Application IedIOctober 6, 1926. Serial No. 139,933.
This invention relates` torotary drill stems for drilling deep wells. Y
In 'this method of drilling, circulating water is passed down the drill lstem and supplied to the drill bit at the lower end of the drill stem; It frequently happens that a drill bit will be kept in use although it is badly worn and requires to be redressed and resharpened; and drillers have a tendency. to force the cutting of a dull bit by increasing the weight on the bit. On account of using dull or worn bits, and forcing. them in this way, they frequently become stuck in the hole and occasion thetwisting off of the drill stem, with incidental Aloss of time and money in raising the drill stem and repairing the break. v
The general object of this invention is to provide a Adrill stem having a constructlon such that the weight upon the drill stem is limited but is sufficient to enable the drill bit to cut properly if it is in good cutting condition; also the provide a'construction which will prevent the weight upon the drill bit from being increased beyond this predetermined limit without automatically shutting oit the circulating water which isv essential to the drilling operation. ln other words, l provide a construction for this apparat-us which will automatically shut ofi' the flow of circulating water if too much weight is placed upon the drill stem. y
Further objects of the invention will appear hereinafter.
The invention consists of the novel parts and combination of parts to be described herean eiiicient circulation shutoff device.
A preferred embodiment of the invention is described in the following specification,v
while the broad scope ofthe invention is pointed out in the appended claims.
ln the drawing: Figure 1 is a vertical section supposed to be taken at the bottom of a well and showing a portion ofthe casing in section and the drill stem .embodying my improvement i'n side elevation, certain parts being brokenvaway.
Figure 2 is a vertical section taken on the line 2 2 of Figure l upon an enlarged scale and particularly illustrating my improvement. Y
Figure 3 is a cross-section taken on the line 3 3 of Figure 2 upon an enlarged scale. Figure 4 is a section taken through the lower part of my circulation shuton'a and' showing the parts in the relation which they have when the dev-ice is operating to shut off the flow of the circulating water.
Figure 5vis a cross-section through one of my shutoff devices ata point corresponding to the line 3 3 but showing a modified embodiment of the construction for enabling the upper section of the-drill stem to impart movement to the lower section.
Referring to the parts, l represents a casing at the lower end of which a drill bit 2 is operating, the same being attached to the lower; section 3'of a drill stem. My shutoff device 4 is attached to the upper end of this lower section 3 and connects it tothe lower Aend of the upper section 5 of the drill stem.
My shutoff device comprises an'upper member which is connected to the upper section of the drill stem and a lower member connected to the lower section of the drill stem. These members are connected together Kfor sliding movem nt and have means to enable the upper member to rotate the lower member to impart rotary movement to the drill at the lower end of the drill stem; these members vhave water circulation ducts for conducting the circulating water down the drill stem and one of the members has a port through'which this water flows. The other of said members is provided with means for closing this port to shut off the flow of the circulating water if the upper member of the upper section of the drill stem is supported on the lower. member. 'In order to accomplish this, I'provide the lower end of the upper section 5 of the drill stem with a reducing coupling 6, to the lower end -of which a sub- 'eoupling 7 is attached. To the lower end ofthis sub-coupling 7' a tubular plunger S is attached, having a bore 9 through it which communicates with the Aducts or bores of the couplings 6 and 7 so as to conduct circulating water down the drill stem. This plunger 8 slides freely through' the upper end of a barrel l0 and within the barrel the plunger has a piston head 11 which is provided with packing rings l2 for a purpose which will appear hereinafter. At the upper end of the barrel is a long integral head 13 and the lower end of the barrel is closed by a head 14 which is in the form of a coupling screwed into the lower end of the barrel, the said coupling having a bore or port 15 through it with an enlarged counterbore or mouth 16 at its upper end. This counterbore terminates in a conical seat 17. rihe lower end of llO the head or coupling 14connects to the lower section 3 of the drill stem. The plunger 8 and the head 13 have a correlated an 'ular' construction to enable the rotation o the `plunger 8 to be imparted` to the barrel 10.
For example, the plunger 8 'may be of the general form illustrated in Figure 3 having two diametrically opposite cylindrical faces 18 and flat side faces 19 which t against corresponding faces in the head 13. How-V head 14, the flow o-fcirculating water will bel shut oit. In order to accomplish this, I provide the lower end of the piston head with a downwardly projecting plug or nose 24, the lower endvot which is tapered so as to present a conical face 25. This plug is provided with a cross-port 26 which communicates with the bore 9 of the plunger and emerges at both sides of the cylindrical face of the plug 24. The plug 24 is of suilicient diameter to iit neatly in the cylindrical counterbore 16 of the head 14, and the conical face 25 is constructed to lit upon the seat 17.- With this relation of the parts, it will be evident that when the drill stem is in operation and the piston head 11 is held elevated above the head14, the circulating water will pass down through the bore 9 into the chamber in the lower end of the barrel, and thence down-v,
wardly through the port 15 in the direction of thedrill bit 2.
At this time, the weight upon the drill bit will be the weight ofthe lower section 3 of the drill stem. This weight can be any amount desired and can be regulated by changing the length of the lower section of the drill stem. However, ifl the driller should attempt to increase by letting the upper section of` the drill stem down'onto the lower section, the plug'27 will 'extend down into the counter-bore 16, thereby shutting otf the flow of the circulating water and rendering it impossible to continue the operation of the-drill. Of course, as soon as the driller inds that the circulating water has been shut 0H', he will realize that the drill Stein should be drawn and a sharpened bit 2 substituted for the drill bit.
In this way, my device operates to prevent the weight on the bit 2- ing placed upon the drill bit and if a driller attempts to increase the weight on the drill bit, the circulating water is automatically closed oli'. The packing rings 12 prevent the circulating water from flowing up the barrel past the piston-head.
The ports 26 are preferably inclined downwardly. This reduces the resistance and directs the water i-n `the desired direction. These ports should be made as large as possible. y
Itv is obvious that his circulation cut-oil will operate in an inverted position -as well as in the position in which I have illustrated it. llVhat I claim is:
1. In a circulation shut-off device for drill stems, the combination of a drill stem having an upper'section and a lower section, a plunger connected to one of said sections, a barrel connected to the other of said scctions and having a head which may engage with the .plunger when the upper section of the drill stem is resting upon the lower section, said plunger having a plug on its end -with a port emerging on the side of the plug, and said head having ports therethrough for passing the circulating water down the drill stein, said head having means for covering the side of the plug to close the port through said plunger when the upper section of the drill stein is resting on the lower section.
2. In a circulation shut-0E device for drill stems, the combination of a plunger having means for connecting' the same to the upper section of the drill stem, a barrel receiving the plunger and having means for connecting the same to the lower section of the drill stem, said barrel having a head at its lower end with' a port having a seat with an enlargedmouth at its` upper end, said plunger having a piston ead with means for packing the saine to prevent circulation' water from moving upwardly past the piston head and having a plug tapered at its lower end to come upon said seat, said plunger having a duct extending longitudinally therewith emerging on the side face of the plug for conmore than a predetermined. weight from bep ducting the circulating waterfdown through the drill stem the sidewall of said enlarged mouth operating toclose said duct when Vthe plug is received in the 1nouthsaid plunger and said barrel having a correlated angular construction enabling the plunger to rotate the barrel yand impart rotary movement to the drill stem. f 1
