Accurate prediction of sand production in unconsolidated sandstone is of great significance for sand control design.By studying the shortcomings of the finite element method in sand production prediction and the research progress of the current discrete element method in sand production prediction of unconsolidated sandstone,it is proposed to use the equivalent plastic strain of the circular hole in the well bore and combine the characteristics of the discrete element method to predict sand production.The results show that the discrete element method makes the numerical simulation accuracy of unconsolidated sandstone reservoir in sand production prediction further improved,and the sand production behavior of unconsolidated sandstone reservoir can be observed from the microscopic point of view.
