| 摘 要： | 为了模拟油层出砂对地层的伤害，在扩散-对流方程的基础上，建立了一个关于多孔介质内微粒启动、运移、堵塞的数学模型，在孔隙级别上揭示了微粒在地层伤害中的作用。应用有限差分法对所建模型进行了数值求解，结果表明：该模型能够很好的模拟和预测由油层出砂造成的油层伤害过程及该类油层近井地带不同开发阶段的伤害程度，对于油层的评价、增产措施的实施等具有重要意义。

| Abstract: | To smulate the damage of sanding to the oil formation, a mathematical model describing the fines mobilization, migration and clogging in porous media was established based on the convection-diffusion equation. The model illustrated the formation damage on the pore scale. The finite difference method was employed to solve the model. The result shows that the model is adaptable to simulating or predicting the process of oil formation damage caused by sanding and is an efficient calculator for simulating the damage process near borehole in different development periods. |
