摘 要: | 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。

Abstract: | 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... |
