Description

LGELMQ June 7, 1927.
M. M. KINLEY APPARATUS FOR PLUGGING wELLs led June 4. 1926 A TTORNE Y Patented' `June 7, 1927.
. UNITEB APPARATUS non newsemewnLLs.
Application led June 4,
My invention relates to a method of and apparatus for plugging wells and has tor its principal object to shut off the flow ot water to a well from which production is to'be n soughtt'rom sands'above the water flowing stratum.
In some instances wells which have been drilled through oil bearing sands into water strata or into oil strata which have gone to 1o water after producing periods, are plugged to shut ott` the water from the lower levels and permit production from the upper sands.
As such plugging must be effected'. at a depth of from a few .hundred to several thousand feet, and Within a hole of but a few inches in diameter, itis diiicult if not impossible to accurately determine the exact point Where the plug shouldbe located, and to then locate and seal the plug in the well.
It is, therefore, one of the objects of my invention to provide a plug which may be easily and accuratel located in a well and which, when locate may be sealed to the wall of the well in a manner to effectively prevent flow ofwater to the portion of the well above the plug.'
4It is also an object of my invention uitprovide a method and apparatus which will not require reinstallation of heavy reeling equipment for its operation but which may e employed with a portable reel immediately upon removal of the rods and pump.
In accomplishing these obects I employ the method and apparatus ereinafter de-4 scribed by reference to the accompanyin drawings, wherein a preferred form o structure is illustrated arid wherein Fig. 1 is a vertical section of an oil wel] within which a plugging apparatus con@ structed according to my invention is being lowered;
Fig. 2 is a vertical section ofthe lower, uncased portion of a well, showing water and gas bearing sands, and showing the plugging apparatus broken away for bett/er illustration.
Fig. 3 is a view of the well as it appears when plugged.
50 liter'erring more in detail to the drawings:
1 desi etes a well hole which has been vdrilled rough earth 2 (Fig. 1) and oil bearing sand 3, into water sand 4 Figs.2 vand 3 the upper portion of the we l being provi ed with the usual casing 5. 6 designates a container, preferably of the greatest 1926. seriai Na. 113,712.
possible diameter that will permit it to pass ATET OFFICE! through the well hole without stoppage, so
that the least possible expansion of the container -will carry it into contact with the vwall of the well, and of the lightest practicable gauge of sheet metal, so that the wall of the container may be completely disrupted under the conditions presently stated.
Located within and forming the bottom pfthe container 6 is a plug 7 of expansible and non-corrodible material, preferably lead, having an upwardly-opening chamber or pocket 8 of a size to contain suflicient exy plosive for expanding the plug against the walland disrupting the container to' sever it so that the upper portion may be removed from the well. The `chamber or pocket 8v is filled with explosive material 9 and embedded in said material is a fulminating cap 10. Connected with the `cap 10 y is a circuit wire 11, the mate 12 of which `is" grounded on the' container 6; the two wires being extended through the container asa cord 13, which is attached to the bale 14 and serves as a cable for letting in the container. V The cord 13 may vbe-run over the usual pulleys and' connected to the usual winding drums (not shown) and the circuit wires 4may be connected with -the usual battery through the` usual switch, none of which latter parts are illustrated, as they may be of forms employed in ordinary practice,'and their detail structures form no part of the present invention.
Filling the container aboutthe plug 7 is a quantit of cement 15, preferably in -neat mixture orm, andsuspended from the container, preferably in a burlap bag 16` and by abale 17 partly embedded in the` lead plug, is la mass of fibrous packing materia preferably oakum.'
Assuming that the point for location of the plug has been ascertained from the log of the well, and that the apparatus has been constructed and assemble' a's described, plugging of the well-is effected as follows:
The container is let into the well to the proper point and held suspended while the charge of explosive is fulminated by closing the battery circuit through the switch.
When the charge is exploded, it expands thevblowing the upper portions ot the container up into the well hole and freeing the cement so that the latter ows out into the well and settles onto the plug in a mass which, when set, forms a seal supplementing that of the lead plug in preventing flow of water from the water sands into the well.
With vthe plug set as described, accumulation of water pressure beneath the plug forces the oakum up into crevices about the plug to seal any opening that may be occasioned by irregularities 1n the surface of the 'plug or wall of the well..'
The upper portion of the containerinay be removed fronrthe well with the letting in and fulmi/nating cord to leave ythe well free for the installation of pumps.
What I claim and desire to secure by -Letters Patent is:
. 1. Apparatus for plugging wells comprising a rupturable container,` a plug of expansible material in the lowerportion of the container providing an upper space for sealing material and having a chamber for containing a charge of exp1osive,and fulminating means comprising a cap located in said chamber. v l
2. Inapparatus foriplugging wells, a container, a plugof expansible material at the bottom of the container having a chamber for containing `afjcharge of explosive, the
container extending beyond the plug to retaln a quantity of sealing material, .and means for fulminating a charge of explosive in the plug chamber.
3. In an apparatus for plugging wells, a container, a plug of expansible material at the bottom of the container having a chamber for containing a charge of explosive, the container extending beyond the plug to retain a quantity of sealing material, a fulminating cap in the explosive chamber, and means for letting in the container comprising wires having circuit connection with said cap.
4. In an apparatus for plugging Wells, a
container, a plug ofexpansible material at the bottom of the container having a chamber for containing a charge of explosive, the container extending beyond the plug to retain aV quantity of sealing material, 'and a
