摘　　要：共聚物堵水剂以其"堵水不堵油"的良好油水选择性越来越受国内外研究者的青睐。通过水溶液共聚法合成得到的长链聚合物分子类堵水剂,依靠聚合物分子链在水相中伸展、在油相中收缩,形成对水相的"拖曳"作用,降低水相渗透率。该体系具有较高的强度和吸水性能,用于油井深部堵水,可获得良好效果。Polymers are very popular in studying of new water-shut off gels because they can plug water well more than oil.Plugging agent with long chain polymer can be obtained through the aqueous solution copolymerization synthetic.It reduces the water phase permeability with water phase ＂drag＂ effect by means of polymer molecular chain in water phase stretch and in the oil phase contraction.This gels has higher strength and water absorption performance.It may obtain good results for oil well deep water plugging.
