Down-Hole Gas Separator

摘要

A gas separator for separating gas from a fluid in a production stream in a producing hydrocarbon well is described. The gas separator includes a central tube sized to fit into a well casing of the producing hydrocarbon well and having an input at its lower end for receiving the production stream and perforations at its upper end to allow the production stream to flow into the space between the central tube and the well casing. A suction tube is located inside the central tube, the suction tube is operable to draw fluid from the space between the central tube and the well casing and to deliver the fluid to an artificial lift mechanism. A baffle assembly in the gas separator is comprised of a series of baffles, each baffle extending between an inner wall of the central tube and an outer wall of the suction tube for a portion of the available space between the inner wall of the central tube and the outer wall of the suction tube, each baffle offset from the other baffles in the baffle assembly, wherein the baffle assembly is operable to continually redirect the fluid and gas as it travels through the central tube.

1. A gas separator for separating gas from a fluid in a production stream in a producing hydrocarbon well comprising:
a central tube, the central tube being sized to fit into a well casing of the producing hydrocarbon well and having an input at its lower end for receiving the production stream and perforations at its upper end to allow the production stream to flow into the space between the central tube and the well casing; a suction tube inside the central tube, the suction tube operable to draw fluid from the space between the central tube and the well casing and to deliver the fluid to an artificial lift mechanism; a baffle assembly comprising a series of baffles, each baffle extending from an inner wall of the central tube and blocking a portion of the available space between the inner wall of the central tube and the outer wall of the suction tube, each baffle offset from the other baffles in the baffle assembly such that the baffle assembly continually redirects the fluid and gas toward a next baffle in the baffle assembly causing turbulence in the fluid and gas as the fluid and gas travel downward through the central tube toward the suction tube.
