SHERIDAN P. TSCHAPPAT, OF TULSA, OKLAI-IOIVIA,V ASSIGNOR F ONE-HALF T0 HAROLD CALLAHAN,- OF TULSA, OKLAHOMA.
ROTATABLE TUBING HANGER.
'^' Application filed September 13, 1926. Serial No. 135,190.
My invention relates to a rotatable tubing hanger, used in connection with oil wells.
As is well known, a well drilled with a rotary outfit, is very crooked, in parts. As a result of this, the sucker rods operating in string of tubing, in such a well, continually wear against the side of the tubing, frequently cutting through the same, making it necessary to pull and replace the tubing. Under these conditions, it is frequently necessary to pull the tubing, for replacing the worn tubing sections, as frequently as once a week.
ln accordance with my invention, the tubing is suspended by a member which may be turned, and the pumper may, therefore, turn the tubing slightly, at intervals, such as each morning thereby changing the position of Contact between the sucker rods and the tubing'whereby the life of the tubing is greatly prolonged. In addition to the provision of means to permit of turning of the tubing, the hanger is designed to suspend the/tubing on the casing head, at the top of the well,
v by means of slips which grip around the tubing, as distinguished from the old method of hanging the tubing by en aging the cou pling of the tubing. The evice also provides means to pack off gas and fluid between the casing head and tubing, where there is considerable pressure.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawings, forming a part of this specification, and in which like `numerals are employed to designate like parts throughout the same,
Figure 1 is a side elevation of a tubing hanger embodying my invention, the casing head being shown in sections,
Figure 2 1s a central vertical sectionv through the tubing hanger,
Figure 3 is a plan view of the device, and, .Figure 4 is a horizontal section taken on line 4-4 of Figure 2.
In thedrawmgs, wherein for the purpose of illustration, is shown a preferred embodi-' ment of my invention, the numeral 10 designates a preferably cylindrical outer casing or bowl, having a lower portion` 11 which is tapered and increases in diameter downwardly. The lower end of this outer bowl is adapted to be arranged within the open end ofthe casing head 12, and may Nrest upon a shoulder 13,with packing 14 interposed between the adjacent parts. The outer bowl 10 may be clamped in position by means of bolts 15, engaging the tapered portion 11.
The outer bowl 10 is provided with an annular bottom 16, for the passage ofthe tubing 17. This annular bottom supports an end thrust ball bearing, embodying a lower annular ring 18, resting upon the annular bott-om 16 and an upper annular ring 19, said rings lia-ving grooves 20, for the reception of bearing balls 21, as shown.
Rotatable within the outer bowl 10 is an inner bowl 22, the periphery of which is cylindrical. This inner rotatable bowl 22 i-s provided at `tits bottom with an annular groove 23, for the reception of an upstanding annular rib 24, formed upon the upper annular ribl 19. The inner bowl 22 has its bore 25 tapered, and decreases in diameter downwardly.
Arranged within the innerrotatable bowl 22 are sli-ps 26. I preferably employ three of these slips although any suitable'number may be employed and the slips are preferably of the construction shown in my pending application for tubing hanger, filed February 15, 1926, Serial No. 88,272. However, any well known or preferred type' of slips may be employed. These slips engage the tubing 17 and suspend the same, as is obvious.
The numeral 27 designates a washer, preferably formed of cast iron, which may be arranged upon the tops of the inner bowl 22 and the slips 26. Arranged upon this washer is a packino' ring 28, preferably formed of rubber or other suitable material. This packing ring is engaged by a compression ring 29, which is screw-threaded at 30, for engagement with the inner screw-threaded end 31 of the bowl 10. This compressing ring is provided with an upper extension 32, having projections 33 for convenient engagement with a wrench or the like for turning the same.
In view of the foregoing description, it is apparent that the tubing 17 is directly engaged by thel slips, and supported thereby and accordingly lsuspended at the casing head 12. By screwing down the compression ring ,29, the packing ring 28 may be placed under suit-able compression and a tight joint effected, packing oil as or oil. When it is desired to turn the tu ing, the pumper may 11o suitably loosen the compression ring 29, if necessary, and the tubing may be engaged by a wrench and slightly turned. ln this action, the slips 26 turn with the tubing and the inner bowl 22 turns within the outer bowl l0, by virtue of the ball bearing supporting the same. lit is to be understood that the form oi my invention, herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, eine and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the subjoined claimso Having thus claimz l, A rotatable tubing hanger comprising an outer bowl to be arranged upon the casing bead and adapted for the passage of the tubing, an inner bowl rotatable lwithin the outer bowl, slips within the inner bowl tor described my invent-ion, l
vengaging the tubing, a compressible packing ring arranged within the outer bowl above the inner bowl and slips forming a gastight joint, and a compression ring adapted to be drawn into the outer bowl for engagement with the compressible packing ring.
2. A rotatable tubing hanger comprising an outer bowl to be arranged upon a casing head and adapted for the passage ot the tubing, an inner bowl rotatable within the outer bowl, a ball bearing arranged between the parts of the inner and outer bowls, slips'l within the inner bowl tor engaging the tub-i ing, a oompressible packing ring arranged l Van outer bowl to be arrang head and adapted for the passage of the t tubing, an inner bowl rotatable within ther" within the outer bowl to form a gas-tight joint above the inner bowl, and a compres sion ring adapted to be drawn into the outer bowl for engagement with the packing.
3. A rotatable tubing han er comprising upon a casing neeonioa outer bowl, an end` thrust bearing arranged between the bottoms of the inn-er and outer bowls, slips arranged within the inner bowl for engagement with the tubing, a compressible packing ring Within the top of the outer bowl to form a gas-tight joint. and a compression ring operating within the top of the outer bowl above the packing.
el, A rotatable tubing hanger comprising an outer bowl to be arranged upon the casing head and adapted for the passage of the tubing. said bowl being provided at its bottom with a lateral shoulder, an inner bowl rotatable within the outer bowl and having a tapered bore and terminating at its top at an elevation beneath the top ot the outer bowl, an end-thrust bearing arranged between thebottom of the inner bowl and the shoulder of the outer bowl, slips arranged yring and having screw-threaded engagement within the outer bowl.
5. A rotatable tubing hanger comprising an outer bowl to be arranged upon the cas ing head and adapted'tor the passage o: the tubin an innerbowl mounted within the outer y owl to turn with relation thereto and having a tapered bore, the top of the inner bowl terminating at an elevation below the top ot the outer bowl, slips within the tapered bore of the inner bowl, a compressible packing ring arranged within the outer bowl above the slips for forming a gas-tight joint, and a compression rin above the compressible packing ring an adapted to be moed downwardly into engagement therewit -In testimony whereof li amx my signature.
