摘　　要：介绍了中原油田沙三段储层的基本物性,指出了粘土矿物的主要含量及分布状况。根据粘土矿物引起储层敏感性的特点,预测了该储层潜在的伤害类型。通过岩心流动实验分析了该储层潜在的伤害类型及伤害程度,并根据粘土矿物的成分具体指出了产生伤害的原因。结果表明,该储层存在中等伤害程度的速敏,存在弱盐敏伤害,碱敏伤害呈中等程度。最后根据评价结果对该油田的开发工作提出了具体的建议。The paper introduced the basic physical properties of the s 3 reservoir in Zhongyuan Oilfield.It shows the main clay mineral and it's distribution.According to the sensitivity characteristics of reservoir caused by clay minerals,the types of potential injuries are predicted,and the types and the degree of damage are analyzed by doing core flow experiments,and the reasons for damage has been pointed out based on the composition of clay minerals.The results show that the degree of speed-sensitive damage is moderate,the level of salt sensitivity damage is weak and the alkali sensitivity damage is moderate.Finally,according to results of the evaluation of the oil field,specific recommendations are made for development work.
