| 摘 要： | 针对劳山油田W110井区长6储层低孔、特低渗的特征,通过系统的岩心流动实验,评价了储层敏感程度。研究结果表明:W110井区长6储层整体存在中等盐敏、中等偏弱酸敏和弱水敏、强碱敏和无速敏的特征。储层敏感性相对较弱,对研究区开采影响较大的为酸敏和碱敏,中等偏弱的酸敏使得研究区可适当进行酸化改造,强碱敏导致在注入液时需注意注入液pH值对储层的伤害。

| Abstract: | In view of the characteristics of Chang 6 reservoir of W110 block in Laoshan oilfield, core flow experiment has been carried out to analysis the sensitivity characteristics. The study result shows that the reservoirs in the Chang 6 member in W110 block is generally medium salt sensitive, medium to weak acid sensitive and weak water sensi- tive, strong alkali sensitive, not velocity sensitive. Reservoir sensitivity is relatively weak, acid sensitive and alkali sensitive are the important influence on drilling. Medium to weak acid sensitivity makes the study area can be appro- priately acidizing, strong alkali sensitivity resulted in the injected liquid should pay attention to when injected into the liquid pH damage to reservoir. |
