摘　　要：为了认识兴城气田储层开发过程中可能伤害储层的一些因素及提高气田的采收率,对兴城气田储层敏感性进行了实验评价。在研究其岩石性质及矿物成分特征的基础上借助岩心分析,通过模拟地层水对岩心的驱替实验,对兴城气田主力开发层营四段和营一段气层储层的速敏性、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,无碱敏现象。In order to found out some potential factors that may damage the reservoirs and to improve the recovery ratio during gas reservoir development in Xingcheng Gas Field, the experimental evaluation has been made for reservoir sensitivity. Based on the rock properties and mineral composition characteristics, the speed sensitivity, water sensitivity, salt sensitivity, alkali sensitivity and acid sensitivity of reservoirs in the fourth and the first sections of Yingcheng Formation are studied in Xingcheng Gas Field through a core displacement test simulating formation water. The study results show that the reservoir damage is mainly the effects of medium and slightly high water sensitivity and medium salt sensitivity. The effects of medium and slightly weak alkali sensitivity and speed sensitivity have a little damage. There is no alkali sensitivity phenomenon.
