Automatic Added Agent System Design And Study In The Oil Field

It needs dosing processing in gatheirng and transporting crude oil because its specialnature. The key to guarantee the normal production is dosing reasonably. Obviously it isdifficult to grasp the dosage because numerous subordinate well stations, unstable oil amount,larger changing of lfow in a certain peirod and drug concentration which is influenced bytemperature and pressure. In addition, pressure is also the important parameters in productionprocess. Masteirng relevant technical parameters is favor of achieving production optimumcontrol. While artificial completing and setting a ifxed value are the major ways to dose indomestic oilifeld metering pump at present. The dosage can’t dynamic tracking crude oil lfowand it needs24hours on duty. It caused intensive labor and relative higher cost. Moreimportant, it is also unable to real time monitor some important parameters.According to domestic backward oil dosing mode currently, this paper puts forward an oilwell site dosing system research in order to solve energy consumption, human consumption,no monitor of technical parameters and dosing precision and other problems. The systemwhich accords with change of crude lfux，temperature and pipeline pressure can controlautomatically dose.The article has set up mathematical model of the Added Agent System jet device anddesigned equipment structure. Oil well site automatic dosing system hardware and automaticcontrol system are designed by PLC interface technology. It realizes digital tube display，metering pump control and centirfugal pump control. System communication mode andsystem design pirnciple are confirmed through analyzing and contrasting variouscommunication modes，which is based on GPRS communication technology in oilfield remotemonitoirng system overall frame and main fixncitons*...
