活性乳化聚丙烯酰胺驱油剂的研究

Study on Active Emulsified Polyacrylamide Oil Displacement Agent

活性乳化聚丙烯酰胺驱油剂是一种兼具乳化和增黏双重功效的新型驱油剂,能在中低渗高含水油藏中发挥较好的驱油作用。以丙烯酰胺为主链,选用具有亲油结构的疏水功能单体和具有亲水、亲油作用的两种表面活性剂,采用水溶液聚合和复合氧化还原引发体系进行胶束共聚,合成出具有活性乳化效果的聚丙烯酰胺,并对其性能进行评价。

Active emulsified polyacrylamide oil displacement agent is a new type of oil displacement agent with both emulsification and viscosity enhancement,which can play a good role in oil displacement of medium and low permeability and high water cut reservoirs.In this paper,acrylamide was used as the main chain,hydrophobic functional monomer with lipophilic structure and two kinds of surfactants with hydrophilic and lipophilic effect were selected to synthesize polyacrylamide with active emulsification effect by micellar polymerization with aqueous solution polymerization and compound redox initiator system,and its properties were evaluated.
