摘　　要：针对川北柏垭区块大安寨一亚段储层岩石孔隙结构差,属于致密储层的特点,对大一亚段的速敏性、水敏性、盐敏性、碱敏性和酸敏性进行了储层敏感性试验。结果表明,该段储层主要表现为弱速敏、中等偏强水敏、中等偏弱盐敏、无酸敏和中强碱敏。因此,在川北柏垭区块大安寨一亚段储层开发生产过程中应重点防治储层水敏性、盐敏性及碱敏性对储层带来的伤害,从而避免更大的经济损失。Based on the characteristics of Da＇anzhai-1 submember in Baiya block of North Sichuan, the reservoir sensitivity test of this area was carried out to analyze Da＇anzhai-1 submember speed sensitivity, water sensitivity, salt sensitivity, alkali sensitivity and acid sensitivity. The results show that the reservoir is weak speed sensitivity, moderate to strong water sensitivity, moderate to weak salt sensitivity, moderate to strong alkali sensitivity and no acid sensitivity. Therefore, in order to avoid greater economic loss, it is important to prevent the reservoir damage caused by the water sensitivity, salt sensitivity and alkali sensitivity in the reservoir development in Da＇anzhai-1 submember in Baiya block of north Sichuan.
