摘要: 梳形聚丙烯酰胺的现场应用结果表明,在相同条件下,梳形聚丙烯酰胺比大庆产聚丙烯酰胺的增粘能力高58%~81%,比日本三菱公司产MO4000的增粘能力高22%~70%;其驱油效果比聚丙烯酰胺约提高一倍,降低聚合物用量30%以上.梳形聚丙烯酰胺在油田聚合物驱、三元复合驱和深部调驱中已取得很好的经济、社会和环境效益,成为油田新一代的高效驱油剂和调剖剂.

Abstract: The in-situ application results of comb-shape polyacrylamide showed that the comb-shape polyacrylamide can increase the viscosity value of 58 percent to 81 percent more than that of the ordinary Daqing polyacrylamide,and 22 percent to 70 percent more than that of the ordinary polyacrylamide MO-4000 produced by Japan,under the same conditions.The oil displacement efficiency of comb-shape polyacrylamide can increase by two times compared with that of the ordinary polyacrylamide.At the same time,it can decrease the polymer dosage by 30 percent more than the ordinary polyacrylamide.The excellent economy,social and environment benefits of comb-shape polyacrylamide for polymer flooding,alkaline-surfactant-polymer flooding and cross-linking polymer flooding have been achieved.It has become an excellent high-efficiency oil displacement agent and profile modification agent for oilfield exploitation.

Key words: oil displacement agent, comb-shape polyacrylamide, salt-resistant polymer, polymer flooding, alkaline-surfactant-polymer flooding, profile modification agent, application effectiveness
