The Research And Development On The Teaching Model Machine System Of The Pumping Unit

Pumping units are drives on the ground of rod pumping system in oil field．Theirquantity is over ninety percens of the whole quantity of the equipments of oil extraction in oilfield．Among these pumping units，the use of beam pumping units is the broadest．To solvethe problems of abstract classroom teaching, physical security of practice in oil field, highcost and long time of practice, and so on, an experimental teaching platform for the pumpingunit teaching model has been developed On the basis of analysis to the pumping unit marketand technical level，do the research of optimal design of a kind of intelligent belt pumpingunit，and finish the design of the pumping unit．By analyzing the work theory of beam-pumping unit，a beam pumping unit model isestablished．The kinetic characteristic and dynamic characteristic simulation have beenmade．According to mechanical system dynamics principle，beam sucker rod pumping systemis simplified to an equivalent model．It consists of beam pumping units, pumps, air supplysystem, fluid supply system, indicator, an experimental table, etc. Design of oil pumpingmachine instruction model control system software and hardware detection system It candemonstrate the operating principle of the beam pumping un it and the pump，Productionprocess of indicator diagram，judge the troubles of oil weel by an indicator diagram, train toclean out operation, contrast the efficiency and distinguishing feature of three beam pumpingun its, analyze the energy saving of production, and look for a effective way to raise theefficiency about the oil production.The pumping unit teaching model experimental teaching platform makes the practice gofrom the well site to the lab, and it is a good assistant in experimental teaching Theexperiment platform which was passed actual test and is being used now is designed according to the actual field status．Good effect will be acquired if it is used for eitherpractical teaching or research.
