oil pumping with lever system ground facilities efficiency evaluate method

The method comprises: a) drawing a operating condition graph, and dividing the operating condition graph into four areas which are an area of test parameter under investigation, an area of normal working, an area of low mechanical efficiency, and an area of motor low load and load efficiency; b) determining the location of individual well in the graph: testing the motor running parameter, pumping unit well suspension parameter, and using diagram of work fluidounce metering to fast measure the fluidounce yield; calculating the motor input and output power, motor load rate, pumping unit polished rod power and pumping unit system ground efficiency; filling the obtained motor load rate, pumping unit system ground efficiency data into the ground electromechanical system operating condition graph.
