[0002] Offshore oil exploration and development refers to a series of activities aimed at finding, assessing, and extracting oil and natural gas resources in the marine environment. Various technological means are used to search for seabed oil and natural gas resources. Offshore oil exploration and development is an important component of modern industry, providing abundant energy resources for humanity and driving technological advancements and economic development. Offshore oil production platforms are crucial facilities used for offshore oil and gas exploration, extraction, production, and storage. They are the core engineering facilities for offshore oil and gas development, typically located in the center of offshore oil and gas fields, and perform multiple functions. Among these platforms, the pipeline system is a key component connecting seabed oil and gas reservoirs with offshore production facilities, undertaking important functions such as oil and gas transportation, production control, and safety assurance.

[0003] Meanwhile, existing oil production platform pipelines are usually exposed to seawater and in direct contact with it. They are subject to long-term chemical corrosion and physical impact from seawater, which can easily lead to pipeline perforation and thinning of the wall thickness. This damages the pipeline structure, increases the risk of pipeline leakage and breakage, and reduces the overall safety of use. Summary of the Invention

[0004] To overcome the problem that existing oil production platform pipelines are subject to long-term chemical corrosion and physical impact from seawater, which can easily lead to pipeline perforation and thinning of the wall thickness, thereby damaging the pipeline structure, increasing the risk of pipeline leakage and breakage, and reducing the overall safety of use, this utility model provides an oil production platform for offshore oil exploration and development.

[0005] The technical solution is as follows: An oil production platform for offshore oil exploration and development includes a fixed base and a fixed frame; the fixed base is provided in two sets, and the fixed frame is symmetrically provided on one side of the two sets of fixed bases; it also includes a protective pad, a protective layer, a guide plate, a limiting ring and a fixing column; the two sets of fixed bases are equipped with a protective pad inside, and the inner side of the protective pad is provided with a protective layer that fits the pipeline; the fixed frame is provided with several sets of connecting rods inside, and several sets of guide plates are fixed to the outer wall of the several sets of connecting rods.

[0006] Furthermore, multiple sets of bearings are symmetrically installed on the inner wall of the fixed frame, and the interior of each set of bearings has limiting holes to accommodate the connecting rods. Several sets of connecting rods are movably set with the fixed frame through the bearings.

[0007] Furthermore, connecting plates are welded to both ends of the fixing frame, and positioning plates are fixed to the lower ends of the connecting plates.

[0008] Furthermore, the inner wall of the fixed base is provided with two sets of limiting rings, and two sets of auxiliary springs are provided between the two sets of limiting rings and the fixed base. The two sets of auxiliary springs are provided with spring rubber dampers inside.

Detailed Implementation

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Offshore oil refers to petroleum resources distributed in the bedrock of the seabed. It is one of the world's most important energy resources. The formation of offshore oil is a long and complex geological process, primarily originating from organic residues in seabed sediments. These organic materials mainly come from plankton (such as algae) and bacteria. Under anaerobic conditions, these organic debris gradually transform into petroleum through microbial activity, high temperature, and high pressure. For oil development and utilization: Upstream exploration and development: Advanced geophysical exploration techniques (such as seismic exploration) are used to determine the location and scale of potential oil and gas fields, followed by drilling exploration to verify the existence and reserves of oil and gas. This stage requires significant capital and technology investment and involves high risks. Midstream production and processing: Once an oil and gas field is identified and developed, the midstream production and processing stage begins. This includes constructing offshore drilling platforms, wellheads, and other production facilities, and extracting and initially processing crude oil (such as oil-gas separation and water treatment). The crude oil produced at sea is then transported via pipelines or ships to onshore refineries for further processing. Downstream sales and distribution: Processed petroleum products are transported to end users such as gas stations and chemical plants across various regions via pipelines, railways, highways, or ships. With the continued growth in global energy demand, offshore oil, as an important energy resource, will see continued market demand growth. Technological advancements and improved exploration and development capabilities are making the extraction and utilization of offshore oil resources more efficient and feasible.

[0023] Offshore oil exploration and development refers to the entire industrial chain of activities involving the exploration, extraction, storage, and transportation of oil and gas resources in the marine environment. It encompasses geological exploration, drilling and production, processing, and subsea pipeline laying, aiming to convert seabed oil and gas resources into usable energy. Its core objective is to achieve the economical development of oil and gas resources through technological means while ensuring marine ecological security. Before conducting offshore oil exploration, it is necessary to collect a large amount of basic data, including geological, geophysical, geochemical, and marine environmental data. This data can help to initially determine the possibility of oil resources in the target area. For example, by analyzing existing geological structure maps and seismic data, the distribution and structural characteristics of seabed strata can be understood to identify areas where oil and gas accumulation may occur. Based on the results of data analysis, areas with potential oil and gas resources are selected for exploration. The selection of areas requires comprehensive consideration of various factors such as geological conditions, geographical location, marine environment, and economic costs.

[0024] Offshore oil exploration and development platforms are crucial facilities for the extraction and processing of offshore oil and gas resources. Oil production platforms are mainly divided into two categories: fixed platforms and mobile platforms. Fixed platforms include jacket platforms, jack-up platforms, and concrete gravity platforms. These platforms are fixed to the seabed by pile foundations or gravity, offering high stability and suitability for long-term operations. For example, jacket platforms are currently the most widely used fixed platforms, suitable for water depths from 10 to 300 meters. Mobile platforms include jack-up platforms, semi-submersible platforms, and drilling vessels. These platforms offer high mobility and can adapt to operational needs in different sea areas and depths. For example, semi-submersible platforms can operate in deep-sea areas and are well-suited to harsh sea conditions. The main functions of oil production platforms include: Oil and gas extraction: Extracting oil and natural gas from seabed reservoirs using drilling equipment. Oil and gas processing: Performing preliminary processing on the extracted oil and gas, such as oil-gas separation, dehydration, and desulfurization. Storage and transportation: Some platforms are equipped with oil storage facilities for temporary storage of oil and gas, which can then be transported to land via pipelines or tankers. Living and Support: Provide living facilities and work support for staff, including accommodation, catering, and medical care. As offshore oil and gas development expands into deep-sea and ultra-deep-sea areas, oil production platforms, as the core facilities for offshore oil and gas development, will provide stronger guarantees for global energy supply through continuous technological advancements and innovations.

[0025] Pipelines on production platforms in offshore oil exploration and development are crucial facilities connecting subsea oil wells, production platforms, and onshore terminals. They transport oil, natural gas, and producing water, serving as the "lifeline" of the offshore oil and gas production system. Subsea pipelines are laid on the seabed to transport oil and gas from subsea wells to production platforms or from platforms to onshore terminals. Subsea pipeline laying requires specialized pipelaying vessels and construction technology. Strict control over welding quality and pipeline alignment accuracy is essential during installation. Subsequent maintenance and inspection require regular checks and repairs of the anti-corrosion coating to prevent damage from corrosive substances in seawater and oil and gas. Leak detection utilizes advanced technologies such as distributed fiber optic and infrasound leak detection systems to monitor pipeline integrity in real time. Integrity management ensures the safe operation of pipelines through risk assessment and integrity management technologies. As offshore oil and gas development expands into deep-sea and ultra-deep-sea areas, pipeline technology continues to advance. As a key facility in offshore oil and gas production, the continuous advancement of design, construction, and maintenance technologies for production platform pipelines provides vital guarantees for offshore oil exploration and development.

[0026] like Figures 1-5 As shown, an oil production platform for offshore oil exploration and development includes a fixed base 1 and a fixed frame 4; the fixed base 1 is provided in two sets, and the fixed frame 4 is symmetrically provided on one side of the two sets of fixed base 1; it also includes a protective pad 2, a protective layer 3, a guide plate 7, a limiting ring 10 and a fixed column 14; the protective pad 2 is installed inside the two sets of fixed base 1, and the protective layer 3 that fits the pipeline is provided on the inner side of the protective pad 2; the fixed frame 4 is provided with several sets of connecting rods 8 inside, and several sets of guide plates 7 are fixed to the outer wall of several sets of connecting rods 8; several sets of bearings 9 are symmetrically installed on the inner wall of the fixed frame 4, and the bearings 9 are provided with limiting holes to accommodate the connecting rods 8 inside; the several sets of connecting rods 8 are movably set with the fixed frame 4 through the bearings 9.

[0027] Please see Figures 2-4 Both ends of the fixing frame 4 are welded with connecting plates 5. The lower end of the connecting plate 5 is fixed with a positioning plate 6. The inner wall of the fixing seat 1 is provided with two sets of limiting rings 10. Two sets of auxiliary springs 11 are provided between the two sets of limiting rings 10 and the fixing seat 1. The two sets of auxiliary springs 11 are provided with spring rubber dampers inside. The fixing seat 1 is symmetrically installed with fixing columns 14 inside. The outer wall of the fixing column 14 is provided with multiple sets of slots for locking into the ground for fastening and limiting. One end of the fixing column 14 is welded with an impact head 15.

[0028] Please see Figures 4-5An adjusting ring 16 is welded to the end of the fixed column 14 away from the impact head 15. The adjusting ring 16 has a mating hole inside. Two sets of mating plates 12 are installed inside the fixed seat 1. The fixed seat 1 has a fixing groove inside to accommodate the two sets of mating plates 12. Several sets of fixing bolts 13 are provided on the outer wall of the fixed seat 1. The two sets of mating plates 12 have threaded holes inside to accommodate the fixed seat 1. The two sets of mating plates 12 are threadedly fixed to the fixed seat 1 by several sets of fixing bolts 13.

[0029] When using the fixed seat 1 to protect the pipeline of the oil production platform, a protective layer 3 is first applied to the outer wall of the pipeline. During the application of the protective layer 3, the protective pad 2 is also applied to the outer wall of the protective layer 3, forming a double layer of protection. This effectively isolates seawater from direct contact with the pipeline, reduces the chemical corrosion of the pipeline by seawater, and protects the pipeline from seawater erosion. At the same time, the protective pad 2 and the protective layer 3 can buffer the impact of sea waves and reduce fatigue damage to the pipeline caused by repeated impacts. After the protective layer 3 and the protective pad 2 are applied to the pipeline of the oil production platform, the pipeline is laid deep into the seabed. After the pipeline has been laid for a certain distance on the seabed, the connecting plate 12 is inserted into the interior of the fixed seat 1, so that the two groups of fixed seats 1 can be initially inserted and attached to the outer wall of the protective pad 2. The fixing bolts 13 are then inserted into the interior of the fixed seat 1 and connected and fixed with the connecting plate 12. In addition, the auxiliary spring 11 can return... The spring-loaded limiting ring 10 fits snugly against the protective pad 2 on the outer wall of the pipeline to prevent it from shaking. The tool is inserted into the adjusting ring 16 and the connecting fixing column 14 is inserted into the seabed. The fixing column 14 is firmly locked into the ground through multiple sets of slots on its outer wall for fastening and limiting, preventing the fixing seat 1 from falling off due to seawater impact. At the same time, it provides additional support and fixation for the pipeline, reduces the risk of pipeline displacement, ensures the pipeline remains stable in complex marine environments, and avoids pipeline deformation caused by excessive local stress. After the fixing seat 1 is installed, the connecting plate 5 is used to connect the fixing plate and the fixing frame 4 between the two sets of fixing seats 1. The guide plate 7 inside the fixing frame 4 effectively blocks the water flow from directly impacting the pipeline, guides and changes the direction and speed of the water flow, reduces the impact force of the water flow on the pipeline, reduces local pressure changes around the pipeline, protects the pipeline structure, and enables the oil production platform pipeline to be used stably on the seabed for a long time.
