Plc In The Process Of Oil Transfer Water

With the oil-field development high contains water the later period, the oil-field development difficulty increases, as well as to controls the enhancement which, the survey precision, timeliness, the communication function and so on various aspects requests, each station, storehouse technological process more complex, uses the manual monitoring and the conventional measuring appliance monitoring has been very difficult to satisfy the production request. But transfers the oil to put the water station is the oil field production important link, how appropriately chooses, the design safely reliable, the data display accurate, the ease of operation nimble, is advantageous for the maintenance computer observation and control system, guaranteed the oil field measuring appliance, the microcomputer systematic security, is accurate, the steady movement, the optimized control, the realization safety in production and the energy conservation falls consumes, saves the manpower, the physical resource, enhances the working efficiency, and the production management level, is we at present in an oil field production important topic.The present paper union oil field transfers the oil to put the water station production course actual situation, as well as the computer, the PLC technology in the oil field application, the development present situation, researched the microcomputer measure and control system of design plan, examines the measuring appliance the shaping, signal transmission processing, the design of the software, the choice of the hardware and realization.This paper introduced the extension oil puts the water station the PLC control system, uses labor controlling machine PC to take on the position machine, to the entire technological process realization supervise and control with manage, PLC takes the lower position machine, realization electronic contact control, PID control. Like this even if once on the position machine breaks down, also does not affect the lower position machine control, causes the PLC system the production control function and the information management function merges into one organic whole, the realization"the danger is dispersible, control centralism" goal.This paper studies the hillock PLC control system that the south I-I gathers station to transfer the oil to turn on the water, has put the operation since last year, data acquisition accurate, systems control stable, movement safe reliable, the system provides direct-viewing for the post operator has been convenient, the content rich man-machine contact surface, enhanced the working efficiency, the management level, the economic efficiency, has guaranteed the safety in production.
