ABSTRACT:
A downhole gas separator for use with a downhole pump in a producing well bore, the gas separator being secured to the lower end of the pump and generally comprises inner and outer concentrically arranged tubes extending downwardly within the well tubing, the first tube being provided with a plurality of perforations in the sidewalls thereof adjacent the upper portion thereof, and the second tube being provided with a plurality of perforations in the sidewalls thereof adjacent the lower portion thereof. The well fluid contained in the well bore is drawn into the well casing and travels through a long, torturous upward and downward path through the well tubing and gas separator and to the surface of the well bore, with substantially all of the gas being separated from the heavier components of the fluid during the travel. The gas separator is preferably of an overall length at least approximately equal to the length of a single well tubing joint to provide sufficient length of travel for the well fluid to remove substantially all of the entrained gas and to filter substantially all debris from the fluid stream.
