In order to predict the erosion life and erosion failure time of the metal mesh, based on the rotating erosion experiments under different working conditions, the erosion mass loss of the metal mesh under different factors was measured by the weight loss method and the erosion mathematical prediction model was put forward. The erosion wear mechanism of the single-layer metal mesh was explored by using electron microscope scanner and optical microscope. The results show that the erosion rate increases exponentially with the increase of liquid velocity (0.5, 1.0, 1.5, 2.0 m/s). When the solid mass fraction (0.3%, 0.5%, 0.8%) and erosion Angle is 15°–45°, the erosion rate is proportional to the solid mass fraction and erosion Angle. After erosion, the mesh samples suffered different degree of pitting corrosion, ploughing and cutting wear, and the mesh wear was local wear. Compared with the experimental value, the error of the erosion mathematical model is less than 20%, which has a certain reliability, and has an important reference significance for guiding the production control of sand oil Wells.

为预测金属网的冲蚀寿命和冲蚀失效时间，基于不同工况下的旋转冲蚀实验，采用失重法和冲蚀数学预测法测量了不同因素下金属网的冲蚀质量损失。模型被提出。利用电子显微镜扫描仪和光学显微镜探索了单层金属网的冲蚀磨损机理。结果表明，侵蚀速率随着液体速度的增加（0.5、1.0、1.5、2.0 m/s）呈指数增加。当固体质量分数（0.3%、0.5%、0.8%）和冲蚀角为15°～45°时，冲蚀速率与固体质量分数和冲蚀角成正比。冲刷后的网状试样发生不同程度的点蚀、犁切磨损，网眼磨损为局部磨损。与实验值相比，侵蚀数学模型的误差小于20%，具有一定的可靠性，对指导砂油井的生产控制具有重要的参考意义。
