Apparatus for pumping subterranean fluids
An apparatus and method for pumping oil or other fluids from the earth is disclosed as using a submersible pump which is suspended in a hole drilled into the earth by means of a flexible cable. Encased in a flexible sheath with the cable are a power cable for the pump and a flexible hose to carry the oil from the pump to the surface of the earth. Control and signal wires may also be encased in the sheath for connection to transducers mounted on the pump. The pump may be easily inserted into or removed from the hole by using a reeling mechanism on the surface of the earth. The pump itself may comprise a submersible motor connected to a rotary to linear motion transducer that causes a pump barrel to reciprocate. The pump barrel moves over a stationary pump plunger, and there are ball check valves in both the barrel and plunger to control the entrance and exit of oil.
