摘要
以烯类单体为主要原料,采用水溶液聚合的方法,合成了新型两性离子聚合物钻井液体降粘剂GCH-11。考察了GCH-11在不同钻井液体系的降粘效果和抗盐性能。结果表明,GCH-11在膨润土钻井液、聚合物钻井液及高密度聚合物钻井液中的降粘效果优于GD-18和XY-27,是高密度聚合物钻井液的理想降粘剂。
This paper gives the preparation and evaluation of a new amphoteric graft copolymer named GCH -11. It' s shown than the effect of GCH - 11 is better than those of XY - 27 and GD - 18, and it can be widely used in fresh - water mud, salt - water mud and high density mud.
