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.
