The fracturing truck, fracturing hybrid drive system and method of the present invention are described below in conjunction with fig. 1-5.
Referring to fig. 1 to 4, a fracturing hybrid drive system according to an embodiment of the first aspect of the present invention mainly includes: a fracturing pump 100, a hydraulic drive unit 200, an electric drive unit 300, and a controller 400. Wherein the fracturing pump 100 includes a first input 101 and a second input 102; the hydraulic drive unit 200 is connected to the first input 101 of the fracturing pump 100, the hydraulic drive unit 200 being adapted to hydraulically drive the fracturing pump 100; an electric drive unit 300 is connected to the second input 102 of the fracturing pump 100, the electric drive unit 300 being adapted to electrically drive the fracturing pump 100; the controller 400 is configured to control the operation of the hydraulic drive unit 200 and/or the electric drive unit 300 based on the output power of the frac pump 100, implementing a hydraulic drive mode, an electric drive mode, or an electro-hydraulic hybrid drive mode. Therefore, the fracturing hybrid driving system has multiple driving modes and can adapt to multiple different working conditions.
It can be understood that, because the fracturing pump 100 generally needs to be matched with corresponding output power under different construction conditions to ensure the operation efficiency of the fracturing pump 100, the controller 400 can be used for selecting a plurality of driving modes, so that the fracturing pump can be better adapted to different working conditions.
The fracturing hybrid driving system provided by the embodiment of the invention is connected with the first input end 101 of the fracturing pump 100 through the hydraulic driving unit 200, and can hydraulically drive the fracturing pump 100; the fracturing pump 100 may be electrically driven by the electrical drive unit 300 being connected to the second input 102 of the fracturing pump 100; the hydraulic drive mode, the electric drive mode, and the hybrid drive mode may be implemented by the controller 400 controlling the operation of the hydraulic drive unit 200 and/or the electric drive unit 300 based on the output power of the frac pump 100. Therefore, the fracturing pump 100 can realize multiple driving modes of the fracturing pump 100, is suitable for multiple different working conditions, realizes energy conservation and emission reduction, and has the characteristics of simple structure, wide application range, high economy and the like.
According to one embodiment of the invention, the output power of the frac pump 100 includes a first output power and a second output power, the second output power being greater than the first output power; when the fracturing pump 100 operates under the construction condition of relatively low first output power, the hydraulic driving unit 200 can be controlled to operate, and the fracturing is performed under the low-power working condition by adopting a hydraulic driving mode, so that the problems of large vibration, high oil consumption, oil leakage and the like of the hydraulic driving fracturing pump in the high-power fracturing construction in the related art can be well solved; or, when the fracturing pump 100 operates under the first output power working condition, the electric drive unit 300 can be controlled to operate, and the fracturing is performed under the low-power working condition by adopting the electric drive mode, so that the oil consumption can be reduced, the energy conservation and the emission reduction can be realized, and the economy can be improved.
When the fracturing pump 100 operates under the construction condition of relatively high second output power, the hydraulic drive unit 200 and the electric drive unit 300 are controlled to operate together, and when an electro-hydraulic hybrid drive mode is adopted under a high-power working condition, the vibration of the whole fracturing truck can be reduced, the pressure of a hydraulic system of the fracturing truck is reduced, and the risk of oil leakage is reduced.
In other embodiments, an electric drive mode, a hydraulic drive mode or a hybrid drive mode can be selected according to the oil consumption and the electricity consumption, so that the effects of energy conservation and emission reduction are achieved.
It is understood that the present invention does not specifically limit the specific values of the first output power and the second output power, as long as the second output power is ensured to be greater than the first output power. In general, when performing soft geological fracturing, the fracturing pump 100 may be matched to a relatively low first output power, which may be, for example, less than 1500 horsepower of water, at which time the hydraulic drive unit 200 or the electric drive unit 300 may be controlled to operate; when the hard geological fracturing is constructed, the fracturing pump 100 can be matched with a second output power which is relatively high, for example, 1500-2500 water horsepower, and the hydraulic drive unit 200 and the electric drive unit 300 can be controlled to operate together.

According to one embodiment of the present invention, as shown in FIG. 2, a hydraulic drive assembly includes: an oil pump 202 and a hydraulic motor 203, the oil pump 202 being connected to the first engine 201, the hydraulic motor 203 being connected to the oil pump 202 and the first input 101 of the frac pump 100, respectively, in other words, the first engine 201 is connected to the first input 101 of the frac pump 100 via the oil pump 202 and the hydraulic motor 203 in sequence.
According to an embodiment of the present invention, the hydraulic transmission assembly further includes a hydraulic oil tank (not shown in the drawings), and the hydraulic oil tank is connected to the oil pump 202 and the hydraulic motor 203 through oil passages, respectively. Specifically, the first engine 201 drives the oil pump 202 to operate, hydraulic oil in a hydraulic oil tank is sucked into the oil pump 202, the generated pressure oil is pumped into the hydraulic motor 203, under the action of the pressure oil, the hydraulic motor 203 drives the fracturing pump 100 to rotate to achieve fracturing, and the hydraulic motor 203 returns oil to the hydraulic oil tank.

According to the invention, the hydraulic motors 203 are at least two, and the high-power output is distributed by the at least two hydraulic motors 203 together, so that the service life of the whole system can be prolonged on the premise of ensuring the high-power output, and when one hydraulic motor 203 is damaged, the continuous operation of the fracturing pump can be ensured by other hydraulic motors 203, thereby reducing the construction risk.

It will be appreciated that when the electric motor 304 is only one, it is generally necessary to match the high power electric motor to accommodate high power operation, but long runs are prone to burn out, resulting in fracturing job interruptions with job risks. According to the invention, the number of the electric motors 304 is at least two, and the high-power output is distributed by the at least two electric motors 304 together, so that the service life of the whole system can be prolonged on the premise of ensuring the high-power output, and when one electric motor 304 is damaged, the continuous operation of the fracturing pump can still be ensured by other electric motors 304, thereby reducing the construction risk.
According to an embodiment of the present invention, as shown in fig. 2, the electric drive assembly further includes a second power source 305, the second power source 305 is connected to the electric motor 304, the second power source 305 may be understood as an external power source, for example, a wellsite power grid, a battery, or the like, and when the second engine 301 is not used or the second engine 301 fails, the second power source 305 may fully use the electric drive mode under the condition of satisfying the output power, so as to reduce oil consumption and achieve the effects of energy saving and emission reduction.
