[0002] This application claims priority to Chinese patent application No. 202311856828.2 filed on December 29, 2023, and cites the contents disclosed in the above patent application as part of this application. Technical Field

[0003] The present disclosure relates to the technical field of oil drilling and development, and in particular to a side storage type pipe string conveying device. Background Art

[0004] On existing land-based oil drilling rigs, powered catwalks have gradually replaced conventional catwalks, and their use is becoming increasingly common. Powered catwalks transport tubing in both directions between the storage area and the drill floor. This automated system requires no human intervention, significantly reducing the workload and operational hazards for drillers. However, existing powered catwalks can only transport one tubing string (drill pipe, drill collars, casing, etc.) per cycle, resulting in relatively low operational efficiency. This drawback of single catwalks is becoming increasingly prominent, particularly with the exploration and development demands of deep and ultra-deep wells and the development of tubing automation systems.

[0005] To address the low efficiency of existing power catwalks, existing technologies have introduced power catwalks that can transport three drill pipes at a time. However, this type of catwalk can only transport one or three drill pipes. Separating two, four, or even more pipe strings is difficult. This is especially true for deep and ultra-deep wells, where four single columns are required. Power catwalks that can transport three pipes at a time are no longer sufficient.

[0006] In view of this, the inventor has designed a side storage type tubular column conveying device based on many years of production and design experience in this field and related fields and after repeated experiments, in order to solve the problems existing in the prior art. Summary of the Invention

[0007] The purpose of the present disclosure is to provide a side storage type pipe string conveying device, which can effectively improve the conveying efficiency of the power catwalk.

[0008] To achieve the above objectives, the present disclosure provides a side-storage type tubular string conveying device, wherein the side-storage type tubular string conveying device includes:

[0009] The drill string delivery frame is provided with a transport chute for transporting the drill string;

[0010] A transport pulley is provided in the transport chute and can push the pipe string to move back and forth along the length direction of the transport chute;

[0011] At least one storage module is arranged on the drill string frame and located on the outside of the transport chute. The storage module includes a storage mechanism, a loading mechanism and a kick-out mechanism arranged on the drill string frame. The storage mechanism is used to store the pipe string; the loading mechanism can move the pipe string stored in the storage mechanism into the transport chute; the kick-out mechanism can move the pipe string in the transport chute into the storage mechanism.

[0012] Compared with the prior art, the embodiments of the present disclosure have the following features and advantages:

[0013] The side-storage type pipe string conveying device proposed in the embodiment of the present disclosure has a storage module installed on the drill string frame, which can accommodate multiple pipe strings. When the side-storage type pipe string conveying device is used for a power catwalk, the power catwalk can convey multiple pipe strings to the drilling platform in one operating cycle, effectively improving the pipe string conveying efficiency of the power catwalk.

[0031] The details of the present disclosure can be more clearly understood in conjunction with the accompanying drawings and the description of the specific embodiments of the present disclosure. However, the specific embodiments of the present disclosure described herein are only for the purpose of explaining the present disclosure and should not be understood as limiting the present disclosure in any way. Based on the teachings of the present disclosure, skilled artisans can conceive of any possible variations based on the present disclosure, which should be considered to fall within the scope of the present disclosure.

[0032] As shown in Figures 1 to 12, an embodiment of the present disclosure proposes a side-storage type pipe string conveying device 100, which includes a drill string frame 1, a transport pulley 2 and at least one storage module. The drill string frame 1 is provided with a transport chute for transporting pipe strings; the transport pulley 2 is arranged in the transport chute and can push the pipe string to move along the length direction of the transport chute; the storage module is arranged on the drill string frame 1 and is located on one side of the transport chute. The storage module includes a storage mechanism 3, a loading mechanism 5 and a kick-out mechanism 6 arranged on the drill string frame 1. The storage mechanism 3 is used to store pipe strings; the loading mechanism 5 can move the pipe strings stored in the storage mechanism 3 into the transport chute; the kick-out mechanism 6 can move the pipe strings in the transport chute into the storage mechanism 3.

[0033] The side storage type pipe string conveying device 100 proposed in the embodiment of the present disclosure has a storage module installed on the drill string frame 1, which can accommodate multiple pipe strings. When the side storage type pipe string conveying device 100 is used for a power catwalk, the power catwalk can convey multiple pipe strings to the drilling platform in one operating cycle, effectively improving the pipe string conveying efficiency of the power catwalk.

[0034] The side storage type pipe conveying device 100 proposed in the embodiment of the present disclosure has a storage module arranged on the side of the drill string frame 1, which does not affect the connection between the two ends of the drill string frame 1 and the power catwalk. It can be applied to power catwalks of different structural forms, and thus can be applied to the use requirements of different drilling rigs, and has strong adaptability.

[0035] The side storage type tubing conveying device 100 proposed in the embodiment of the present disclosure changes the traditional method of conveying one tubing at a time, reduces the number of tubing conveyances, and thereby solves the problem of low efficiency of power catwalk conveyance in existing land drilling rigs, especially deep well and ultra-deep well drilling rigs, and untimely delivery of tubing during coordinated operations.

[0036] The side-storage pipe string conveying device 100 proposed in the embodiment of the present disclosure improves the pipe string conveying efficiency of the power catwalk, thereby greatly reducing the number of catwalk lifting times, and is energy-efficient and highly efficient.

[0037] The side storage type pipe string conveying device 100 proposed in the embodiment of the present disclosure can adjust the number of conveying pipe strings according to the on-site working conditions, and can handle 1, 2, 3, 4 or other numbers of pipe strings, which is flexible and convenient.

[0038] In an optional embodiment of the present disclosure, the side-storage type tubular string conveying device 100 includes two storage modules, which are respectively located on both sides of the transport chute, further increasing the number of tubular strings that the side-storage type tubular string conveying device 100 can accommodate and improving the tubular string conveying efficiency of the power catwalk.

[0039] In an optional embodiment of the present disclosure, as shown in Figures 3a and 3b, the storage mechanism 3 includes at least two storage assemblies, which are spaced apart along the length of the drill string frame 1. Each storage assembly includes a storage arm 31, a storage arm cylinder 32, a baffle 33, and a baffle cylinder 34. One end of the storage arm 31 is hinged to the drill string frame 1, and the storage arm 31 forms an angle with the transport chute. One end of the storage arm cylinder 32 is hinged to the drill string frame 1, and the other end of the storage arm cylinder 32 is hinged to the storage arm 31. The storage arm cylinder 32 can push the storage arm 31 to swing up and down. The baffle 33 is hinged to the other end of the storage arm 31. One end of the baffle cylinder 34 is hinged to the storage arm 31, and the other end of the baffle 33 is hinged to the baffle 33. The baffle cylinder 34 can push the baffle 33 to swing around the storage arm 31. With the above structure, when the storage arm cylinder 32 is extended or retracted, the storage arm 31 can swing up and down under the action of the storage arm cylinder 32. When delivering the drill (that is, when the pipe string is rolled from the pipe rack to the storage mechanism 3), the storage arm 31 tilts inward, and when throwing the drill (that is, when the pipe string is rolled from the storage mechanism 3 to the pipe rack), the storage arm 31 tilts outward; the baffle 33 is installed on the outside of the storage arm 31, and the baffle 33 can be rotated around the storage arm 31 under the action of the baffle cylinder 34 to flatten or erect the baffle 33. After the baffle 33 is flattened, it is used as a transition plate when the pipe string rolls from the pipe rack to the storage arm 31. At the same time, when the pipe string enters the storage arm 31, the baffle 33 is erected to play a safety protection role to prevent the pipe string from accidentally falling off.

[0040] In an optional example of this embodiment, the length of the storage arm 31 is determined by the outer diameter and number of tubular columns expected to be stored.

[0041] Furthermore, the storage mechanism 3 can store 1, 2 or more pipe strings.

[0042] In this embodiment, the storage mechanism 3 may also include three or more storage assemblies. The number of storage assemblies is determined according to the length of the drill string frame and is sufficient to ensure stability within the pipe string storage mechanism 3. Furthermore, the storage arm cylinders 32 of the multiple storage assemblies are configured to operate synchronously.

[0043] In an optional example of this embodiment, the storage module further includes an adjustment platform 4, which is arranged at one end of the drill string frame 1. The adjustment platform 4 includes an adjustment pulley 41, a platform frame 42, an adjustment cylinder 43, a first connecting seat 44, and a second connecting seat 46. The first connecting seat 44, the platform frame 42, and the second connecting seat 46 are connected in sequence. The platform frame 42 is arranged parallel to the drill string frame 1. The first connecting seat 44 and the second connecting seat 46 are respectively connected to the drill string frame 1. The upper surface of the platform frame 42 is an adjustment plane for receiving the pipe string. The adjustment pulley 41 is installed on the platform frame 42 and slides with the adjustment plane. The adjustment cylinder 43 is installed on the lower surface of the platform frame 42 and pushes the adjustment pulley 41 to move back and forth along the length direction of the platform frame 42. The adjustment platform 4 is used to adjust the position of the pipe string in the length direction of the drill string frame 1 in the storage mechanism 3. Specifically, the swing cylinder 45 and the storage arm cylinder 32 are set synchronously, thereby ensuring that the adjustment plane of the platform frame 42 and the upper surface of the storage arm 31 are always in the same plane. In this way, the pipe string rolled onto the storage arm 31 also rolls onto the adjustment plane at the same time, and the adjustment cylinder 43 drives the adjustment pulley 41 to press against the end of the pipe string, and the adjustment pulley 41 can effectively prevent the pipe string from sliding down; at the same time, the adjustment pulley 41 can also drive the pipe string to move back and forth along the length direction of the drill string frame 1 to adjust the position of the pipe string, ensure the distance between the pipe string and the transport pulley 2, and reduce the impact of the pipe string sliding down on the transport pulley 2.

[0044] In an optional example of this embodiment, a position sensor is provided on the adjusting cylinder 43 so that the adjusting cylinder 43 can be extended and retracted according to a value set in a program, thereby accurately controlling the pipe string at an appropriate position.

[0045] In an optional example of this embodiment, the adjustment platform 4 is provided at the rear end of the drill string frame 1 .

[0046] In an optional example of this embodiment, the storage module further includes a swing cylinder 45, a first connecting seat 44, and a second connecting seat 46, respectively, hinged to the drill string frame 1. One end of the swing cylinder 45 is hinged to the drill string frame 1, and the other end of the swing cylinder 45 is hinged to the platform frame 42. The swing cylinder 45 propels the platform frame 42 to swing up and down. The swing cylinder 45 and the storage arm cylinder 32 are synchronously arranged to ensure that the adjustment plane of the platform frame 42 and the upper surface of the storage arm 31 are always in the same plane.

[0047] In another optional example of this embodiment, the first connecting seat 44 and the second connecting seat 46 are fixedly connected to the drill string frame 1. The adjustment platform 4 is fixed and does not need to swing up and down synchronously with the storage mechanism.

[0048] In another optional embodiment of the present disclosure, the adjustment platform 4 includes an adjustment pulley 41, a platform frame 42, an adjustment cylinder 43, a first connecting seat 44, and a swing cylinder 45. The platform frame 42 is arranged parallel to the drill string frame 1. The two ends of the platform frame 42 are respectively connected to the first connecting seat 44 and the storage arm 31. The first connecting seat 44 is hinged to the drill string frame 1. The adjustment pulley 41 is mounted on the platform frame 42 and slides with the platform frame 42. The adjustment cylinder 43 is mounted on the platform frame 42 and pushes the adjustment pulley 41 to move back and forth along the length direction of the platform frame 42. One end of the swing cylinder 45 is hinged to the drill string frame 1, and the other end of the swing cylinder 45 is hinged to the platform frame 42. The swing cylinder 45 pushes the platform frame 42 to swing up and down. Compared with the previous embodiment, this embodiment replaces the second connecting seat 46 with the storage arm 31, reducing the number of mechanisms.

[0049] In an optional embodiment of the present disclosure, as shown in Figures 5a and 5b, the loading mechanism 5 includes a loading plate 51 and a loading cylinder 52. A first notch that aligns with the loading plate 51 is opened on an inner side wall of the transport chute, and the loading plate 51 is installed at the first notch. One side of the loading plate 51 has an unloading surface B, a loading surface A and an end surface C arranged in sequence from the inside to the outside. The unloading surface B is planar and flush with the inner side wall of the transport chute. The loading surface A is also planar and has an angle with the unloading surface B. The end surface C is an arc surface. The loading surface A and the end surface C protrude from the transport chute. The middle part of the other side of the loading plate 51 is hinged to the drill string frame 1. One end of the loading cylinder 52 is hinged to the drill string frame 1, and the other end of the loading cylinder 52 is hinged to the loading plate 51. The loading cylinder 52 pushes the loading plate 51 to rotate around the drill string frame 1. When the loading cylinder 52 is extended or retracted, the loading plate 51 can swing inward or outward. One side of the loading plate 51 is a special-shaped structure. When the loading mechanism 5 is in the unloading state, the unloading surface B of the loading plate 51 is flush with the inner wall of the transport chute. When the loading mechanism 5 is loading, the loading surface A of the loading plate 51 hooks a single pipe string into the loading surface A and the unloading surface B, and the end surface C blocks the next pipe string outside the loading plate 51, ensuring that only one pipe string is loaded into the transport chute at a time.

[0050] In an optional embodiment of the present disclosure, as shown in Figures 6a and 6b, the kick-out mechanism 6 includes a kick-out plate 61 and a kick-out cylinder 62. A second notch that aligns with the kick-out plate 61 is provided on an inner side wall of the transport chute, and the kick-out plate 61 is installed in the second notch. One end of the kick-out plate 61 has a kick-out surface flush with the inner side wall, and the other end of the kick-out plate 61 is hinged to the drill string frame 1. One end of the kick-out cylinder 62 is hinged to the drill string frame 1, and the other end of the kick-out cylinder 62 is hinged to the kick-out plate 61. The kick-out cylinder 62 pushes the swinging kick-out plate 61 to rotate around the drill string frame 1. When the kick-out cylinder 62 extends or retracts, the kick-out plate 61 can extend or retract. When the kick-out plate 61 extends, the pipe string is kicked out from the middle position of the transport chute of the drill string frame 1 to the side of the transport chute to unload the pipe string into the storage mechanism 3.

[0051] In an optional example of this embodiment, the kick-out plate 61 is composed of a crank 611 and a flat plate 612. The flat plate 612 is mounted at one end of the crank 611, with the surface of the flat plate 612 facing away from the crank 611 forming the kick-out surface. The other end of the crank 611 is hinged to the drill string frame 1, and the middle portion of the crank 611 is hinged to the kick-out cylinder 62. The transport chute of the drill string frame 1 is provided with a second notch at the kick-out mechanism 6 to avoid the kick-out plate 61. When the kick-out cylinder 62 is retracted to its shortest position, the flat plate 612 is flush with the inner wall (i.e., the upper surface) of the transport chute.

[0052] In an optional example of this embodiment, the loading mechanism 5 cooperates with the kicking mechanism 6 to flip the pipe string out of the transport chute of the drill string delivery frame 1 .

[0053] In an optional embodiment of the present disclosure, the transport chute is V-shaped, and a chain (or wire rope), a pulley drive wheel 7, a passive sprocket 8 and a driving mechanism are installed on the drill string frame 1. The two ends of the transport pulley 2 are respectively connected to the two ends of the chain, and the pulley drive wheel 7 and the passive sprocket 8 can be rotatably installed on the two ends of the drill string frame 1. The chain is centrally arranged in the drill string frame 1 and tensioned on the pulley drive wheel 7 and the passive sprocket 8. The driving mechanism can drive the pulley drive wheel 7 to rotate, and the pulley drive wheel 7 pulls the transport pulley 2 forward and backward along the length direction of the transport chute through the chain.

[0054] In an optional example of this embodiment, the driving mechanism may be a hydraulic motor or an electric motor driving mechanism.

[0055] In an optional example of this embodiment, a guide mechanism is provided between the transport chute and the transport pulley 2, which further ensures that the transport pulley 2 moves smoothly along the length direction of the transport chute.

[0056] In an optional example, the guide mechanism includes a guide block and a guide slideway, and the guide block and the guide sleeve are respectively installed on the transport pulley 2 and the drill string frame 1.

[0057] In an optional embodiment of the present disclosure, the side-storage type pipe string conveying device 100 can be matched with power catwalks of various structural forms such as a lifting type power catwalk and a wire rope lifting type power catwalk.

[0058] In an optional example of this embodiment, as shown in Figure 11, the side storage type pipe string conveying device 100 can be used for a lifting power catwalk to convey the pipe string to the drilling floor 21. The lifting power catwalk includes a lifting catwalk base 18, a bracket 19 and a ramp 20.

[0059] In another optional example of this embodiment, as shown in Figure 12, the side storage type pipe string conveying device 100 can also be used for a lifting power catwalk to convey the pipe string to the drilling floor 21. The lifting power catwalk includes a lifting catwalk base 23, a rear lifting cylinder 24, a first lifting bracket 25, a front lifting cylinder 26 and a second lifting bracket 27.

[0060] Please refer to FIG. 7 , FIG. 8 a to FIG. 8 p , FIG. 9 , and FIG. 10 a to FIG. 10 g , and the specific implementation process of the side storage type tubing string conveying device 100 proposed in an embodiment of the present disclosure will now be described in detail in conjunction with an embodiment.

[0061] In this embodiment, the side-storage-type pipe string conveying apparatus 100 has storage modules installed on both sides of the drill string delivery frame 1. The storage module located on the left side of the drill string delivery frame 1 includes two left storage mechanisms 3-L, and the storage module located on the right side of the drill string delivery frame 1 includes two right storage mechanisms 3-R. The drill string delivery frame 1 also includes left and right loading mechanisms 5-L and 5-R, and left and right kick-out mechanisms 6-L and 6-R. Furthermore, this embodiment uses the conveyance of four pipe strings (the pipe strings enter from the left side of the side-storage-type pipe string conveying apparatus 100) as an example.

[0062] 7 , the side storage type tubular string conveying device 100 proposed in the embodiment of the present disclosure is shown in the initial state of the drilling process. The first tubular string 10, the second tubular string 11, the third tubular string 12 and the fourth tubular string 13 are stored on the tubular rack. The tubular rack is raised to the drilling height, and the inner side of the tubular rack is flush with the left baffle 33-L. The left storage mechanism 3-L is in an inwardly tilted state, the left baffle 33-L is in an extended state, the right storage mechanism 3-R is in an outwardly tilted state, and the right baffle 33-R is in a vertical state. The remaining mechanism states are shown in FIG7 .

[0063] Step 1: Referring to FIG8a , the left loading mechanism 5-L moves to the unloading state, and the tilting mechanism 9 of the pipe rack moves to roll the first pipe string 10 and the second pipe string 11 through the left baffle 33-L onto the left storage mechanism 3-L;

[0064] Step 2: Referring to Figures 8b and 8c, the left loading mechanism 5-L moves from the unloading state to the loading state. The first pipe string 10 rolls into the transport chute under the action of the left loading mechanism 5-L, and the second pipe string 11 is blocked on the left storage mechanism 3-L by the outer side of the left loading mechanism 5-L.

[0065] Step 3: Referring to Figures 8d, 8e, 8f and 8g, the right kick-out mechanism 6-R extends and remains stationary, kicking the first pipe string 10 to the right side of the V-shaped groove. The right loading mechanism 5-R moves from the loading state to the unloading state, unloading the first pipe string 10 from the drill string transport chute into the right storage mechanism 3-R. The right kick-out mechanism 6-R retracts, and the right loading mechanism 5-R moves from the unloading state to the loading state.

[0066] Step 4: Referring to Figures 8h and 8i, the left loading mechanism 5-L moves from the loading state to the unloading state and then to the loading state, and the second pipe string 11 rolls into the drill string transport chute;

[0067] Step 5: Referring to Figures 8j and 8k, the tilting mechanism 9 is actuated to roll the third pipe string 12 and the fourth pipe string 13 onto the left storage mechanism 3-L via the left baffle 33-L. The left baffle 33-L is vertical, the right storage mechanism 3-R is tilted inward, and the adjustment pulley 41 and the transport pulley 2 move forward to contact the lower ends of the first pipe string 10, the second pipe string 11, the third pipe string 12, and the fourth pipe string 13 to reduce the impact of sliding down during the pipe string lifting process. The pipe string loading process is now completed.

[0068] Step 6: The side storage type pipe string conveying device 100 of the embodiment of the present disclosure is lifted or pulled up to the height of the drilling floor;

[0069] Step 7: Referring to FIG81 , the transport pulley 2 pushes the second pipe string 11 in the transport chute to the wellhead (rathole) and is then lifted away by the traveling crane system. At the same time, the transport pulley 2 retreats to its initial position, completing the transport operation of the first pipe string (the second pipe string 11).

[0070] Step 8: Referring to Figures 8m and 8n, the right loading mechanism 5-R moves from the loading state to the unloading state and then to the loading state. The first pipe string 10 rolls into the transport chute. The transport pulley 2 pushes the first pipe string 10 in the transport chute to the wellhead (rathole) and is then lifted away by the traveling crane system. At the same time, the transport pulley 2 retreats to its initial position, completing the transportation operation of the second pipe string (the first pipe string 10).

[0071] Step 9: Referring to Figures 8o and 8p, the left loading mechanism 5-L moves from the loading state to the unloading state and then to the loading state. The third pipe string 12 rolls into the transport chute. The transport pulley 2 pushes the third pipe string 12 in the transport chute to the wellhead (rat hole) and is then lifted away by the traveling crane system. At the same time, the transport pulley 2 retreats to its initial position, completing the transport operation of the third pipe string (third pipe string 12). The above actions are repeated to complete the transport operation of the fourth pipe string (fourth pipe string 13).

[0072] Step 10: The side storage type pipe string conveying device 100 of the embodiment of the present disclosure is lowered to the ground, completing the entire drill delivery process. Repeating the above steps can complete the continuous drill delivery operation.

[0073] Please refer to FIG9 to FIG10g to explain in detail the specific drilling process of the side storage type pipe string conveying device 100:

[0074] 9 , the initial state of the drill-throwing process of each mechanism of the side storage type tubular string conveying device 100 is shown. The pipe rack is lowered to the drill-throwing height, and the left baffle 33-L is flush with the inner side of the pipe rack after being flattened. The left storage mechanism 3-L and the right storage mechanism 3-R are in an outwardly tilted state, and the left baffle 33-L and the right baffle 33-R are in a vertical state. The states of the remaining mechanisms are shown in FIG9 .

[0075] Step 1: The side storage type pipe string conveying device 100 of the embodiment of the present disclosure is lifted or pulled up to the height of the drilling floor;

[0076] Step 2: Referring to Figure 10a, the transport pulley 2 moves to the front end of the drill string, the traveling lifting system places the fifth pipe string 14 on the transport pulley 2, operates the traveling lifting system to lower and operates the transport pulley 2 to retreat at the same time, until the fifth pipe string 14 completely falls into the transport chute of the drill string frame 1, separates the fifth pipe string 14 from the traveling lifting system, and continues to operate the transport pulley 2 to retreat to the appropriate position of the front end of the adjustment pulley 41.
