FLOW DEVICE FOR OIL WELLS Filed May 2, 1928 2 Sheets-Sheet 2 B guwm Attarney Patented Dec. 10, 1929 UNITED STATES NATHAN n. RAGLAND, or musxoenn, mint FLOW DEVICE nor, on. win ins Application filed May 2,
The present invention relates to improvements in flow devices for oil wells and has for its principal object to provide a means whereby the lifting fluid which is forced downwardly in the well casing or tubing will be caused to enter the packer head in such a manner as to effect an upward flow of the oil through the hollow packer and upwardly through the eduction pipe that extends from the top of m the hollow packer unit.
A further object is to provide a flow device, wherein a rubber packer is arranged on the outer face of the packer head for engagement with the inner wall of the well casing, to preia vent the air under pressure that is forced downwardly in the well casing around the eduction pipe from entering the lower portion of the casin so as to disturb the oil sand.
A further ob ect is to provide a flow deac vice of the above mentioned character which is simple in construction, inexpensive, strong and durable, and further well adapted to the purpose for which it is designed.
Other objects of the invention will become an apparent as the nature of the invention proceeds and when taken in connection withthe accompanying drawing.
In the accompanying drawings, forming a part of this application and in which like so numerals designate like parts throughout the several views:
Figure 1 is a view partly in elevation and partly in section of the flow device embodying my invention.
Figure 2 is a sectional view, takenuapproximately on the line 2-2 of Figure 1, look ing downwardly and showing the control head in top lan.
Figure 3 is an enlarged sectional view through the lower end of the well casing showing the hollow packer unit and the inclined lifting fluid passages formed in the upper portions thereof, and further showing the manner in which the packer ring engages with the inner wall of the casing, and
Figure 4 is an enlarged sectional view showlng the connection between the control head and the clamp and the adjacent portion of the well casing. In the drawings, wherein for the purpose of ms. Serial No. 94,550.
illustration is shownthe preferred embodiment of my invention, the numeral 1 designates the usual casing that extends downwardly into the well, in the manner well known in the art. The upper end of this casing is externally threaded. A clamp forming member 2 is arranged above the upper end of the well casing and extending vertically through this clamping member is the sleeve 3.
The upper and lower ends of this sleeve so are externally threaded, and'a coupling 4: affords a connection between the upper end of the well casing and the lower end of this sleeve. A control head 5, is removably arranged on the upper threaded end of this sleeve, and a lifting fluid pressure inlet is associated with this control head, in the manner as clearly shown in Figures 1 and2 of the drawings.
Adapted for disposition within the lower portion of the well casing is the hollow packer ead. or unit designated generally by the numeral 7. The lower end of this packer unit is formed with a reduced internally threaded neck 8, in which is secured the upper externally threaded end of the cage 9 for the standing valve 10 and the lower portion of this tubular member 9 has connection with the upper end of the perforated oil inlet pipe 11, in the manner well known in the art.
The upper end of this hollow unit 7 is formed with anenlarged or thickened portion 12 from which extends the reduced neck 13, into which is threaded the lower end of a relatively small eduction pipe 14. This eduction pipe extends upwardly through the well casing, and through the sleeve 3, the upper portion of the eduction pipe projecting through the top of the control head 5 to provide a liquid outlet above the surface of the ground.
. The central portion of the hollow body 7 is formed with an annular channel 15, in
its outer face, and this channel is of relatively great Width and arranged within this channel is the rubber packer band 16, that is adapted for engagement with the inner wall of the well casing 1, in the manner as shown in Fi we 3, for the purpose of preventing the ifting fluid that is forced 1 downwardly in the well casing around the eduction pipe 14, from passing below the unit 7 and disturbing the sand containing the oil.
In operation, air under pressure is admitted to the control head 5, through the inlet 6 and from this control head, the air will pass downwardly in the well casing around the eduction pipe 14. For the purpose of utilizing this air to effect the upward flow of the oil through the hollow packer unit and through the eduction pipe 14, I provide the spaced inclined passages 17.
These passages are formed in the thickened upper portion 1201? the head 7 and the same extend from the outer face of the body to the bore of the neck 13 and by arranging the passages in the manner as shown in Figure 3, it will be readily obvious that the lifting fluid will cause a jet efi'ect and the oil will be raised upwardly through the eduction pipe 14. v i
It will thus be seen from the foregoing description that I have provided a flow device, particularly adapted for use in oil wells, whereby a lifting fluid under pressure may be utilized for admission to the eduction pipe,
to effect the flow of oilupwardly therethrough and due to its simplicity, the device embodying my invention can be readily and easily assembled or disassembled and can furthermore be manufactured or constructed at a very low cost.
While I have shown the preferred embodiment of my invention, it is to be understood that various, changes in the size, shape and arrangement of parts may be resorted to, without departing from the spirit of the invention and the scope of the appended claim.
Having thus described my invention, what I claim as new is:
In a packer .unit for oil wells, a hollow body formed with areduced neck at its lower end to provide an oil inlet, the upper end of the hollow body being formed with a thickened portion, an ed'uction pipe receiving neck extending upwardly from the thickened portion, said body being formed with an annular channel in its outer face, a packing ring fitted in the channel, said thickened portion being formed with'a series of angularly disposed air passages that extend from the outer face of the hollow body to the bore of the eduction pipe connecting neck.
In testimony whereof I afiix my signature.
NATHAN B. RAGLAND.
