Description

Technical Field

[0001] The utility model relates to the technical field of fracturing pump trucks, in particular to a fracturing pump truck. Background Art

[0002] Fracturing is an important technical means to increase reserves and production in oil and gas fields. It requires the use of high-pressure fluid to first open the formation cracks, and then fill the cracks with fracturing sand to enhance the formation permeability and increase oil and gas production. In fracturing construction, the performance of fracturing equipment determines the realization of fracturing technology improvement. Excellent fracturing equipment is an essential technical support for fracturing construction. The total amount of fracturing construction operations in my country's oil and gas fields has increased at a rate of 10% to 20% per year. With the development of deep wells and difficult wells, the scale of fracturing construction has gradually increased. The fracturing equipment owned by China is far from meeting the growing demand for fracturing construction.

[0003] High-power fracturing units are high-tech petroleum equipment. European and American countries, especially the United States, have 80 years of research, development, production and application history in this field. For a long period of time, my country's way to obtain advanced fracturing equipment was to import. Fracturing equipment, especially high-power fracturing equipment, once became a "neck-stuck" equipment in my country's oil and gas production field. Fracturing pump trucks are special operation equipment that install pumping equipment on the chassis of self-propelled trucks to perform high-pressure, large-displacement oil well fracturing and production increase operations. The device consists of two parts: chassis and upper equipment. The chassis mainly provides the transfer function for the whole vehicle, and also provides power for the auxiliary system of the upper part (car platform); the upper part is the working part of the fracturing pump truck, which is mainly composed of a power system, a transmission system, a fracturing pump and a manifold system. The power generated by the power system is transmitted to the power end of the fracturing pump through the transmission system to drive the fracturing pump to work.

[0004] Current fracturing pump trucks directly inject fracturing fluid into oil wells during fracturing operations. However, in extreme cold or cold weather, the viscosity of the fracturing fluid increases, making pumping more difficult and placing a heavy load on the pump. The current method is to install a heating boiler on the ground on site, but the heating boiler needs to be installed on site and cannot be installed with the vehicle. It is troublesome to disassemble and assemble, and the heating speed is slow. Utility Model Content
