Development of a Downhole Turbo-Pump for Geothermal Brine. Phase I:Confirmation of Design Specifications. Phase II:Design and Fabrication of Prototype.

摘要

One obstacle to immediate development of geothermal resources is the lack of a suitable downhole pump capable of handling hot geothermal brines. A concept is proposed wherein downhole motive power is supplied by a hydraulic turbine which is close coupled to a pump suited for brine delivery. Recirculated brine delivered from a surface supply pump provides motive power for the downhole unit.
