利用超二次离散单元公式和达西流体流动公式,发展了模拟油井出砂的技术。离散单元模型是使用粒子克隆的新技术生成的。离散的元素源和汇允许模拟从初始状态到平衡状态的砂子生产,在平衡状态下,颗粒以相同的速度创建和移除。
Techniques for modeling oil well sand production have been developed using the formulations for superquadric discrete elements and Darcy fluid flow. Discrete element models are generated using the new technique of particle cloning. Discrete element sources and sinks allow simulation of sand production from the initiaI state through the transition to an equilibrium state where particles are created and removed at the same rate.
