Cyclonic strainer

摘要

A cyclonic strainer for a well intake that provides for improved separation of gas and fluid in naturally flowing wells during mechanical pumping operations. The strainer includes an elongated member having a channel formed longitudinally therein. A plurality of apertures extend through the elongated member angled downwardly into the channel and away from a center of the channel allowing for a better shear between gas and fluids. The angle of the ports causes fluid to be forced in an opposite direction, resulting in gases and fluids shearing more quickly and cleanly, due to kinetic energy. The angle of the ports can be varied to accommodate different conditions in various well environments. In well environments in which gaseous conditions are extreme, it can be desired for the ports to be sloped southwardly or downwardly at a greater angle than for well environments in which gaseous conditions are not as extreme.

1. A cyclonic strainer comprising:
an elongated member having a northern end and a southern end, only one channel running longitudinally down a central area of the elongated member; a plurality of apertures extending through said elongated member into said channel in said central area of said elongated member, wherein the plurality of apertures are angled downwardly at an angle between zero and sixty degrees toward the southern end and away from a center of said channel; and a hollow tail pipe extending from the southern end, wherein the tail pipe has a smaller diameter than the elongated member; wherein the plurality of apertures are angled to allow gas to be sheared away from fluids to prevent gas from entering the channel through the apertures and to cause gas to travel northward while bypassing the apertures, wherein the plurality of apertures are offset and extend asymmetrically from said center of said channel in order to impart a cyclonic rotation on said fluids as they pass through said apertures and travel northward within said center channel, wherein said apertures are adapted to cause said fluids to flow through said apertures in both a downward direction and an asymmetrical direction from said center of said channel causing the gas to be sheared away from the fluids; wherein fluid also flows into said channel of said cyclonic strainer through said tail pipe in an upward vertical direction; wherein said fluid that flows into said channel of said cyclonic strainer through said tail pipe joins with fluid that flows into said channel of said cyclonic strainer through said apertures so that all of said fluid within said channel is centrifuged against an interior wall of said channel; and wherein gas from said fluid that flows through said tail pipe is directed toward said center of said channel and travels northward through said center of said channel.
