Downhole pump fluid throttling device
In some embodiments, a method for controlling fluid flow through a downhole pump system in a borehole includes moving, via a downhole pump residing below a tubular in the borehole, a first fluid through the tubular, wherein the first fluid includes a compressible fluid. The method may further include increasing an intake pressure of the downhole pump while the first fluid is moving via a control valve system comprising a throttling valve.
1 . A method for controlling fluid flow through a downhole pump system in a borehole comprising:
moving, via a downhole pump residing below a tubular in the borehole, a first fluid through the tubular, wherein the first fluid includes a compressible fluid; and
rotating a rotatable perforated disk of a control valve system from a first position to a second position using a motorized actuator positioned up-hole of the control valve system, wherein actuating the rotatable perforated disk from the first position to the second position increases an intake pressure of the downhole pump while the first fluid is moving uphole,

a flow passage for the compressible fluid in the borehole,
wherein the fixed second disk is longitudinally-adjacently coupled with the rotatable first disk such that at least a first portion of the one or more first perforations overlaps the one or more second perforations, wherein the overlap forms the flow passage.
11 . The system of claim 10 , wherein the motorized actuator is coupled to a gear system including at least one gear coupled with the rotatable first disk to rotate the rotatable first disk.
12 . The system of claim 10 , wherein the overlap influences the intake pressure of the downhole pump.
13 . The system of claim 12 , wherein reducing the overlap increases the intake pressure of the downhole pump.
14 . The system of claim 10 , further comprising a downhole pump controller and one or more sensors, the downhole pump controller configured to:
receive, from the one or more sensors, data measuring attributes of at least one of the downhole pump, the control valve system, the compressed fluid, and the borehole; and
actuate, via the motorized actuator, the rotatable first disk to control a flow rate through the flow passage.
15 . An apparatus comprising:
a control valve system configured to couple with a downhole pump configured for placement in a borehole, wherein the control valve system includes a rotatable first disk having one or more first perforations; and
