Example Embodiment
[0055] In order to make the technical means, the creation characteristics, the purpose and efficacy of the present invention are readily understood, and the present invention is further clarified in conjunction with the specific embodiments.
[0056] Under more than 20 oil well wells in the oil field site, when the number of types of working conditions is increased, the shape of the function of different working conditions is extremely similar, and the identification difficulty has increased, so there is an algorithm model with powerful learning ability. To learn the subtle difference between the function maps of different working conditions.
[0057] The demonstration drawing data collected by the oil field production site is a sequence of a stroke dome load Y (KN) and displacement x (m), with 120 or 240 data points, and determines the underlying working conditions according to the illustrative drawing drawn. The pump depth of different oil wells, there is a difference in stroke,...
