It can be appreciated that, under different construction conditions, the first fracturing pump 100 generally needs to be matched with corresponding output power to ensure the operation efficiency of the first fracturing pump 100, so that the present invention can realize the selection of multiple driving modes through the control device 400, thereby being better adapted to different working conditions, and compared with a single driving mode in the related art, the present invention has a wider application range. Further, the output power of the first fracturing pump 100 includes a first output power, a second output power and a third output power, which sequentially increase in power, when the first fracturing pump 100 is operated at the first output power, the control device 400 controls the electric driving unit 300 to operate so that the first fracturing pump 100 can perform fracturing under a low power condition, when the first fracturing pump 100 is operated at the second output power, the control device 400 controls the mechanical driving unit 200 to operate so that the first fracturing pump 100 can perform fracturing under a normal condition, and when the first fracturing pump 100 is operated at the third output power, the control device 400 controls both driving units to operate simultaneously so that the first fracturing pump 100 can operate under a high power condition so that the driving device can meet the power requirement of the first fracturing pump 100.
