摘　　要：根据台兴油田的储层和流体特征,分析了注水水质对储层的伤害因素和机理。水敏伤害和注入水与地层水不配伍产生沉淀和结垢是吸水能力下降的主要因素。及时、定时、定量投加经济高效的防膨剂和防垢剂是提高水质的关键。The factors and mechanisms of damages of injection water quality to reservoirs are analysed, based on the characteristics of reservoirs and fluids from Taixing oilfield. It is considered that water absorptivity is mainly affected by watersensitive damages and precipitation and scaling caused by the incompatibility between injection and formation waters. The key to improved water quality lies in economic and effective autiexpander and antiscale being dosed timely, regularly and quantitatively.
