Mobile electric power generation for hydraulic fracturing of subsurface geological formations

摘要

A fracturing pump transport comprising a first pump configured to pressurize and pump fracturing fluid, a second pump configured to pressurize and pump the fracturing fluid, and a dual shaft electric motor comprising a shaft and configured to receive electric power from a power source and drive in parallel, both the first pump and the second pump with the shaft.

主权项

1. A system for pumping and pressurizing fracturing fluid, the system comprising:
a source of electric power; and a fracturing pump transport coupled to the source of electric power, wherein the fracturing pump transport comprises:
a dual shaft electric prime mover that comprises a shaft that protrudes at opposite sides of the dual shaft electric prime mover;a first pump coupled to a first end of the shaft via a first coupling connection that allows for selective engagement between the first pump and the dual shaft electric prime mover; anda second pump coupled to a second end of the shaft via a second coupling connection that allows for selective engagement between the second pump and the dual shaft electric prime, andwherein the dual shaft electric prime mover is operable to drive the first pump after the second coupling connection disengages the dual shaft electric prime mover from driving the second pump.
