Abstract
The utility model discloses one and be communicated with the dislocation sleeve channel guide that falls that breaks, it is characterized in that the outside of leading cone body is inlaid with mill teeth, inside has the hydrophthalmia of circulating cooling, the guide rod top of adjustable in length has joint to bore with large milling to be connected, when running in well cementation the sleeve pipe of dislocation of having ruptured or threaded off, when drill bit does not enter hypomere sleeve opening, according to the length of the good guide rod of distance adjustment of the upper and lower two sleeve pipe mouths of pipe, connect a large milling conformed to borehole size above top connection to bore, this instrument lower is to sleeve pipe fracture site, rotation drilling tool and when applying certain the pressure of the drill the leading cone of this instrument and guide rod progressively to enter in lower parts casing pipe and the large milling cone connect above supporting, mill teeth on large milling cone machines away the cement of the same tool sizes that large milling axis of cone line end hole wall solidifies gradually under guide rod and large milling bore the support of top drilling tool, upper and lower two cannula center axis limits form the well of same tool sizes, two borehole axis both two wells are interconnected.
Description
Technical field
The utility model relate to petroleum drilling well workover well inner sleeve break fall and the well misplaced be communicated with in.
Background technology
The solid completion of complete sleeve pipe under oil drilling, under find when drilling through well to occur to rupture or dropout rear lower sleeve pipe drops down onto shaft bottom because waiting solidifying process middle sleeve in well cementation or solid completion.Disconnect because of sleeve pipe or the upper and lower two sleeve pipe mouth of pipe centers not heart in the wellbore after threading off, also not on same borehole axis, below the instruments such as the drill bit entered under from upper sleeve, junk mill cannot enter in sleeve pipe, drilling engineering job abort.
Summary of the invention
For above-mentioned Problems existing, the purpose of this utility model has aimed to provide a kind of connection and to have broken the dislocation sleeve channel guide that falls, the break dislocation sleeve channel guide that falls of this connection has ruptured or the problem of dropout sleeve pipe when run between well cementation and waiting-on-cement, when drill bit does not enter in hypomere sleeve pipe, utilization little leading cone below can enter the principle in hypomere sleeve pipe smoothly, leading cone guides the large milling cone followed up progressively to machine away the cement of its tool axis surrounding set below, on after fracture or dropout, lower two cannula center axis limits progressively clean out with the cement of size well, in connection, lower two sleeve pipes, make the axis place of two wells on an axis, ensure that downhole tool can enter lower parts casing pipe relaying follow-up hole operation.
The purpose of this utility model completes like this:
One is communicated with the dislocation sleeve channel guide that falls that breaks, primarily of leading cone body, mill teeth, hydrophthalmia, lower pin, upper pin, guide rod and top connection composition, the outside of leading cone body is inlaid with mill teeth, inside has hydrophthalmia, guide rod injects in the endoporus of leading cone body, and connect with lower pin and the upper and lower right-angled intersection of upper pin between leading cone body and guide rod, upper and lower pin two electrical pads is welded and fixed pin, top connection is arranged at guide rod top, and the large milling that is connected with above of top connection is bored.
The beneficial effect of advantage of the present utility model and generation is:
1, the utility model structure is simple, is easy to processing, adopts conventional part to assemble, and easy installing/dismounting changes accessory.
2, enter well tool length to fall according to breaking and the lengthening distance misplaced between upper and lower two sleeve pipes or shorten the length of guide rod and regulate, can meet and bore milling and ream the needs of cement between fracture or the two sleeve pipe fractures of threading off, reach the object of UNICOM's upper and lower sleeve tube boreholes, continue drilling engineering operation, avoid well to scrap.
Accompanying drawing explanation
Fig. 1 is the utility model sectional view.
Detailed description of the invention
As shown in Figure 1, one is communicated with the dislocation sleeve channel guide that falls that breaks, primarily of leading cone body 1, mill teeth 2, hydrophthalmia 3, lower pin 4, upper pin 5, guide rod 6, top connection 7 and large milling cone 8 composition, the outside of leading cone body 1 is inlaid with mill teeth 2, inside has hydrophthalmia 3, guide rod 6 injects in the endoporus of leading cone body 1, connect with lower pin 4 and upper pin about 5 right-angled intersection between leading cone body 1 and guide rod 6, upper and lower pin two electrical pads is welded and fixed pin, top connection 7 is arranged at guide rod top, and the large milling that is connected with above of top connection 7 bores 8.
When run in well cementation ruptured or dropout sleeve pipe dislocation problem, when drill bit does not enter hypomere sleeve opening, according to the length of the good guide rod 6 of distance adjustment of the upper and lower two sleeve pipe mouths of pipe, connect a large milling conformed to borehole size above top connection 7 and bore 8, this instrument lower is to sleeve pipe fracture site, rotation drilling tool also applies certain the pressure of the drill pin 4 and upper pin 5 transmits moment of torsion in top connection 7 to leading cone body 1 at present, mill teeth on mill teeth 2 machines away the obstruction that sleeve pipe incision position stops leading cone body 1, the leading cone body 1 of this instrument is made to enter the guiding entering lower parts casing pipe in the sleeve pipe mouth of pipe of bottom as whole instrument, under the guiding of leading cone body 1, guide rod 6 progressively to enter in lower parts casing pipe and supports large milling cone 8, top connection 7 above institute connect large milling cone 8 axis gradually with bottom cannula center axis near time large milling bore mill teeth on 8 and machine away at guide rod 6 and under the support of 8 top drilling tools is bored in milling greatly the cement that the same tool sizes that 8 axis end hole walls solidify is bored in large milling gradually.Along with leading cone body 1, guide rod 6 and large milling cone 8 enter lower parts casing pipe completely, cement on instrument surrounding well wall is just progressively machined away by the cutting teeth on large milling cone 8, and by the mud of circulation in hydrophthalmia 3, the cement drilling cuttings under cutting is carried into well head, large milling cone 8 just forms the well with tool sizes with the axis limit of guide rod 6, both upper and lower two cannula center axis limits formed the well of same tool sizes, and two borehole axis both two wells are interconnected.
It enters well tool length by the lengthening distance between upper and lower two sleeve pipes or shorten the length of guide rod 6 and adjust.
