Electrically-driven fracturing pump truck

Abstract

The invention discloses an electrically-driven fracturing pump truck, which comprises a truck chassis with a cab. A lubricating and cooling system, a fracturing pump, a suction manifold, an exhaust manifold, an electrically-driven system and a control system, the suction manifold and the exhaust manifold are connected with the fracturing pump, the electrically-driven system comprises a motor and a motor-driven device, the motor is used for driving the fracturing pump to run, the control system comprises a main power control system and an auxiliary power control system, the main power control system is used for controlling the motor-driven device, the auxiliary power control system is used for controlling the lubricating and cooling system, and the motor-driven device, the main power control system and the auxiliary power control system are powered by an external power source. The electrically-driven fracturing pump truck is simple in structure, reasonable in design, convenient in matching, low in manufacture cost, high in work efficiency and reliability, convenient in energy supply, fine in emission reducing effect, easy in maintenance, capable of overcoming defects and shortcomings of high fuel consumption, difficulty in matching of an engine and a torque converter and the like of a fracturing pump truck in the prior art, and convenient in popularization and use.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, and relates to mechanical operation equipment for petroleum exploitation, in particular to an electrically driven fracturing pump truck. Background technique [0002] Fracturing is an important technical means for increasing reserves and production in oil and gas fields. It is necessary to use high-pressure fluid to first open formation fractures, and then fill the fractures with fracturing sand to enhance formation permeability and oil and gas production. In fracturing construction, the performance of fracturing equipment determines the realization of fracturing technology improvement. Sophisticated fracturing equipment is the necessary technical support for fracturing construction. The total amount of fracturing operations in my country's oil and gas fields is increasing at a rate of 10% to 20% every year. With the development of deep wells and difficult wells, the scale of frac...

Problems solved by technology

The main problems are: 1. When the unit power of the fracturing pump truck reaches more than 1500kW, the cost of the engine rises rapidly and the selection of the model is difficult; 2. Due to the large size and weight of the high-power diesel engine and gearbox, it is not conducive to the design of the vehicle-mounted solution and the development of larger power pump trucks, the diesel engine drive scheme has become a bottleneck restricting the development of new fracturing pump trucks; 3. The matching torque converter and other components have a narrow selection range and high prices; Torque, etc.) all need to be imported, which not only causes high cost of the whole machine, but also hinders the development of equipment with independent intellectual property rights; 4. When the high-power fracturing pump truck formation is running in the field, the fuel consumption is large, and the fuel supply cost is high. Increase the overall operating cost; 5. When the output power of the diesel engine is in the non-economic operating range, the fuel consumption is large, and the adaptability to different operating conditions is poor

6. The high-power diesel engine has high noise and high emission, and poor working conditions for workers
