) movement, the assembled and compacted platform (I) in a warehouse may be lifted and lowered automatically to the set over the body (C) of a dolly and taken to the surface of the drill shaft head, as it is taken off and lifted automatically as well by the pantographic system of the arms (5) and positioned for the probing procedure. As soon as the probing is concluded, the platform (1) is lowered by the arms (5) and set once again automatically in the dolly body (C) by the brackets (12), as it may be brought back to the warehouse or taken to other drill shafts, and so forth for new probing procedures.

Abstract: To lock the coating column to the probing equipment chuck. The equipment consists of a support (1) used between the probing equipment hoist and the coating tube column (for gas/oil shaft cementing). Prior to its threaded nozzle (5), the support (1) gets a collar (6) with a diameter bigger that the probing equipment chuck (M) opening radius. When the chuck cylindrical bracket (M) is opened, for inserting or removing the coating column (R) along with the drilling shaft (PO), in case of probing hoist cable (CA) breakage, as an example, the sudden lowering of a coating column inside the shaft (PO) is prevented by the collar (6) locking over the chuck (M) open cylindrical support in a stopper system. This way, expensive and time-consuming procedures for recovering coating columns (R) from the gas/oil probe drilling shaft (PO) bottom are avoided.

Abstract: “SET AND ARRANGEMENT FOR DRILLING STRING COMPOSED BY SMOOTH RODS FOR SECURITY SYSTEM AGAINST THE INFLUX IN OIL/GAS WELLS DRILLING STAGE”, where a tubular support (1) receives rubber tip (37) mounted on block composed of sealing and locking elements. The set receives, in the BOP, the overtaking of the string of smooth rods (H) of an oil/gas drilling equipment. The tip (37) will receive directly the pressure imposed by unwanted gas or fluid (G) escaping in case of influx not detected immediately. Under pressure, the tip conical wall (37) in counteraction compresses the drill string automatically causing efficient sealing, preventing unwanted gas or fluid (G) to rise and reach the platform (P). Also automatically, gas (G), by not to having where to escape, is directed by a perpendicular nozzle (4) of the support (1) for burning in remote burner far from the platform (P) until taking measures, safely, to control the influx.
