摘　　要：为了认识乌南油田储层开发过程中可能伤害储层的一些因素,对乌南油田储层敏感性进行了实验评价。通过对岩心的驱替实验,对乌南油田储层的速敏性、水敏性、盐敏性、碱敏性及酸敏性等进行了实验研究。研究结果表明该储层主要伤害为中偏强水敏,中等的盐敏效应,碱敏和速敏效为中偏弱,伤害不大。In order to understand the development process Wunan of reservoir formation damage factors,There were experimental evaluation within Wunan Oilfield sensitivity.Through the core of the displacement experiment,the speed of Wunan sensitivity of reservoir,water sensitivity,salt sensitivity,alkaline and acid sensitivity,sensitivity,etc.was studied.The results show that the reservoir is partial damage to the water sensitivity,secondary effects of salt sensitivity,sensitivity and speed-sensitive base effect as the weak.
