摘要
应用岩心流动试验评价了濮城油田南区沙二下亚段储层的敏感性,分析了储层潜在伤害因素、伤害机理及伤害程度。结果表明,该油藏的速敏损害程度弱,水敏损害程度弱,同时具有弱至中等偏弱碱敏和弱酸敏效应。并根据评价结果对油田开发工作提出了具体建议。
By using core displacement test,the reservoir sensitivity in the lower member of Es2 in the south of Pucheng Oilfield was evaluated,the potential damage factor,its mechanism and degree were analyzed.The results show that the fast sensitive damage level is low,water sensitive damage level is weak,also it has mid-low alkali sensitivity and weak acidic effect.Based on the study result suggestions are put forward for the oilfield development.
