Analysis of the migration patterns of sand particles below the screw pump in wells based on experiments and numerical simulations

To enhance the sand particle migration capability in shale oil well progressive cavity pumps, it is essential to analyze the particle migration patterns in perforated well sections. A coupled Computational Fluid Dynamics and Discrete Element Method was employed to numerically simulate sand flow char...
