Fracturing truck and fracturing equipment set

Abstract

The invention relates to the technical field of fracturing trucks and discloses a fracturing truck and a fracturing equipment set. The fracturing truck comprises a chassis, at least two engines arranged on the chassis, a transmission system which is arranged on the chassis, connected with the at least two engines and used for collecting and transmitting the output power of the engines, and a pressurizing mechanism arranged on the chassis and connected with the transmission system. By means of the at least two engines and the transmission system matched with the engines, the fracturing truck can effectively reduce the manufacturing cost and the model selecting difficulty and effectively improve the operation reliability.

Description

technical field [0001] The invention relates to the technical field of fracturing vehicles, in particular to a fracturing vehicle and a fracturing equipment set. Background technique [0002] As conventional oil and natural gas resources are dwindling, countries around the world have to look for alternative energy sources, such as unconventional oil and gas resources such as shale gas, shale oil, and coalbed methane. A key technology for unconventional oil and gas extraction is fracturing technology. Fracturing technology uses high-pressure pumps to inject liquid with a certain viscosity into the formation at high speed. When the injection rate of the pump is greater than the absorption rate of the formation, the formation will crack or the original tiny gaps will gradually open to form one or more larger gaps. With the continuous injection of liquid, the formed cracks will continue to extend. , so as to improve the seepage conditions of the fluid in the formation, enhance...

Problems solved by technology

Due to the high power required for fracturing operations, in order to meet the requirements, the power of the diesel engine should be large enough to meet the maximum power requirements. However, when the power of the selected diesel engine exceeds a certain power (such as 1500KW), The required cost will rise rapidly, making it difficult to select the engine type, which also results in a narrow selection range and high price for the matching transmission box and other components

[0005] Another reason for the difficulty in selecting the above-mentioned transmission scheme and the high cost is that, worldwide, the technical maturity of components and parts related to fracturing operations and the completeness of the industrial chain vary greatly in various countries. The diesel oil that constitutes the above-mentioned transmission scheme Engines, torque converters or transmission shafts need to be purchased from certain countries or regions, which will result in high costs for fracturing vehicles using this transmission scheme, and are limited by the cycle time and supply of imported parts

[0006] In addition, the existing fracturing vehicles use a single high-power diesel engine as the main power source. The safety and reliability of the above transmission scheme is low, because once any of the diesel engine, hydraulic torque The cracking truck can only stop the fracturing operation for maintenance

Since the fracturing operation sites are generally located in remote areas, and these components are expensive and difficult to prepare in one go, even in countries with relatively mature fracturing operation technology, it will take a long time to resume fracturing operations, which will affect the operation progress
