Title
MECHANISM STUDY OF PARTICULATE MIGRATION USING MICROMODEL EXPERIMENT
摘要
颗粒运移在地层损害中占很大比例。研究颗粒在多孔介质内的运移机理有助于用数学的方法更加真实地模拟颗粒在多孔介质内的运移堵塞规律,以便更加清楚地认识颗粒损害机理。本文用微观模型可见技术研究了水动力学条件及颗粒自身性质对颗粒运动的影响,得出了颗粒运移的一些规律。
Abstract
The study of porticle movement,which takes a great portions in formation damage,is useful to present more realistic mathematical model for particulate migration in porous media and to recognize the damage mechanism of particulate more clearly.The micromodel visual technique is applied in this article to studying the effects of the dynamics condition of water flow and the particles’ property on the movement of particles.
