处理污水是油田生产中的一项重要任务。本文介绍了可编程序控制器在油田污水高效处理系统中的应用。采用可编程控制器（PIC）代替引进设备中的专用控制器，经过近2年的试运行证明，系统运行可靠，在工艺方面和控制方面均达到了国外同类产品的技术指标，而国产设备的价格却不到引进设备的四分之一。
Sewage treatment is an important task in oilfield production. This paper introduces the application of programmable logic controller in oilfield sewage treatment system. The use of programmable logic controller (PIC) instead of the introduction of special controller equipment, after nearly 2 years of trial operation proved that the system is reliable, in terms of technology and control have reached the technical indicators of similar foreign products, and domestic equipment The price is less than a quarter of the imported equipment.
