MITIGATING WATER INCLUSION IN DOWNHOLE PUMPS

摘要

Downhole pumps may include, at the inlet, a component that reduces the amount of water taken up by the pump. For example, a downhole assembly may include a tool string that includes a fluid pump, a fluid intake subassembly, a motor, and a downhole control system each coupled such that a fluid flowing into the fluid intake assembly is conveyed to the fluid pump; one or more inlets defined in the fluid intake subassembly; a flow line fluidly coupled to at least one of the one or more inlets and containing a filter component that contains a filter media at least partially coated with a relative permeability modifier (RPM), wherein the fluid flowing through the flow line contacts the RPM.
