Abstract:
Parking and automatic handling equipment of drilling rods (10) includes a carousel (20) of containers (30) of drilling rods (40); and a rod handling system (100), positioned on a drilling machine. A handling arm (101) transfers the drilling rods (40) out of the carousel (20). The carousel (20) defines a closed path around which are arranged the containers (30) of drilling rods (40); the carousel (20) includes an internal structure (22) for supporting the containers (30) movable on a closed path.
Abstract:
A portable pipe handling apparatus and method includes providing a support structure adapted to support a pipe stand along a pipe stand building axis associated therewith, and inclining the pipe stand building axis so that an upper end of the axis is adjacent a top drive in a drilling rig mast and so that the pipe stand translation trajectory which is substantially co-axial with the pipe stand building axis intersects a hand-off window between the top drive and the pipe stand building axis.
Abstract:
A dual firing line drilling installation has a drilling tower main structure with four frameworks that are each over a major portion of their height U-shaped in horizontal cross-section. A four-sided central (11) space is present, and along each side of the central space one framework is arranged with its opened vertical side facing the central space. First and second storage devices (25,27) are provided for vertically storing drilling tubulars. The first storage device is housed in a first framework, the second storage device in a second framework. A first hoisting device is supported by a third framework of the drilling tower main structure, to manipulate a string of drilling tubulars in a first firing line (21). A second hoisting device is supported by a fourth framework to manipulate a string of drilling tubulars in a second firing line (23). A first and second pipe racker (29,31) are housed within the drilling tower main structure and adapted to move drilling tubulars while supported in vertical orientation between a storage devices and a firing line.
Abstract:
A pipe handling system reduces the amount of physical effort required for an operator to transfer steel rotary drilling pipe sections from a storage location to and from a rotary drive unit. The system utilizes an indexing arm which removes or adds the pipe sections from the storage location, placing them in the correct position to be attached to or removed from the rotary drive unit. The index arm, unlike other systems, can remove individual pipe sections to and from the storage location directly to the rotary drive unit's centerline of drilling position. This reduces both the number of physical moves required to complete the task and the amount of weight being transferred. The indexing arm is able to lift a pipe section from the storage location and place it below the rotary drive unit's centerline, then lower away from it without additional movement of the rotary drive unit itself.
Abstract:
The present invention relates to a method for installing a pipe (313) when drilling a first hole with the aid of a rock drilling apparatus (100), wherein a tool (309) which can be connected to a drilling machine (306) via one or more drill rods (308) is used in said drilling, which method comprises—drilling a first part of said first hole,—installing a pipe (313) in at least a part or said first drilled part of said first hole, wherein the method further comprises:—installing said pipe (313) in said first hole while drilling of said first part of said first hole is in progress.—pulling said drill rod (308) out of said first hole before finishing drilling of said first hole to the desired, compared with said first part, deeper depth. The invention also relates to a system and to a rock drilling apparatus.
Abstract:
A fingerboard latch assembly includes a latch configured for operational engagement with a fingerboard for lockingly retaining at least one tubular to the fingerboard. The latch is movable within a range of motion extending from at least a locked position to an unlocked position. A positioner operatively engaged with the latch is communicably couplable to a process control network (PCN), and is sized and shaped for receipt within a latch channel of the fingerboard. The positioner is configured to move the latch within the range of motion in response to signals received from the PCN, to capture position data for the latch, including the position of the latch at a plurality of points within the range of motion, and to communicate the captured position data to the PCN.
Abstract:
A device is taught for positioning drill pipe make up or break out equipment on a rig floor. The device comprises a forward arm connectable at a first end to the drill pipe make up or break out equipment, an upper rearward arm and a lower rearward arm, pivotably connectable between the forward arm and a column, said lower rearward arm further being axially movable along said column. The device further comprises means for maintaining the upper rearward arm in parallel relationship with the lower rearward arm and means for axially moving said lower rearward arm. Axial movement of said lower rearward arm acts to extend or retract said forward arm, while maintaining a constant axial position of the make up or break out equipment. A method is also provided for positioning drill pipe make up or break out equipment by connecting the make up or break out equipment to a forward arm of a positioning device and horizontally extending or retracting said forward arm while maintaining a constant vertical position of the equipment.
Abstract:
The invention relates to a tubulars storage device (1) for storing a plurality of tubulars (2a-e), said tubulars storage device comprising spaced apart fingers (3, 4) forming therebetween a slot (5), and a plurality of pivotably mounted latch members (9a-e) arranged at spaced apart locations along the slot (5). A rotary camshaft (11) is provided for pivoting the latch members (9a-e) between a closed position and an opened position. A drive (12) is provided for driving the rotary cam shaft (11) and thus pivot the latches (9a-e), one after the other, from their closed position into their opened position. In a final angular position of the cam shaft, all latch members (9a-e) are retained, preferably by opening cams, in their opened position, and are thus all effectively locked in this position, located out of the path of displacement of tubulars (2a-e), thereby allowing displacement of the tubulars along the slot (5).
Abstract:
A device for tripping, in which, at a drill-floor opening which is arranged to receive a pipe string, two or more cooperating pipe-handling units are arranged, each, independently of the other(s) or in cooperation with the other(s), being arranged to releasably hold the pipe string fixed and to move the pipe string in its axial direction, and also to move a pipe section in the axial direction of the pipe string and rotate the pipe section around the axis of the pipe string.
Abstract:
An offshore platform may include a pair of trolleys. One trolley may be mounted on top of the platform and the other trolley may be suspended below the platform. Each trolley may be positioned on opposed sides of a moon pool in one embodiment of the present invention. The lower trolley may be used to hang off a riser and blowout preventer. The upper trolley may be utilized to hang off smaller diameter casing while larger diameter casing is being made up and positioned within the hole. As a result of the parallel operations made possible by the trolleys, drilling time may be reduced in some embodiments.
