Description
TURBINE FRACTURING SEMI-TRAILER
TECHNICAL FIELD
The present invention relates to the field of oil and gas field operations, and specifically to a turbine fracturing semi-trailer.
BACKGROUND
In the working sites of fracturing in oil and gas fields all over the world, the driving modes for fracturing equipment mainly include the following two ways:
One driving mode is diesel engine driven, specifically a diesel engine is connected to a transmission through a transmission shaft to drive the fracturing plunger pump to work. In other words, a diesel engine is used as the power source, a transmission and a transmission shaft are used as the transmission devices, and a fracturing plunger pump is used as the actuating element.
This configuration mode has the following disadvantages:
1 5 (1) Large volume and heavy weight: When a diesel engine drives a transmission to drive a fracturing plunger pump through a transmission shaft, a large volume is occupied, a heavy weight is involved, the transportation is restricted, and the power density is low;

In other words, a diesel engine is used as the power source, a transmission and a transmission shaft are used as the transmission devices, and a fracturing plunger pump is used as the actuating element.
This configuration mode has the following disadvantages:
1 5 (1) Large volume and heavy weight: When a diesel engine drives a transmission to drive a fracturing plunger pump through a transmission shaft, a large volume is occupied, a heavy weight is involved, the transportation is restricted, and the power density is low;
(2) Environmental problems: During operations on a well site, the fracturing equipment driven by the diesel engine would generate engine waste gas pollution and noise pollution. The noise exceeding 105 dBA will severely affect the normal life of nearby residents;
(3) Cost inefficiency: The fracturing equipment driven by the diesel engine requires relatively high initial purchase costs and incurs high fuel consumption costs for unit power during operation, and the engine and the transmission also require very high routine maintenance costs.
The other driving mode is electric drive fracturing, specifically an electric motor is connected to a transmission shaft or a coupling to drive the fracturing plunger pump to work. In other words, an electric motor is used as the power source, a transmission shaft or a coupling is used as the transmission device, and a fracturing plunger pump is used as the actuating element.
Although the electric drive fracturing has many advantages itself, the power supply on fracturing well sites is the prerequisite for implementation of the electric drive fracturing.
Date Recue/Date Received 2022-03-21 Generally, it is difficult to supply power for the fracturing well sites in that the power capacity on the well sites is too small to drive the whole fracturing unit, or there are not any power networks at all on the well sites. Therefore, in common electric drive fracturing sites, generators are generally used to generate electricity. The most economical generation fuel is natural gas, but the users employing natural gas need to rent or purchase gas generators. For a fracturing well site without power networks, the power of the gas generator sets need up to at least 30 MW. Purchasing such high-power gas generator sets is a great investment for customers. More importantly, in actual work progress, the accidental shutdown of the gas generator sets would cause the breakdown of the whole electrical fracturing unit, thus seriously affecting the working quality, even causing work accidents possibly.
Therefore, it is an urgent need for a new fracturing equipment to solve the disadvantages of the above exsiting diesel engine-driven fracturing and electric drive fracturing, thus better satisfying the demands on the oil and gas field fracturing market globally.
SUMMARY
To overcome the deficiencies in the prior art, an objective of the present invention is to provide a turbine fracturing semi-trailer, wherein a turbine engine, a reduction gearbox, a transmission mechanism and a plunger pump are connected in a straight line along the transmission direction of power to avoid excessive transmission loss, thus ensuring efficient transmission performance. The turbine engine itself has the advantages of small size, light weight and high power density. For the same outline dimensions and weights, the unit power of the turbine fracturing equipment is more than two times of that of conventional diesel engine fracturing equipment. The turbine engine can use 100% natural gas as the fuel directly, greatly reducing the use-cost compared to the diesel consumption in diesel engine drive and the investment on gas generator sets in electric drive fracturing equipment. Meanwhile, the turbine fracturing equipment are usually operated with the plunger pumps drived one-to-one, unlike in electric drive fracturing equipment, a single high-power gas generator set is used to drive multiple plunger pumps. That is to say, a turbine fracturing equipment is employed to distribute the failure risks of single high-power gas generator onto each turbine fracturing equipment, avoiding that the failure of single gas generating equipment causes the risk of breakdown of the whole set of fracturing equipment.

Compared with the prior art, the beneficial effects of the present invention are as follows: the turbine engine, the reduction gearbox, the transmission mechanism and the plunger pump are connected in a straight line along the transmission direction of power to avoid excessive transmission loss, thus ensuring efficient transmission performance. The turbine engine itself has the advantages of small size, light weight and high power density.
