渤南义37块低渗油田注入水改性储层保护研究

针对低渗透油田注水水质引起注水系统结垢和油藏伤害问题，以渤南油田义37区块为研究对象，结合现场实际情况全面分析了该区块注入水储层伤害因素，通过室内实验提出了注入水水质改性和储层保护的方法。研究表明，应用强酸性苯乙烯系阳树脂对注入水进行水质改性，并在改性水中加入优选的2%MGPR破乳剂、6o%XCFP防膨剂可使注水防垢、防乳化、防膨一次解决，为该区块有效注水开发提供了技术保障。

Injection Water Quality Adjustment and Reservior Protection Research of Low Permeability Oil Field In Yi-37 Block Bonan Oil Field

In view of the scaling in injection water system and reservior damage caused by injection water quality in low permeability oil field,the paper analyzed damage elements with injection water,proposed a method to adjust injection water quality and protect reservior.It was a way which used highly acid positive styrene resin to adjust water quality meantime added 2% MGPR demulsifying agent and 6% XCFP antiswelling agent.It could achieve anti-scaling,anti-emulsification and anti-expanding of clay at the same tim...
