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...

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...
