靖一联采出水处理及回注工艺技术研究与应用

Produced water treatment and reinjection technology research and application in the Jingyi union station

主要针对靖一联絮凝罐+精细过滤处理工艺处理后水质达不到回注标准的现状,借鉴油一联微生物处理的成功经验,通过室内菌种筛选,优选出了适合靖一联采出水的微生物菌群,并在现场进行了微生物处理工艺改造,使靖一联采出水处理水质得到了明显改善,达到了油田采出水的回注要求,实现了靖一联全部采出水的有效回注,节约了大量的清水资源和运行费用。

This article will focus Jingyi union station flocculation tank ＋ fine filtration process the treated water quality standards fail to note the status back to learn from Youyi union station to a successful experience of microbial treatment,by laboratory screening,selection out of a joint for Jingyi union station produced water microflora,and in the field of microbial treatment technology to a joint recovery Jingyi union station water quality has been improved significantly,reaching the oilfield produced water re -injection requirements,achieve all produced water of Jing 1 union station an effective reinjection,saving a lot of fresh water resources and running costs.
