Definitions
- the present invention relates to a device for handling drill rods, in particular for oil, in an installation of the type in which the rod rotation drive system is placed directly under the suspension hook.
- Such an installation is for example described in the patent of the UNITED STATES n ° 4262693.
- An object of the invention is to avoid any manual intervention.
- Another object of the invention is to provide a device making it possible to automatically compensate for the variation in length of the drill string, resulting from unscrewing or screwing during drilling operations.
- the subject of the invention is a device for handling drill pipes comprising, suspended from a hook of a block, a motor associated with a reduction gear and driving in rotation around its axis a vertical hollow shaft connected to a supply pipe.
- drilling mud characterized in that said hollow shaft is connected to a tubular end piece threaded at its lower part so as to be able to be screwed onto a drilling rod, by means of a means making it possible to vary the length of the drill string, the device further comprising, arranged in the extension of the end piece, a set of retractable claws and a set of pads making it possible respectively to support and immobilize the drill string in rotation, this set of claws and pads being guided against guide members fixed in rotation and linked to a protective casing of the assembly fixed at its upper part to the reduction motor assembly, which assembly is immobilized in rotation by a s connecting system with jack and connecting rod allowing lateral movement of the entire device and connecting it to a carriage sliding along fixed vertical tracks.
- said means making it possible to vary the length of the drill string comprises a jack comprising a cylinder integral with the hollow shaft and an annular piston driven in rotation with the shaft and capable of carrying out translational movements parallel to said axis, said piston being extended out of the cylinder by said part (tubular end, the hollow shaft and the annular piston having vertical grooves preventing rotation of the piston around the shaft.
- a valve is interposed between the annular piston and the tubular end piece.
- a train 3 of rods must be extended by a set 4 of preassembled rods (three rods for example) using the device of the invention.
- the device also makes it possible to dismantle a rod or a set of rods from the drill string.
- the preassembled rod assemblies such as that shown 5 are stored vertically in an area 6; the device 7 for driving and handling the rods is suspended from a hook 8 placed at the top of the derrick, the hook itself being fixed to a muffle 8A.
- the drive and handling device 7 and the yoke of the muffle 8A are fixed by means of jacks 9 and connecting rods 100 to movable carriages 10 along fixed vertical tracks 11. This connection prohibits the rotation of the device 7.
- FIG. 1 a pipe 13 for supplying drilling mud is distinguished.
- the device comprises a hollow shaft 20, driven in rotation by a motor 21, preferably hydraulic.
- the mud from the conduit 13 passes through the shaft 20.
- the rectangle 22 represents a speed reducer of known type which is not part of the invention and which it is not necessary to describe in detail.
- the handling device comprises a rotary actuator consisting of an annular piston 24, which can be driven in rotation with the hollow shaft 20 and which can move in translation parallel to the axis of the shaft, and a cylinder 26 fixed to the 'tree 20.
- the annular piston has grooves 25 parallel to the axis of the shaft; the tree has corresponding grooves. This double set of grooves thus allows the movements announced above.
- the piston 24 extends out of the cylinder 26 by a rod tube 25A to which is fixed, by means of an adapter part 30 a ball valve 31, hydraulically controlled and fixed to an annular support 32.
- This valve allows control of eruptions and also prevents the mud from falling on the head of the floor staff when the stems are removed.
- an end piece 33 which has an external thread 33A complementary to that which presents internally the bulged end 4A (called in English tool-joint) of the drill rod 4 to be handled.
- the mobile assembly described above is protected by a fixed casing 35 linked at its upper part to the motor 21-reduction unit 22 and produced in several elements assembled by fixing rings 37. On this casing two sets are fixed to cylinders.
- the first set includes a group of jacks whose pistons are referenced 41A and the cylinders 41 B. Each piston is extended by a part 41 C to which is attached a hook or claw 42.
- the conical shapes complementary to the hook and to the cylinder allow the hooks to approach or move away from the axis, the cylinders 41 B being fixed to the casing 35 and serving as a guide member for the hooks 42.
- the simultaneous movement of the hooks thus makes it possible to maintain the drill string by hooking under the bulged part 4A of the drill string.
- the second set includes a group of jacks whose pistons are referenced 43A and the cylinders 43B.
- Each piston is associated with a part 43C which acts on a shoe 44; the complementary conical shapes of the pads and of the cylinders allow energetic tightening of the end of the rod 4, the cylinders 43B also being fixed to the fixed casing 35 and serving as a guide member for the pads 44.
- the operation of the device is as follows, when it is desired to hang a new set 4 of rods on the train 3, which is immobilized at the level of the floor according to a known technique.
- the device 7 is brought above the zone 6 where the rods (or sets of rods) are stored.
- the device (motor 21 stopped) is lowered so as to cover a rod, which is facilitated by the cone 48 at the base of the device.
- the actuator 41A - 41 B is actuated to grip the assembly which can then be moved from the storage area to the vertical of the train 3.
- the end 4A is then strongly blocked by actuating the jack 43A - 43B; then the engine is started so as to rotate the mobile assembly 20 - 24 - 32 - 33, which has the effect of screwing the end 33 to the end 4A of the rods 4.
- the engine is then stopped and the end 4A is released by loosening the pads 44 by maneuvering the cylinder 43A - 43B in the opposite direction.
- the motor 21 is then restarted to screw the lower end 4B of the assembly 4 to the rod train 3 (see FIG. 1).
- the cylinders 41A-41 B and 43A-43B then release the set of rods 4 and drilling can resume by restarting the motor 21.
