Efficient evaluation model of beam pumping unit based on principal component regression analysis. [PDF]
Sci Prog, 2020 The beam pumping unit is widely used in oil fields as an oil extraction machine. However, due to its structural characteristics and the changing conditions of underground reservoirs, there are many factors affecting the efficiency of the beam pumping unit. How to quickly and accurately reflect the inefficient factors, and whether the efficiency of the
