Description

Technical Field

[0001] This utility model relates to the field of offshore oil technology, specifically a stabilization device for offshore oil drilling platforms. Background Technology

[0002] Offshore drilling platforms are large-scale marine engineering structures used for oil and gas exploration and extraction in the ocean. Their main function is to provide a stable working platform at sea, enabling drilling equipment to carry out drilling operations to discover and extract oil and gas resources on the seabed.

[0003] Existing technologies use pile legs to fix the offshore drilling platform in place on the seabed, but this method has relatively poor adaptability to different water depths. Secondly, anchoring the platform within a certain sea area requires a large area for overall layout, which may be limited in narrow sea areas, thus restricting its applicability. Another method involves setting up water tanks to regulate the center of gravity and thus stabilize the offshore drilling platform. However, the bottom of the water tanks is connected by pipes, and when water flows back from the tanks, it may be difficult to control the water flow speed, causing the water tanks to sway excessively and affecting the stability of the offshore drilling platform.

[0004] Therefore, this utility model provides a stabilization device for offshore oil drilling platforms to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

A connecting rod 8 and a chain 9 are fixedly connected to the bottom of the drilling platform 4. A first water tank 10 and a second water tank 11 are fixedly connected to the ends of the connecting rod 8 and the chain 9 away from the drilling platform 4. The gyroscope is located at the top center of the drilling platform 4. The first water tank 10 is provided with a first chamber 6 and a second chamber 7 through a partition. The second water tank 11 is provided with a third chamber 26 and a fourth chamber 27 through a partition.

[0025] The bottom ends of the first water storage tank 10 and the second water storage tank 11 are fixedly connected to a fixing plate 28. A first water delivery pipe 12 is connected to the first water storage tank 10. A first protective layer 13 is provided on the outside of the first water delivery pipe 12. The end of the first water delivery pipe 12 away from the first water storage tank 10 is connected to the second water storage tank 11.

[0026] A first liquid level sensor 24 is fixedly connected inside the first water storage tank 10, and a second liquid level sensor 25 is fixedly connected inside the second water storage tank 11. The first liquid level sensor 24 is located in the second chamber 7, which contains seawater. The second liquid level sensor 25 is located in the fourth chamber 27, which also contains seawater. Both the inner and outer sides of the second water storage tank 11 and the first water storage tank 10 are coated with anti-corrosion coatings.

[0027] A water pump 17 is installed at the top of the first water storage tank 10. A second water delivery pipe 15 is connected to the water pump 17. The second water delivery pipe 15 passes through the first water storage tank 10 and the second water storage tank 11, and is connected to a first electric three-way valve 18. The first electric three-way valve 18 is located in the first chamber 6. A third connecting water pipe 22 and a fourth connecting water pipe 23 are connected to the first electric three-way valve 18. The end of the third connecting water pipe 22, away from the first electric three-way valve 18, is placed in the shallow seawater layer of the second chamber 7. The end of the fourth connecting water pipe 23, away from the first electric three-way valve 18, is placed in the deep seawater layer of the second chamber 7. The water pump 17 is a large-scale water pump.

[0028] The lower side of the water pump 17 is connected to a second electric three-way valve 19 via a pipe. The lower side of the second electric three-way valve 19 is connected to a first connecting water pipe 20 and a second connecting water pipe 21. The end of the first connecting water pipe 20 away from the second electric three-way valve 19 is located in the shallow seawater layer of the fourth chamber 27, and the end of the second connecting water pipe 21 away from the second electric three-way valve 19 is located in the deep seawater layer of the fourth chamber 27.

[0029] A valve 16 is provided on the outside of the second water delivery pipe 15, a second protective layer 14 is provided on the outside of the second water delivery pipe 15, and anti-corrosion coatings are provided on the outside of both the second protective layer 14 and the first protective layer 13. A regulating valve 29 is provided on the first water delivery pipe 12.

[0030] Working process: When the entire system is subjected to wave swaying, the gyroscope, first liquid level sensor 24, and second liquid level sensor 25 detect the movement. Based on different swaying angles, the first water tank 10 and second water tank 11 are adjusted to correspond to the swaying direction. Figure 5 When the overall device swings with a large amplitude:

[0031] Start the water pump 17, adjust the second electric three-way valve 19 and the first electric three-way valve 18, open the valve 16, close the first water delivery pipe 12, and seawater flows from the second connecting water pipe 21 through the second electric three-way valve 19, the water pump 17, the second water delivery pipe 15, the first electric three-way valve 18, and the third connecting water pipe 22 to the first water storage tank 10, thereby causing the center of gravity to shift to the left and generating a restoring torque, thus counteracting the tilt of the platform.

[0032] When the overall device swing amplitude is relatively small, start the water pump 17, adjust the second electric three-way valve 19 and the first electric three-way valve 18, open the valve 16 and the first delivery water pipe 12, and use seawater to be transported from the second connecting water pipe 21, the second electric three-way valve 19, the water pump 17, the second delivery water pipe 15 and the third connecting water pipe 22 in the second water storage tank 11 to the first water storage tank 10. At the same time, the amount of seawater in the first water storage tank 10 increases, which increases the seawater pressure at the bottom. Combined with the overall swing and deflection, the seawater is transported along the first delivery water pipe 12 into the second water storage tank 11. However, the pipe radius of the second protective layer 14 is larger than that of the first delivery water pipe 12, so that the seawater input in the first water storage tank 10 is greater than the output, thus adjusting the center of gravity.

[0033] Conversely, when the entire device sways to the left, the water pump 17 is started, the second electric three-way valve 19 and the first electric three-way valve 18 are adjusted, the valve 16 is opened, and the regulating valve 29 is closed. Seawater is transported from the fourth connecting water pipe 23, the second conveying water pipe 15, the water pump 17, the second electric three-way valve 19, and the first connecting water pipe 20 to the second water storage tank 11 to adjust the center of gravity.

[0034] By setting up multiple first water tanks 10 and second water tanks 11, it is convenient to adjust the swaying of the platform at multiple angles.

[0035] When it is necessary to quickly change the water distribution in the water tank to resist large platform swaying, the water pump 17 can inject a large amount of water from the first water tank 10 into the second water tank 11 and open or adjust the opening size of the regulating valve 29 according to actual needs. The overall swaying can be adjusted bidirectionally through the first water delivery pipe 12. It can accurately adjust the water volume according to the slight changes in platform swaying, making the platform more stable in the process of resisting swaying. Moreover, in the face of complex sea conditions, the flexible bidirectional water injection method can adapt to various sea conditions and swaying modes, effectively improving the stability of the platform.

[0036] Adjusting the opening size of valve 29 makes the water backflow process smoother, preventing violent fluctuations in the water within the tank, thus ensuring the stable operation of the anti-sway system and avoiding rapid water flow between the second water tank 11, preventing excessive sloshing of the water within the second water tank 11 due to excessively fast water flow.
