Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, and in particular to a seismically resistant and stable oil drilling platform. Background Technology

[0002] Oil extraction refers to the process of digging and extracting oil from areas with oil reserves. In the process of oil extraction, oil and gas flow from the reservoir to the bottom of the well and then rise from the bottom to the wellhead. However, oil extraction requires drilling, and oil drilling platforms are composed of multiple components. The drilling process generates significant vibrations, which can affect the working environment of operators and even cause hardware friction, accelerating wear and tear on parts and affecting the service life of drilling equipment. Therefore, it is necessary to design a vibration-resistant and stable oil drilling platform.

[0003] Chinese patent document CN217481205U discloses an oil drilling platform with an upper and lower platform arranged symmetrically. When the upper platform is subjected to vibration, it transmits the pressure downwards, causing the upper platform to move the upper mounting block and the upper anti-vibration damper downwards. After the anti-vibration damper moves, it squeezes the fixed plate, causing the fixed plate to transmit the pressure to the two lower left and right connecting rods. This causes the two lower left and right sliders to slide outside the sliding rods and simultaneously squeeze the lower spring. When the upper platform continues to transmit pressure to the lower platform, it causes the two upper connecting rods to move the two upper sliders outside the sliding rods and squeeze the upper spring. Therefore, the springs buffer the upper platform, preventing excessive vibration and reducing drilling efficiency.

[0004] The existing technology has the following problems:

[0005] I. Existing technology consists of a seismic-resistant structure and two platforms. There are few connection points between the two platforms, and the overall overturning resistance of the structure is weak.

[0006] Second, the waves at sea can easily hit the sides of the platform, causing damage to the platform's edges. Utility Model Content

[0010] The seismic support assembly includes four seismic frames. The upper ends of the four seismic frames are fixedly installed at the four corners of the lower end of the platform. Each of the four seismic frames has a connecting column fixedly installed at its lower end. Each of the four connecting columns has a shock-absorbing mechanism movably connected to its bottom. Each of the four adjacent connecting columns has a combined plate fixedly connected to its top in a surrounding manner. Each of the four combined plates has an inclined reinforcing plate fixedly installed on one side near the center of the rectangular platform. The top of each of the four reinforcing plates is fixedly connected to the lower end of the platform.

[0011] The anti-collision and shock absorption assembly includes a rectangular frame. The side of the rectangular frame closest to the center of the platform rectangle is fixedly connected to the side of the platform. The inner wall of the rectangular frame has four grooves. The inner walls of the four grooves are slidably connected to connecting plates. An arc-shaped anti-collision plate is fixedly installed on the side of the connecting plate away from the rectangular frame. Shock absorbers are fixedly installed at the four corners of the inner wall of the rectangular frame closest to the center of the platform rectangle.

[0015] Preferably, each of the connecting columns has several evenly distributed damping telescopic rods fixedly installed at its lower end on the inner side of the four shock absorbers.

The upper and lower ends of each support spring are fixedly connected to the lower end of the corresponding connecting column and the bottom of the inner wall of the fixed frame.

[0016] Preferably, sliding rods are fixedly installed on both sides of the inner wall of the rectangular frame away from the connecting plate, and sliders are slidably connected to the outer walls of the two sliding rods.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-6 As shown, a seismically resistant and stable oil drilling platform includes a platform 1, with anti-seismic support components 2 fixedly installed at the four corners of the lower end of the platform 1, and anti-collision and shock-absorbing components 3 fixedly installed on all four sides of the platform 1.

[0030] The seismic support component 2 includes four seismic frames 21. The upper ends of the four seismic frames 21 are fixedly installed at the four corners of the lower end of the platform 1. Each of the four seismic frames 21 has a connecting column 22 fixedly installed at its lower end. Each of the four connecting columns 22 has a damping mechanism movably connected to its bottom. Each of the four adjacent connecting columns 22 has a combined plate 23 fixedly connected to its top in a surrounding manner. Each of the four combined plates 23 has an inclined reinforcing plate 24 fixedly installed on one side of the rectangular center of the platform 1. The top of the four reinforcing plates 24 is fixedly connected to the lower end of the platform 1.

[0031] The anti-collision and shock absorption component 3 includes a rectangular frame 31. The side of the rectangular frame 31 closest to the center of the rectangular platform 1 is fixedly connected to the side of the platform 1. The inner wall of the rectangular frame 31 has four grooves 32 on each of its four sides. The inner walls of the four grooves 32 are slidably connected to connecting plates 33. An arc-shaped anti-collision plate 34 is fixedly installed on the side of the connecting plate 33 away from the rectangular frame 31. Shock absorbers 35 are fixedly installed at the four corners of the inner wall of the rectangular frame 31 closest to the center of the rectangular platform 1. The ends of the four shock absorbers 35 away from the center of the rectangular platform 1 are fixedly connected to the side of the connecting plate 33 closest to the rectangular frame 31.

[0032] The anti-seismic support component 2 effectively copes with earthquakes, wave impacts, and vibrations generated by drilling operations in the marine environment, reducing wear and fatigue damage to the platform structure. Furthermore, the anti-seismic frame 21, through columns 211, beams 212, and reinforcing ribs 213, forms a rigid frame that evenly distributes the weight of the platform 1 to the connecting columns 22 at the four corners, preventing excessive local stress that could lead to structural deformation, thus providing seismic resistance and further extending the service life of the platform structure. The anti-collision and shock-absorbing component 3 effectively protects against potential ship collisions, ice floe impacts, and other unexpected situations during offshore operations, reducing damage to the platform structure, lowering the risk of equipment failure, and ensuring personnel safety.

[0033] It should be noted that the supporting seismic damping component 2 provides shock absorption from the bottom, while the anti-collision shock absorption component 3 provides side protection, forming a three-dimensional seismic resistance system. The inclined design of the combined plate 23 and the reinforcement plate 24 disperses the platform load through mechanical transmission, thereby improving the anti-overturning capability.

[0034] like Figure 3 As shown, the seismic frame 21 includes four columns 211. The upper ends of the four columns 211 are fixedly installed to the lower end of the platform 1, and the lower ends of the four columns 211 are fixedly installed to the upper end of the connecting column 22. A crossbeam 212 is fixedly installed on the opposite sides of the four adjacent columns 211 in a surrounding manner.

[0035] It should be noted that the crossbeam 212 and the column 211 form a rigid frame, which enhances the torsional and bending resistance of the seismic frame and prevents vertical deformation.

[0036] like Figure 3 As shown, inclined reinforcing ribs 213 are fixedly installed on opposite sides of two adjacent crossbeams 212 at the top and bottom.

[0037] It should be noted that the reinforcing rib 213, together with the crossbeam 212 and the column 211, forms a triangular structure, which enhances the overall stiffness of the seismic frame by utilizing geometric stability. Furthermore, the reinforcing rib 213 can convert vertical loads into lateral stresses, avoiding localized stress concentrations.

[0038] like Figure 4 As shown, the shock absorption mechanism includes a fixed frame 25, the inner wall of the fixed frame 25 is slidably connected to the outer side of the corresponding connecting column 22, a base 26 is fixedly installed at the lower end of the fixed frame 25, and shock absorbers 27 are fixedly installed at the four corners of the bottom of the inner wall of the fixed frame 25. The tops of the four shock absorbers 27 are fixedly installed at the four corners of the lower end of the corresponding connecting column 22.

[0039] It should be noted that the support spring 29 is responsible for absorbing the initial vibration, and the damping telescopic rod 28 consumes vibration energy through damping force. It works in conjunction with the shock absorber 27 to reduce resonance.

[0040] like Figure 4As shown, several evenly distributed damping telescopic rods 28 are fixedly installed at the lower end of each connecting column 22, located inside the four shock absorbers 27. The lower ends of the several damping telescopic rods 28 are fixedly installed to the bottom of the inner wall of the fixed frame 25. Each damping telescopic rod 28 is movably sleeved with a support spring 29 on its outer wall. The upper and lower ends of each support spring 29 are fixedly connected to the lower end of the corresponding connecting column 22 and the bottom of the inner wall of the fixed frame 25.

[0041] like Figure 5 and Figure 6 As shown, slide rods 36 are fixedly installed on both sides of the inner wall of the rectangular frame 31 away from the connecting plate 33. Sliding blocks 37 are slidably connected to the outer walls of the two slide rods 36. Rotating plates 38 are rotatably connected to the side of the two sliding blocks 37 near the connecting plate 33. The end of the two rotating plates 38 away from the sliding blocks 37 is rotatably connected to the side of the connecting plate 33 near the rectangular frame 31.

[0042] like Figure 6 As shown, shock-absorbing springs 39 are movably sleeved on the outer walls of both slide rods 36, and the two ends of each shock-absorbing spring 39 are fixedly connected to the corresponding slider 37 and the inner wall of the rectangular frame 31 on the side that are close to each other.

[0043] It should be noted that the linkage between the rotating plate 38 and the slider 37 allows the anti-collision plate 34 to slide when impacted, absorbing kinetic energy through displacement and avoiding rigid collisions. Furthermore, the damping spring 39 pushes the slider 37 to reset after impact, causing the anti-collision plate 34 to automatically return to its upright position, enhancing continuous protection capabilities. Combined with the shock absorber 35 and the damping spring 39, a composite damping system of "rigid support + elastic buffer" is formed, enhancing impact resistance.

[0044] The working principle of this utility model is as follows: In use, platform 1 is fixed to the shallow sea using the mounting holes on the base 26. It achieves three levels of seismic resistance—foundation damping, structural reinforcement, and external protection—through the support and anti-seismic components 2 (bottom shock absorption + frame reinforcement) and the anti-collision shock absorption components 3 (side buffers). The columns 211, beams 212, and reinforcing ribs 213 form a rigid frame, evenly distributing the weight of platform 1 to the connecting columns 22 at the four corners, preventing excessive local stress that could lead to structural deformation, thus providing seismic resistance and further extending the service life of the platform structure. Furthermore, the inclined design of the combined plate 23 and the reinforcing plate 24 disperses the platform load through mechanical transmission, improving its anti-overturning capability. Simultaneously, the damping telescopic rod 28, support spring 29, and shock absorber 27 dissipate the vibration energy experienced by platform 1 during use, reducing platform 1 resonance.

[0045] Furthermore, when waves impact the side of platform 1, the linkage between the rotating plate 38 and the slider 37 allows the anti-collision plate 34 to slide upon impact, absorbing kinetic energy through displacement and preventing rigid collisions. Additionally, the shock-absorbing spring 39 pushes the slider 37 to reset after impact, causing the anti-collision plate 34 to automatically return to its normal position, enhancing continuous protection capabilities. The combination of shock absorber 35 and shock-absorbing spring 39 forms a composite shock absorption system of "rigid support + elastic buffer," enhancing impact resistance and further improving the platform's seismic resistance.
