    • An apparatus (10) for treating a fluid to be injected into a subterranean hydrocarbon-bearing formation comprises a desalination system (12) having a fluid inlet (16) for receiving a first feed fluid (18) and a first fluid outlet (22) for delivering a first product fluid (20). The apparatus (10) also includes a selective ionic species removal plant (30) having a fluid inlet (36) for receiving a second feed fluid (34) and a fluid outlet (40) for delivering a second product fluid (38), wherein the second product fluid (38) has a preferred ionic concentration. A mixer (46) is provided for mixing at least a portion of the first product fluid (20) and at least a portion of the second product fluid (38) to provide a third or injection product fluid (48). Accordingly, injection fluid can be created which has a preferred ionic concentration suitable for injecting into a well (28).
    • 一种用于处理待注入地下含烃地层的流体的设备(10)包括具有用于接收第一进料流体(18)和第一流体出口(22)的流体入口(16)的脱盐系统(12) 用于输送第一产品流体(20)。 装置(10)还包括选择性离子物质去除装置(30),其具有用于接收第二进料流体(34)的流体入口(36)和用于输送第二产物流体(38)的流体出口(40),其中 第二产物流体(38)具有优选的离子浓度。 提供混合器(46),用于混合第一产品流体(20)的至少一部分和第二产品流体(38)的至少一部分,以提供第三或注入产品流体(48)。 因此,可以产生具有适合于注入井(28)的优选离子浓度的注入流体。
