注入水中固相颗粒对地层的伤害分析

中高渗透油藏在注入污水过程中，常常由于固体颗粒的堵塞而造成油层污染。为选择合适的水质，通过对注入水中固体颗粒的粒度、含量分析、伤害机理评价及室内伤害试验，指出了固相颗粒对不同参数储层的伤害程度，确定了适合本区注入水的水质指标。

Analysis on Formation Damage by the Solid Particle within the Injected Water

The formation will usually be polluted by the jam of solid particle in the course of polluted water injection in medium high permeability reservoir.In order to select proper water quality,by the analysis of particle size and proportion of the solid particle,evaluation of damage mechanism and damage experiment in the laboratory,this article points out the damage degree made by solid particle in different parameter reservoir,and confirms the origin proper index of water quality.
