摘要

对研制成功的CQ-1和NS-916等难溶垢的清除剂做了室内评价和现场应用试验。在50℃时,CQ-1对油田钙垢的清除效果优于进口产品S-466;在70℃时,NS-916对油田钡垢的清除效果接近于S-466。现场实际清洗结果表明,CQ-1和NS-916对油田集输系统难溶垢的处理效果良好,该清洗技术已成为油田开发后期的一项实用技术。

Abstract

This paper introduces the CQ-1 and NS-916 type cleaning agent of infusible scale.Their indoor evaluation and field application results show that the cleaning effectiveness to calcium scale of CQ-1 is better than that of S-466 in 5℃,which is a import product,and that the cleaning effectiveness to baria scale of NS-916 is close to that of S466.CQ-1 and NS-916 have good results for cleaning the infusible scale in gathering station of oil field.It is a practical technique for the later-period oil field development.
