MONROE W. CARROLL, F BEAUMONT, TEXAS, ASSIGNOR 0F ONE-HALF TO THOMAS BROWN AND E. L. BROWN, AND ONE-HALF TO H. P. CARROLL, ALL OF BEAUMONT,
TEXAS.
BORING-TOOL.
To all whom it may concern Be it known that I, MONROE W. CARROLL, a citizen of the United States of America, and resident of Beaumont, in the county of J efl'erson and State of Texas, have invented certain new and useful Improvements in Boring-Tools, of which the following is a specification.
This invention relates to drilling and particularly to the drilling of wells, said invention having relation more especially to oil or other deep wells employing casings, the said invention having for its object the provision of novel means for maintaining the drill stem or casing loosely in the hole or bore of the well, permitting its removal for the purpose of interchanging the drill and test screen, means being provided for perfecting a tight joint which will prevent the escape of oil during the testing operation.
A further object of this invention is to provide a drill stem or casing with the testing mechanism associated therewith, the same having novel means for producing a tight joint while at the same time affording certain movement of one element with relation to the other.
With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.
In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification in which the invention is shown by a vertical sectional view.
In these drawings 2 denotes the drill stem or pipe and for convenience of description, this element will be hereinafter referred to as a drill stem and it is to be understood that I mean thereby any casing or pipe which is used in connection with a drill and having the function of a drill stem.
The drill stem is shown as passing through a clamp 3 which is rotated by means of a shaft 4 and gearing 5 so that as the drill stem reciprocates, it is likewise turned to obviate binding of the drill stem. By reason of this provision, the drill stem is free to be drawn from the well or hole at any time for purposes to be hereinafter explained.
Assuming that the drill has been used as associated with the drill stem and the desired depth has been attained and it is de Specification of Letters I'atent.
Application filed May 4, 1916.
Patented (Pet. 31, 1916.
Serial No. 95,410.
sired to test the well, the drill is removed and a screen or perforated bucket 6 is attached to the drill stem by means of the couplings which comprise the extension 7 which is attached to the drill stem by the threaded band 8. The said extension has a r ng 9 which embraces and slides with relation to the cylindrical section 10, the said cylindrical section having at its lower end a ring 11 which forms a shoulder to coact with a flange 12 so that when the members 11 and 12 contact, motion of the member will be communicated to the bucket for lifting it from the well. Packing 18 surrounds the member 10 above the flange 12 so that it practically maintains a tight joint'between the flange 12 and the cylindrical member 10 preventing the escape of oil or water between the bucket and the said cylindrical member. The cylindrical member 10 has a flanged ring 14 on its upper end and the upper edge of the flanged ring constitutes a shoulder 15 which is engaged by a coupling ring 16 on the outer surface of a small pipe 17 which is placed in the drill stem when tests are to be made.
The upper end of the drill stem has a stufling box 18 through which the pipe 17 extends so that a tight joint is effected at this point between the drill stem and the small pipe. Furthermore, the drill stem has an aperture 19 which is incased by a swivel 20 having a branch 21 constituting a coupling for the pipe 22 by which fluid escapes from the space between the drill stem and the pipe 17 The swivel has glands 23 at its ends and packing 24 interposed between the glands and the swivel to me vent leakage at the joints between the swivel and drill stem. The inner tube has a bailing line 25 which supports an ordinary bailer 26 so that the said bailer may be moved in the inner tube.
Assuming that the well has been drilled as heretofore indicated and the drill has been removed and the strainer has been attached or applied to the lower end of the drill stem with the loose joint at the lower end of the drill stem connected to the upper end of the packer which constitutes the extension of the bucket or screen so as to allow muddy water or fluid to return to the top of the earth on the outside of the drill stem without passing down-through the strainer. Immediately after the packer and strainer have' been lowered, to the bottom of the Well or Where the test is desired, the inner or small pipe 17 is lowered into the drill stem until the first flange ring 15 comes in contact With the flange on the upper end of the cylindrical member constituting a part of the 'loose joint. The joints formed will prevent fiuid being pumped into the Well from going down to the strainer and at the same time the bailer will be lowered through the small pipe into the strainer. By reason of the con nections between the cylinder section 10 and the bore of the 'Well, fluid is prevented from passing from the strainer to the drill stem or from the drill stem into the strainer. If, after the test, further drilling is to be done, the drill stem is removed and the strainer is Withdrawn With it so that if the strainer,
and couplings are removed from the stem, the drill may be reapplied to the drill stem and the drill stem reinserted in the Well for further operation.
I claim- 1. In a Well, a drill stem, a pipe in the drill stem spaced from the drill stem, a screen, means for effecting a loose joint beraoaeee l I I l I 'tWeen the drill stem and the said screen,
means for making the loose joints liquid proof to prevent flow of liquid from the drill ed to engage for causing movement of the screen when the cylindrical member is ele vated, a pipe in the drill stem and in the cylindrical member, means for creating a liquid-proof joint between the said pipe and cylindrical member and means for establishing a liquid proof joint between the said cylindrical member and the extension of the screen.
MONROE W. CARROLL.
