Abstract

A hydraulic fracturing system for fracturing a subterranean formation includes a support structure that includes an electric powered pump, arranged in a first area, the electric powered pump powered by at least one electric motor, also arranged in the first area. The system further includes a variable frequency drive (VFD), arranged in a second area proximate the first area, connected to the at least one electric motor to control the speed of the at least one electric motor. The system includes a transformer, arranged in a third area proximate the second area. The system also includes a slide out platform integrated into the first area, the slide out platform being driven between a retracted position and a deployed position.

First claim

The invention claimed is:

1. A hydraulic fracturing system for fracturing a subterranean formation, comprising:
a support structure having a first area, a second area, a third area, and a fourth area arranged adjacent one another;
an electric powered, multi-plunger pump with up to 15 plungers, arranged in the first area, the electric powered pump coupled to a well associated with the subterranean formation and powered by at least one electric motor, also arranged in the first area, the electric powered pump configured to pump fluid into a wellbore associated with the well at a high pressure so that the fluid passes from the wellbore into the subterranean formation and fractures the subterranean formation;
a variable frequency drive (VFD), arranged in the second area proximate the first area, connected to the at least one electric motor to control the speed of the at least one electric motor;
a transformer, arranged in the third area proximate the second area, the transformer positioned within an enclosure, the transformer distributing power to the electric pump, the power being received from at least one generator at a voltage higher than an operating voltage of the electric pump;
a slide out platform integrated into the first area, the slide out platform being driven between a retracted position and a deployed position, wherein the deployed position provides a work area proximate the electric pump extending outward from the electric pump;
an actuator, coupled to the slide out platform, the actuator driving movement of the platform between the retracted positon and the deployed position, the actuator being a linear actuator forming at least a portion of a drive system, the drive system comprising:
a pair of guide rails, coupled to the slide out platform;
brackets, supporting the guide rails; and
a plurality of wheels engaging the guide rails, the wheels restricting movement of the guide rails in at least two directions, wherein at least one wheel of the plurality of wheels is a vertical wheel and at least one wheel of the plurality of wheels is a horizontal wheel.

2. The system of claim 1 , further comprising:
a filtration trailer fluidly coupled to a turbine coupled to the at least one generator, the filtration trailer receiving an inlet flow of gas, from the well site, and removing one or more components of the gas before directing the gas to the turbine.

3. The system of claim 1 , further comprising:
a pump platform, the pump platform supporting both the electric powered pump and the slide out platform, the slide out platform arranged axially lower than the electric powered pump.

4. The system of claim 1 , wherein movement of the platform is driven by an actuator powered by a DC motor.

5. The system of claim 1 , further comprising:
a controller, electrically coupled to the platform, the controller configured to regulate operation of the platform between the retracted position and the deployed position.

6. A hydraulic fracturing system for fracturing a subterranean formation, comprising:
at least one generator;
at least one switchgear receiving electrical power from the generator;
an electric powered pump, arranged on a support structure, the electric powered pump coupled to a well associated with the subterranean formation and powered by at least one electric motor, the electric powered pump configured to pump fluid into a wellbore associated with the well at a high pressure so that the fluid passes from the wellbore into the subterranean formation and fractures the subterranean formation;
a variable frequency drive (VFD), arranged on the support structure, connected to the at least one electric motor to control the speed of the at least one electric motor;
a transformer, arranged on the support structure, distributing power to the electric powered pump, the power being received from the least one generator at a voltage higher than an operating voltage of the electric powered pump;
an electrically controlled slide out platform, arranged on the support structure, the slide out platform being driven between a retracted position and a deployed position, wherein the deployed position provides a work area proximate the electric powered pump extending outward from the electric powered pump substantially perpendicular to a longitudinal axis of the support structure, the platform being at least partially coupled to a pump platform supporting the electric powered pump;
a filtration trailer fluidly coupled to a turbine coupled to the at least one generator, the filtration trailer receiving an inlet flow of gas, and removing one or more components of the gas before directing the gas to the turbine; and
an actuator, coupled to the slide out platform, the actuator driving movement of the platform between the retracted positon and the deployed position, the actuator being driven by a DC motor, wherein the actuator is a linear actuator forming at least a portion of a drive system, the drive system comprising:
a pair of guide rails, coupled to the platform;
brackets, supporting the guide rails; and
a plurality of wheels engaging the guide rails, the wheels restricting movement of the guide rails in at least two directions, wherein at least one wheel of the plurality of wheels is a vertical wheel and at least one wheel of the plurality of wheels is a horizontal wheel.

7. The system of claim 6 , further comprising:
a controller, electrically coupled to the platform, the controller configured to regulate operation of the platform between the retracted position and the deployed position.

8. The system of claim 6 , the platform comprises:
a handrail; and
a ladder.

9. The system of claim 8 , wherein the ladder is arranged at an angle relative to the platform, the angle being obtuse.

10. An electrically driven slide out platform coupled to a trailer including one or more components for hydraulic fracturing, comprising:
an actuator for driving movement of the platform between a retracted position and a deployed position, the actuator being coupled to a lower area of a standing portion of the platform;
a pair of guide rails, coupled to the platform, the guiderails extending perpendicular to an axis of the trailer and engaging at least a portion of a pump platform;
brackets, supporting the guide rails; and
a plurality of wheels engaging the guide rails, the wheels restricting movement of the guide rails in at least two directions, wherein at least one wheel of the plurality of wheels is a vertical wheel and at least one wheel of the plurality of wheels is a horizontal wheel.
