浅谈注入水与地层水的配伍性

Discussion on compatibility between formation water and injection water

随着对油田不断地开发,地层能量不断地降低,很多油田采取注水来补出地层能量。如果注入水与地层水配伍性很差或不配,会对储层造成损害,严重影响经济效益。因此,对配伍性的研究很关键。本文先对注入水水质及与地层水结垢进行了分析,然后对注入水与地层水配伍性进行了研究,最后提出对伤害的预防及解堵的措施。

With the constant oilfield production and declining formation energy,injection water is often used to fill out theformation energy in a lot of oilfields.If the compatibility between injected water and formation water is poor or bad,the reservoirwill be harmed and further the economic benefits will be seriously impacted.Therefore,it is important to research the compatibilitybetween them.In this paper,the quality of injection water and the scaling of formation water are analyzed firstly,and then thecompatibility between injected water and formation water is studied,finally,the harm prevention and plugging removal measures areput forward.
