Semitrailer-mounted turbine fracturing equipment

Abstract

The invention discloses semitrailer-mounted turbine fracturing equipment. Straight-line connection and special chassis design of the whole equipment can double reduce center of gravity of the equipment, stability and safety are better ensured, the structure is simpler, the investment cost and the operation cost are lowered, risks of the whole breakdown of fracturing sites are reduced, transmissionis better, and the semitrailer-mounted turbine fracturing equipment is suitable for continuous operation working conditions with long time and large load. By improving a plunger pump, optimization ofrotating center distances of a crank throw and a crankshaft makes rated power input of the crank throw and the crankshaft increase to 5000-7000 hp, optimization of the transmission ratio of an integrated reduction gearbox on the plunger pump makes the maximum input speed of the integrated reduction gearbox reach 16000 rpm, and ultra-high speed enables reduction gearboxes to be directly connectedwith a turbine engine so as to the solve the problems that turbine fracturing equipment slows down depending on the two reduction gearboxes, and weight of the whole semitrailer is reduced, and boundary dimension of the semitrailer-mounted turbine fracturing equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of turbo fracturing, in particular to a semi-trailer-mounted turbo fracturing equipment. 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.

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 engine and transformer costs.

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
