[0069] In order to verify the effect of the learning estimation method of a kind of pumping unit dynamometer diagram of the present invention, carry out following experiment:
[0070] The measured data of the pumping units of 4 oil wells numbered HD91334, HD91353, HD91354 and HD91409 were randomly selected for experiments to form 4 sets of experimental sample data, in which the first 50 data records were selected as the learning data for each set of sample data, and the 100th data records as test data.
[0071] The experimental results are shown in Figure 3, where the dotted line represents the estimated curve and the solid line represents the measured curve. It can be seen from the figure that although the dynamometer curves corresponding to the four groups of experiments have different shapes, the estimated curves can fit the measured curves well.
[0072] The software platform for the 4 groups of experiments is Matlab-R2013a, and the hardware platform is a PC with 2.66GHz ...
