GUIDE FOR SIDE TRACKERS.
AApplication meu July e, 1925. serial my. 41,655.
This invention relates to a device itor use in oil well drilling and more especially in side tracking operations. In drilling wells, tools often become lost as well as other parts in the bottom of l.the hole and lodge therein so that removal by the usual methods cannotl be effected. Such lost parts are commonly termed fish and are hereafter referred to by that name. In some of such instances, means are employed to drill around the fish and advance the hole. Such operations are known as side tracking and have heretofore been effected by continuing the drilling depending upon'the ish to deflect the boring toolito one side. 'In some instances, the ordinary drilling bits used for this purpose have been changed to suit the individual choice of the driller. A special tool for side tracking is disclosed in my copending ,applicatlon for side tracking tool7 Serial No. 13,209, tiled March 5, 1925, and the embodiment of the present invention disclosed herein shows and describes a tool of this character as employed withthis type of side tracker. The primary object of this inventionis to provide a side tracking tool guide .which will positively direct the tool laterally of the ish, which will oder a minimum of resistance to drilling, is economical, easy to manipulate, and can be placed quickly in position for use. Another objecty of this invention is to provide' a device of the character described, which may be attached to and form the lower end of an lordinary string of casing.
lThese objects together with other objects and corresponding accomplishments are obtained by means Iof the embodiment of my invention illustrated in the accompanying drawing, in which:
Fig. 1 is a side" elevationY of the guide showing a fragment of the casing to which it is attached at the upper end and a fragment of a ish at the lower end; Figs. 3, 4, 5, and 6 are sections as seen on the lmes correspondingly numbered in 'F1g1. Re-
ferring more particularly to the drawing, a fragment of the original casing 1n the hole is indicated by 7, and 8 indicates a fish therein. When it is found impossible to dislodge the fish bythe ordinary fishing methods, the casing cutter is lowered 1nthe hole .and the casing severed as close to the fish as possible, that is, if the casingcannot be entirely pulled.
A string of casing is now lowered in the hole. Attached to the last'jointof the casing indicated by 9 is the guide for` the side tracklng tool. This guide `has a tubular upper end externally threaded sol as to receive a coupling collar 10. The upper end of the guide is of tubular form and may be conveniently made of several sections or joints of casing welded together to form a relatively long member, this tubular body being` indicated by l11. The wall thereof is cut away at the upper portion as indicated by 12 to form an exit for the side tracking tool. The cut extends substantially `into one-half of the tube, and a. tapered slot is cut therein ending as indicated by 13 'adjacent the lower end ot the body.
Secured over the slot and to the body is a concave seat 14 against which the side tracking tool may slide. The seat is provided with perforations `15 to permit the egress of Huid or liquid whichmay be trapped in the chamber orguide during lowering in the hole. Threaded onto the lower end of the guide is a casing shoe 16 having a perforated plate 17 guarding the chamber. The
tion,cementing or any other desired operation may beperformed. During the lowering, the hole being filled with slush, the latter enters the chamber in the side tracker guide'4 and may readily pass outwardly through the perforat-ions 15 thereby adding no resistance to the lowering of the casing.l
The casing and guide having been positioned ready for the drilling operation, the side tracker 19 is lowered passing through the exit 12 and being diverted laterally in its vadvance until it has been disposed at the side of the original hole. The hole will thus be side tracked advancing around the side of the fish.
It will be noted that the guide is formed as a continuation of the lower end of the string of casing. It is obvious thatlalthough it has been described as builtup of several sections of casing, it maybe formed of an integral piece or in any other convenient manner.
Vhat I claim is:
l. A guide for side tracking tools cornprising a hollow body havinga tubular upper end with a lateral exit opening and a perforate seat extending in front of said opening and inclined outwardly along the length ot said body to the end of'the outer periphery thereof, said body having a tubular open lower end and said seat having perforations for through. e
2. A guide for side tracking tools comprising a hollow body having externally threaded open ends, said body being tubular -and provided with a lateral exit opening,
and a perforate concave seat extending in front of said opening and inclined outwardly along: the length of said body to the outer periphery thereof.
In witness that I claim the foregoing I have hereunto subscribed my name this 26th day oi? June, 1924.
