Sand Production Modeling Using Superquadric Discrete Elements and Coupling of Fluid Flow and Particle Motion

摘要

Techniques for modeling oil well sand production have been developed using the formulations for superquadric discrete elements and Darcy fluid flow. Discrete eleement models are generated using the new technique of particle cloning. Discrete element sources and sinks allow simulation of sand production from the initial state through the transition to an equilibrium state where particles are created and removed at the same rate.
