TECHNICAL FIELD

The present invention relates to the technical field of power generation, and specifically to a system for providing mobile power.

BACKGROUND

The oil and gas industry generally adopts hydraulic fracturing to promote the production of hydrocarbon wells (for example, oil or gas wells). Conventional fracturing equipment generally has the problems of occupying a large area, causing severe environmental pollution and so on, failing to satisfy the increasingly serious environmental requirements and the requirements on the area occupied by well-site operations.

A complete set of electric drive fracturing equipment will effectively reduce the discharge of environmental pollutants, the occupied area, noise and the operation and maintenance costs. With the use of a complete set of electric drive fracturing equipment and the continuous increase of the power of the electric drive fracturing equipment, higher requirements are imposed on power supply at the operation site. At the well-site, the power supply for fracturing equipment generally cannot be realized by using a power grid. Moreover, the fracturing operation has the characteristic of short operation cycle, and fracturing equipment needs to be moved among different well-sites. Generally, because various parts of a power supply system require different assembly, transportation and installation processes, the installation time of the power supply system will be up to half to one month.

Therefore, how to provide a mobile power supply system which can be installed quickly and conveniently at the electric drive fracturing operation site is currently a great challenge for electric drive fracturing operations.

SUMMARY

To overcome the deficiencies in the prior art, an objective of the present invention is to provide a system for providing mobile power, in which the required equipment for the power supply system at fracturing fields as well as connection cables and connection hoses are integrated properly, assigned onto three transport vehicles for movement and effectively connected, realizing the quick movement and quick installation of the power supply system at the fracturing fields.

The objective of the present invention is achieved by the following technical measures: A system for providing mobile power, including a turbine generation transportation unit, an exhaust transportation unit and an auxiliary system transportation unit; the auxiliary system transportation unit and the exhaust transportation unit are connected to at least one side of the turbine generation transportation unit; the turbine generation transportation unit includes intake components, a gas turbine, a generator and a first transport vehicle, and the intake components, the gas turbine and the generator are connected in sequence and disposed on the first transport vehicle; the exhaust transportation unit includes a mobile accessory, an exhaust stack, an exhaust silencer, an exhaust joint and a second transport vehicle, and the mobile accessory, the exhaust stack, the exhaust silencer and the exhaust joint are disposed on the second transport vehicle.

Further, the turbine generation transportation unit further includes an electric power unit and a control system, the electric power unit is configured to output electric power from the generator, and the control system includes a gas turbine control unit and a generator control unit.

Further, the intake components are disposed at a forward travel direction end of the first transport vehicle and connected to the gas turbine through intake joints.

Further, the intake components include an intake silencer and an intake filter.

Further, the auxiliary system transportation unit includes a gas supply skid, a water washing system, a fire fighting system, a lubrication system, a ventilation system, other auxiliary system and a third transport vehicle; the gas supply skid, the water washing system, the fire fighting system, the lubrication system, the ventilation system and the other auxiliary system are disposed on the third transport vehicle.

Further, the exhaust stack is hinged with the exhaust silencer; during transportation, the exhaust stack and the exhaust silencer are arranged side by side, while in working state, the exhaust stack is disposed on the top of the exhaust silencer.

Further, the exhaust stack can rotate 180° around the hinge point.

Further, different shapes of exhaust joints can be arranged according to the customer's site environment.

Further, the shape of the exhaust joint is a vertical cylinder or an elbow.

Compared with the prior art, the present invention has the following beneficial effects:

1. Intake components and a turbine generation system are combined on one transport vehicle and installed together, then transported to customer sites directly, thus saving the installation time at the user sites.

2. The intake components are disposed at a forward travel direction end of the first transport vehicle, and connected horizontally to the turbine generation system, properly integrating the spatial arrangement of all equipment on the first transport vehicle and facilitating the transportation.

3. The connection between the exhaust stack and the exhaust silencer of two different location relationships at transportation and working states not only meets the requirements of road transportation, but also meets the requirements of exhaust gas emission during operations.

4. The exhaust transportation unit is further provided with a mobile accessory (mainly including hoses, cables and the like used for connecting the auxiliary system transportation unit and the turbine generation transportation unit at working sites), so that the connection hoses and cables at power supply sites can be effectively arranged and collected together to reduce the workload required for connecting the cables and hoses at sites.

5. The exhaust joint can be arranged as a vertical cylinder or elbow type, so that the exhaust transportation unit can be connected to the turbine generation transportation unit in a T-shape or side by side, so as to better meet the site environment of different customers.

The present invention will be described in detail below with reference to the accompanying drawings and specific implementations.
