Description

Technical Field

[0001] This invention relates to the field of drilling technology, and in particular to a drilling string delivery device and delivery method. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] A tubing string is a steel pipe assembly used in oil drilling rigs or geological drilling rigs to transmit rotary power, mud, and carry out drilling operations. In order to meet different drilling depths, the tubing strings used by drilling rigs need to have the function of splicing and assembling.

[0004] Currently, the connection between tubing strings is usually achieved through threaded connections. One end of the tubing string is equipped with a threaded connector, and the other end is equipped with a threaded groove that matches the threaded connector. Before drilling operations, a large number of tubing strings are stacked near the drilling point. After the drilling rig is moved into position, the lifting device on the drilling rig is used to connect to the threaded end of the tubing string. Then, the lifting device is retrieved, and the flat-lying tubing string is gradually moved from a horizontal state to a vertical state during the pulling process. After that, the subsequent tubing string splicing operation can be carried out.

[0005] However, during the process of the tubing being pulled by the lifting device, the side with the threaded connector will rub and move on the ground. Long-term repeated operation will inevitably lead to wear at the threads, affecting the connection strength and sealing performance between the tubing. Therefore, in order to ensure the safety, efficiency and cost-effectiveness of drilling operations, a drilling tubing transport device is proposed to transport the tubing to reduce wear at the tubing threads. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned shortcomings by providing a drilling tubing delivery device and method that reduces wear at threaded connections during tubing installation.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a drilling tubing delivery device, comprising:

[0008] Tube storage mechanism for storing tubes in layers and stacks;

[0009] The tubing pusher mechanism is located on top of the tubing storage mechanism. It is used to push the tubing within the pushing area of ​​the tubing pusher mechanism along its axial direction and can rotate and move together with the tubing threaded connector.

[0010] A transfer mechanism is used to transfer tubing between the tubing storage mechanism and the pushing area of ​​the tubing pushing mechanism;

[0011] The flipping platform is used to receive the tubing pushed out by the tubing pushing mechanism and to continue pushing the tubing in conjunction with the tubing pushing mechanism.

[0012] Furthermore, the tubing storage mechanism includes at least one storage area, which consists of a U-shaped frame and multiple shelves located within the U-shaped frame. The multiple shelves are staggered on both sides of the U-shaped frame, and a serpentine channel for the tubing to move up and down is formed between the multiple shelves and the U-shaped frame. The tubing pushing mechanism is located at the top exit of the serpentine channel.

[0013] Furthermore, the shelf includes a fixed plate connected to the U-shaped frame. A rotating plate is rotatably mounted on the side of the fixed plate away from the U-shaped frame via a torsion spring. When the torsion spring is in its natural state, the rotating plate abuts against the adjacent fixed plate at the bottom. A telescopically movable pushing assembly is provided at the bottom of the fixed plate. When the pushing assembly is in its retracted state, it does not contact the rotating plate. When the pushing assembly is in its extended state, it pushes the rotating plate to rotate until it is flush with the fixed plate. The distance between the rotating plate and the side wall of the adjacent U-shaped frame is not less than the outer diameter of the column, which is used to allow the column to move from the upper shelf to the lower shelf.

[0014] Furthermore, there are two storage areas, and the top fixing plates corresponding to the two storage areas are connected. A first sinking trough is provided between the two top fixing plates, and the tube column pushing mechanism is located in the first sinking trough.

[0015] Furthermore, the tube column pushing mechanism includes a first rack disposed in the first settling trough and two slide plates slidably disposed in the first settling trough. The top of the slide plate is flush with the top fixed plate. The slide plate is provided with a driving component that drives the slide plate to move along the length direction of the first settling trough. A first push plate and a flipping motor that drives the first push plate to flip are rotatably disposed on the slide plate away from the flipping platform. The first push plate is provided with a positioning pin inserted into the tube column. A second push plate is fixedly disposed on the slide plate close to the flipping platform.

[0016] The drive assembly includes a travel motor embedded in the slide plate, and at least two gears meshing with the first rack are provided in the slide plate. The output end of the travel motor is provided with a chain and sprocket assembly for driving multiple gears to rotate synchronously.

[0017] Furthermore, the flipping platform includes a receiving plate of the same height as the top fixed plate and multiple support legs disposed at the bottom of the receiving plate. The top of the receiving plate is provided with a second sink groove for the slide to travel. A second rack that meshes with a gear is disposed in the second sink groove. The top of the receiving plate is provided with two side baffles located on both sides of the width direction of the second sink groove. The side baffles are used to guide the movement of the tubular column.

[0018] The drive assembly can move the slide plate from the first sink to the second sink.

[0019] Furthermore, the transfer mechanism includes two telescopic components disposed on the two side walls of the U-shaped frame. Each of the two telescopic components has a connecting rod at its top end. Each connecting rod has an electric slide at both ends. Each electric slide has two levers that move between the two side walls of the U-shaped frame under the drive of the electric slide. The U-shaped frame is located between the levers corresponding to the two electric slides, and the column is located within the movement area of ​​the levers. One of the levers moves between the receiving plate and the U-shaped frame.

[0020] A drilling string delivery method, comprising any one of the drilling string delivery devices described in any one of the claims, wherein the method is as follows:

[0021] S1. Hoist this device to the vicinity of the drilling rig according to the location of the drilling rig on site, and make the side of the tilting platform away from the pipe storage mechanism as close to the drilling rig as possible;

[0022] S2. After the hoisting operation is completed, the operator first controls the telescopic component and the electric slide to adjust the position of the lever, so that the lever moves to one of the storage areas where the pipe column is stored in advance, and the pipe column to be transferred is placed between two adjacent levers.

[0023] S3. After the adjustment is completed, the operator will once again operate the telescopic component and the electric slide to adjust the position of the lever, so that the lever pushes the tube column upward along the serpentine channel until the tube column is transferred into the pushing area of ​​the tube column pushing mechanism.

[0024] S4. After the tube column is transferred to the position, start the motor in the tube column pushing mechanism to make multiple gears rotate synchronously under the drive of the chain and sprocket components. Utilize the meshing relationship between the gears and the first and second racks to make the slide plate equipped with gears push the tube column in the pushing area to the flipping platform.

[0025] S5. After the transfer is completed, connect the hoisting device of the drilling rig to the end of the pipe with the threaded groove, and then slowly pull the hoisting device to make one end of the pipe lift up and the other end gradually approach the drilling rig. During this process, the sliding plate and the positioning pin on it continue to move with the pipe, and the first push plate is slowly rotated by the rotating motor to keep the end of the pipe away from the hoisting device of the drilling rig relatively stationary with the sliding plate until the pipe is close to the vertical state and separates from the positioning pin.

[0026] S6. After the tubing is lifted, repeat the above S2-S5 operations to continuously transport the tubing to the drilling rig.

[0027] S7. When the tubing is removed from the drilling rig, S5 and S4 are reversed to transfer the tubing from the drilling rig to the top exit of the serpentine channel. Then, the jacking assembly is operated to push the rotating plate to rotate until it is flush with the fixed plate. Then, S3 is reversed to move the tubing to the storage area for storage.

[0028] The beneficial effects of this invention are reflected in:

[0029] This invention utilizes a transfer mechanism to transfer a single pipe stored in a pipe storage mechanism to the pushing area of ​​a pipe pushing mechanism. The pipe pushing mechanism then pushes the pipe onto a tilting platform. After the hoisting device of the drilling rig connects to one end of the pipe thread groove on the tilting platform, the hoisting device is retrieved, causing the horizontally placed pipe to gradually move from a horizontal to a vertical position during the pulling process. During this process, the pipe pushing mechanism moves and tilts along with the pipe threaded connector, keeping the pipe pushing mechanism and the pipe threaded connector relatively stationary, thereby reducing wear at the threaded connection during pipe tilting.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figure 1-6 This invention discloses a drilling string delivery device, comprising:

[0043] Tube storage mechanism 1 is used for storing tubes in layers and stacks.

[0044] The tubing pusher 2 is located on top of the tubing storage mechanism 1 and is used to push the tubing within the pushing area of ​​the tubing pusher 2 along its axial direction, and can rotate and move together with the tubing threaded connector.

[0045] The transfer mechanism 3 is used to transfer the tubing between the tubing storage mechanism 1 and the pushing area of ​​the tubing pushing mechanism 2;

[0046] The flipping platform 4 is used to receive the tube pushed out by the tube pusher mechanism 2 and to continue pushing the tube in cooperation with the tube pusher mechanism 2.

[0047] In this invention, the tubing to be installed is pre-moved to the tubing storage mechanism 1 and stacked in layers. When the drilling rig needs to splice the tubing, the transfer mechanism 3 transfers the single tubing stored in the tubing storage mechanism 1 to the pushing area of ​​the tubing pushing mechanism 2. Then, the tubing pushing mechanism 2 pushes the tubing onto the tilting platform 4. After the lifting device of the drilling rig is connected to one end of the threaded groove of the tubing on the tilting platform 4, the lifting device is retrieved, so that the flat-lying tubing gradually moves from a horizontal state to a vertical state during the pulling process. During this process, the tubing pushing mechanism 2 moves and tilts along with the threaded connector of the tubing, so that the tubing pushing mechanism 2 and the threaded connector of the tubing are relatively stationary, thereby reducing the wear at the threaded connection when the tubing is tilted.

[0048] In one embodiment, the tube storage mechanism 1 includes at least one storage area, which consists of a U-shaped frame 11 and a plurality of shelves 12 located within the U-shaped frame 11. The plurality of shelves 12 are staggered on both sides of the U-shaped frame 11, and a serpentine channel for the tube to move up and down is formed between the plurality of shelves 12 and the U-shaped frame 11. The tube pushing mechanism 2 is located at the top outlet of the serpentine channel.

[0049] This design makes full use of the vertical space of the site by placing multiple pipe columns one by one in the serpentine channel. When the transfer mechanism 3 retrieves the pipe columns, the pipe columns can be moved one by one to the top exit of the serpentine channel, which facilitates the pipe column pushing mechanism 2 to push the pipe columns.

[0050] In one embodiment, the shelf 12 includes a fixed plate 121 connected to the U-shaped frame 11. A rotating plate 122 is rotatably disposed on the side of the fixed plate 121 away from the U-shaped frame 11 via a torsion spring. When the torsion spring is in its natural state, the rotating plate 122 abuts against the bottom adjacent fixed plate 121. A push assembly 123 capable of telescopic movement is disposed at the bottom of the fixed plate 121. When the push assembly 123 is in a retracted state, the push assembly 123 does not contact the rotating plate 122. When the push assembly 123 is in an extended state, the push assembly 123 pushes the rotating plate 122 to rotate until it is flush with the fixed plate 121. The distance between the rotating plate 122 and the side wall of the adjacent U-shaped frame 11 is not less than the outer diameter of the column, which is used to allow the column to move from the upper shelf 12 to the lower shelf 12.

[0051] With this design, when the tubing moves upward along the serpentine channel, the upper rotating plate 122 is first pushed upward to flip, allowing the tubing to move past the rotating plate 122 to the corner of the serpentine channel. Then, the rotating plate 122 is reset under the action of the torsion spring, so that the rotating plate 122 abuts against the bottom adjacent fixed plate 121, providing a channel for the lower tubing to move upward, so that it can roll to the upper fixed plate 121 through the rotating plate 122. By repeating the above operation, it can gradually move to the top exit of the serpentine channel. When the tubing needs to be placed into the serpentine channel for stacking, the push assembly 123 is activated, so that the push assembly 123 is in an extended state, pushing each rotating plate 122 to rotate to be flush with the fixed plate 121, so that the downward movement of the tubing is not blocked by the rotating plate 122, so that it can roll downward along the serpentine channel to complete the stacking of multiple tubing.

[0052] In practice, to ensure that the rotating plate 122 can work properly, the tubing must be stacked out of the area where the rotating plate 122 rotates downward.

[0053] Preferably, the pushing assembly 123 can be a hydraulic telescopic component, a pneumatic telescopic component, or an electric telescopic component, all of which are mature existing technologies and will not be elaborated further here.

[0054] In one embodiment, there are two storage areas, and the top fixing plates 121 corresponding to the two storage areas are connected. A first sinking groove is provided between the two top fixing plates 121, and the tube column pushing mechanism 2 is disposed in the first sinking groove.

[0055] This design allows the tubing removed from the drilling rig to be stored separately in two storage areas from the tubing that has not yet been installed on the drilling rig, making it easier for subsequent staff to maintain and repair the removed tubing.

[0056] In one embodiment, the tube column pushing mechanism 2 includes a first rack 21 disposed in the first sinking groove and two slide plates 22 slidably disposed in the first sinking groove. The top of the slide plates 22 is flush with the top fixing plate 121. A driving component 23 is disposed in the slide plate 22 to drive the slide plate 22 to move along the length direction of the first sinking groove. A first push plate 24 and a flipping motor for driving the first push plate 24 to flip are rotatably disposed on the slide plate 22 away from the flipping platform 4. A positioning pin 25 inserted into the tube column is disposed on the first push plate 24. A second push plate 26 is fixedly disposed on the slide plate 22 close to the flipping platform 4.

[0057] The drive assembly 23 includes a travel motor embedded in the slide plate 22. The slide plate 22 is provided with at least two gears that mesh with the first rack 21. The output end of the travel motor is provided with a chain and sprocket assembly for driving multiple gears to rotate synchronously.

[0058] This design allows the slide plate 22 to move along the first groove under the cooperation of the drive assembly 23 and the first rack 21. When the tube column to be moved is transferred between the first push plate 24 and the second push plate 26, the tube column can be transferred between the tube column storage mechanism 1 and the flipping platform 4 by changing the travel direction of the two slide plates 22. Since the first push plate 24 is rotatably mounted on the slide plate 22 and can be driven by the flipping motor to change direction, the first push plate 24 can move with the tube column when the tube column is flipped after the positioning pin 25 is inserted into the threaded connector of the tube column, thereby reducing the wear of the threaded connector of the tube column.

[0059] It should be noted that chain and sprocket components are common knowledge in this field, so their specific structural composition and working principle will not be elaborated on in this article.

[0060] In one embodiment, the flipping platform 4 includes a receiving plate 41 at the same height as the top fixed plate 121 and a plurality of support legs 42 disposed at the bottom of the receiving plate 41. The top of the receiving plate 41 is provided with a second sink groove for the sliding plate 22 to travel in. A second rack 43 that meshes with a gear is disposed in the second sink groove. The top of the receiving plate 41 is provided with two side baffles 44 located on both sides of the width direction of the second sink groove. The side baffles 44 are used to guide the movement of the tubing column.

[0061] The drive component 23 can move the slide plate 22 from the first sink to the second sink.

[0062] This design allows the slide plate 22 to continue moving within the second sink after it has been transferred from the first sink to the second sink, with the cooperation of the drive assembly 23 and the second rack 43.

[0063] In one embodiment, the transfer mechanism 3 includes two telescopic components 31 disposed on the two side walls of the U-shaped frame 11. Each of the two telescopic components 31 is provided with a connecting rod 32 at its top end. Each end of the connecting rod 32 is provided with an electric slide table 33. The electric slide table 33 is provided with two levers 34 that are driven by the electric slide table 33 and move between the two side walls of the U-shaped frame 11. The U-shaped frame 11 is located between the levers 34 corresponding to the two electric slide tables 33, and the column is located within the moving area of ​​the levers 34. One of the levers 34 moves between the receiving plate 41 and the U-shaped frame 11.

[0064] This design, through the telescopic movement of the telescopic component 31 and the horizontal movement of the electric slide 33, drives the two levers 34 on the same side to move to both sides of the tube column to be transported. This allows the tube column to move between the two side walls of the U-shaped frame 11 by the levers 34. At the same time, due to the restriction of the serpentine channel during the movement, the tube column can be transferred between the pushing areas of the tube column storage mechanism 1 and the tube column pushing mechanism 2. Furthermore, because the tube column is regularly placed in the serpentine channel, the transfer mechanism 3 can pick up and put down the tube column according to the placement pattern.

[0065] Preferably, the telescopic component 31 can be a hydraulic telescopic component, a pneumatic telescopic component, or an electric telescopic component, all of which are mature existing technologies and will not be elaborated further here.

[0066] A drilling string delivery method, comprising any one of the following drilling string delivery devices, wherein the method is as follows:

[0067] S1. Hoist this device to the vicinity of the drilling rig according to the location of the drilling rig on site, and make the side of the tilting platform 4 away from the pipe storage mechanism 1 as close to the drilling rig as possible;

[0068] S2. After the hoisting operation is completed, the operator first controls the telescopic component 31 and the electric slide table 33 to adjust the position of the lever 34, so that the lever 34 moves to one of the storage areas where the pipe column is stored in advance, and the pipe column to be transferred is placed between two adjacent levers 34.

[0069] S3. After the adjustment is completed, the operator once again manipulates the telescopic component 31 and the electric slide table 33 to adjust the position of the lever 34, so that the lever 34 pushes the tube column upward along the serpentine channel until the tube column is transferred to the pushing area of ​​the tube column pushing mechanism 2.

[0070] S4. After the tube column is transferred to the position, the motor in the tube column pushing mechanism 2 is started, so that multiple gears rotate synchronously under the drive of the chain and sprocket components. By utilizing the meshing relationship between the gears and the first rack 21 and the second rack 43, the slide plate 22 equipped with gears pushes the tube column in the pushing area to the flipping platform 4.

[0071] S5. After the transfer is completed, the hoisting device of the drilling rig is connected to the end of the pipe with the threaded groove. Then the hoisting device is slowly stretched to make one end of the pipe lift up and the other end gradually approach the drilling rig. During this process, the sliding plate 22 and the positioning pin 25 on it continue to move with the pipe. The first push plate 24 is slowly rotated by the rotating motor to keep the end of the pipe away from the hoisting device of the drilling rig relatively stationary with the sliding plate 22 until the pipe is close to the vertical state and separates from the positioning pin 25.

[0072] S6. After the tubing is lifted, repeat the above S2-S5 operations to continuously transport the tubing to the drilling rig.

[0073] S7. When the tubing is removed from the drilling rig, S5 and S4 are reversed to transfer the tubing from the drilling rig to the top exit of the serpentine channel. Then, the jacking assembly 123 is operated to push the rotating plate 122 to rotate until it is flush with the fixed plate 121. Then, S3 is reversed to move the tubing to the storage area for storage.

[0074] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0075] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0076] Additionally, "multiple" refers to two or more.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

S5. After the transfer is completed, the hoisting device of the drilling rig is connected to the end of the pipe with the threaded groove. Then the hoisting device is slowly stretched so that one end of the pipe is raised and the other end gradually approaches the drilling rig. During this process, the sliding plate (22) and the positioning pin (25) on it continue to move with the pipe. The first push plate (24) is driven by the flipping motor to slowly flip so that the end of the pipe away from the hoisting device of the drilling rig remains relatively stationary with the sliding plate (22) until the pipe is close to the vertical state and separates from the positioning pin (25). S6. After the tubing is lifted, repeat the above S2-S5 operations to continuously transport the tubing to the drilling rig. S7. When the tubing is removed from the drilling rig, the S5 and S4 operations are reversed to transfer the tubing from the drilling rig to the top exit of the serpentine channel. Then, the jacking assembly (123) is operated to push the rotating plate (122) to rotate until it is flush with the fixed plate (121). Then, the S3 operation is reversed to move the tubing to the storage area for storage.
