1. Application of Samarium Cobalt in Petroleum Industry
SmCo magnets, as a high-performance rare earth permanent magnet materials, have excellent high temperature resistance, corrosion resistance and high magnetic properties, especially in high temperature, high pressure and corrosive environments. . Samarium cobalt magnets are widely used in petroleum industry equipment, such as: Logging Tools, magnetic pumps and valves, Downhole Turbines, bearingless drilling motors, magnetic separation equipment, etc. According to industry estimates, the market size of samarium cobalt magnets in the petroleum field accounts for approximately 10%-15% of the total global samarium cobalt magnet market, with an annual market value of approximately US$500 million to US$1,000 million. As more oil companies expand into complex geological environments and the demand for reliable and high-performance equipment grows, the market potential of samarium cobalt magnets in the oil industry may further expand.
2. Why are SmCo magnet more suitable for the petroleum industry?
SmCo magnets have remarkable adaptability in the petroleum industry. SmCo magnet have good adaptability and high fit in petroleum application scenarios where high temperature, high pressure, and corrosive environments are common, ensuring efficient and stable operation of equipment and improving the efficiency and effectiveness of all aspects of oil extraction. reliability. The following are the advantages of samarium cobalt magnets in the petroleum industry:
2.1. High temperature resistance performance requirements
The increase in the depth of oil exploration and production will cause the underground temperature to rise. For example, when mining in deep and ultra-deep oil reservoirs, the ambient temperature of the logging equipment often exceeds 300°C. SmCo magnets have a high Curie temperature, and the T series ultra-high temperature SmCo has a maximum operating temperature of 550°C. This feature ensures that samarium cobalt magnets can maintain stable magnetic properties in high temperature environments, ensure accurate magnetic positioning, and accurately control the direction of drilling tools. It improves mining efficiency and success rate, reduces geological risks, and also provides reliable support for reserve assessment and mining plan planning.
2.2. High magnetic energy product requirements
In equipment such as magnetic pumps and bearingless drilling motors, the high magnetic energy products of samarium cobalt magnets is indispensable. The magnetic pump uses high magnetic energy product to generate a strong magnetic field to drive the impeller, achieving leakage-free transportation and preventing oil leakage pollution and safety hazards; the bearingless drilling motor relies on it to provide a strong magnetic field force to support the stable suspension operation of the rotor, reduce friction loss, and extend the life of the equipment. Reduce maintenance frequency and costs to ensure continuous and efficient advancement of drilling operations.
2.3. Corrosion resistance requirements
Oil production and transportation contain a variety of corrosive media. Offshore platforms are corroded by seawater salt and acidic gases, and onshore oil fields are also threatened by corrosion such as H₂S and halogen ions. In equipment such as magnetic separation equipment and downhole instruments that are exposed to corrosive environments for a long time, samarium cobalt magnets must have stable structure and performance. They must be resistant to H₂S and halogen corrosion under the protection of special coatings, maintain equipment integrity and functional stability, and ensure the quality of crude oil. Reduce equipment loss and replacement costs, improve production safety and economic benefits, and lay a solid foundation for long-term stable production.
