The working conditions of the oil field are harsh. Many metal parts work under heavy loads for a long time, accompanied by corrosion, friction and wear, resulting in premature failure. It shortens its service life. Stopping production for inspection and replacing new parts not only increases the cost of materials but also affects the production of oil fields, resulting in many losses. The wear clearance of friction pairs of many metal parts in oil field is in the order of nearly millimeter. However, the treatment layer of conventional surface technology is thin, which makes it difficult to repair the surface of worn parts, and limits the application range of these technologies.
1. oil drill pipe
Oil drill pipe is one of the important tools for drilling into strata in oil drilling operations. Due to the impact, friction and corrosion of drill pipe, its surface is prone to crack, wear and corrosion, which seriously affects the safety and efficiency of drilling operations. To solve this problem, laser cladding technology has been widely used in the surface strengthening and repairing of oil drill pipes.
Through laser cladding technology, a coating with high hardness, corrosion resistance, wear resistance and high-temperature resistance is formed on the surface of the drill pipe, which can significantly improve the durability and efficiency of the drill pipe. At the same time, laser cladding technology can also repair the damage on the drill pipe surface, extend the service life of the drill pipe, and reduce the replacement cost.
2. pump rod
Pump rod is one of the important tools for oil recovery. Due to long-term corrosion and friction from underground crude oil, the rod is prone to wear, crack, deformation and other problems, which seriously affect the exploitation of crude oil and improve efficiency. In order to solve this problem, laser cladding technology is widely used in rod surface strengthening and repair.
Through laser cladding technology, a layer of high hardness and high toughness coating is formed on the surface of the rod, which can significantly improve the durability and efficiency of the rod. Laser cladding technology can also repair rod surface damage, extend rod service life,and reduce replacement costs.
3. Oil pipelines
The oil pipeline is one of the indispensable and important facilities in oil production. Because the crude oil transported often contains corrosive substances, these substances will cause corrosion and damage to the pipeline, seriously affecting the safety and stability of oil production. Therefore, laser cladding technology is widely used in oil pipeline anticorrosion and repair.
Through laser cladding technology, a coating with high corrosion resistance can be formed on the internal and external surfaces of the pipeline, significantly improving the durability and safety of the pipeline. At the same time, the laser cladding technology can also repair the damage to the pipeline surface, avoid the occurrence of pipeline leakage and other accidents, and reduce maintenance cost.
In short, the application of laser cladding technology in the oilfield can be realized on the pumping unit, which greatly improves the life and safety of the equipment, but also brings benefits to the enterprise and reduces the cost.
