摘　　要：为了对目标井地层砂样采取更具有针对性砾石优选,提高砾石充填防砂效率,采用基于颗粒离散元素法的数值模拟方法进行不同类型、不同粒径砾石的防砂效果实验,并提出了一种综合因子的概念,可将防砂效果进行量化。通过数值模拟实验结果与常用方法的对比,验证了数值模拟手段进行防砂砾石选择的可行性,进而设计了对不同目标井地层砂样更具针对性的防砂砾石粒径选择方法。利用该方法可优选出最佳砾石尺寸,同时达到对出砂地层进行高效精确防砂、减少室内实验时间和资源浪费,节省实验费用的目的。In order to make the selection of sand control gravel more targeted to the formation sand sample of the target well,thus,to improve the sand control efficiency of gravel packing,the numerical simulation method based on the particle discrete element method was used to test the sand control effect of different types and particle sizes of gravel,and a comprehensive factor was proposed to quantify the sand control effect.Through the comparison between the numerical simulation experimental results and common methods,the feasibility of selecting sand control gravel by numerical simulation was verified,and then a more targeted sand control gravel particle size selection method for formation sand samples of different target wells was designed.The results show that by using this method to select the best gravel size can be selected so as to achieve efficient sand control for sand-producing formation,reduce the waste of indoor experiment time and resources,and save the experiment cost.
