SUB SURFACE HORIZONTAL GAS RESTRICTOR

摘要

An intake assembly for a well pump restricts gas entry into the pump when the pump is located in a horizontal section of the well bore. The restrictor is located within a tubular intake housing. The intake housing ha s apertures for receiving the flow of well fluid. The apertures are spaced circumferentially around the housing. Once installed in the well, some of th e apertures will be at higher elevations than others. The restrictor partially blocks at least one of the higher elevation apertures and opens at least one of the lower elevation apertures. The gas will be at the higher elevations, thu s it is restricted from flowing in through the higher elevation aperture while th e liquid freely flows into the lower elevation aperture. The restrictor may be of a buoyant material to float upward in the well fluid. The restrictor may also be open in response to contact with the casing wall.
