FRACTURING SYSTEMS AND METHODS FOR A WELLBORE

摘要

The disclosure contained herein describes systems, units, and methods usable to stimulate a formation including a pump usable to pressurize fluid, an electric-powered driver in communication with and actuating the pump, and an electrical power source in communication with and powering the electric-powered driver. The electrical power source can include on-site generators and/or grid power sources, and transformers can be used to alter the voltage received to a voltage suitable for powering the electric-powered driver. Air moving devices associated with the electric-powered driver can be used to provide air proximate to the pump to disperse gasses. In combination with fluid supply and/or proppant addition subsystems, the pump can be used to fracture a formation.

主权项

1. An electrical power system for providing fracturing materials to a formation at a pressure sufficient to stimulate the formation, the power system comprising:
a pump for pressurizing the fracturing material; an electric motor coupled to the pump, together defining a pump/motor combination, the electric motor configured to provide mechanical energy to the pump for the purposes of actuating the pump; and a variable frequency drive coupled to the electric motor and to a power source, wherein the variable frequency drive receives electricity from the power source, and wherein the variable frequency drive provides an electrical signal to the electric motor.
