摘要：

The downhole working conditions of oil fields are harsh and complex, and the working performance of tools is affected by erosion and wear after being washed by sand laden mud. In order to improve the service life of downhole tools and optimize the material with excellent anti-erosion properties, the anti-erosion properties of three common metal materials are studied in this paper. By analogy with the difficulty of abrasive water jet cutting materials, the erosion wear ability of sand laden mud on the shell of downhole tools is equivalent evaluated, and the time dimension is shortened, which is prone to analyze the erosion wear resistance of different materials. Then, a numerical model of abrasive particles impact on the material surface, based on the finite element method-smoothed particle hydrodynamics coupled method, is established, the deformation and material removal amount of different materials under the same erosion condition are compared and analyzed, and the reasons for the difference in anti-erosion properties of different materials are quantitatively analyzed from the microscopic point of view. The results showed that under the same erosion conditions, the material removal amount 40CrNi2Mo < 45Steel < Ti6Al4V, and the anti-erosion properties decreases sequentially, which is not affected by erosion velocity V (jet pressure P) and waterjet sand ratio zeta. Among them, the material deformation and removal of 40CrNi2Mo and 45Steel are similar, and the anti-erosion properties of the two are approximately the same. (c) 2022 Author(s).
