ABSTRACT:
A fluid-operated turbopump, suitable for installation in the bottom hole tubing of an oil well, is structurally adapted as a hydraulically insertable and removable unit. The turbopump has axially spaced rotary driving and driven impellers operable for overbalancing columns of fluid which are separated by the wall of the tubing, the overbalancing operation facilitating upward movement of fluid from an underground production zone to aboveground storage. A tubular drive shaft interconnecting the impellers is utilized to convey fluid axially through the driven impeller.
