摘　　要：针对目前国内外油田加药装置系统无法动态跟踪加药管道流量、成本高、劳动强度大、无法进行多点监控及协调控制,造成水、电及人力的浪费等现状;采用西门子S7-200PLC自动检测输油/气管流量,根据设定药液的配比浓度,实现自动配药、自动搅拌、按设定的ppm比例采用模糊自适应PID控制技术实现精确加药的自动控制系统,使注入量误差小于0.3L/h;同时基于以太网实现远程控制,提高了油田生产效率及管理水平;目前,该系统已应用于全国多家著名石油企业,反映良好。In view of the current domestic and foreign oilfield dosing device system to dynamic tracking dosing pipeline flow, high cost, high labor intensity, can not be multi--point monitoring and control. Adopts Siemens S7--200 PLC automatic detection of oil/gas flow, ac- cording to the set liquid concentration, realize automatic dispensing, automatic mixing, by setting the PPM proportional fuzzy adaptive PID control technology to make injection quantity error is less than 0. 3 L/h and to realize precise dosing of the automatic control system based on Ethernet Remote control; at the same time, improves the production efficiency and the management level of oil field. At present, the system has been applied to several well--known national oil comoanies, reflecting is good.
