| 摘 要： | 为减少储气库储层出砂对井筒及各工具冲蚀影响，本文利用数值模拟方法，根据实际井筒造斜方式和动力学相似原理，建立了冲蚀模型，然后以颗粒直径对磨蚀率影响最大这一理论为基础，研究了砂砾形状系数与磨蚀率间的关系。结果表明，对边界越不光顺砂砾，气相携砂能力越强，磨蚀效应越小。

| Abstract: | In order to reduce the impact of sand production in the gas reservoir on the wellbore and various tools, this paper uses the numerical simulation method to establish the erosion model according to the actual wellbore method and the principle of dynamic similarity, and then the influence of particle diameter on the abrasive rate. Based on the largest theory, the relationship between the grit shape coefficient and the abrasion rate is studied. The results show that the more the boundary is not smooth, the stronger the gas carrying capacity of the gas phase and the smaller the abrasive effect. |
