| 摘 要： | 三元复合驱具有良好的驱油效果,比水驱可提高采收率20%以上。但由于强碱化学剂的注入,使三元复合驱注采系统产生了严重的结垢现象,影响了油田生产的正常运行。对大庆油田三元复合驱的代表性垢样进行了成分分析,结果表明,三元复合驱结垢物的主要成分为钙镁碳酸盐、硅酸盐、管线腐蚀产物和有机质,且结垢遵循以下规律:采出井同一部位,随着时间的变化碳酸盐含量逐渐降低,硅酸盐含量增加;同一时间,从井口到井底,碳酸盐含量降低,硅酸盐含量增加。根据结垢特点提出了油田防垢除垢的可行性建议。 |

| Abstract: | Alkali-surfactant-polymer (ASP) flooding is of better effect for oil displacement than water flooding by EOR of over 20%. Because of the injection of alkali,the injection-production system by ASP flooding process is normally impacted by serious scaling of the wells,which is unfavorable for normal production of a field. This paper analyzes the representative scaling sample from ASP flooding in Daqing oil field. The result shows that the main components of the scaling are calcium and magnesium carbonates,sili... |
