Description

Technical Field

[0001] This invention relates to the field of drilling equipment, and more particularly to a drill string transfer device, drilling equipment, and a drill string transfer method. Background Technology

[0002] In drilling operations, powered catwalks are commonly used automated equipment for pipe handling. Most new powered catwalks are capable of transporting multiple drill strings between the drilling rig and the well site. However, existing powered catwalks require consideration of how to separate individual drill strings when handling multiple strings, necessitating the addition of more drive mechanisms, which leads to cumbersome operation. Furthermore, drilling crew workers generally have low levels of education, making it difficult for them to learn and operate the equipment, increasing the risk of errors, reduced work efficiency, and significant safety risks. At the same time, more drive mechanisms also introduce more potential failure points, compromising the reliability of the equipment. Summary of the Invention

[0003] This invention provides a drill bit transfer device to solve the problems of complex structure, low working efficiency, low reliability and inconvenient operation of existing power catwalks.

[0004] This invention provides a drill bit transfer device, comprising:

[0005] A cloud beam, wherein the upper part of the cloud beam is provided with a limiting groove extending along its own length direction;

[0006] A sliding shoe mechanism is provided on the cloud beam, and the sliding shoe mechanism is used to drive multiple tubular columns in the limiting groove to move along the length direction of the cloud beam;

[0007] The inner stop mechanism has a mounting hole on the side wall of the limiting groove, and the inner stop mechanism is disposed in the mounting hole. The inner stop mechanism is adapted to switch between an extended state and a retracted state. In the extended state, the inner stop mechanism is used to limit the column so that the first column entering the limiting groove is centered in the limiting groove. In the retracted state, the inner stop mechanism retracts into the cloud beam.

[0008] According to the present invention, a drill bit transfer device includes a plurality of inner stop mechanisms, which are symmetrically arranged in pairs on the two side walls of the limiting groove.

[0009] According to a drill bit transfer device provided by the present invention, the inner stop mechanism includes:

[0010] An inner stop rod is hinged to the cloud beam via a first pin, and the inner stop rod is adapted to switch between the extended state and the retracted state.

[0011] A first driving member is hinged to the inner stop rod and the cloud beam. The first driving member is used to drive the inner stop rod to rotate around the first pin shaft so that the inner stop rod switches between the extended state and the retracted state.

[0012] According to a drill string transfer device provided by the present invention, the slipper mechanism includes:

[0013] A support slip shoe is provided in the limiting groove, and the bottom of the support slip shoe is provided with a first roller that slides in cooperation with the side wall of the limiting groove;

[0014] A guide shoe is provided on the support shoe, and a first shoe clearance groove is provided at the bottom of the guide shoe;

[0015] A conveying pipe support plate is provided on the guide slipper. The conveying pipe support plate is provided with a second slipper clearance groove along its own length direction. The position of the second slipper clearance groove corresponds to the position of the first slipper clearance groove.

[0016] A first drive assembly is disposed inside the cloud beam and connected to the support slipper. The first drive assembly is used to drive the support slipper to move along the length direction of the cloud beam.

[0017] According to a drill string transfer device provided by the present invention, the first drive assembly includes:

[0018] A chain is rotatably disposed inside the cloud beam, and the chain is connected to the support slipper;

[0019] A sprocket drive device is disposed inside the cloud beam. The sprocket drive device meshes with the chain and is used to drive the chain to reciprocate so as to drive the support slipper to move along the length direction of the cloud beam.

[0020] According to a drill string transfer device provided by the present invention, the drill string transfer device further includes:

[0021] The rod delivery mechanism includes a linear drive assembly, a rod delivery track, and a rod delivery trolley. The linear drive assembly and the rod delivery track are both disposed inside the cloud beam. The bottom wall of the limiting groove is provided with a drive rod track. The rod delivery trolley slides in cooperation with the drive rod track and the rod delivery track.

[0022] According to a drill string transfer device provided by the present invention, the rod delivery trolley includes:

[0023] The trolley body is provided with a second roller that rolls with the rod delivery track, and a limit plate is provided on the upper part of the trolley body;

[0024] A tension spring, one end of which is connected to the main body of the trolley;

[0025] A drive rod is hinged to the trolley body via a second pin. The other end of the tension spring is connected to the drive rod. The drive rod is adapted to switch between an upright state and a retracted state. In the upright state, the drive rod abuts against the limiting plate and extends from the drive rod track, slidingly engaging with the drive rod track. In the retracted state, the drive rod moves away from the limiting plate and enters the interior of the cloud beam.

[0026] According to a drill string transfer device provided by the present invention, the drill string transfer device further includes:

[0027] An outer stop mechanism is provided on at least one side of the cloud beam, and the outer stop mechanism is used to limit the position of the pipe column.

[0028] The present invention also provides a drilling equipment, the drilling equipment including the drill string transfer device described in any of the above claims.

[0029] The present invention also provides a drill string transfer method, the method being based on the drill string transfer device described in any one of the preceding claims, characterized in that it includes:

[0030] The inner stop mechanism is in the extended state, and the first tube is rolled into the limiting groove from the side opposite to the inner stop mechanism. The inner stop mechanism limits the tube so that the first tube is in the center of the limiting groove. Then, multiple tubes are rolled in sequentially so that the multiple tubes are placed side by side on one side wall of the limiting groove.

[0031] The outer stop mechanism is raised, and the sliding shoe mechanism is moved toward the trolley body so that the supporting sliding shoe abuts against the column;

[0032] When the cloud beam rises to the predetermined position, the sliding shoe mechanism is controlled to move to the standby position of the trolley body;

[0033] Control the trolley body to move away from the standby position so that the drive rod is in an upright state, and push the tubing string in the center of the limiting groove to the wellhead through the drive rod;

[0034] When the clamp catches the coupling of the pipe column, the trolley body is moved to the standby position so that the drive rod is in the retracted state;

[0035] Repeat the above steps until the tubing in the limiting groove is completely pushed out.

[0036] The drill string transfer device provided by this invention uses an inner stop mechanism on the side wall of the limiting groove to limit the tubing string, so that the first tubing string entering the limiting groove is in the center of the limiting groove, and multiple tubing strings are arranged side by side on one side wall of the limiting groove. When the first tubing string is pushed to the wellhead, the second tubing string will slide downward under the action of gravity and be in the center of the limiting groove. Therefore, there is no need to set up a tubing string separation mechanism, reducing the steps during drilling, making the operation more convenient, simplifying the structure, reducing the failure points, and improving stability.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0051] like Figure 1 and Figure 3 As shown, the drill string transfer device includes a cloud beam 6, a slipper mechanism 1, and an inner stop mechanism 3. The upper part of the cloud beam 6 is provided with a limiting groove extending along its length. The slipper mechanism 1 is disposed on the cloud beam 6 and is used to drive multiple drill strings within the limiting groove to move along the length of the cloud beam 6. The side wall of the limiting groove is provided with mounting holes, and the inner stop mechanism 3 is disposed in the mounting holes. The inner stop mechanism 3 is adapted to switch between an extended state and a retracted state. In the extended state, the inner stop mechanism 3 is used to limit the drill strings so that the first drill string entering the limiting groove is centered in the limiting groove. In the retracted state, the inner stop mechanism 3 retracts into the cloud beam 6.

[0052] The drill string transfer device provided by this invention uses an inner stop mechanism 3 on the side wall of the limiting groove to limit the tubing string, so that the first tubing string entering the limiting groove is in the center of the limiting groove, and multiple tubing strings are arranged side by side on one side wall of the limiting groove. When the first tubing string is pushed to the wellhead, the second tubing string will slide downward under the action of gravity and be in the center of the limiting groove. Therefore, there is no need to set up a tubing string separation mechanism, reducing the steps during drilling, making the operation more convenient, simplifying the structure, reducing the failure points, and improving stability.

[0053] In one embodiment of the present invention, the cloud beam 6 provides an installation foundation for the slipper mechanism 1, the inner stop mechanism 3, and other mechanisms. The intermediate foundation frame of the cloud beam 6 serves as the foundation for the entire drill string transfer device. The limiting groove of the cloud beam 6 is used to accommodate the drill string. In this embodiment, the cross-section of the limiting groove is V-shaped. Of course, the cross-sectional shape of the limiting groove is not limited to this and can be determined according to actual needs.

[0054] In one embodiment of the present invention, such as Figure 1 As shown, the drill bit transfer device includes multiple inner stop mechanisms 3, which are symmetrically arranged in pairs on the two side walls of the limiting groove. During operation, the inner stop mechanisms 3 on the same side wall of the limiting groove are simultaneously in an extended state or simultaneously in a retracted state.

[0055] In one embodiment of the present invention, such as Figure 1 As shown, the drill string transfer device includes four inner stop mechanisms 3, of which two inner stop mechanisms 3 are disposed on one side wall of the limiting groove, and two inner stop mechanisms 3 are disposed on the other side wall of the limiting groove. When the drill string rolls into the limiting groove from one side, the inner stop mechanism 3 on the other side of the limiting groove is in an extended state to limit the drill string.

[0056] In one embodiment of the present invention, such as Figure 3 As shown, the inner stop mechanism 3 includes an inner stop 31 and a first driving member. The inner stop 31 has a strip-like or sheet-like structure and is hinged to the cloud beam 6 via a first pin. The inner stop 31 is adapted to switch between an extended state and a retracted state. In the extended state, the inner stop 31 extends from the mounting hole and is in a vertical position, thereby limiting the movement of the tubular column. In the retracted state, the inner stop 31 enters the interior of the cloud beam 6 through the mounting hole.

[0057] The first driving component is hinged to the inner stop rod 31 and the cloud beam 6. The first driving component drives the inner stop rod 31 to rotate around the first pin shaft, so that the inner stop rod 31 switches between the extended state and the retracted state. Specifically, the first driving component is a stop rod drive cylinder. The piston rod of the stop rod drive cylinder is hinged to the inner stop rod 31, and the cylinder body of the stop rod drive cylinder is hinged to the cloud beam 6. The extension and retraction of the stop rod drive cylinder realizes the rotation of the inner stop rod 31 around the first pin shaft. When the inner stop rod 31 is extended, it can be ensured that the first tube that rolls into the limiting groove remains in the center of the limiting groove even under the impact of the latter two tubes, so as to facilitate the subsequent operation of the rod feeding mechanism 2.

[0058] In one embodiment of the present invention, such as Figure 2As shown, the sliding shoe mechanism 1 includes a supporting sliding shoe 11, a guide sliding shoe 12, a conveying pipe support plate 121, and a first drive assembly. The supporting sliding shoe 11 is disposed within the limiting groove and serves as a load-bearing mechanism. All components of the sliding shoe mechanism 1 are integrated on the supporting sliding shoe 11. The bottom of the supporting sliding shoe 11 is provided with first rollers 13 that slide in cooperation with the side wall of the limiting groove. Specifically, four first rollers 13 are provided on the bottom of the supporting sliding shoe 11, with two first rollers 13 disposed on one side of the bottom of the supporting sliding shoe 11 and the remaining two first rollers 13 disposed on the other side of the bottom of the supporting sliding shoe 11.

[0059] The guide shoe 12 is disposed on the support shoe 11, and the guide shoe 12 and the support shoe 11 are welded or bolted together. The bottom of the guide shoe 12 is provided with a first shoe clearance groove, which allows the drive rod 222 to pass through the bottom of the guide shoe 12 and the support shoe 11. The width of the first shoe clearance groove is greater than the thickness of the drive rod 222, ensuring that the drive rod 222 can pass freely through the first shoe clearance groove.

[0060] A conveying pipe support plate 121 is disposed on the guide slipper 12. Specifically, the conveying pipe support plate 121 is disposed at the bottom of the guide slipper 12. The conveying pipe support plate 121 is used to receive and accommodate the pipe coupling, preventing damage to the pipe thread when the pipe moves back and forth. The conveying pipe support plate 121 is disposed along the length direction of the cloud beam 6. A second slipper clearance groove 122 is disposed along its own length direction. The position of the second slipper clearance groove 122 corresponds to the position of the first slipper clearance groove. Specifically, two conveying pipe support plates 121 are disposed, and the two conveying pipe support plates 121 are spaced apart along the width direction of the cloud beam 6. A second slipper clearance groove 122 is formed between the two conveying pipe support plates 121. The center line of the second slipper clearance groove 122 is the same straight line as the center line of the first slipper clearance groove.

[0061] The first drive assembly is located inside the cloud beam 6 and is connected to the support slide shoe 11. The first drive assembly is used to drive the support slide shoe 11 to move along the length direction of the cloud beam 6.

[0062] In a preferred embodiment of the present invention, a guide ramp is provided at the end of the conveying pipe support plate 121 away from the support slipper 11. The guide ramp is located on the side where the two conveying pipe support plates 121 are close to each other, thus forming a triangular notch between the two conveying pipe support plates 121. The width of the triangular notch gradually decreases along the direction close to the support slipper 11. The two guide ramps can guide the pipe column, allowing the pipe column to easily enter the upper part of the two conveying pipe support plates 121.

[0063] In one embodiment of the present invention, such as Figure 2As shown, two sets of first drive components are provided, spaced apart along the width direction of the cloud beam 6. Each first drive component includes a chain 16 and a sprocket drive device 15. The chain 16 is rotatably disposed inside the cloud beam 6 and is connected to the support slipper 11. Specifically, the chain 16 has two connecting ends. Fixed side plates 14 are provided on both sides of the support slipper 11, and the fixed side plates 14 are bolted to the support slipper 11. The two connecting ends of the chain 16 pass around the sprocket drive device 15 and are connected to the same fixed side plate 14. The sprocket drive device 15 is disposed inside the cloud beam 6 and meshes with the chain 16. The sprocket drive device 15 drives the chain 16 to reciprocate, thereby driving the support slipper 11 to move along the length direction of the cloud beam 6. When the sprocket drive device 15 drives the chain 16 to reciprocate, the chain 16 drives the support slipper 11 to reciprocate along the length direction of the cloud beam 6.

[0064] It should be noted that the specific structure of the first drive component is not limited to the combination of chain 16 and sprocket drive device 15, but can also be a hydraulic cylinder, electric push rod or other linear drive mechanism.

[0065] In one embodiment of the present invention, such as Figure 4 As shown, the drill bit transfer device also includes a rod feeding mechanism 2. The rod feeding mechanism 2 includes a linear drive assembly 23, a rod feeding track 211, and a rod feeding trolley 22. The linear drive assembly 23 and the rod feeding track 211 are both located inside the cloud beam 6. A drive rod track 212 is provided on the bottom wall of the limiting groove. The rod feeding trolley 22 slides in conjunction with the drive rod track 212 and the rod feeding track 211. Specifically, the drive rod track 212 is located at the center of the bottom wall of the limiting groove, and the centerline of the drive rod track 212 is collinear with the centerline of the first slipper clearance groove. Figure 6 As shown, preferably, the drive rod track 212 is located between the two inner stop rod mechanisms 3. A limiting member 32 is provided at the end of the drive rod track 212 furthest from the wellhead, and the limiting member 32 is used to limit the engagement with the drive rod 222. Two rod delivery tracks 211 are provided, spaced apart along the width direction of the cloud beam 6. The cross-section of the rod delivery track 211 is U-shaped or C-shaped, and the rod delivery trolley 22 is positioned between the two rod delivery tracks 211.

[0066] In a specific embodiment of the present invention, the linear drive component 23 is a rod-feeding cylinder. The rod-feeding cylinder is arranged along the length direction of the cloud beam 6. The telescopic rod of the rod-feeding cylinder is hinged to the trolley body 221, and the cylinder body of the rod-feeding cylinder is hinged to the cloud beam 6. The rod-feeding cylinder drives the trolley body 221 to reciprocate by telescoping.

[0067] In one embodiment of the present invention, such as Figure 5As shown, the rod delivery trolley 22 includes a trolley body 221, a tension spring 224, and a drive rod 222. The trolley body 221 is provided with a second roller 223 that rolls with the rod delivery track 211. There are four second rollers 223, two of which are located on one side of the trolley body 221 and roll with the rod delivery track 211 on one side of the trolley body 221. The remaining second rollers 223 are located on the other side of the trolley body 221 and roll with the rod delivery track 211 on the other side of the trolley body 221.

[0068] A limit plate 2211 is provided on the upper part of the trolley body 221. The limit plate 2211 is vertically arranged and is welded or bolted to the trolley body 221. One end of a tension spring 224 is connected to the trolley body 221. Preferably, two tension springs 224 are provided, located on both sides of the limit plate 2211, and one end of the tension springs 224 is hooked to the trolley body 221. By providing two tension springs 224, the drive rod 222 can be balanced under force, enhancing the stability of the drive rod 222.

[0069] The drive rod 222 is hinged to the trolley body 221 via a second pin, and the other end of the tension spring 224 is connected to the drive rod 222. Preferably, a connecting rod is provided on the drive rod 222, and the other end of the tension spring 224 is hooked to the connecting rod. The drive rod 222 is adapted to switch between an upright state and a retracted state; in the upright state, the drive rod 222 abuts against the limiting plate 2211, and the drive rod 222 extends from the drive rod track 212 and slides in cooperation with the drive rod track 212; in the retracted state, the drive rod 222 moves away from the limiting plate 2211 and enters the interior of the cloud beam 6.

[0070] The tension spring 224 is always in a stretched state. When the drive rod 222 contacts the limiting member 32, the trolley body 221 is in a standby position. Under the action of the limiting member 32, the drive rod 222 switches from the upright state to the retracted state. The drive rod 222 enters the interior of the cloud beam 6, and the tension spring 224 is further stretched. When the drive rod 222 moves away from the limiting member 32, under the pulling force of the tension spring 224, the drive rod 222 switches from the retracted state to the upright state.

[0071] In one embodiment of the present invention, such as Figure 1 As shown, the drill string transfer device also includes an outer stop mechanism 4, which is disposed on at least one side of the cloud beam 6 and serves to limit the position of the drill string. Preferably, in this embodiment, the drill string transfer device further includes two outer stop mechanisms 4, which are respectively disposed on both sides of the cloud beam 6.

[0072] Specifically, the outer stop mechanism 4 includes an outer stop 41, a connecting rod 42, and an outer stop cylinder 43. The outer stop 41 is located on one side of the cloud beam 6 and extends along the length of the cloud beam 6. The outer stop 41 slides up and down with the cloud beam 6. Multiple connecting rods 42 are provided and are arranged at intervals along the length of the cloud beam 6. One end of each connecting rod 42 is rotatably engaged with the cloud beam 6, and the other end of each connecting rod 42 is hinged to the outer stop 41. One end of the outer stop cylinder 43 is rotatably hinged to the cloud beam 6, and the other end of the outer stop cylinder 43 is hinged to one end of one of the connecting rods 42. When the outer stop cylinder 43 extends, it drives the connecting rod 42 to rotate, so that the outer stop 41 rises. When the outer stop cylinder 43 retracts, it drives the connecting rod 42 to rotate in the opposite direction, so that the outer stop 41 falls. At this time, the upper plane of the outer stop 41 is flush with the upper edge of the cloud beam 6, preventing the tube from getting stuck when it rolls in and out.

[0073] In one embodiment of the present invention, the drill string transfer device further includes a push rod mechanism 5, which is disposed on the cloud beam 6 and is used to flip multiple drill strings in the limiting groove to both sides of the base. Preferably, in this embodiment, the drill string transfer device further includes two sets of push rod mechanisms 5, which are arranged at intervals along the length direction of the cloud beam 6, and the drive rod track 212 is located between the two sets of push rod mechanisms 5. Each set of push rod mechanisms 5 includes four push rod mechanisms 5, which are arranged side by side along the length direction of the cloud beam 6.

[0074] In one specific embodiment of the present invention, the push rod mechanism 5 includes a push rod 51, a long rocker arm 52, a short rocker arm 53, and a push rod cylinder 54. The shape of the push rod 51 is adapted to the cross-sectional shape of the limiting groove, and the push rod 51 is V-shaped. One end of the long rocker arm 52 and one end of the short rocker arm 53 are both hinged to the lower surface of the push rod 51, and the other end of the long rocker arm 52 and the other end of the short rocker arm 53 are both hinged to the cloud beam 6. Thus, the push rod 51, the long rocker arm 52, the short rocker arm 53, and the cloud beam 6 constitute a double rocker mechanism. One end of the push rod cylinder 54 is hinged to the cloud beam 6, and the other end of the push rod cylinder 54 is hinged to the lower surface of the push rod 51. When the push rod cylinder 54 is shortened, the push rod 51 fits against the side wall of the limiting groove, so that the upper surface of the push rod 51 is flush with the cloud beam 6, and the push rod 51 serves as part of the limiting groove. When the push rod cylinder 54 extends, the push rod 51 tilts to one side to flip the three tube columns in the limiting groove to both sides of the base.

[0075] The present invention also provides a drilling equipment, which includes the drill string transfer device described in any of the above embodiments.

[0076] The present invention also provides a drill string transfer method, the method being based on the drill string transfer device described in any of the above embodiments, the drill string transfer method comprising:

[0077] Step S100: Control the inner stop mechanism 3 to be in the extended state, and roll the first tube into the limiting groove from the side opposite to the inner stop mechanism 3. The inner stop mechanism 3 limits the tube so that the first tube is in the center of the limiting groove. Then roll in multiple tubes in sequence so that the multiple tubes are placed side by side on one side wall of the limiting groove.

[0078] Step S200: Control the outer stop mechanism 4 to rise and control the sliding shoe mechanism 1 to move towards the trolley body 221 so that the support sliding shoe 11 abuts against the tube column;

[0079] Step S300: When the cloud beam 6 rises to the predetermined position, the control shoe mechanism 1 moves to the standby position of the trolley body 221;

[0080] Step S400: Control the trolley body 221 away from the standby position so that the drive rod 222 is in an upright state, and push the tubing in the center of the limiting groove to the wellhead through the drive rod 222.

[0081] In step S500, when the clamp catches the coupling of the pipe column, the trolley body 221 is moved to the standby position so that the drive rod 222 is in the retracted state.

[0082] Step S600: Repeat the above steps until the tube column in the limiting groove is completely pushed out.

[0083] By repeating the above steps, the second and third tubing columns in the limiting groove can be pushed out completely. The above steps are the drilling process, and the swing drill process is the reverse of the drilling process. The difference is that the rod feeding mechanism 2 does not need to participate. After the first tubing column is placed in the center of the limiting groove, the second and third tubing columns are respectively slid into the cloud beam 6 along both sides of the first tubing column. After the cloud beam 6 is lowered to the horizontal, the push rod 51 rises, pushing the three tubing columns to the base at the same time, and the swing drill operation is completed.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
