WELL-PUMPING APPARATUS.
Application filed February 7, 1927. Serial No. 166,284.
- This invention relates to well pumping apparatus'and more particularly to an im proved form of tubing. bleeder.
During the pumping of a well, the well tubing is generally either partially or wholly filled with the liquid being pumped, and the liquid is means of a standing valve or the like, which is disposed at or near the bottom of the pumping "apparatus. When the pumping of thewell has been completed, and it is desired to withdraw the tubing, it is ordinarily necessary to pull the tubing while it is still filled with liquid. This not only imposes a considerable strain on the lifting apparatus but messes up the derrick floor.
My invention contemplates as one of its objects the provision of means for draining a well tubing in order to lighten the loa which must be lifted in raising the tubing. In a' more specific aspect one of the objects of the invention is to provide a tubing bleed- I er or valve which normally operates to prevent any backward flow of liquid but which can be readily opened to permit quick draining of the tubing.
Other objects, features and advantages of the invention will readily appear as the description thereof proceeds.
In the drawing:
Figure 1 is'a longitudinal sectional view through a tubing bleeder embodying my invention, showing the Figure 2 is a view of the same tubing bleeder partially in section and drawn to an enlarged scale,'showing the bleeder in open position.
Referring to the drawing, there is shown a portion of the lower end of the well casing 10 which at its upper end is connected in the usual manner to the well pumping apparatus. A tubular member 11 which is internally tapered throughout its length is secured to the .lower end of the tubing 10 by means of a coupling member 12. An m verted L shaped slot 13 having at its upper 13 is formed in extremity an ofiset portion the wall of the tubular member 11. A second tubular member 14 which' 'is externally tapered. to correspond to the internal taper of the member 11 is positioned partially within the member 11 and adapted to telescope therein. A stud 15 is secured in the wall of the tubular member 14 with its extending retained within the tubing by bleeder in closed pos1-' head projecting into the slot 13 so as to restrict the relative movement of the telescoping members.
vA standing valve 16 is positionedwithin the bore of the tubular member 14. The lower end of the tubular member 14. which. extends beyond the lower end of the mem ber 11 is secured to a short section of tubing, such as a shoe, or as illustrated-a perforated section of pipe 17 constituting a strainer, by means of a coupling member 18. Dur1ng normal pumping operations a slight tension is maintained upon the tubing and particularly on the cooperating faces of the members 11 and 14 due to the weight of the standing valve 16 and the strainer 17, this tension being suflicient to insure a snug fit between the tapered sections 11 and 14: so
as to prevent any downward leakage of liquid between these members.
Whenit is desired to drain the tubing prior to withdrawing it from the well the whole apparatus is lowered until the pipe section 17 rests upon the bottom of the well. The inner tubular member 14 then; telescopes within the member 11, leaving a space such tained as the tubing is withdrawn from the well the casing 10 which is rigidly secured to the member 11 by the coupling 12 is rotated slightly to the right and on account of the shape of the slot 13 this slight rotary motion of the member 11 relative to the member 14 moves the stud 15 into the offset portion 13 of the slot, thereby locking the telescoping members in position with a fixed space between their adjacent walls. Thus as the tubing is raised to the surface by the usual lifting apparatus the entire liquid content of the tubing is drained out and flows back into the well.
Q Apparatus of preferred form and con-" struction has been illustrated and described for the purpose of showing one way in which the invention may be practiced, but the in- 'ventive thought upon which the invention is 'as 19 through which the liquid in the tubing space between them through which liquid in the well tubin can escape.
2. A well tu ing bleeder comprising a pair of tapered tubularmembers concentrically jdisposed throughout a portion of their lengths, a standing valve disposed within.
the inner of the tubular members, means for normally maintaining the tubular. members close engagement to prevent leakage be- "tween their adjacent walls, means .-for telescoping the tubular members to-"provide a space between them through which liquid in the welltubing can escape, and means for maintaining the tubular members in spaced relation.
. 3. A well tubing'bleeder comprising a pair of tapered tubular members concentrically disposed throughout a portion of their length, a standing valve disposed within the inner of the tubular members, a perforated pipe secured to the lower extended end of the inner tubular member to maintain the adjacent walls of the members in sealing engagement, and means for telescoping the tapered members to provide a drama 6 space therebetween through which the liquid in the well tubing can fiow back into the Well.
d. A well tubing bleeder comprising apai of tapered tubular members concentrically disposed throughout a portion of their lengths, the outer of said tubular members being formed with an elongated slot having an offset portion at its upper end, a stud secured to the Wall of the inner tubular memher with its projecting portion adapted .to slide in the slot of the outer member, a standing valve disposed in the bore of the inner tubular member to revent any backflow of liquid therethrougi to the well, and means for telescoping the tubular members to provide a space between their adjacent walls through which liquid confined in the Well tubing by the standing valve can flow back to the well.
In witness whereof I have hereunto set my hand this second day-of December 1926.
