Background

In an oil and gas drilling system, in order to improve the working efficiency, especially the working efficiency of tripping operation, a temporary storage area of a drill rod column, namely a setback area, is usually arranged in or outside a derrick. The drill rods are joined together by two, three or four stands, discharging vertically into the stand box area.

In order to achieve the purpose, the drilling system needs to be provided with a plurality of devices such as a pipe erecting box, a pipe arranging machine, a pipe erecting mechanical arm, a rat hole, a catwalk and the like. The equipment is operated in a cooperative mode, a single drill rod is horizontally transferred to the rotary table through anchoring, the single drill rod is adjusted to be in a vertical posture from the horizontal posture by the vertical root receiving manipulator, the single drill rod is connected into a vertical root under the cooperation of the rat hole, the vertical root is delivered to the vertical root box by the pipe arranging machine, and when the vertical root needs to be placed at a well mouth, the target vertical root is taken out of the vertical root box by the pipe arranging machine, transferred to the well mouth and delivered to the top drive.

The stand box is used as a temporary stand storage device and is one of key devices for improving the working efficiency. The setback needs to have a large enough capacity to store drill rods at all drilling depths, so the setback needs to have a large enough structural size, structural strength, and rigidity to meet its operational needs. Meanwhile, the stand box is arranged at the middle upper part of the derrick, so that the gravity center height of the whole derrick is increased, and the connection reliability is met by local reinforcement. When the stand box is filled with stands, the stand load of the derrick is greatly increased; the full stand condition also greatly increases the windward area of wind load, increases the acting force of wind on the derrick, and simultaneously the area of the stand box of the drill floor also needs enough structural strength to support the weight of all stands. When emergency happens, all the stands need to be taken out of the stand box in time and disassembled into single stands to be placed in a pipe yard.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

Referring to fig. 1 and 2, an embodiment of the present invention provides a drilling rig including a derrick 2, a derrick substructure 21, a hoist system 6, a drill floor iron roughneck 5, and a pipe handling system. A hoisting system 6 is connected to the top of the derrick 2 and is used to lift and lower the tubular 4 during drilling. The iron driller 5 is connected with the derrick base 21 and used for righting and clamping the pipe 4 and carrying out the make-up and break-out. A pipe handling system is connected to the derrick 2 for storage and retrieval of the pipe 4.

Compared with the prior art, the drilling machine provided by the invention does not need to use equipment such as a derrick butt box, a pipe arranging machine, a butt mechanical arm, a rat hole, a catwalk and the like to pick and place the pipe 4, so that the load of the derrick 2 is greatly reduced, field equipment is simplified, and the storage space is saved.

Referring to fig. 3 to 18, the pipe string handling system in the present embodiment includes a pipe string handling robot 1 and a pipe string storage unit 3. The pipe tool storage assembly 3 is used for being placed on the ground and storing the pipe tool 4, and meanwhile, when the pipe tool storage assembly 3 needs to be taken out, the stored pipe tool 4 can be isolated from other pipe tools 4, so that the pipe tool processing robot 1 can take out the pipe tool conveniently. The tubular handling robot 1 is used to retrieve tubulars from the tubular storage assembly 3, to perform attitude adjustments on the tubulars 4, and then to transport the tubulars 4 to the wellhead center 22 to facilitate the pipe lowering operation.

Referring to fig. 3 to 5, in particular, the pipe handling robot 1 includes an upper support frame 12, a lower support frame 13, a column 11, a mounting frame 15, a gripping arm 17, and a posture adjustment driving member 16.

One end of the upright post 11 is rotatably connected with the upper support frame 12, and the other end of the upright post 11 is rotatably connected with the lower support frame 13. The upper support frame 12 is used for connecting with the derrick 2, and the lower support frame 13 is used for connecting with the derrick base 21. The upper support frame 12 is used for providing restraint and rotary guidance for the upright post 11, and the lower support frame 13 is mainly used for bearing the overturning moment of the upright post 11.

The mounting frame 15 is slidably connected to the upright 11 by a trolley 14. Specifically, the trolley 14 is slidably connected to the upright 11, and the mounting bracket 15 is fixedly connected to the trolley 14, so that when the trolley 14 slides along the upright 11, the mounting bracket 15 slides along the upright 11 together with the trolley 14.

The mounting frame 15 includes a base 151 and a horn assembly 152. The base 151 is attached to the trolley 14 and the amplitude variation assembly 152 is attached to the base 151. The horn assembly 152 is connected at one end to the base 151 and at the other end of the horn assembly 152 to the gripping arm 17 and the attitude adjustment drive 16. The amplitude variation assembly 152 is used for driving the clamping arm 17 and the attitude adjusting driving piece 16 to translate, so that the clamping arm 17 can move away from or close to the upright post 11.

In particular, the horn assembly 152 includes a first horn 1521, a second horn 1522, a web 1523, and a horn drive member 1524.

One end of the first amplitude transformer 1521 is hinged with the base 151, and the other end of the first amplitude transformer 1521 is hinged with the connecting plate 1523; one end of the second horn 1522 is hinged to the base 151, and the other end of the second horn 1522 is hinged to the link plate 1523. With the above structure, the first horn 1521, the second horn 1522, the link plate 1523, and the base 151 are connected to form a parallelogram structure. The first amplitude transformer 1521 serves as a driving rod in a parallelogram structure, the second amplitude transformer 1522 serves as a driven rod in the parallelogram structure, the connecting plate 1523 serves as a connecting rod for connecting the driving rod and the driven rod, and the base 151 serves as a frame, so that the second amplitude transformer 1522 can be driven to rotate together through rotation of the first amplitude transformer 1521, and the connecting plate 1523 can be driven to translate. The rotation of the first horn 1521 is driven by: one end of the amplitude variation driving member 1524 is hinged to the base 151, and the other end of the amplitude variation driving member 1524 is hinged to the first amplitude variation rod 1521, so that the amplitude variation driving member 1524, the base 151 and the first amplitude variation rod 1521 form an amplitude variation driving mechanism with a triangular structure, and one side formed by the amplitude variation driving member 1524 can be extended or shortened, so that the first amplitude variation rod 1521 is driven to rotate. Specifically, the variable amplitude drive 1524 is a hydraulic cylinder.

In other embodiments of the invention, it is also possible to have the first horn 1521 as a driven horn and the second horn 1522 as a driving horn. The amplitude variation driving component 1524 is hinged to the second amplitude variation rod 1522 and can drive the second amplitude variation rod 1522 to rotate, so that the connecting plate 1523 is driven to translate, and the first amplitude variation rod 1521 is driven to rotate.

The link plate 1523 also forms a triangular posture adjustment mechanism together with the posture adjustment driving member 16 and the clamp arm 17, and one side formed by the posture adjustment driving member 16 can be extended or shortened. Specifically, one end of the attitude adjusting driving member 16 is hinged to the connecting plate 1523, the other end of the attitude adjusting driving member 16 is hinged to the clamping arm 17, and the connecting plate 1523 is further hinged to the clamping arm 17. In this embodiment, the attitude adjustment actuator 16 is a hydraulic cylinder.

When the attitude adjustment drive 16 is extended or shortened, the clamp arm 17 is rotated accordingly. In this embodiment, the posture adjustment driving member 16 extends or shortens in the plane where the vertical direction is located, so as to drive the clamping arm 17 to rotate in the plane where the vertical direction is located, and thus the posture of the clamping arm 17 can be changed between the horizontal direction and the vertical direction.

In order to avoid the obstruction of the mounting frame 15 or the amplitude variation assembly 152 and the like to the posture adjustment of the clamping arm 17, a connecting lug 171 is arranged on the clamping arm 17, the connecting lug 171 is in a triangular structure, and the connecting point of the posture adjustment driving member 16 and the clamping arm 17 is positioned on the connecting lug 171; the connection point of the connecting plate 1523 and the clamping arm 17 is also located on the connecting projection 171, so that during the rotation of the clamping arm 17, the body of the clamping arm 17 and the mounting frame 15 or the amplitude variation assembly 152 and other structures can keep a gap, thereby avoiding interference.

One end of the holding arm 17 is provided with one holding portion 172, and the other end of the holding arm 17 is provided with the other holding portion 172. The clamping portion 172 has a clamping space for clamping the pipe 4.

When the amplitude variation driving component 1524 drives the first amplitude variation rod 1521 to rotate, the connecting plate 1523 can only translate along with the connecting plate 1523, so that if the length of the attitude adjusting driving component 16 is kept constant at this time, the attitude adjusting driving component 16 and the clamping arm 17 both translate along with the connecting plate 1523. When the first amplitude transformer 1521 rotates, one end of the first amplitude transformer 1521 far away from the base 151 moves in a direction close to or far away from the upright 11, and then the first amplitude transformer drives the clamping arm 17 to move in a direction far away from or close to the upright 11, so that the distance between the pipe 4 clamped by the clamping arm 17 and the upright 11 is adjusted.

Referring to fig. 6-9, the tube storage assembly 3 is adapted to be disposed below the tube handling robot 1 such that the tube 4 can be gripped from the tube storage assembly 3 when the gripper 172 of the tube handling robot 1 is proximate to the lower end of the column 11.

The pipe string storage assembly 3 includes a pipe string storage rack 301, a whipstock drive 37, a whipstock rod 36, a roll-over rack 38, and a roll-over drive 39.

Wherein the tube storage rack 301 includes a rack body 31 and a stopper 32. In the present embodiment, the frame body 31 has a hexahedral frame structure. The stopper 32 is connected to the frame 31.

In storing the pipe string 4, the support surface 35 is used for contacting the ground, the storage surface 34 faces upward, the number of the stoppers 32 is four, the tops of the four stoppers 32 are higher than the storage surface 34, a storage space 33 is formed between the four stoppers 32, and the pipe string 4 can be placed in the storage space 33.

A whipstock drive 37 is connected to the whipstock 36 for providing different directional inclinations on the storage surface 34 to enable the pipe 4 on the storage surface 34 to be rotated in a predetermined direction. Specifically, a whipstock drive 37 and a whipstock 36 are attached to one tube storage rack 301. A whipstock drive member 37 is hingedly connected to the whipstock rod 36.

The side of whipstock driving piece 37 one end through installation otic placode and support body 31 is articulated to be connected with, and the whipstock driving piece 37 other end is articulated with 36 one end of whipstock, and the whipstock 36 other end is articulated with support body 31. The whipstock driving member 37, the whipstock 36 and the frame body 31 form a triangular structure, wherein the length of one side formed by the whipstock driving member 37 can be extended or shortened. Specifically, in the present embodiment, the whipstock drive 37 is selected to be a cylinder.

The storage surface 34 has first and second oppositely disposed ends. The whipstock 36 has a first operative position and a second operative position. With the monument rod 36 in the first working position, the first end of the storage surface 34 is spaced further from the support surface 35 than the second end of the storage surface 34 is spaced from the support surface 35; when the monument rod 36 is in the second working position, the first end of the storage surface 34 is spaced from the support surface 35 by a distance that is less than the distance that the second end of the storage surface 34 is spaced from the support surface 35.

The tumble driving member 39, the tumble frame 38 and the frame body 31 form a triangular structure, and one side constituted by the tumble driving member 39 can be extended or shortened. Specifically, the tumble drive 39 is provided as a cylinder.

The roll-over stand 38 has a holding surface, and specifically, the holding surface includes a first bent portion 381 and a second bent portion 382. When the turnover driving member 39 is shortened, the first bent portion 381 is lower than the storage surface 34, and the second bent portion 382 is higher than the storage surface 34, so that a space for accommodating a single pipe tool 4 is formed between the second bent portion 382 and the abutting block 32 at one end, so as to clamp the pipe tool 4 to be grabbed or just put down, and the remaining pipe tools 4 are accommodated between the second bent portion 382 and the abutting block 32 at the other end. When the roll-over drive 39 is extended and the roll-over stand 38 is rotated, the tube 4 which has just been lowered can roll towards the lower end of the storage surface 34 until the first bend 381 is above the storage surface 34 and the second bend 382 is below the storage surface 34.

Through the cooperation of the turning driving part 39, the turning frame 38, the whipstock driving part 37 and the whipstock 36, the pipe tool 4 can be moved to a preset direction, so that the pipe tool 4 can be conveniently grabbed, put down and stored.
