樊家油田樊4块水源水与储层配伍性研究

为了优选适合樊家油田樊4块储层的注水水源，室内采用静态分析与动态流动实验相结合的手段，对明化镇组水和东营组水2种水源水与储层的配伍性进行了研究。结果表明，樊4块的2种水源水与储层均不配伍，均存在结垢伤害，垢物成分主要为碳酸盐，明化镇组水源水对储层的主要伤害类型为强水敏伤害，东营组水源水对储层的主要伤害类型为中等水敏伤害和悬浮颗粒的堵塞。比较2种水源水对樊4块储层的伤害程度，东营组水对储层的伤害相对较轻，可以优选作为樊4块储层的注水水源。

Study of compatibility between source water and reservoir rocks in Fan 4 bloek of Fanjia Oilfield

Compatibility of source water from Minghuazhen and Dongying Formation with the reservoirs are studied by static analysis and dynamic flow experiment so as to optimize the injected water source for Fan 4 block in Fanjia Oilfield.The study shows that the source water for Fan 4 block are not compatible with the reservoirs,which results in scaling damage.The main component of the scale is carbonate.The type of the main damage to the reservoir by Minghuazhen source water is strong water sensitivity,while that by Dongying source water is medium water sensitivity and plugging of suspended particles.Dongying source water can be used as the injected water for Fan 4 block because of its weaker damage to the reservoir.
