Abstract
A down-hole jet pumping apparatus and method for removing accumulated water in a small diameter well bore are described. Chosen fluids are pumped under high pressure from a surface pump through a 3-way valve into a tube disposed in a well bore. The jet pumping apparatus includes a down-hole accumulator connected to an eductor. The high-pressure fluid is stored in the accumulator and may be released to the surface reservoir by the control valve through the tube along with the fluid to be pumped drawn into the eductor. When the accumulator is exhausted, the control valve again directs high-pressure fluid from the surface pump to the accumulator until a chosen pressure is achieved in the accumulator. The fluid pressure in the accumulator is maintained using a gas-charged metal bellows. Hydraulically driven jet boosters are described for increasing the fluid pressure along the tube in deep wells.
