[0002] With the development of oil and natural gas, higher and higher requirements are put forward for work efficiency. Because the traditional drilling rig has a complex structure, many transportation modules, and it takes a lot of time for dismantling and moving, which does not meet the requirements of fast moving and fast installation. Some fast-moving and fast-installing drilling rigs are disclosed in the prior art, but there are still the following disadvantages: 1) Many transportation modules; 2) Complicated dismantling, requiring more time and manpower; 3) The hoisting system of the drilling rig is complex and requires more time.

[0003] For example, Chinese Patent Document CN117072074A discloses a drill rig base that can be vertically hoisted, including a bottom layer, a middle layer, and a top layer. The middle layer is a connecting rod, and both ends are detachably connected to the bottom layer and the top layer respectively; the top layer includes a left upper seat and a right upper seat arranged on both sides of the derrick base section. The left upper seat and the right upper seat are connected into one body through a connecting frame, and at least one set of guiding mechanisms are arranged on the side parts of the upper seat and the right upper seat that match the derrick base. However, it is necessary to set a connecting rod middle layer, and it is also necessary to set up the derrick base section before the base is hoisted.

However, the height of its base is not adjustable and needs to be disassembled up and down for transportation.

[0005] CN117287129A discloses an anti-collision monitoring device and method for the top drive sling and the second floor of a drilling rig. The system includes a derrick, a crown block is arranged at the top of the derrick, and a top drive sling that can be lifted and moved by driving through the crown block, including a first module arranged on the top drive sling, a second module arranged on the second floor of the derrick, and a third module arranged on the ground or the operating platform near the derrick.

[0037] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0038] 1.

The whole process is carried out step by step, with simple and clear operation, greatly improving the installation efficiency. Most of the installation work is completed at a low position, reducing the time and risk of high-altitude operations, and improving the safety and efficiency of installation.

[0039] 2. For a fast-moving and fast-installing drilling rig, its installation method and disassembly method provided by the present invention cancel the middle layer structure of the traditional drilling rig, adopt a split design of the bottom layer and the top layer of the base, and only achieve rapid docking through a detachable connecting frame and a guiding device, significantly reducing the number of transportation modules and assembly steps. The bottom layer and the top layer of the base are pre-connected at a low position as a compact transportation unit, and the base section of the derrick and the derrick components are laid down as a whole and horizontally transported as independent modules to avoid exceeding the height standard and control the number of modules. When transporting, the base section of the derrick is separated from the base unit, but the interfaces are standardized to ensure rapid on-site positioning and installation. The foldable design of the first section of the derrick further compresses the transportation volume and reduces the number of transports, meeting the requirements of fast moving and efficient deployment for medium and shallow well operations.

[0040] 3. A fast-moving and quickly-installable drilling rig provided by the present invention has a standpipe rack system independently arranged at the bottom layer of the substructure, eliminating the monkey board structure on the derrick. This enables the derrick weight and drilling load to be directly borne by the bottom layer of the substructure, and the drill floor only needs to perform the operation function, greatly reducing its stress burden and extending the service life of the drill floor and derrick. At the same time, the structural design of the bottom layer of the substructure makes full use of space to achieve intensification and lightweight of equipment layout.

[0041] 4. A fast-moving and quickly-installable drilling rig provided by the present invention adopts an optimized connection method where the hoisting cylinder is hinged at the front end to the bottom layer of the substructure and at the rear end to the rear leg of the derrick, reducing the overall height during the horizontal installation of the derrick, making the installation position of the hoisting cylinder closer to the foundation surface, and reducing the risk of transportation height limitation. This design not only simplifies the operation steps during the hoisting process but also ensures stable center of gravity through low-position rotation and lifting, significantly reducing potential safety hazards during the installation process.

[0042] 5. A fast-moving and quickly-installable drilling rig provided by the present invention is provided with a guiding device on the top layer of the substructure, which is in movable contact with the base section or support of the derrick, ensuring the accuracy of the trajectory of the top layer of the substructure during vertical lifting, avoiding deviation or frictional loss, and improving the one-time success rate of the installation process and the stability of long-term operation of the equipment.

Specific implementation mode

[0052] The present invention will be described in detail below with reference to the accompanying drawings.

[0053] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0054] Embodiment 1

[0055] A fast - moving and fast - assembling drilling rig, as Figure 1-8 shown, includes a bottom layer 1 of the base. A support 1.4 is arranged on the bottom layer 1 of the base. A basic section 3 of the derrick that can be converted between a horizontal position and a vertical position is hinged on the support 1.4. The top of the basic section 3 of the derrick is connected with a derrick assembly. The top layer 4 of the base is detachably connected above the bottom layer 1 of the base. When the basic section 3 of the derrick is in the vertical position, the top layer 4 of the base can move vertically along the basic section 3 of the derrick and then be detachably connected to the upper part of the basic section 3 of the derrick.

[0056] As a specific illustration, well control equipment needs to be placed inside the base. These equipment are usually large in size and require a certain height space. However, the height of the base is relatively high, usually exceeding the allowable height limit of transportation vehicles, resulting in the inability to transport the whole unit by one vehicle. The traditional solution is to disassemble the base in the vertical direction, transport it to the bottom layer 1 and the top layer 4 of the base respectively, and then assemble it on site, which increases the transportation cost and the complexity of on-site installation. In this solution, the bottom layer 1 of the base, the top layer 4 of the base and the derrick base section 3 are separated. The bottom layer 1 and the top layer 4 of the base can be disassembled in the vertical direction, but during transportation, the bottom layer 1 and the top layer 4 of the base are connected together to form a compact transportation unit. The derrick base section 3 is hinged to one side of the support 1.4, and the support 1.4 has a certain elevation, so that the derrick base section 3 can rotate between the horizontal position and the vertical position without interfering with the top layer 4 of the base. In addition, the support 1.4 serves as the connection between the bottom layer 1 of the base and the derrick base section 3, and is adapted to the outer frame size of the cross section of the derrick base section 3. When the derrick base section 3 is vertical, the top layer 4 of the base can move smoothly and without deviation onto the derrick base section 3. The derrick base section 3, as the height part, is transported horizontally together with the derrick assembly, thus significantly reducing the overall transportation height and ensuring compliance with the height limit of transportation vehicles. After being transported to the site, the bottom layer 1 and the top layer 4 of the base have been pre-corresponded, and the installation of the base can be completed by simply lifting it vertically along the derrick base section 3. Moreover, through the derrick lifting device, the derrick base section 3 and the derrick assembly can be rotated from the horizontal position to the vertical position together. During the rotation process, the derrick base section 3 and the derrick assembly rotate as a whole, ensuring the stability and consistency of the rotation process, eliminating the need for separately installing the vertical lifting part of the base, and reducing the installation steps and time. In addition, in order to enable the derrick to rotate smoothly around the hinge point during the flipping process and facilitate the operation of the staff, it is required that the hinge point must be located at a lower position. Therefore, in the prior art, when the derrick flips, one side is fixed by a low-position hinge, and the other side is lapped on the top layer 4 of the base with a certain height, resulting in inconsistent support heights on both sides during the flipping process. This not only requires additional adjustment steps, but also is prone to stability risks due to the shift of the center of gravity, increasing the installation complexity and potential safety hazards. In this solution, when the derrick assembly is in the horizontal position, one side of the derrick base section 3 is hinged to the support 1.4 on one side of the bottom layer 1 of the base, and the top layer 4 of the base is sleeved on the outer periphery of the support 1.4; when the derrick base section 3 is in the vertical position, both sides of the derrick base section 3 are hinged to the support 1.4, and the top layer 4 of the base can move along the support 1.4 onto the derrick base section 3. Since the base is opened by lifting and the derrick base section 3 and the derrick assembly are rotated together, after rotation, the bottom derrick base section 3 contacts the base, and the whole base is also at a low position. One end of the derrick base section 3 is hinged to the support 1.4 on the bottom layer 1 of the base, and the other end is lapped on the bottom layer 1 of the base, ensuring that the hinge point and the lapping point of the derrick base section 3 are both at a low position and have the same height, and the center of gravity of the derrick remains stable throughout the process, reducing the risk of center of gravity shift.Furthermore, the derrick assembly continues to extend along the length direction of the derrick base section 3 to ensure the unity and compatibility of the structure, forming a continuous derrick structure. Among them, those skilled in the art can know that the connections between the bottom layer 1 of the base, the derrick base section 3, the derrick assembly, the top layer 4 of the base, and each component mentioned hereinafter are all detachable connections, so that they can be disassembled and installed to realize the transfer between different positions.

[0057] As another specific embodiment, a traveling block system is provided at the top of the derrick assembly. The top layer 4 of the base can be vertically moved along the derrick base section 3 through the traveling block system and then detachably connected to the upper part of the derrick base section 3. After removing the connection between the top layer 4 of the base and the bottom layer 1 of the base, the top layer 4 of the base is lifted vertically to the working position by using the traveling block system, and then the top layer 4 of the base is connected to the derrick base section 3. Lifting the top layer 4 of the base through the traveling block system reduces the installation steps and time, and improves the installation efficiency. And the traveling block system is the own equipment of the drilling rig, without the need to additionally increase a lifting device, and the operation is simple and convenient.

[0058] As another specific embodiment, the traveling block system includes a crown block 10 and a traveling block 7. The crown block 10 is arranged at the top of the derrick assembly, and the traveling block 7 is detachably connected to the top layer 4 of the base; a winch 2 is provided on the bottom layer 1 of the base, and the winch 2 is connected to the traveling block system. The winch 2 drives the traveling block 7 to rise through a steel wire rope, and the traveling block 7 drives the top layer 4 of the base to move vertically along the derrick base section 3 until reaching a predetermined position. The detachable connection design between the traveling block 7 and the top layer 4 of the base enables the traveling block 7 to be conveniently disassembled when the traveling block system is not needed, reducing the occupied space of the equipment and improving the flexibility of the equipment. There is no need to additionally purchase and maintain an additional lifting device, reducing the equipment input cost.

[0059] As another specific embodiment, a hoisting cylinder 12 for driving the derrick assembly to switch between the horizontal position and the vertical position is further included. The front end of the hoisting cylinder 12 is hinged to the bottom layer 1 of the base, and the rear end of the hoisting cylinder 12 is hinged to the rear leg of the derrick assembly; the bottom end of the front leg of the derrick base section 3 is hinged to a support 1.4. The telescoping of the hoisting cylinder 12 can effectively drive the derrick assembly to rotate around the hinge point, thereby reducing the height of the derrick when installed at a low horizontal position. The bottom end of the front leg of the derrick base section 3 is hinged to the support 1.4, so that the whole derrick rotates around the front leg during the hoisting process. When installed at a low horizontal position, the front leg is closer to the ground. The rear end of the hoisting cylinder 12 is hinged to the rear leg of the derrick assembly. With the same telescoping stroke of the hoisting cylinder 12, compared with being hinged to the front leg, the overall horizontal position height of the derrick can be reduced. Among them, the front leg of the derrick assembly is the leg on the front side of the derrick assembly, that is, the side close to the lower hinge point of the hoisting cylinder 12; the rear leg is the leg on the rear side of the derrick assembly. Further explanation, the hoisting cylinder 12 is hinged to the bottom layer 1 of the base on the front side of the top layer 4 of the base.

[0060] As another specific embodiment, a standpipe box 11 system is provided on the bottom layer 1 of the substructure. In the prior art, the standpipe box 11 system is arranged on the drill floor, and the drill floor needs to bear the weight of the standpipe box 11 system and the loads during the drilling process, resulting in excessive stress on the drill floor. Correspondingly, a monkey board also needs to be provided on the derrick. In this solution, the standpipe box 11 system is arranged on the bottom layer 1 of the substructure, and the monkey board structure on the derrick is cancelled. The bottom layer 1 of the substructure serves as the main stress-bearing structure, bearing the weight of the standpipe box 11 system and the loads during the drilling process, reducing the stress on the drill floor and the derrick, and reasonably utilizing the space of the bottom layer 1 of the substructure, improving the overall layout efficiency of the equipment.

[0061] As another specific embodiment, a guiding device 5 is further provided on the top layer 4 of the substructure. The guiding device 5 is in movable contact with the base section 3 of the derrick and / or the support 1.4. The guiding device 5 can be a rack and pinion, a slide rail, a roller track, etc. For example, when the guiding device 5 adopts a rack and pinion, the pinion is arranged on the top layer 4 of the substructure, and the rack is arranged on the base section 3 of the derrick and / or the support 1.4; when a slide rail or a roller track is adopted, the slide rail or the roller is arranged on the top layer 4 of the substructure, and the slideway or the track is arranged on the base section 3 of the derrick and / or the support 1.4. When the base section 3 of the derrick is in the vertical position, the top layer 4 of the substructure needs to move along the support 1.4 to the base section 3 of the derrick. The design of the guiding device 5 enables the top layer 4 of the substructure to maintain a stable trajectory during the movement, reducing the deviation caused by friction or collision. Preferably, the guiding device 5 is a roller track, which can achieve self-adaptive alignment and reduce friction at the same time.

[0062] As another specific embodiment, the bottom layer 1 of the substructure includes a left base 1.1 and a right base 1.3, and the left base 1.1 and the right base 1.3 are connected by a connecting frame 1.2; the top layer 4 of the substructure includes a left upper seat 4.2 and a right upper seat 4.4, and the left upper seat 4.2 and the right upper seat 4.4 are detachably connected by an intermediate seat 4.3; and the left base 1.1 is detachably connected to the left upper seat 4.2, and the right base 1.3 is detachably connected to the right upper seat 4.4. The left upper seat 4.2 and the left base 1.1 of the substructure are integrated into a transportation module at a low position, the right upper seat 4.4 and the right base 1.3 of the substructure are integrated into a transportation module at a low position, and the intermediate seat 4.3 is a transportation module. The number of transportation modules is reduced, and the transportation process is simplified. By vertically separating, the left upper seat 4.2, the right upper seat 4.4 and the intermediate seat 4.3 reach the working height, reducing the installation steps and time and improving the installation efficiency. Further, supports 1.4 are provided on both the left base 1.1 and the right base 1.3, and the left upper seat 4.2 and the right upper seat 4.4 are respectively sleeved on the supports 1.4 on the left base 1.1 and the right base 1.3. In addition, a lean-to support 4.1 is provided on the outer sides of the left upper seat 4.2 and the right upper seat 4.4.

[0063] As another specific embodiment, the derrick assembly includes the first derrick section 6, the second derrick section 8, and the third derrick section 9 that are detachably connected in sequence from bottom to top; the first derrick section 6 and the derrick base section 3 are of an integral structure; alternatively, the first derrick section 6 and the derrick base section 3 are detachably connected. The crown block 10 and the third derrick section 9 are removed together as a transportation module; the second derrick section 8 is removed as a transportation module; the first derrick section 6 and the derrick base section 3 are removed together as a transportation module. The segmented design of the derrick assembly makes reasonable use of transportation and storage space and improves space utilization rate.

[0064] As another specific embodiment, the first derrick section 6 is a foldable structure. The first derrick section 6 includes a left unit 6.1 and a right unit 6.2. The upper parts of the left unit 6.1 and the right unit 6.2 are hinged, and the middle parts of the left unit 6.1 and the right unit 6.2 are connected by a connecting member 6.3. The first derrick section 6 is of an "A" shape structure, with a wider cross-section than the second derrick section 8 and the third derrick section 9, and a higher height when laid down. The foldable structure enables the first derrick to be shrunk and folded during transportation, significantly reducing the overall height when laid down.

[0065] As another specific embodiment, it further includes a bracket 13 for supporting the derrick assembly when the derrick assembly is in a horizontal position. When the derrick assembly is in a horizontal position, the top of the bracket 13 contacts the bottom of the third derrick section 9, providing a stable supporting force to ensure the stability of the derrick assembly in the horizontal position. Specifically, the top of the bracket 13 is at the same height as the hinge point between the derrick base section 3 and the support 1.4. When the derrick assembly is in a horizontal position, the top of the bracket 13 is at the same height as the aforementioned hinge point, ensuring the horizontal placement of the derrick assembly, facilitating the operation of the staff, and reducing stress concentration and structural deformation caused by height differences. Of course, in some specific designs, the top of the bracket 13 can also contact the bottom of the second derrick section 8 or the first derrick section 6.
