摘　　要：储层中微粒运移是储层损害的主要因素之一。利用速敏、正反向流动两种岩心流动实验可以直观判断储层中微粒运移,速敏实验是判断储层岩心微粒运移状况的基本方法。但单独运用速敏实验并不可靠,需要以正反向流动实验及储层相关地质资料为辅助加以分析判断。根据正反向流动实验曲线中渗透率的变化,可判断微粒运移。通过储层岩矿成分分析及胶结状态的观察结果等储层地质资料的分析,可以预测或验证岩心微粒运移现象的发生状况。The particle migration in reservoir is one of the main reservoir-damaging factors. By using experiments of velocity sensibility and 2 opposite (positive and negative) directions flowing in 2 types of core fluid flow, the particle migration situation in reservoir may be audio-visually judged. The velocity sensibility experiment is the basic method of judging particle migration situation in reservoir core, but its single-handed utilization is not reliable, necessarily aided by 2 opposite directions flowing experiment, and relevant geologic data of reservoir for analysis and judgement. Based on permeability change in 2 opposite directions flowing experiment curves, the particle migration situation may be judged, and through analyzing the results of such reservoir geologic data as reservoir rock and mineral composition analysis and its cementation observation etc. the occurring situation of core particle migration phenomenon may be predicted or verified.
