Turbine fracturing semitrailer

Abstract

The invention discloses a turbine fracturing semitrailer. The turbine fracturing semitrailer comprises a semitrailer body, a turbine engine, a reduction gearbox, a transmission mechanism and a plungerpump; the turbine engine, the reduction gearbox, the transmission mechanism and the plunger pump are arranged on the semitrailer body, the output end of the turbine engine is connected with the reduction gearbox, and the reduction gearbox is connected with the plunger pump through the transmission mechanism in a transmission mode. The turbine fracturing semitrailer has the beneficial effects thatthrough linear connection of the turbine engine, the reduction gearbox, the transmission mechanism and the plunger pump in the power-transmission direction, excessive transmission loss can be avoided, and efficient transmission performance is guaranteed; and the whole semitrailer is small in size, light in weight, low in the use cost, and low in failure risks.

Description

technical field [0001] The invention relates to the field of oil and gas field operations, in particular to a turbo fracturing semi-trailer. Background technique [0002] In oil and gas field fracturing operation sites around the world, there are two main driving methods for fracturing equipment: [0003] The first driving mode is driven by a diesel engine. The specific solution is that the diesel engine is connected to the gearbox to drive the fracturing plunger pump to work through the transmission shaft. That is to say, the power source is a diesel engine, the transmission device is a gearbox and drive shaft, and the actuator is a fracturing plunger pump. . [0004] This configuration mode has the following disadvantages: [0005] (1) Large size and heavy weight: The diesel engine drives the gearbox to drive the fracturing plunger pump through the drive shaft, which is large in size and weight, limited in transportation, and low in power density. [0006] (2) Not envi...

AI Technical Summary

Problems solved by technology

[0005] (1) Large size and heavy weight: the diesel engine drives the gearbox to drive the fracturing plunger pump through the transmission shaft, which is large in size and weight, limited in transportation, and low in power density

[0006] (2) Not environmentally friendly: Diesel engine-driven fracturing equipment will generate engine exhaust gas pollution and noise pollution during the operation of the well site. The noise exceeds 105dBA, which seriously affects the normal life of the surrounding residents.

[0007] (3) Uneconomical: Diesel engine-driven fracturing equipment has relatively high initial purchase costs, high fuel consumption per unit power during equipment operation, and high daily maintenance costs for engines and gearboxes.

More importantly, during the actual construction process, due to the failure of the gas generator set, the entire electric drive fracturing unit will be paralyzed, which will seriously affect the quality of work and may even lead to work accidents
