Abstract

This invention relates to the field of transfer equipment technology, specifically to an instrument transfer device for oilfield logging perforation operations, comprising a mobile chassis, a lifting assembly, and a connecting plate. The connecting plate is equipped with a guide assembly, a support assembly, an adjustment assembly, and a locking assembly. The support assembly includes a connecting block with a liquid medium and guide tubes with multiple built-in connectors. The adjustment assembly uses a piston block to compress the liquid medium, driving the support rollers on the connectors to rise and fall to adapt to and support the lower surface of shaft-type instruments.

Description

Technical Field

[0001] This invention relates to the field of transfer equipment technology, specifically to an instrument transfer device for oilfield logging perforation operations. Background Technology

[0002] In oilfield logging, perforation, and downhole instrumentation operations, it is often necessary to perform surface transport, loading, unloading, and docking operations for slender shaft-type instruments such as logging tools, perforating guns, bridge plugs, and coiled tubing. These instruments are generally characterized by their long length, heavy weight, significant local variations in outer diameter, and high surface precision requirements. Therefore, high demands are placed on support stability, guidance accuracy, and smooth transport during the transport process.

[0003] In existing technologies, the aforementioned instruments are typically moved and transported using ordinary transport vehicles, brackets, or hoisting equipment. However, in practical use, existing equipment generally suffers from the following problems:

[0004] First, ordinary transport trolleys typically only have simple planar supports and lack radial restraint and guidance for axial instruments. During transport, the instruments are prone to rolling or lateral displacement, causing them to slip off the trolley and resulting in equipment damage or even personal injury.

[0005] Secondly, for long logging or perforation instruments, relying on only a few fixed support points during transportation and movement is insufficient to ensure their overall stability. They are prone to bending due to their own weight. At the same time, the support positions cannot be dynamically switched according to the movement status of the instrument during the movement, resulting in the failure of some support points or interference.

[0006] In addition, existing equipment relies heavily on manual adjustment and locking of the support mechanism during instrument transport and transfer. This is not only cumbersome to operate, but also makes it difficult to automatically switch the support position and limit the position as the instrument moves. This fails to meet the needs of oilfield logging and perforation operations for efficient and safe instrument transport. Summary of the Invention

[0007] The main objective of this invention is to provide an instrument transport equipment for oilfield logging and perforation operations, aiming to solve the problems of unstable support, difficulty in adaptive support for different axial positions, easy shaking and displacement during transport, and inability of the support mechanism to automatically switch with the movement of the instrument in existing logging instruments and perforation tools.

[0008] To achieve the above objectives, the technical solution provided by this invention is as follows: An instrument transport device for oilfield logging perforation operations includes a mobile chassis, a lifting assembly mounted on the mobile chassis, and a connecting plate mounted on the lifting assembly. The connecting plate is equipped with: The guide assembly, which is slidably mounted on the connecting plate, is used to support one end of the shaft-type instrument and guide its direction of movement. The support assembly includes a hollow connecting block disposed on a connecting plate, multiple guide tubes disposed on the connecting block and communicating with the interior of the connecting block, and multiple connectors slidably disposed within the guide tubes. The connecting block is filled with a liquid medium, and the multiple guide tubes are arranged in the same direction as the sliding direction of the guide assembly. The adjustment assembly includes a piston block that slides and seals with the connecting block and a drive component that drives the piston block to move. One end of the piston block extends into the interior of the connecting block. The piston block squeezes the liquid medium inside the connecting block. Under the pressure of the liquid medium, the connecting component moves axially along the guide tube to abut and support different positions of the instrument. The locking component is used to restrict the movement of the connector; when the guide component moves synchronously with the instrument, it can sequentially drive the corresponding locking components to switch between locked and unlocked states, so that the locking component below the shaft instrument is in the unlocked state.

[0009] Specifically, the guide assembly includes a limiting plate and a support plate on the limiting plate. The support plate is used to support one end of the instrument. A sliding block is provided on the connecting plate. A groove adapted to the limiting plate is opened on the sliding block. The limiting plate is slidably set in the groove.

[0010] Specifically, the connecting component includes a connecting column that slides and seals within the guide tube, a connecting frame mounted on the connecting column, and a support roller that rotates on the connecting frame. The connecting column slides up and down within the guide tube, and the support roller is horizontally positioned with its axis perpendicular to the sliding direction of the limiting plate.

[0011] Specifically, an elastic element and a sensor are provided between the drive element and the piston block. The elastic element provides space for the piston block to move toward the drive element when multiple support rollers are fitted and abut against the lower end of the instrument, in order to cope with changes in the cross-sectional area of ​​the instrument. The sensor is used to detect the force and displacement of the piston block.

[0012] Specifically, the locking assembly includes a limiting block on the connecting block, a locking block slidably mounted on the limiting block, and a trigger block slidably mounted on the connecting block. The sliding direction of the locking block is perpendicular to the sliding direction of the limiting plate. An inclined surface is provided on the side of the locking block near the trigger block. An elastic element two is provided between the connecting block and the locking block to drive the locking block to move away from the connecting frame. The sliding direction of the trigger block is perpendicular to the sliding direction of the locking block. When the trigger block moves in contact with the inclined surface of the locking block, it is used to change the position of the locking block relative to the connecting frame with the cooperation of the elastic element two. Several baffles are provided on the surfaces of the connecting frame and the locking block that are close to each other.

[0013] Specifically, a switching component is provided on the limiting plate. The switching component includes a switching block that slides on the limiting plate and an elastic element three located between the switching block and the limiting plate. The moving direction of the switching block is the same as the moving direction of the locking block, and the two ends of the locking block along its moving direction are set as inclined surfaces. The switching block and the trigger block are at the same height position. When the switching block passes the trigger block, it acts on the trigger block to drive it to move synchronously to the limit position, and then compresses the elastic element three to make the switching block pass over the trigger block.

[0014] Specifically, a limiting component is provided on the connecting plate. The limiting component is used to restrict the upper and lower sides of the instrument together with the support roller after the instrument moves onto the support roller.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting up a support assembly including connecting blocks, guide tubes, connectors, and liquid media, and driving a piston block to compress the liquid media, multiple connectors can extend synchronously and abut against the instrument surface. This hydraulic drive method ensures that connectors at different positions provide uniform support to the instrument and can adapt to certain shape changes or diameter differences on the instrument surface, effectively preventing deformation or damage to the instrument due to excessive local stress during transportation.

[0016] 2. By setting up locking components and using the synchronous movement of the guide components and shaft-type instruments to sequentially trigger the locking components, intelligent control of the support points is achieved. When the instrument moves to a certain position, the locking component at that position is triggered to unlock, allowing the connector to extend and support the instrument; while at other positions not reached by the instrument, the locking components remain locked to prevent the connector from accidentally extending and causing interference.

[0017] 3. The guide components not only support the instrument but also guide its movement, ensuring that the instrument can move accurately along the predetermined path. Combined with multi-point support, this ensures the stability of the instrument's transport process. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Reference Figures 1 to 6 An instrument transport device for oilfield logging perforation operations includes a mobile chassis 1, a lifting assembly 2, a connecting plate 71, a guiding assembly 3, a supporting assembly 4, an adjusting assembly 5, and a locking assembly 6.

[0027] The mobile chassis 1 is used to move the entire device. The lifting assembly 2 is mounted on the mobile chassis 1 and is used to adjust the height of the connecting plate 71. The guide assembly 3 provides initial support for the shaft-type instrument and guides it to move in a predetermined direction. The support assembly 4 provides support at different positions on the lower part of the shaft-type instrument. The adjustment assembly 5 adjusts the support state of the support assembly 4 for the shaft-type instrument. The locking assembly 6 limits and locks the connecting parts 43 that are not involved in the support.

[0028] During the movement of the shaft-type instrument, the guide component 3 drives the corresponding locking component 6 to unlock, so that the connecting piece 43 located below the shaft-type instrument can move under the pressure of the liquid medium and come into contact with the shaft-type instrument to support the shaft-type instrument at different diameter positions.

[0029] Reference Figure 1 The mobile chassis 1 is equipped with a tracked undercarriage mechanism at its bottom for easy movement within the oilfield operation site. The lifting assembly 2 is mounted on the mobile chassis 1. In this embodiment, the lifting assembly 2 is equipped with a scissor-type lifting mechanism.

[0030] Reference Figures 1 to 4 The guide component 3 includes a limiting plate 31 and a support plate 32 fixedly disposed on the limiting plate 31.

[0031] A sliding block 72 is provided on the connecting plate 71, and a groove 721 adapted to the limiting plate 31 is formed on the sliding block 72. The limiting plate 31 is slidably embedded in the groove 721. The limiting plate 31 drives the support plate 32 to slide along the extension direction of the groove 721, thereby guiding the instrument to move linearly on the connecting plate 71. The length of the groove 721 determines the movement stroke of the instrument. The support plate 32 is set on the upper part of the limiting plate 31 and extends horizontally along the extension direction of the groove 721. The support plate 32 is grooved and is used to support one end of the instrument to prevent the instrument from rolling during initial placement.

[0032] Reference Figures 2 to 5 The support component 4 includes a connecting block 41, multiple guide tubes 42 and multiple connectors 43.

[0033] The connecting block 41 is hollow and fixedly mounted on the connecting plate 71. Multiple guide tubes 42 are spaced apart on the top of the connecting block 41, and the interior of each guide tube 42 communicates with the internal cavity of the connecting block 41. The guide tubes 42 are arranged in the same direction as the sliding direction of the limiting plate 31, i.e., the guide tubes 42 are arranged sequentially along the moving path of the shaft-type instrument. The guide tubes 42 extend vertically. The connecting block 41 is filled with a liquid medium; in this embodiment, the liquid medium is hydraulic oil.

[0034] The connector 43 is slidably disposed within the guide tube 42. The connector 43 includes a connecting post 431, a connecting frame 432, and a support roller 433. The connecting post 431 is adapted to the guide tube 42, meaning the connecting post 431 slides in a sealed manner within the guide tube 42, isolating the liquid medium within the guide tube 42 from the outside. The connecting frame 432 is fixedly disposed at the end of the connecting post 431 away from the guide tube 42, i.e., the connecting frame 432 is disposed at the top of the connecting post 431. The support roller 433 is rotatably connected to the connecting frame 432. The support roller 433 is horizontally disposed, and its axis is perpendicular to the sliding direction of the limiting plate 31.

[0035] The connecting column 431 slides up and down inside the guide tube 42, driving the connecting frame 432 and the support roller 433 to rise and fall. When the shaft-type instrument is placed on the support roller 433, the support roller 433 rolls as the instrument moves, converting sliding friction into rolling friction, reducing movement resistance, and also preventing the surface of the shaft-type instrument from being scratched.

[0036] Reference Figure 2 and Figure 3 The adjusting assembly 5 includes a piston block 51 and a drive component 52. A clearance groove adapted to the piston block 51 is provided at the lower part of the connecting block 41. The piston block 51 is slidably sealed relative to the clearance groove, and one end of the piston block 51 extends into the interior of the connecting block 41, contacting the liquid medium. The drive component 52 is disposed on the connecting plate 71 and connected to the piston block 51 for driving the piston block 51 to move relative to the connecting block 41.

[0037] When the driving component 52 pushes the piston block 51 into the connecting block 41, the piston block 51 compresses the liquid medium inside the connecting block 41. The pressure is transmitted to each guide tube 42, pushing the connecting column 431 upward, which in turn drives the support roller 433 to rise until the support roller 433 abuts against the lower surface of the instrument. Since all guide tubes 42 are connected, the liquid pressure tends to be balanced. Therefore, each support roller 433 can automatically adjust its extension length according to the different diameters at different axial positions of the shaft-type instrument, realizing multi-point adaptive support for the instrument.

[0038] To accommodate changes in the cross-sectional area of ​​the instrument, when support roller 433 simultaneously corresponds to positions with large diameters on multiple shaft-type instruments, if support roller 433 cannot move away from the shaft-type instrument, the shaft-type instrument may be lifted up.

[0039] To address the above situation, an elastic element 53 and a sensor are provided between the drive component 52 and the piston block 51. The elastic element 53 provides a buffer space for the piston block 51 to move toward the drive component 52 when the multiple support rollers 433 are fitted and abutting the lower end of the instrument. When the diameter of a certain part of the instrument is large, the support roller 433 is obstructed, and the connecting column 431 cannot continue to rise. At this time, the liquid pressure increases, pushing the piston block 51 to compress the elastic element 53 in the opposite direction, thereby making room for the support roller 433 at that point and reducing the risk of lifting caused by excessive local support.

[0040] Sensors are used to detect the force and displacement of piston block 51, thereby providing feedback to the system to control the movement of drive component 52. This ensures that support roller 433 supports the shaft-type instrument while preventing it from being lifted. In this embodiment, two sensors can be used simultaneously: a distance sensor and a force sensor (not shown in the figure). The distance sensor detects the distance between piston block 51 and drive component 52. The force sensor is located on piston block 51 and connected to elastic component 53 to detect the force on elastic component 53. This ensures that support roller 433 abuts against the shaft-type instrument and provides support. When piston block 51 moves relative to drive component 52 or elastic component 53 is compressed due to increased force, a signal is sent to the signal receiving unit inside drive component 52, and the controller controls drive component 52 to control the movement of piston block 51, stopping piston block 51 from moving further.

[0041] Reference Figure 2 A positioning plate 73 is fixedly installed on the connecting plate 71. The positioning plate 73 is located at the end of the sliding block 72 in the extending direction.

[0042] The driving component 52 includes a driving source 521, a lead screw 522, and a driving plate 523. The lead screw 522 is rotatably mounted on the positioning plate 73, and its axial direction is the same as the sliding direction of the piston block 51. The driving source 521 is fixedly mounted on the connecting plate 71, and its output end is connected to the lead screw 522 to drive the lead screw 522 to rotate. The driving plate 523 has a through hole adapted to the lead screw 522, and the driving plate 523 and the lead screw 522 are in a helical sliding fit. That is, the lead screw 522 passes through the through hole of the driving plate 523. The driving plate 523 is rectangular, and one side of it abuts and overlaps with the surface of the connecting plate 71 to prevent the driving plate 523 from rotating relative to the connecting plate 71. In this embodiment, the driving source 521 is a motor.

[0043] An extension plate 511 is fixedly installed on the piston block 51 on the side away from the connecting block 41. The extension plate 511 has a through hole adapted to the lead screw 522. The lead screw 522 passes through the through hole on the extension plate 511. An elastic element 53 is disposed between the drive plate 523 and the extension plate 511.

[0044] Drive source 521 drives lead screw 522 to rotate. Through the helical sliding engagement between lead screw 522 and drive plate 523, drive plate 523 moves along the axial direction of lead screw 522. This, in turn, drives extension plate 511 and piston block 51 to move via elastic element 53. In this embodiment, two sets of drive elements 52 are provided, respectively located at both ends of the extension direction of sliding block 72, to balance the force on piston block 51.

[0045] Reference Figure 2 , Figure 5 and Figure 6 The locking component 6 includes a limiting block 61, a locking block 62, and a trigger block 63. The limiting block 61 is fixedly mounted on the sliding block 72 and extends vertically. A receiving groove 611 is provided on the limiting block 61 at a position corresponding to the connecting frame 432. The locking block 62 is slidably disposed within the receiving groove 611, and the moving direction of the locking block 62 is the same as the axial direction of the support roller 433. When the locking block 62 abuts against the connecting frame 432, it limits the connecting frame 432 and prevents it from moving further.

[0046] The trigger block 63 is also slidably disposed within the receiving groove 611, and the sliding direction of the trigger block 63 is perpendicular to the sliding direction of the locking block 62. An inclined surface is provided on the side of the locking block 62 near the trigger block 63. An elastic element 64 is provided between the locking block 62 and the connecting block 41, and the elastic element 64 is configured to drive the locking block 62 away from the connecting frame 432. When the trigger block 63 moves while abutting against the inclined surface of the locking block 62, the guiding effect of the inclined surface overcomes the elastic force of the elastic element 64, pushing the locking block 62 in a direction away from the connecting frame 432. When the trigger block 63 moves out of the inclined surface range of the locking block 62 and into the plane range, the locking block 62 abuts against the connecting frame 432. Furthermore, continued movement of the trigger block 63 will not continue to push the locking block 62 to move. In this embodiment, the inclined surface on the locking block 62 is located on the side of the locking block 62 away from the entry end of the shaft-type instrument. Multiple baffles are provided on the surfaces of the connecting frame 432 and the locking block 62 that are close to each other, so as to increase the friction of the locking block 62 on the connecting frame 432 when the connecting frame 432 and the locking block 62 abut.

[0047] The above settings enable the locking component 6 to have two working states.

[0048] Locked state: The planes of trigger block 63 and locking block 62 are in contact, and locking block 62 is in contact with connecting frame 432. Connecting frame 432 and support roller 433 cannot move.

[0049] In the unlocked state, the inclined surfaces of the trigger block 63 and the locking block 62 abut against each other. Under the action of the elastic element 64, the locking block 62 moves away from the connecting frame 432, and the connecting frame 432 and the support roller 433 can move up and down.

[0050] Reference Figure 4 A switching component 8 is provided on the limiting plate 31. The switching component 8 includes a switching block 81 and an elastic element 82. A limiting groove 311 adapted to the switching block 81 is formed on the limiting plate 31, and the switching block 81 is slidably disposed within the limiting groove 311. Its moving direction is the same as the moving direction of the locking block 62. Both ends of the locking block 62 along its moving direction are set as inclined surfaces. The switching block 81 and the trigger block 63 are at the same height position.

[0051] The elastic element 82 is located between the switching block 81 and the limiting plate 31. The elastic element 82 is configured to drive the switching block 81 to move towards the trigger block 63. When the limiting plate 31 moves the switching block 81 past the trigger block 63, it first acts on the trigger block 63, causing it to move synchronously. As the trigger block 63 moves, it switches the state of the limiting component 9. When the trigger block 63 reaches its limit position, the switching block 81 continues to move, compressing the elastic element 82 and passing the trigger block 63. Subsequently, under the action of the elastic element 82, the switching block 81 resets.

[0052] With this design, the locking component 6 is only unlocked when the limiting plate 31 (i.e., the instrument) moves to a specific locking component 6 position, allowing the lower support roller 433 to rise and support the instrument. The locking components 6 on support rollers 433 not located below the shaft instrument remain locked. This prevents support rollers 433 not located below the shaft instrument from continuously rising as the piston block 51 moves due to the absence of a shaft instrument above them, resulting in insufficient support for the shaft instrument from the support rollers 433 located below it. This would also affect the sensor's judgment of the force on the piston block 51.

[0053] Similarly, the locking components 6 are unlocked sequentially as described above. When the shaft-type instrument gradually moves off the support roller 433, the limiting plate 31 drives the switching block 81 to move in the opposite direction. The corresponding locking components 6 are locked sequentially. This ensures that while the shaft-type instrument is being removed from the equipment, the support roller 433 below it continues to support it. Furthermore, this setup allows the support components 4 to be unlocked according to the area covered by the shaft-type instrument.

[0054] Reference Figures 1 to 3 A second lead screw 74 is rotatably mounted within the slide groove 721. A second drive source 75 is fixedly mounted on the connecting plate 71. The output end of the second drive source 75 is connected to the second lead screw 74 to drive the second lead screw 74 to rotate. A second drive plate 76 is slidably mounted within the slide groove 721 along its extension direction. The second drive plate 76 is adapted to the slide groove 721 and the second drive plate 76 and the second lead screw 74 are in helical sliding engagement.

[0055] When the shaft-type instrument moves above the multiple support rollers 433, the second drive source 75 controls the second drive plate 76 to move away from the entry end of the shaft-type instrument. That is, the second drive plate 76 disengages from the limiting plate 31. This causes the limiting plate 31 to passively follow the movement of the shaft-type instrument under external force. When it is necessary to remove the shaft-type instrument from the support rollers 433, the second drive source 75 drives the second lead screw 74 to rotate, thereby controlling the movement of the second drive plate 76. The second drive plate 76 abuts against the limiting plate 31, thereby pushing the limiting plate 31 to move, and thus pushing the shaft-type instrument to move.

[0056] Reference Figure 1 and Figure 2 A limiting component 9 is provided on the connecting plate 71. A guide block 91 is fixedly provided on the connecting plate 71, and the guide block 91 is hollow. The limiting component 9 includes a guide rod 92 and a pressure plate 93. The guide rod 92 is slidably disposed within the guide block 91. The pressure plate 93 is disposed at the upper end of the guide block 91. In this embodiment, during the movement of the guide component 3, the pressure plate 93 is higher than the limiting component 9 to allow the limiting component 9 to pass through. A third drive source (not shown in the figure) is provided within the guide block 91, and the output end of the third drive source is connected to the guide rod 92 to control the up and down movement of the guide rod 92.

[0057] After the shaft-type instrument has completely moved onto the support roller 433, the pressure plate 93 is moved towards the shaft-type instrument by the drive source three until it abuts against the shaft-type instrument. The vertical direction of the shaft-type instrument is fixed by the pressure plate 93 and the support roller 433. Since the diameters of different axial sections of the shaft-type instrument are different, and the support rollers 433 of different axial sections all abut against the shaft-type instrument, the axial direction of the shaft-type instrument is fixed by multiple support rollers 433.

[0058] The specific working method is as follows: First, adjust the height of the connecting plate 71 using the lifting assembly 2 until it is flush with the worktable. Place one end of the shaft-type instrument on the support plate 32 of the guide assembly 3. Push the shaft-type instrument, which will cause the guide assembly 3 to slide along the slide groove 721.

[0059] During the movement of the instrument, the switching block 81 on the limiting plate 31 passes sequentially through the trigger blocks 63 of each locking component 6. Whenever the switching block 81 triggers a trigger block 63, the corresponding locking block 62 unlocks. At this time, the adjusting component 5 operates, and the driving component 52 pushes the piston block 51 to squeeze the liquid medium, causing the connecting piece 43 at that position to extend upwards under liquid pressure. The support roller 433 abuts against the lower surface of the instrument, providing support. Throughout the movement of the instrument, several support rollers 433 provide dynamic support from below. After the shaft-type instrument has completely moved onto the support rollers 433, the pressure plate 93 presses the shaft-type instrument from above, thus fixing it in place.

[0060] 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, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The instrument transport equipment for oilfield logging perforation operations according to claim 3, characterized in that, The locking assembly includes a limiting block on the connecting block, a locking block slidably disposed on the limiting block, and a trigger block slidably disposed on the connecting block. The sliding direction of the locking block is perpendicular to the sliding direction of the limiting block. An inclined surface is provided on the side of the locking block near the trigger block. An elastic element two is provided between the connecting block and the locking block to drive the locking block to move away from the connecting frame. The sliding direction of the trigger block is perpendicular to the sliding direction of the locking block. When the trigger block moves in a state of contact with the inclined surface of the locking block, and with the cooperation of the elastic element two, it is used to change the position of the locking block relative to the connecting frame. Several baffles are provided on the surfaces of the connecting frame and the locking block that are close to each other.

6. The instrument transport equipment for oilfield logging perforation operations according to claim 5, characterized in that, A switching component is provided on the limiting plate. The switching component includes a switching block that slides on the limiting plate and an elastic element three located between the switching block and the limiting plate. The moving direction of the switching block is the same as the moving direction of the locking block, and the two ends of the locking block along its moving direction are set as inclined surfaces. The switching block and the trigger block are at the same height position. When the switching block passes the trigger block, it acts on the trigger block to drive it to move synchronously to the limit position, and then compresses the elastic element three to make the switching block pass the trigger block.

7. The instrument transport equipment for oilfield logging perforation operations according to claim 6, characterized in that, A limiting component is provided on the connecting plate.
