Title:
DOWNHOLE WELL PUMP
Document Type and Number:
WIPO Patent Application WO2003031815
Kind Code:
A3
Abstract:
The pump and pump system (10) of the present invention is designed to remove liquids, gas, sand, and coal fines from gas and/or oil well bores from close to the rock face. The new pump will utilize energy for the "engine" from the surface natural gas compressor or compressors, which forces an adjustable amount of natural gas volume (which equates to pressure or Psig) into an axial turbine (50) or series of turbines to create the correct amount of torque and/or revolutions per minute (RPM) required to create suction at the pump inlet (102) or reverse axial turbine/turbines. This process will allow the pump to remove liquids, sand, coal fines, and gas from the well bore due to a void or vacuum created from the spinning of the reverse axial turbine (50) or turbines.
