Description

Technical Field

[0001] The utility model relates to the technical field of oil drilling platforms, in particular to an oil drilling platform with good stabilization effect. Background Art

[0002] Oil drilling platforms are large offshore structures primarily used for drilling and extracting oil and natural gas. These platforms typically include extraction facilities, residential areas, and the ability to temporarily store oil and natural gas until they are transported to land-based refineries for processing. Depending on the type of structure, oil drilling platforms can be categorized as fixed, floating, and semi-floating. Semi-floating platforms are often used in deeper waters. These are small-waterplane mobile drilling platforms with the bulk of their buoyancy submerged. In the prior art, during the use of oil drilling platforms, anchors are often used to limit the platform's position. To prevent displacement caused by waves, dynamic positioning thrusters are often installed at the lower end of the platform. The rotation of the thruster propeller applies thrust to the platform, thereby determining its position. However, when some oil drilling platforms are in use, the horizontal force exerted by waves on the platform is large, which can easily cause the platform to sway severely and result in low stability.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 , this embodiment provides a technical solution: an oil drilling and production platform with good stabilization effect, comprising a platform 1 and a stabilizing mechanism 4;

[0022] Platform 1: There are columns 2 at the four corners of its lower surface. A lower buoyancy body 3 is provided between the lower ends of the two columns 2 corresponding to the longitudinal position. The buoyancy generated by seawater on the lower buoyancy body 3 is used to make the platform 1 float on the sea surface under the support of the columns 2. It also includes cross braces 5, which are respectively arranged between the two columns 2 corresponding to the transverse position to improve the strength of the overall device. The outer edges of the platform 1 are respectively provided with anchor windlasses 6, and the anchor chain ends of the anchor windlasses 6 are provided with anchors 7. The input end of the anchor windlass 6 is electrically connected to the output end of the oil drilling platform controller. The anchor 7 is lowered by the anchor windlass 6, and the position of the platform 1 is limited by the anchor 7. The lower ends of the outer sides of the columns 2 are provided with spiral guide plates 8 to guide the direction of the impact force exerted by the waves on the columns 2, so that the waves rush The vertical force is applied to the column 2, and the lower end of the lower floating body 3 is respectively connected to the propeller 9 through the rotating shaft. The interior of the lower floating body 3 is provided with a regulator 10. The output shaft of the regulator 10 is fixedly connected to the adjacent propeller 9 rotating shaft. The input ends of the propeller 9 and the regulator 10 are electrically connected to the output end of the oil drilling platform controller. The propeller 9 can be a screw propeller. When the platform 1 is displaced, the propeller 9 is started by the oil drilling platform controller, and the thrust generated by the propeller 9 is used to reset the platform 1. According to the direction of displacement of the oil drilling platform, the regulator 10 is started. The regulator 10 can use an electric drive to drive the propeller 9 to rotate horizontally to change the thrust direction.

[0023] Stabilizing mechanism 4: It includes a bracket 41, a guide tube 42, a rotating column 43, a push plate 44 and a spiral piece 45. The bracket 41 is respectively arranged between the two lower floating bodies 3. The guide tube 42 is provided in the mounting hole on the surface of the bracket 41. The two guide tubes 42 corresponding to the vertical position are rotatably connected with a rotating column 43. The outer arc surface of the rotating column 43 is provided with a push plate 44. The upper and lower ends of the outer arc surface of the rotating column 43 are provided with a spiral piece 45. The two spiral pieces 45 on the same rotating column 43 have opposite spiral directions. During the oil drilling process, when waves appear on the sea surface, the force exerted by the waves on the push plate 44 drives the rotating column 43 and the spiral piece 45 to rotate. Through the cooperation of the spiral piece 45 and the guide tube 42, the seawater inside the guide tube 42 is pushed to flow vertically. The directions of the seawater flowing in the two guide tubes 42 corresponding to the vertical positions are opposite, which increases the flow rate. The large oil drilling and production platform is subjected to a force in the vertical direction, which reduces the horizontal movement of the oil drilling and production platform and makes the oil drilling and production platform more stable. The stabilizing mechanism 4 also includes a sleeve 46, a fixed sleeve 47 and a torsion spring 48. The fixed sleeve 47 is respectively arranged on the outer arc surface of the rotating column 43, the sleeve 46 is respectively movably sleeved on the outer arc surface of the rotating column 43, and the push plate 44 is respectively arranged on the outer arc surface of the sleeve 46. The upper and lower ends of the outer arc surface of the sleeve 46 are movably sleeved with torsion springs 48. One end of the torsion spring 48 close to the push plate 44 is fixedly connected to the sleeve 46, and the other end of the torsion spring 48 is respectively fixedly connected to the fixed sleeve 47. When the impact force of the waves is large, the deformation of the torsion spring 48 is used to absorb the impact force, thereby reducing the probability of damage to the push plate 44. The outer side of the push plate 44 is provided with a rubber pad 11 to reduce the impact and corrosion of the waves on the push plate 44.

[0024] The working principle of the oil drilling and production platform with good stability provided by the present invention is as follows: when in use, the oil drilling and production equipment is installed on the upper surface of the platform 1, and the buoyancy generated by seawater on the lower floating body 3 is used to make the platform 1 float on the sea surface. The anchor 7 is lowered by the windlass 6, and the position of the platform 1 is restricted by the anchor 7. When the platform 1 is displaced, the propeller 9 is started by the oil drilling and production platform controller, and the thrust generated by the propeller 9 is used to reset the platform 1. During the oil drilling and production process, when waves appear on the sea surface, the force exerted by the waves on the push plate 44 drives the rotating column 43 and the spiral piece 45 to rotate through the elastic connection of the torsion spring 48. The spiral piece 45 cooperates with the guide pipe 42 to push the seawater inside the guide pipe 42 to flow vertically. The directions of the seawater flowing in the two guide pipes 42 corresponding to the vertical positions are opposite, thereby increasing the force acting on the oil drilling and production platform in the vertical direction, reducing the horizontal movement of the oil drilling and production platform, and making the oil drilling and production platform more stable.

[0025] It is worth noting that the anchor windlass 6, thruster 9 and regulator 10 disclosed in the above embodiments can be freely configured according to actual application scenarios. The anchor windlass 6 can use the JIS-F3301 model anchor windlass, the thruster 9 can use the SPE-75 underwater thruster, and the regulator 10 can use the 42HD5002I model stepping waterproof motor regulator. The oil drilling platform controller controls the operation of the anchor windlass 6, thruster 9 and regulator 10 using methods commonly used in the prior art.
