针对油田偏心注水工艺过程繁琐、复杂的问题,提出了一种基于PIC16F877A的分层注水流量智能测调系统的设计方案,介绍了系统的工作原理及软、硬件设计。该系统采用模糊控制方法对注水流量进行智能调节和控制,通过串行通信接口实现上、下位机的通信,具有自动调节各分层的注水配注量及远程监测功能。试验结果表明,该系统运行稳定,流量调节响应速度快,调节精度高、误差小,具有较强的可靠性及抗干扰能力。

In order to solve problems of inconvenience and complexity of eccentric injection of oilfields,a design scheme of intelligent measuring and adjusting system for zonal injection flow based on PIC16F877A was proposed and working principle and design of software and hardware of the system were introduced.Fuzzy control method is used in the system to adjust and control injection flow intelligently and serial port is used to realize communication between upper and lower computers.The system has functions of automatic adjustment of each zonal injection flow and remote monitoring.The test result showed the system has stable running,quick respond speed of flow adjustment,high precision and small error of adjustment with high reliability and anti-interference ability.
