Abstract

A modularized, electric pumping unit comprising: a base structure; an electric motor mounted on the base structure; and one or more pump modules. Each of the one or more pump modules includes a pump and a pump module structure, and can further include a pump auxiliary system comprising an oil lubrication pump, an oil reservoir, one or more oil filters, an oil cooler, a sensor package, a speed reducer, or a combination thereof. The one or more pump modules are configured to be removably mounted on the base structure and driven by the electric motor.

First claim

What is claimed is:

1 . A pumping unit comprising:
a base structure; an electric motor mounted on the base structure; and one or more pump modules, each of the one or more pump modules comprising a pump, a pump module structure, and a pump auxiliary system comprising an oil lubrication pump, an oil reservoir, one or more oil filters, an oil cooler, a sensor package, a speed reducer, or a combination thereof, wherein the one or more pump modules are configured to be removably mounted on the base structure and driven by the electric motor.

2 . The pump module of claim 1 , wherein the oil lubrication pump is powered by an electric motor.

3 . The pump module of claim 1 , wherein the oil cooler comprises a heat exchanger, a fan, or a combination thereof.

4 . The pump module of claim 1 , wherein the sensor package comprises one or more sensors for monitoring pressure, temperature, position, or a combination thereof.

5 . The pumping unit of claim 1 further comprising one or more connector panels mounted on the base structure, wherein each of the pump modules comprises cables, hoses, or both that extend to at least one of the one or more connector panels.

6 . The pumping unit of claim 1 , wherein the pump of each of the one or more pump modules is mounted onto the pump module structure of the each of the one or more pump modules via a three-point mounting sub-structure that reduces or prevents translation of flexure of the pump module structure to the pump.

7 . The pumping unit of claim 1 , wherein the speed reducer is positioned on or near the pump and configured to reduce motor input speed to the pump when the pump module is operatively connected with the electric motor and the electric motor is in operation, and a sound blanket on the gear box.

8 . The pumping unit of claim 1 , wherein each of the one or more pump modules further comprises a driveline coupled to the speed reducer, wherein the driveline is positioned above the pump.

9 . The pumping unit of claim 1 , wherein the electric motor comprises a first motor output shaft end and a second motor output shaft end, and wherein the pumping unit comprises two pump modules, a first pump module connected to the first motor output shaft end and a second pump module connected to the second motor output shaft end, whereby the two pump modules are driven by the electric motor.

10 . A pumping unit comprising:
a base structure; an electric motor mounted on the base structure; one or more pump modules, each of the one or more pump modules comprising a pump and a pump module structure, wherein the one or more pump modules are configured to be removably mounted on the base structure and driven by the electric motor; and at least one connector panel affixed to the base structure and comprising connectors for electrical cables, hoses, or both from the one or more pump modules, wherein the electrical cables are configured for supplying electric power to the one or more pump modules, for communicating control signals to the one or more pump modules, for communicating sensor feedback from the one or more pump modules, or combinations thereof and wherein the hoses are configured for supplying fluids to the one or more pump modules, wherein the one or more pump module do not comprise such a connector panel thereon.

11 . The pumping unit of claim 10 , wherein the base structure further comprises one or more mounting points, and wherein each of the one or more pump modules comprises one or more complementary mounting elements, wherein each of the one or more mounting points of the base structure are configured to receive and align with one or more of the one or more complementary mounting elements of the one or more pump modules, to position and align the pump module with the electric motor.

12 . The pumping unit of claim 10 , wherein each of the one or more pump modules further comprises lift components configured for removal of each of the one or more pump modules from the base structure.

13 . The pumping unit of claim 10 , wherein one or more of the one or more pump modules comprise a pump life monitoring system that includes component identification, data processing, data storage, data communications, or a combination thereof.

14 . A method comprising:
operating a pumping unit for pumping a fluid, wherein the pumping unit comprises:
a base structure assembly comprising: a base structure, an electric motor, an electric motor drive, an auxiliary electric power supply, or a combination thereof mounted to the base structure; and
two pump modules, wherein each of the two pump modules is configured for mounting on the base structure and connection to the electric motor, whereby a pump of each of the two pump modules can be driven by the electric motor; and
preventing rotary motion from being transmitted from the electric motor to the pump of at least one of the two pump modules via a decoupler, to provide at least one offline pump module.

15 . The method of claim 14 , wherein operating the pumping unit for pumping the fluid further comprises connecting a fluid inlet on each of the two pump modules to a source of a wellbore servicing fluid, fluidly connecting a fluid outlet on each of the two pump modules to a well, and operating at least one of the two pump modules via the electric motor to pump the wellbore servicing fluid into the well.

16 . The method of claim 14 further comprising replacing and/or transporting the at least one offline pump module, wherein the at least one offline pump module is removed from an assembled configuration of the pumping unit for the replacing and/or transporting.

17 . The method of claim 16 , wherein removing the one or more of the at least one offline pump modules from the assembled configuration of the pumping unit further comprises, for each of the one or more of the at least one offline pump modules:
disconnecting a driveline of the offline pump module from the electric motor; unplugging electrical cables, hoses, or both from connectors on the base structure; releasing complementary mounting elements affixing a pump module structure of the offline pump module to the base structure; and lifting the offline pump module off the base structure.

18 . The method of claim 17 , wherein lifting the offline pump module off the base structure comprises engaging one or more lifting components on the pump module structure of the offline pump module with a lifting apparatus, and utilizing the lifting apparatus to lift the offline pump module off the base structure.

19 . The method of claim 16 , comprising transporting the at least one offline pump module, the base structure, or both, wherein the at least one offline pump module is not mounted on the base structure during the transporting.

20 . The method of claim 19 further comprising assembling a pumping unit comprising the transported at least one offline pump module after the transporting to provide an assembled pumping unit, wherein assembling comprises mounting the at least one transported pump module on the transported base structure of the pumping unit or a base structure of another pumping unit and operatively connecting each of the at least one transported pump modules to an electric motor of the or another pumping unit.
