Mobile, modular, electrically powered system for use in fracturing underground formations

摘要

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems.

主权项

1. A system for hydraulically fracturing an underground hydrocarbon bearing formation at a wellbore that pumps fluid from the wellbore into the formation, the system comprising:
a plurality of pumps powered by one or more electric motors and fluidly connected to the wellbore, the pumps configured to pump fluid into the wellbore at a pressure sufficient so that the fluid passes from the wellbore into the formation, and fractures the formation, wherein a fracturing module comprises at least one of the pumps; at least one variable frequency drive connected to the one or more electric motors to control the speed of the motors, the at least one variable frequency drive capable of performing monitoring and controlling of the one or more electric motors; and one or more generators electrically connected to the plurality of pumps to provide electrical power to the pumps, wherein the fracturing module is mounted on a trailer connected to a manifold system, and wherein the trailer is configured to isolate the fracturing module from the trailer such that the fracturing module is adapted to be removed from the trailer without disconnecting the trailer from the manifold system for fracturing operations.
