Studies have shown that in the process of offshore oil exploitation, mechanical equipment mainly faces two major corrosion problems, namely: local corrosion and general corrosion. Specifically: (1) localized corrosion. The corrosion phenomenon is unevenly distributed on the surface of the machine, and the distribution area of the corrosion problem is relatively limited, but it is very destructive. With the increase of working time, some faults will occur in the equipment, which will affect the normal working state of the equipment. (2) Comprehensive corrosion. The distribution of corrosion problems on the surface of equipment is relatively large, and it shows a uniform distribution state, which is the most common corrosion problem. Compared with local corrosion, the destructive effect caused by general corrosion is limited. During the operation of petroleum machinery and equipment, it is necessary to assign professionals to closely observe the corrosion problems. When corrosion problems occur, they can deal with them in time to reduce the impact of corrosion on equipment work performance, to ensure that oil extraction can be carried out in an orderly manner. In a nutshell, corrosion problems will affect the working status of offshore oil machinery, increase the workload of maintenance, and at the same time damage the economic benefits of oil exploration enterprises, resulting in huge safety risks. With the continuous development of anti-corrosion technology, the use of modern anti-corrosion technology can greatly delay the damage of corrosion problems to offshore petroleum machinery, which is of great significance. (1) With the help of high-level anti-corrosion technology, the working life of offshore oil machinery and equipment can be improved. Under ocean conditions, there are many types of mechanical equipment used for offshore oil exploitation, and the requirements for the use of different mechanical equipment are different. Therefore, in order to ensure that the mechanical equipment can be used in offshore oil

To maintain normal working conditions during mining, the anti-corrosion ability of mechanical equipment can be strengthened through modern anti-corrosion technology, so as to prevent the sulfur element in oil from causing damage to the surface of equipment, thereby improving the working life of mechanical equipment. (2) Reduce the capital expenditure of oil exploration enterprises, which will help improve the economic benefits of enterprises. In the process of exploitation of offshore oil resources, if the mechanical equipment has corrosion problems, it is necessary to use maintenance funds to repair the mechanical equipment with corrosion problems

and maintenance to ensure that machinery and equipment can be maintained in good working condition. However, whether it is maintenance of offshore oil machinery equipment or replacement of equipment, it costs a lot of money, which will directly affect the income of offshore oil exploitation, and is not conducive to the healthy development of oil exploration enterprises in the future. Therefore, attention should be paid to intensifying the research on anti-corrosion technology of offshore oil machinery, which can not only ensure that the mechanical equipment has a good working condition, but also improve the economic benefits of oil companies and mining companies.

Play a positive role in helping.

Application principles of anti-corrosion technology for offshore oil machinery

Before applying offshore oil anti-corrosion technology, you need to pay attention to the following working principles.

(1) In the process of offshore oil exploitation, operators should use facts as the basis for the application of anti-corrosion technology, analyze and record various data in detail, and use the data information obtained from the analysis to feedback the corrosion of various petroleum machinery and equipment Then apply anti-corrosion technology in a targeted manner to avoid the inability to continue offshore oil production due to severe corrosion of petroleum machinery and equipment, reduce the impact of corrosion problems, and ensure that offshore oil production can be completed in an orderly manner.

(2) Continuously improve the data analysis ability, increase the application and innovation of offshore oil machinery anti-corrosion technology, learn to continuously innovate the design of anti-corrosion technology application schemes, comprehensively and meticulously analyze oil machinery data, and timely and effectively Apply anti-corrosion technology to petroleum machinery and equipment, do a good job in the anti-corrosion work of related equipment, and must not be careless, which will help improve the application quality of anti-corrosion technology in offshore petroleum machinery

Apply anti-corrosion material

A large amount of work experience shows that corrosion is a key factor restricting the performance of offshore petroleum machinery and equipment, and as the working time of machinery and equipment continues to increase, the probability of corrosion problems gradually increases. For corrosion problems, its impact is most pronounced on mechanical surfaces. Therefore, before offshore oil machinery works, it is necessary to apply anti-corrosion materials evenly on the surface of the machinery to reduce the corrosion of the corrosive medium on the surface of the machinery. In addition, in the manufacture of petroleum machinery and equipment

Before that, it is necessary to select suitable materials according to the working conditions of mechanical equipment, and pay attention to reducing the proportion of iron materials used, which will help to improve the anti-corrosion ability of offshore petroleum machinery and equipment. At present, with the continuous development of anti-corrosion technology, the types and application scenarios of anti-corrosion coatings are gradually enriched. In the field of offshore oil exploitation, asphalt is widely used, and its anti-corrosion effect is very prominent. At the same time, in order to further enhance the anti-corrosion ability of the mechanical surface, in addition to choosing asphalt materials, you can also choose

Use environmentally friendly acid-resistant coatings and inorganic polymer coatings. The application of inorganic polymer coatings can delay the corrosion rate of the surface of petroleum machinery. For environmentally friendly acid-resistant anti-corrosion coatings, it can avoid the chemical reaction between the mechanical surface and hydrogen sulfide, thereby reducing the impact of sulfide on the mechanical surface. Finally, before starting operations, the surface of petroleum machinery and equipment should be covered with uniform anti-corrosion materials. If the coverage is not uniform enough, it will cause corrosion problems of varying degrees.
