Description

Technical Field

[0001] This invention relates to the field of well workover equipment, specifically an automated drilling and workover integrated device for installation and alignment. Background Technology

[0002] With the continuous development of oil drilling and well workover operations, higher demands are being placed on the efficiency, flexibility, and adaptability of drilling equipment. Traditional drilling and workover equipment is typically single-function and presents numerous inconveniences during transportation, installation, and operation. For example, traditional equipment often requires complex hoisting and dismantling processes, places high demands on well site conditions, and is inefficient during frequent relocation operations. Furthermore, traditional equipment has a low degree of automation, is complex to operate, and struggles to achieve rapid and efficient operations.

[0003] In recent years, with the development of modular design and automation technology, more integrated and automated drilling and workover equipment has emerged. These devices, through automated control systems, have automated some operations, improving operational efficiency. However, existing technologies still have some problems. For example, the degree of equipment integration needs further improvement, some operations still require manual intervention, and there is insufficient adaptability to complex well site conditions. For instance, traditional drilling and workover equipment are usually designed separately, with limited functionality, failing to meet the needs of both drilling and workover operations. This leads to frequent equipment changes in actual operations, increasing operation time and costs. Furthermore, the installation process of traditional equipment is complex, requiring a large amount of manpower and auxiliary equipment such as cranes, and has high requirements for well site conditions. Especially in frequent relocation operations, it is inefficient and struggles to cope with complex well site conditions. Summary of the Invention

[0004] The purpose of this invention is to provide an automated drilling and workover device that can quickly, efficiently, and accurately assemble workover equipment at the well site, simplifying the installation process, saving labor, and improving efficiency.

[0009] A connecting plate is provided between two support blocks in the same mounting groove. The connecting plate is located close to the groove wall. Both ends of the connecting plate are fixed to the support blocks on the same side. A strip-shaped opening is provided in the middle of the connecting plate. The strip-shaped opening extends along the length of the mounting groove. Two parallel mounting pins are fixed in the middle of the mounting groove. The mounting pins pass through the strip-shaped opening. The adjacent end of the transverse cylinder is mounted on the mounting pin.

[0010] The rear loading mechanism slides back and forth relative to the carrier plate, and the front loading mechanism slides back and forth detachably relative to the carrier plate.

[0011] The platform module includes a platform plate, the mounting base is fixed on the platform plate, and a base plate is provided below the platform plate and rests on the wellhead ground.

The docking groove and the docking platform are detachably connected by pins on their outer sides, and the rear loading mechanism is installed on the docking platform.

[0012] The bottom of the front loading mechanism is symmetrically and rotatably equipped with first rollers. The axial direction of the first rollers is consistent with the width direction of the carrier plate. The middle part of the carrier plate is provided with two first sliding grooves extending along the length direction of the carrier plate. The width of the first sliding grooves is adapted to the first rollers, and the distance between the two first sliding grooves is adapted to the center distance of the first rollers. The first rollers are used to fall on the bottom of the first sliding grooves and roll back and forth along the first sliding grooves.

[0013] The platform is installed in a lifting manner relative to the base plate. Side plates are hinged to both sides of the platform. When the side plates swing to a horizontal state, their top surfaces are coplanar with the top surfaces of the platform. Display panels are hinged to both sides of the base plate. The display panels are located below the side plates. When the display panels swing to a horizontal state, their top surfaces are coplanar with the top surfaces of the base plate.

[0014] The rear of the vehicle chassis is symmetrically equipped with a support frame, and a U-shaped slot is fixed at the top of the support frame. The slot has a flared opening at the top. The derrick unit includes a derrick body, on which a two-tier platform is mounted. The derrick body includes four upright beams arranged in a matrix, and the upright beams are movably connected to the slot.

[0015] The top end of the lifting cylinder rod is provided with a pin hole. The derrick unit includes a derrick body, on which a second platform is mounted.

[0030] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0031] like Figures 1 to 9 As shown.

[0032] Under the overall equipment design requirements, this product is equipped with innovative designs for the platform, carrier vehicle, and shunting method.

[0033] The main structure of the entire device includes: a platform module, a shunting module, a carrier module, and a derrick unit; the shunting module assists the derrick unit in docking with the platform module and completes the interactive transfer of the derrick unit between the carrier module and the platform module.

[0034] 1) Platform Module The platform module includes a drilling platform with a designed height of 6.0m, but other heights can be adopted depending on the product scale.

[0035] The drilling rig is a metal platform structure and serves as the main bottom support structure for drilling operations. It supports the weight of the workover rig and other related equipment, ensuring the stability and safety of the equipment during workover operations. It provides a stable operating platform for workover operations, facilitating various tasks such as drilling tool tripping, equipment installation, and maintenance.

[0036] The drilling platform includes a centrally located rectangular platform 1. Side plates 3 are hinged to both sides of the long side of the platform 1. The side plates 3 swing relative to the sides of the platform 1, thus achieving a folding structure where they unfold to be coplanar with the platform 1 or fold up to stand upright on both sides of the platform 1. Two second hinge seats 4 are symmetrically arranged on the bottom surface of the side plates 3, equidistant from the sides of the platform 1. An upper working opening is provided through the platform 1 for mounting and dismounting oil rods. Four columns 2 are fixed to the bottom of the platform 1. The columns 2 are made of hollow square steel tubes. A first hinge seat 5 is provided at the top of the columns 2. A first support cylinder 6 is installed between the second hinge seats 4 and the first hinge seats 5. The first support cylinder 6 is a pneumatic cylinder and is hinged to both the first hinge seats 5 and the second hinge seats 4, respectively, for controllable support of the side plates 3, so that when the side plates 3 are unfolded, they together with the platform 1 form a complete working platform.

[0037] A third hinge seat 7 and a fourth hinge seat 8 are also provided on the upper part of the column 2. The third hinge seat 7 is located below the first hinge seat 5, and the fourth hinge seat 8 is located outside the first hinge seat 5, that is, at the outer corner of the column 2. The first, second, and third hinge seats 7 are used to form a reinforced support between the supporting cylinder and the side plate 3 and the bottom plate 9, respectively.

[0038] Below the platform 1 is a corresponding base plate 9. The length of the base plate 9 corresponds to that of the platform 1, and when folded, the length is the same for easy transportation. The width of the base plate 9 is slightly wider than that of the platform 1, with each side being 0.8m wider to provide space for the folded parts when the folding structures on both sides are closed. This is not limited to this example; the sides can also be 0.4m or 0.4m+ wider than the platform 1, as long as they can accommodate the folded side panels 3 and the display panel 12.

[0039] The base plate 9 has a centrally located lower working port corresponding to the upper working port. This lower working port is used to fully expose the wellhead for corresponding operations. Four tubing strings 10 are located around the lower working port on the top surface of the base plate 9. Each column 2 has a hollow structure with an open bottom cavity. The cross-section of each tubing string 10 is smaller than the cavity. Both the cavity and the tubing string 10 have square cross-sections. A lifting cylinder 11 is fixed to the bottom of each tubing string 10. The lifting cylinder 11 is a hydraulic cylinder, and a lifting cylinder rod is telescopically connected to the top of the lifting cylinder. The lifting cylinder rod is located inside the cavity, and its top is connected to the bottom of the platform 1. This allows the platform 1 to have a height-adjustable lifting function.

[0040] The base plate 9 has two hinged panels 12 on its long sides. The panels 12 are located below the side plate 3. The panels 12 can be unfolded by swinging outwards and placed on the ground with the top surface of the base plate 9. Together with the base plate 9, they form a larger support area on the ground, distributing the weight of the well repair equipment over a larger area and avoiding excessive pressure on the wellhead and the surrounding ground, thereby protecting the wellhead structure.

[0041] A fifth hinge seat 13 is provided on the top surface of the unfolded display panel 12. The fifth hinge seat 13 is located at the edge of the display panel 12 away from the bottom plate 9. A second support cylinder 14 is installed between the fifth hinge seat 13 and the third hinge seat 7. The second support cylinder 14 is a cylinder and is hinged to the fifth hinge seat 13 and the third hinge seat 7 respectively.

[0042] An extension plate 15 is provided at one end of the display plate 12. The outer side of the extension plate 15 is flush with the outer side of the display plate 12 away from the base plate 9. The extension plate 15 is coplanar with the display plate 12 and integrally formed. The width of the extension plate 15 is smaller than the width of the display plate 12, so that the inner side of the extension plate 15 and the display plate 12 form a recessed corner groove 16 structure. The recessed corner grooves 16 of the two extension plates 15 are arranged opposite to each other. The length of the display plate 12 corresponds to the long side of the base plate 9. Therefore, the two ends of the display plate 12 are aligned with the two ends of the base plate 9, so that the two opposite recessed corner grooves 16 and the side of the base plate 9 at that end together form a rectangular slot structure. The rectangular slot is used to cooperate with the docking platform 37 mentioned below to surround and protect the connection of the docking platform 37, assist its positioning and prevent other equipment from impacting the alignment operation.

[0043] The edge of the extension plate 15 is provided with a sixth hinge seat 17. A third support cylinder 18 is installed between the fourth hinge seat 8 and the sixth hinge seat 17. The two ends of the third support cylinder 18 are respectively hinged to the fourth hinge seat 8 and the sixth hinge seat 17. This provides enhanced support for the extended portion.

[0044] Based on the above structure, this platform module adopts a three-fold design. By lowering the platform 1, folding down the side panels 3, and folding up the display panel 12, it can be folded into a smaller size, making it convenient for transportation and transfer.

[0045] The device features three working heights: a first working height of 2.9m, which also serves as the transport height; a second working height of 4.6m; and a third working height of 6.0m. It employs a telescopic structure, with four hydraulic cylinders providing vertical lifting. This allows for "one-button" operation with manual intervention under typical working conditions, ensuring high efficiency, labor-saving operation, and accuracy.

[0046] During on-site installation, the equipment can be transported to the well site by vehicle, unloaded by a crane, and positioned on the well site. Rapid assembly is achieved by raising, unfolding, and installing the support structure (support cylinder). Relocation, transportation, installation, and commissioning are convenient, making it particularly suitable for frequent relocation situations such as scattered drilling and well workover.

[0047] The display panel 12 can unfold a larger support area and is highly adaptable to the ground conditions on site, thus reducing the quality requirements of the well site.

[0048] 2) Vehicle-mounted module

[0049] The vehicle module specifically includes a vehicle body, which is a well-workover vehicle. The well-workover vehicle is driven by both diesel and electric power, featuring a battery pack and a diesel engine as its dual power sources. The power battery uses a CATL lithium iron phosphate battery pack. Based on a heating / water-cooling temperature control system, the system automatically charges at service points, allowing the electric well-workover rig to continue operating for two hours after a power outage.

[0050] The system includes a wheeled chassis 19, on which equipment such as the power source, winch, and hydraulic power source are fixedly mounted. For operations on old wells, the work of disassembling, loading, and pulling the main rope out of the winch drum is eliminated. For operations on new wells, the work of unloading, installation, and re-threading the main rope into the drum is eliminated. The derrick, top drive, and traveling block are transported as a whole with the vehicle. The vehicle is also equipped with a hydraulic bearing mechanism for operating the hoisting derrick. At the connection between the hydraulic bearing mechanism and the derrick, a hydraulically telescopic controlled hydraulic pin is used to achieve automatic unlocking and separation after the derrick is installed.

[0051] The chassis has a rear cylinder 20 and a front cylinder 21 at its rear end and middle section, respectively, both of which are hydraulic cylinders. There are two rear cylinders 20 arranged side by side at the two edges of the rear end of the chassis, and two front cylinders 21 arranged symmetrically at the two edges of the front middle section of the chassis. The bottom end of the rear cylinder 20 is telescopically fitted with a rear cylinder rod, and the bottom end of the front cylinder 21 is telescopically fitted with a front cylinder rod. The bottom ends of both the rear cylinder rod and the front cylinder rod are hemispherical.

[0052] Two support seats 22 are centrally mounted on the rear of the top surface of the chassis 19. A lifting cylinder 23 is hinged to the support seat 22. A lifting cylinder rod is telescopically connected to the top of the lifting cylinder 23 in three stages. The top of the lifting cylinder rod is provided with a pin hole. The axis of the pin hole extends horizontally and is perpendicular to the lifting cylinder rod. Support frames 24 are symmetrically provided on both sides of the support seat 22. The bottom of the support frame 24 is fixedly installed at the two side edges of the rear of the chassis 19. The support frame 24 is upright. The top of the support frame 24 is provided with a U-shaped groove seat 25. The groove seat 25 has a flared opening at the top to facilitate the insertion of the upright beam 27 of the derrick unit.

[0053] 3) Derrick Unit During drilling or workover, the derrick unit is used to house the overhead crane, suspend traveling blocks, hooks, lifting rings, and other equipment, as well as to handle and store drill pipes, tubing, and sucker rods. Its functional structure is no different from that of existing derricks. It includes the derrick body 26 and is equipped with an integrated top drive, a second-level platform, and a working ladder. The derrick body 26 adopts a truss structure commonly used in workover derricks, a vertical two-section telescopic structure with a second-level platform, including an upper derrick and a lower derrick, suitable for operations from 25,000m to 41,000m. Each section is composed of four vertical beams 27, horizontal braces, and diagonal braces.

[0054] An mounting plate 28 is provided on the side of the lower part of the derrick body 26 away from the second platform. If it is a telescopic derrick structure, the mounting plate 28 is fixed to the lower derrick near the bottom.

[0055] The mounting plate 28 is symmetrically fixed with sleeves 29 on the left and right. The sleeves 29 are horizontally installed with mounting cylinders. The inner ends of the two mounting cylinders are telescopically connected with mounting cylinder rods 30. The mounting cylinder rods 30 are inserted into and pinned to the pin hole at the top of the lifting cylinder rod, so as to realize the rotatable connection between the derrick unit and the top of the lifting cylinder rod.

[0056] Furthermore, when the lifting cylinder rod retracts and the derrick unit is in a horizontal position, the upright beams 27 on both sides of the derrick unit fall into the slot seat 25 at the top of the support frame 24 on the same side, thereby enabling the vehicle module to support the derrick unit and facilitating its transport by vehicle.

[0057] The bottom end of the derrick (in the normal use state of being upright) has a rear leg pin hole 31 and a front leg pin hole 32. There are two mounting holes and two front leg pin holes 32, which are located at the bottom end of the upright beam 27. The front leg pin holes 32 are two pin hole structures that are far away from the second-layer frame, and the rear leg pin holes 31 are two pin hole structures that are close to the second-layer frame.

[0058] On the platform 1, at the bottom positions corresponding to the four vertical beams 27 of the vertical derrick, there are two near mounting seats 33 and two far mounting seats 34. The near mounting seats 33 are located on the side close to the carrier plate 35.

[0059] In the specific assembly process, first position the two rear leg pin holes 31 within the near mounting base 33, manually insert the pins, and then hinge the rear leg pin holes 31 to the near mounting base 33. After the derrick unit is erected, position the front leg pin holes 32 within the far mounting base 34, and then manually insert the pins to fix it, thus achieving the erection of the derrick.

[0060] 4) Shunting module

[0061] The shunting module is used to adjust the position of the vehicle-carrying module, and its specific structure includes a carrier plate 35.

[0062] The carrier plate 35 is positioned along the length of the platform plate 1 when it is specifically fitted onto the platform module.

[0063] One end of the carrier plate 35 is hinged to a ramp 36, the end of which has a sloping structure to facilitate vehicle loading and buffer the height difference when the vehicle is loaded onto the platform. The ramp 36 is hinged to the carrier plate 35 and folded to reduce its overall length, ensuring that it does not exceed the length required for transportation. This allows the vehicle to have sufficient adjustment space on the carrier plate 35 while still maintaining its length during transportation.

[0064] The carrier plate 35 is provided with a docking platform 37 extending laterally along the carrier plate 35 at one end away from the slope plate 36. The docking platform 37 has a central protrusion on the side away from the carrier plate 35, forming a "convex" shape. At the same time, the base plate 9 has a docking groove at the center of the end with the extension plate 15 that is adapted to the convex docking platform 37. Combined with the recessed groove 16 structure of the display plate 12 at this location, which is adapted to the width of the docking platform 37, the base plate 9 and the display plate 12 obtain a "convex" shaped missing space structure on the side near the carrier plate 35 that is adapted to the shape of the docking platform 37, thereby surrounding and accommodating the docking platform 37, facilitating quick positioning and connection installation, and protecting the docking point.

[0065] The docking platform 37 is provided with a first pin seat on the outer side away from the carrier plate 35, and the bottom plate 9 is provided with a second pin seat in the docking groove. Both the first pin seat and the second pin seat have pin holes and are quickly connected by inserting a pin rod.

[0066] The top surface of the docking platform 37 is higher than the top surface of the carrier plate 35. A reinforcing rib is provided between the docking platform 37 and the carrier plate 35. Since the docking platform 37 needs to bear the weight in subsequent operations, the support strength of the docking platform 37 is improved.

[0067] Two sets of limiting blocks 38 are arranged side-by-side along the edge of the carrier plate 35 near the docking platform 37. The front end face of the limiting block 38 away from the carrier plate 35 is inclined to cooperate with the tire of the vehicle module to stop the tire and prevent the vehicle from reversing excessively. The two limiting blocks 38 are arranged near the two side edges of the carrier plate 35. Two rear mounting seats are arranged side-by-side between the two limiting blocks 38. A thrust cylinder 39 is mounted on the rear mounting seat. The thrust cylinder 39 is a hydraulic cylinder. The rear end of the thrust cylinder 39 is telescopically connected to a thrust cylinder rod. The telescopic direction of the thrust cylinder 39 is forward and backward along the length of the carrier plate 35.

[0068] The docking plate is provided with a rear loading mechanism 40, and the middle part of the carrier plate 35 is provided with a front loading mechanism 41.

[0069] Both the rear loading mechanism 40 and the center alignment structure include an elongated mounting groove 42. The mounting groove 42 extends along the width direction of the carrier plate 35. The upper part of the mounting groove 42 is an open structure. Two mounting pins 43 are fixed through the center of the mounting groove 42. A transverse moving cylinder 44 is connected to the mounting pin 43. The two transverse moving cylinders 44 in the same mounting groove 42 are axially aligned and extend and retract in opposite directions. The ends of the two transverse moving cylinders 44 that are far apart from each other are connected to a transverse moving cylinder rod. A support block 46 is fixed to the end of the cylinder rod. The top surface of the support block 46 is provided with a matching groove 47 that is adapted to the bottom end of the front and rear cylinder rods. A connecting plate 45 is provided between the two support blocks 46 in the same mounting groove 42. The connecting plate 45 is located close to the groove wall of the mounting groove 42. The two ends of the connecting plate 45 are respectively fixed to the support block 46 on the same side. A strip-shaped opening 48 is provided in the middle of the connecting plate 45. The strip-shaped opening 48 extends laterally and is used to allow the mounting pin 43 to pass through and adapt to the overall displacement movement of the support block 46.

[0070] The connecting plate 45 fixes the two support blocks 46, making the support blocks 46 on both sides form an integrated structure, which can mechanically constrain synchronous left and right movement and keep the force transmission as lateral thrust. The two transverse cylinder rods in the same mounting groove 42 extend and retract synchronously in opposite directions, that is, when one extends, the other retracts and the extension and retraction amounts correspond.

[0071] Based on the above structure, after the chassis 19 is supported on the rear load mechanism 40 / front load mechanism 41, the left and right displacement of the chassis 19 can be adjusted by pushing each pair of lateral movement cylinder rods left and right. This solves the problem that the vehicle tires cannot move horizontally.

[0072] The rear end of the thrust cylinder rod is connected to the side wall of the mounting groove 42 of the rear loading mechanism 40, thereby enabling adjustment and pushing of the rear loading mechanism 40 in the front and rear positions. At the same time, the front loading mechanism 41 moves back and forth based on the gravity of the load vehicle chassis 19.

[0073] The rear loading mechanism 40 and the front loading mechanism 41 have guide structures on the carrier plate 35 and the docking platform 37 respectively for their forward and backward movement, so that the rear loading mechanism 40 and the docking platform 37 slide in a forward and backward manner, and the front loading mechanism 41 slides in a detachable forward and backward manner relative to the carrier plate 35.

[0074] Specifically, the mounting slot 42 of the front-loading mechanism 41 is symmetrically and rotatably mounted on the bottom side. The axial direction of the first rollers is aligned with the width direction of the carrier plate 35. Two first sliding grooves 49 extending along the length of the carrier plate 35 are arranged side-by-side in the middle of the carrier plate 35. The width of the first sliding grooves 49 is adapted to the width of the first rollers, and the distance between the two first sliding grooves 49 is adapted to the center distance of the first rollers. The first rollers are used to rest on the bottom of the first sliding grooves 49 and roll back and forth along the first sliding grooves 49, accommodating the forward and backward movement of the entire front-loading mechanism 41, and constraining and guiding its forward and backward sliding based on the double first roller structure. Furthermore, the design of the first sliding grooves 49 is staggered from the reversing trajectory of the vehicle module, so it does not affect the reversing operation.

[0075] In practical use, the front loading mechanism 41 is manually placed directly on the carrier plate 35, ensuring the first roller falls into the first slide groove 49 and can roll back and forth within it. The engagement with the carrier plate 35 is quick and convenient, requiring no complex limiting measures; it is ready to use immediately and disassemble easily. Compared to precision linear travel mechanisms such as slide rails, this structure is easier to maintain, more pressure-resistant and durable, and less expensive. Furthermore, it can be secured with fasteners (pins, bolts, etc.) to further enhance stability.

[0076] The guide structure between the rear loading mechanism 40 and the docking platform 37, and the guide structure of the front loading mechanism 41 relative to the carrier plate 35, can use the same structure or different structures, as long as they can cooperate with the thrust cylinder rod to achieve forward and backward displacement. Not limited to this example, other linear stroke mechanisms can also be used, such as track wheels and tracks, slide rails and sliders, optical shaft sleeves, etc.

[0077] This example still uses the above-mentioned roller and groove structure in the rear loading mechanism 40 and docking platform 37. That is, the second roller is symmetrically rotated and installed on the bottom side of the mounting groove 42 of the rear loading mechanism 40, and two second grooves 50 extending back and forth are provided on the docking platform 37. The second roller is located in the second groove 50 and rolls with the second groove 50 back and forth, so that the rear loading mechanism 40 can move back and forth adaptably when pushed and pulled by the thrust cylinder rod.

[0078] Based on the above structure, by lowering the front cylinder rod on the chassis 19 into the fitting groove 47 on the top surface of the support block 46 of the front loading mechanism 41, and lowering the rear cylinder rod into the fitting groove 47 on the top surface of the support block 46 of the rear loading mechanism 40, and by extending the front and rear cylinder rods, the chassis 19 can be lifted upwards, and the entire vehicle module can be supported on the rear loading mechanism 40 and the front loading mechanism 41. At this time, the forward and backward position can be adjusted by pushing and pulling the thrust cylinder rod, the left and right lateral position can be adjusted by extending and retracting the lateral cylinder rod, and the height can be adjusted by raising and lowering the front and rear cylinder rods. This allows the position of the chassis 19 in all three axes to be adjusted and aligned independently and precisely, ultimately ensuring that the bottom end of the derrick unit is precisely aligned with the installation position on the platform 1. In other words, the rear leg pin hole 31 at the bottom end of the upright beam 27 is located near the mounting seat 33, enabling manual pin connection installation and completing the alignment.

[0079] Based on the above structure, the specific installation methods and processes on site are as follows:

[0080] 1. Transportation

[0081] The platform module and the shunting module are transported to the well site by vehicles in their retracted state, while the vehicle module is transported to the well site as an integrated structure with the derrick unit.

[0082] Specifically:

[0083] The platform module is folded into a collapsed state for conveying, and the 35-fold ramp plate is folded into a 36-fold state for conveying, with the overall length not exceeding the limit.

[0084] The three-stage lifting cylinder rod of the vehicle module is retracted, and the derrick unit lies horizontally and is locked in the slot 25 at the top of the support frame 24.

[0085] 2. On-site installation

[0086] The platform module is unloaded by a crane and transported to the well site. The operating display panel 12 and side panel 3 are unfolded in sequence. The lifting cylinder 11 is used to lift the platform 1 to the corresponding height. The No. 1 support cylinder 6, No. 2 support cylinder 14, and No. 3 support cylinder 18 are installed to reinforce and support the display panel 12 and side panel 3, thus completing the positioning of the drilling platform.

[0087] The crane is used to unload the vehicle and hoist the shunting module to one side of the platform module, so that the docking platform 37 corresponds to the docking slot of the base plate 9. The pins are manually installed to connect the carrier plate 35 to the base plate 9. The ramp 36 is then unfolded to complete the positioning of the carrier plate 35.

[0088] 3. Vehicle in position

[0089] The vehicle module drives itself to the well site and then reverses along the length of the carrier plate 35 until its rear approaches the drilling platform.

[0090] 4. Alignment

[0091] The front loading mechanism 41 is manually placed on the carrier plate 35. When placing it, make sure that the support block 46 of the front loading mechanism 41 is positioned below the front cylinder rod in the front and rear positions.

[0092] The front cylinder block 21 and rear cylinder block 20 under the chassis 19 are activated, and the front cylinder rod and rear cylinder rod slowly fall down. During this process, the front-to-back position and left-to-right position of the rear load mechanism 40 are adjusted (the front-to-back position is adjusted by activating the thrust cylinder block 39, and the left-to-right position is adjusted by activating the transverse cylinder block 44) so ​​that the support block 46 of the rear load mechanism 40 is located under the rear cylinder rod. The left-to-right position of the front load mechanism 41 is adjusted so that its support block 46 is located under the front cylinder rod. Finally, the bottom end of the front cylinder rod falls into the fitting groove 47 of the front load mechanism 41, and the bottom end of the rear cylinder rod falls into the fitting groove 47 of the rear load mechanism 40.

[0093] The front and rear cylinder rods continue to extend until the chassis 19 is lifted up until the wheels are off the platform 35.

[0094] While keeping the vehicle module suspended, the lateral movement cylinders 44 of the front loading mechanism 41 and the rear loading mechanism 40 are activated simultaneously to adjust the position of the chassis 19 laterally along the carrier plate 35. The thrust cylinder 39 is activated to adjust the position of the rear loading mechanism 40 forward and backward. The front loading mechanism 41 works in conjunction to move the vehicle module forward and backward along the length of the carrier plate 35 until the rear leg pin hole 31 at the bottom of the derrick unit on the vehicle module is located at the corresponding position near the mounting seat 33 on the platform 1.

[0095] The retraction of the front and rear cylinder rods causes the vehicle module to fall. The pin is then manually inserted between the rear leg pin hole 31 and the mounting seat 33 to complete the hinged connection between the bottom end of the rear upright beam 27 of the derrick unit and the platform 1.

[0096] 5. Erect the derrick

[0097] Since the hinge point between the rear leg pin hole 31 and the platform 1 has been connected, the three-stage telescopic lifting cylinder 23 is activated, and the derrick unit can be pushed from horizontal to vertical through the lifting cylinder rod. The pin is manually inserted between the front leg pin hole 32 and the far mounting seat 34 to complete the erection and installation of the derrick unit and the drilling platform.

[0098] The mounting cylinder rod 30 on the derrick unit retracts and disengages from the pin hole at the top of the lifting cylinder rod, thereby completely separating the derrick unit from the vehicle module.

[0099] Through the above structural improvements and methodological optimizations, the on-site installation process of the platform and derrick has been reformed, offering the following advantages when dealing with frequent relocation operations:

[0100] In terms of transportation, the drilling platform, carrier plate 35 and derrick are transported in a modular manner. The platform module is designed with a three-fold folding design and the carrier plate 35 is designed with a folding design to reduce the size of the equipment during transportation and control the length and width of the vehicle to not exceed the limit.

[0101] In terms of installation, the derrick does not require a crane for installation. For old wells, the use of a crane to remove the derrick is eliminated, and for new wells, the use of a crane to install the derrick is eliminated, simplifying the installation process, making installation and commissioning convenient, saving labor, and improving efficiency. Furthermore, based on the platform structure improvement, ground hardening is not required, reducing the quality requirements for the well site, facilitating site relocation, and saving construction time.

[0102] Economically, it boasts strong adaptability to power and reduces power costs. The simplified bottom assembly and disassembly process saves on labor costs.

[0103] In terms of efficiency, the shunting and alignment method uses mechanical support to control the position of the chassis 19 on the left, right, front, and back. Compared with the limitations and lack of precision of vehicle driving and hoisting on the track, it can quickly align with the installation position and improve work efficiency.

[0104] In terms of precision, the hydraulic cylinder provides power and independent linear guidance, enabling independent and high-precision adjustments to the vehicle in the height, lateral, and longitudinal directions while the chassis 19 is suspended in the air. This greatly improves the alignment accuracy and ensures high-quality on-site assembly.

[0105] It should be noted that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple improvements and modifications can be made without departing from the concept of the present invention, and all such improvements and modifications should be considered to fall within the scope of protection of the present invention.
