The Measuring and Controlling System of Mechanical Recovery Laboratory

The hydraulic transfer, sensor and computer techniques are applied in the measuring and controlling system of mechanical recovery laboratory. The conditions of pumping well and well pumping u-nit in processing of mechanical recovery can be simulated in the laboratory. By controlling of the motion of the unit and the conditions of the well, the law of the motion of the unit and the oil production can be measured at the same time in order to study the conditons of mechanical recovery and the efficiency of oil production. The technique of computer controll and measurement has good applying prospects in the petroleum industry. Modifying the controlled parameters on line is near real-time and of good controlling results. The efficiencies of oil production under several motion laws of the unit are compared, which can supply a reference method for raising the efficiency of oil production
