三套一条龙注水工艺流程

THREE SETS OF COORDINATED WATER-INJECTION FlOWSHEETS

一条龙注水工艺流程，是指从水源井或油区来水至注水井口的一系列水质处理注水工艺流程。本文介绍了三套适合不同油藏物性、不同油田规模的注水工艺流程，这三套流程归纳总结了多年来油田注水经验并采用了国内三项最新技术，包括井口高压过滤技术、胶帽密闭隔氧技术和多功能污水处理技术。阐述了三项技术的工作原理、安装流程及应用情况。现场应用证明，三套流程适用性强、效率高、投资少，出口水质可以达到部颁水质标准。

The coordinated water-injection flowsheet means a series of water conditioning flowsheets from water source well or oil processing plant to water injection wellhead. This paper introduces three sets of water injection flowsheets that can be used in different reservoir nature and different oil field scale.These flowsheets summarize the waterflood experiences for many years,and adopt three new techniques such as the wellhead high pressure filtration technology,the closed injection water technology using rubber cap and the waste water treatment technology using DL type multifunction filter. The technical principle,flowsheet installation and field applications are discussed in this paper. Field application results Show that the flowsheets have the advantuges such as better suitability,higher effciency and less investment,and that the outlet water quality can meet the ministerial standard
