摘　　要：精细注水对于提升吴起柳沟区块油藏开发效益意义重大。由于油藏对于水质要求不一,由于油田注入水成垢离子类型相差很大,其结垢倾向差别明显,这会直接影响注水效益。基于此,文章通过对柳沟注水项目区注入水与地层水的化学成分进行分析,预测结垢趋势,并据此对注入水和地层水之间配伍性以及阻垢剂用量进行了针对性优化,从而有效保障了注水质量。Fine water injection is of great significance for improving the development efficiency of the Liugou block oil reservoir in Wuqi.Due to the varying requirements for water quality in oil reservoirs and the significant differences in the types of scaling ions in injected water,the tendency for scaling varies significantly,which directly affects the efficiency of water injection.Based on this,the article analyzes the chemical composition of injected water and formation water in the Liugou water injection project area,predicts the trend of scaling,and based on this,optimizes the compatibility between injected water and formation water as well as the dosage of scale inhibitors,effectively ensuring the quality of water injection.
