yBY MFL Patented Mu- 28, 1933 UNITED STATES PATENT OFFICE y RUSSELL GIESEY, OF OKLAHOMA CITYLOKLAHOMA, ASSIGNOB TO REED ROLLER BIT COMPANY, F HOUSTON, TEXAS, A CQBIORATON v0I? TEXAS DEEP WELL nana.v
This invention relates to deep well drills. T he drill stem employed in deep well drilling comprises a pipe made in sections and having on its lower end a drill bit. A long drill stem is very heavy and for reasons well known to those skilled in the art it must be removed from and then again lowered into the well at certain intervals as the drilling proceeds To reduce the strain on the hoisting apparatus when the drill pipe is lowered into the well a'valve, known as a float valve, is mounted in the drill stem to prevent the passage of water in the well upwardly therethrough, whereby a portion of the Weight of the drill stem is placed upon the water in the well. This invention has for one of its objects .the provision of a new and improved fioat valve of this type.
Conventional vdeep well core drills comprise a drill stem having a bit secured to the lower end thereof and having a central opening, and a core barrel within the stem to receive and retain the core of the formation entering through. said opening. In the upper end of the core barrel is a relief valve serving to permit the escape from the barrel of fluid that would otherwise be confined therein and to prevent the passage from the -interior of the drill stem into the barrel of.
ing slush downwardly through the drill stem and core barrel, but this cannot be done with the conventional core drill because the relief valve will not permit the slush to enterthe core barrel. This invention has for another of its objects the provision of a core drill embodying new and improved means -whereby the relief valve will be held away from its seat so that slush may be pumped-downwardly through the drill stem and core barrel to wash out the latter, and then released, to perform its usual function during drilling operations.
A furtherA object is to. provide in 'a'core M dlillh a new and improved combination of 'partsfincluding a float valve and a relief valve. i
` Other objects will hereinafterap'pear.-
The preferred embodiment of the invention is illustrated by the-accompanying drawing wherein Fig. 1 is a partly vsectional ele-` vation'of the drill; Fig. 2,1m enlarged fragmentary sectional view, showing thel posi- V tions of the parts when, slush is being pumped through the-core barrel; and Fig. 3,
a view`similar to Fig. 2-and illustrating-the positions of the parts during drilling. y 60 f In the drawing the drill stem is indicated at 1. It has secured on its lower end a bit 2 having a central .opening 3. Within the drill stem 1 is a core barrell 4 to receive and retain a core of the formation entering throughthe opening'. Any conventional core catcher may, if desired, be placed in the opening 3 or in the lower vendA of this core barrel 4. In the upper end of the core barrel is a flared opening 5, ada ted to receive 70 the relief valve 6. The core barrel 4'is substantially concentric with and spaced from the drill stem 1 so that slush pumped downwardly in the drill stem may pass through the space between the core barrel 4 and drill 75 stem 1 and finally out of the slush passage- -ways 7 in the bit.
Above the core barrel is a val-ve guide 8 in which the stem 9 of the float valve 10 is vertically reciprocable. When the valve i.
10 is upon its seat 11, fiuid cannot pass up-` wardly in the drill stein. Surrounding the stem 9 and bearing upon the guide Sand-the cap 12 carried by the valve stem is a spring 13 which serves 'to' yieldably hold the valve 10 closed.
The relief valve 6 is releasably held in the float valve 10 by the radially expansble ring 14. Within. the valvestem 9 is a relief valve releasing in 515 normally held in its inactive position by the'spring 1 6 which bears downwardlyagainst' the end wall of the stem 9 and upwardly against the abutment V17 fixed on the pin 15.
The pin actuator isindicated'at 1'8 in Fig. 95
.y AWlienawdri11slower-@duim the warme 10d` l the drill stem so that there will be no fluid in the pipe in the drill stem 1 above the float valve 10. A. portion of the weight of the drill stem is thereby placed upon the fluid in the well.
After the drill stem has been lowered to the bottom of the well, or to any predetermined point, slush may be pumped downwardly in the drill stem. Overcoming the resistance of the spring 13 and the pressure of the fluid below the float valve 10, the slush will open the valve 10 and pass downwardly through the opening 5 and into the core barrel 4. After the core barrel has been washed out by the slush passing therethrough, the driller may then drop into the drill stem the pin actuator 18. The actuator 18, moving downwardly in the drill stem, will strike the pin 15 and move it downwardly against the resistance ofspring 16 to force the relief valve 6 out of the float valve 10l against the resistance of ring 14. The relief valve 6 will thereupon fall into the opening-5 to close it. The drill stem may then be rotated to penetrate the formation. The relief valve 6 will then perform its usual function; that is, it will serve to prevent the entrance of slush into the core barrel 4 through the opening 5 and will permit the escape from the core barrel of fluid that would otherwise be confined therein.
The invention is not limited to the preferred embodiment herein disclosed. Various changes may be made within the scope of the following claims.
