OIL-WELL DEVICE. J

Patented Dec. 5, 1905.

Application med my S, 1905. serai No. 268.220.

- Vania, have invented certain new and useful Improvements in Oil-Well Devices, of which the following is aspecification, reference behad therein to the accompanying drawings. ,l This invention relates to certain new and useful improvements in working barrels for oil-wells; and the invention has for its object the provision of novel means in connection with a working barrel for agitating the sand formation of an oil-well to increase the flow of the well and its general production.

In connection with the agitating `means of my improved working barrel I employ'novel means for regulating the agitation andfor producing an agitation at any desired pointV within the sandforrnation of the well. v

With the above and other objects in view the inventionv finally consists in the novel construction, combination, and arrangement of parts, which will be hereinafter more fully described and then specifically pointed out in the claims, and referring to the drawings tional view of one of the plugs used inconaccompanying this application like numerals of reference designate corresponding parts throughout the severalviews, in which- Figure 1 is a vertical sectional view of a working barrel constructed in accordance with my. invention, illustrating the same positioned Fig. 3 is a cross-sectional view taken on the l line w w of Fig. 1. Fig. 4 is a vertical secnection with the working barrel. Fig. 5 isa transverse sectional view taken on the line of Fig. 4. Fig. 6 is a vertical sectional view ofa sleeve or sprayer used in connection with the working barrel. Fig. 7 is a transverse sectional view taken on the line m 'of Fig. 6. Fig. 8 is a detail perspective view of a conventional form of plug used in connection with the working barrel. Fig. 9 is a vertical sectional'view of a detachable sleeve. Fig. 10 is a sectional view of a collar. Fig. 11 is a similar view of aV sleeve. Fig. 12 is a detail view of a collar. l

In the accompanying drawings, Ihave illus- 7 of the drawings.

tratedthe lower end of a pipe 1, which is adapted to extend into the sand formation 2 of an oil-well, and upon thev end of this pipe it has been the practice to'secure the ordinary type of working barrel, which is generally used in oil-well pumping. I dispense with the ordinary type of workingbarrel and employ a specially-constructed barrel adapted to agitate the sand'formation 2. In order to support my improved barrel, I provide the nlower end of the pipe l with a sleeve 3, having a central depending pipe 4, the upper end `of which terminates in an `open1ng 5, formed in the sleeve 3. The lower end of the pipe 4 is provided with a plurality of circumferentiallyarranged openings 6. ,The sleeve .3 is provided with a depending interiorly-screw-threaded flange 7 and in this iange is secured the .screw-threaded end 8 of my improved working barrel. The working barrel consists of an inner annular shell 9'and an Integral outer `shell 10, these shells providing an annular compartment 1l Within the working barrel. The shells are braced by vertically-disposed ribs 11a, and the annular compartment 11 is centrally partitioned by a horizontal wall 11b.

some of the openings 12L of the sleeve 12.'

To retain the sleeve 12 within the lower end of the barrel, I employ a collar 15, (see Fig. 12,) this. collar being secured upon the screwthreaded end 16 of the barrel.

Both ends of the shell 10 are provided with openings 16 and 17, and in the opening 17 is mounted a screw-threaded plug 18, whilein the opening 16a is secured an upwardly-extending. tubeA 19, which `carries a sleeve 20. -This sleeve is clearly illustrated in Figs. 6 and The one end of the sleeve IOO is screw-threaded, as indicated lat 21, kto support another section of tubing 22 .in case it is desired to use the same. In the sleeve 2O upon with a radiallydisposed aperture 24, which establishes communication between the tubing 19 and the exterior of the sleeve.

The outer shell 10 is provided with a plurality of staggeredly-arranged screw-th readed apertures 25, and in each one of these aper- 'turesI secure a plug 26, which is clearly illustrated in Figs. 4 and 5 of the drawings. Each plug is provided with an annular groove 27, forming a collar 28, which is provided with a plurality of vertically-disposed apertures 29. rIhe plug is provided with an opening 30, communicating with the annular groove 27 by a port 31. These plugs are screw-threaded, as indicated at 32, whereby they may be secured in the screw-threaded openings 25 of the outer shell 10.

In operation the oil passing through the working barrel is adapted to pass through the openings 6 of the pipe-4, openings 14a of the inner shell 9 into the annular compartment 11 of the working barrel, from where it passes through the plugs 26, mounted in the openings of the outer shell 10. This oil is adapted to spray and contact with the sand formation of the oil-well and agitate the same, whereby a larger flow of the well will be produced. At times it may be necessary to agitate portions of the same formation which cannot be conveniently reached by the working barrel, and for this reason I have devised the tubing 19 and the sleeve 20, which is adapted to carry the oil upwardly and distribute it against the sand formation above the working barrel.

The plugs 26 which I employ are specially constructed to prevent the plug from rusting or corroding, and in some instances I may find it advisable to dispense with the small openings 29 of the plugs and continue the openings 30 right through the plug-body. In some oil-well sand formation greater agitation is required in connection with some than with others, and should it be desired to decrease the agitation a number of plugs 26 can be removed and the ordinary type of plug 37 secured in the openings 25, consequently reducing the amount of oil ejected through the outer shell 10.

In connection with the working barrel I may employ a gravity-valve 36, which is preferably mounted in the sleeve 15, this valve being employed 'to prevent the oil passing downwardly into the Well, but permitting of the same passing upwardly. It will be observed that l have provided the upper end of the Working barrel with the depending pipe 4, which is substantially the same as the detachable sleeve 12, with the exception that the sleeve 12 can be readily removed and a sleeve 38 placed therein to close the openings 14a of the working barrel in case it is not desired to use the same. In some instances it may be desirable to use a detachable sleeve in lieu of the pipe 4, in which case a collar 39 (see Fig. 10) is used in lieu of the collar 3.

It will be observed by the construction of my improved working barrel that either the pipe 4 and the sleeve 12 may be used at one time or either end of the working barrel used independently of the other end, and I do not care to confine myself to the manner in which it is used, as the working barrel can be readily reversed, the plug 13 being removed and replaced by the pipe 19, while the opening 16 is closed by the plug 18, it always being essential that the valve 36 be used at the bottom of the working barrel.

I have provided the openings 6 at the lower end of the pipe 4 in order to cleanse the oil passing into the annular compartment l1 of all sediment or foreign ingredients detrimental to the sand formation 2, the perforated plate 23 of the sleeve 2O being employed for the same purpose.

It is thought from the foregoing that the construction, operation, and advantages of the herein-described working barrel will be apparent without further description, and various changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit of the invention or sacrificing any of the advantages thereof.
