| 摘 要： | 文留油田产出水矿化度高 ,所含成分具有强腐蚀、结垢倾向 ,储层具有中强水敏性 ,要求注入水质的指标高 ,所以必须通过完善注水工艺流程和加入高效水处理药剂进行水质改性。改性后的水质成分发生了很大变化 ,和地层水有较好的配伍性 ,注水井注水状况好转 ,水驱动用储量增加 ,对提高采收率产生了积极的影响

| Abstract: | The water produced from Wenliu oilfield has high salinity and can easily scale and cause corrosion and the formation of this oilfield has serious water sensitivity. The technical process of water injection must be perfected and effective agents must be used to satisfy the high quality of water injected. The results show that a great componential change occurred in the water and it has a better compatibility with formation water. Injection conditions also turned better and the waterflooding reserves increased. And this has effectively influenced the enhancement of oil recovery. |
