摘要
针对稠油净化水回注稀油井区的可行性研究。实验结果表明:稠油净化水水质较好,各项指标均满足注水指标要求;稳定性好,不会引起注水系统和原油储层结垢;对储层伤害性弱,有利于保护原油储层;水温较高,可降低原油粘度,改善原油流动性,利于提高采收率。稠油净化水用于回注稀油油田,可大量减少净化水的排放量,使其得到资源化利用,减少了对环境的污染。
Feasibility study for the reinjection of purified water from heavy oil into thin oil wells.The experimental results show that the quality of purified water from heavy oil is good,and all indicators meet the requirements of water injection indicators;it has good stability and will not cause scaling in the water injection system and crude oil reservoir;it is weak to the reservoir and is beneficial to the protection of the crude oil reservoir.Higher water temperature can reduce the viscosity of crude oil,improve the fluidity of crude oil,and help increase oil recovery.The heavy oil purified water is used to reinject the thin oil field,which can greatly reduce the discharge of purified water,make it resourceful,and reduce environmental pollution.
