摘　　要：对刘庄油田在注水开发过程中储集层敏感性、注入水水质及结垢对储集层的损害进行了研究,结果表明储集层敏感性损害主要有水敏、碱敏及应力敏感性损害。为达到较好的注水开发效果,建议控制注水压差和采油压差,同时要重视和强调注水过程中的储集层保护。Formation damage caused by reservoir sensitivity, quality of injection water and scale in the process of waterflooding in Liuzhuang low permeability oilfield is studied, the result shows that the sensitivity damage includes water sensitivity, alkali sensitivity and stress sensitivity. It is proposed that to achieve better waterflooding effect, the pressure differentials of waterflooding and production shall be controlled and formation protection shall be focused on and emphasized.
