摘　　要：设计用于区分认识储层水敏伤害与水锁伤害的综合性实验,通过岩心矿物分析、微观形貌观察、润湿性测定与孔喉分布特征对储层潜在水敏与水锁程度进行评判;开展水锁伤害与水敏伤害岩心流动实验,评价储层伤害程度。综合分析潜在损害因素与实际实验结果,区分水敏与水锁伤害的实际影响权重。结果表明,岩心矿物组分、微观结构形貌、润湿性与孔喉分布特征分析是准确区分认识水敏与水锁的前提;敏感性实验评价得到的水敏伤害比实际高,储层伤害主控因素是水敏的评判结果往往是片面的,真实主控因素更可能为水锁。该综合实验可为石油工程专业相关课程的实验设置提供借鉴。A comprehensive experiment is designed to distinguish and recognize reservoir water sensitive damage and water lock damage.The potential water sensitivity and water locking degree of the reservoir are evaluated by core minerals,microscopic morphology,wettability and pore throat distribution.We carry out water lock damage and water sensitive damage experiments to evaluate the degree of reservoir damage.Through the comprehensive analysis of potential damage factors and actual experimental results,the actual influence weight of water sensitivity and water lock injury are distinguished.The results show that analysis of core mineral composition,microstructure morphology,wettability and pore throat distribution characteristics is the premise of accurately distinguishing and recognizing water sensitivity and water lock.The water-sensitive damage obtained by the sensitivity test is higher than the actual.The main controlling factor of reservoir damage is water sensitivity,which is often one-sided,and the real main controlling factor is more likely to be water lock.This comprehensive experiment can provide reference for the experiment setting of relevant courses of petroleum engineering.
