Abstract
The invention discloses a novel drilling and reaming tool. The novel drilling and reaming tool is characterized in that a side water hole for circulation and cooling are formed in a guide cone, and a tapered mill body is connected with the guide cone on the lower portion and an upper connector on the upper portion through a screw thread; when sleeve pipes are fractured or released in well cementing and a drill cannot access to an opening of the lower sleeve pipe, the tapered mill body can be adjusted by increasing or decreasing section number and length of the tampered mill body according to the distance between the two openings of the sleeve pipes; the guide cone of the novel drilling and reaming tool is inserted into the opening of the lower sleeve pipe to serve as a supporting point, and guided by the taper of the guide cone to enter the opening of the sleeve pipe gradually when a drill tool is rotated and certain bit pressure is exerted on the drill tool, an axis of the tapered mill body gradually gets closer to the center of the lower sleeve pipe, and supported by the guide cone, milling teeth embedded in the tapered mill body gradually cut off cement solidified on a wall of a well beside the guide cone and an axis of the upper connector, and the cement is same in size with the tool; a well bore same in size with the tool forms beside the guide cone and the axis of the upper connector, in other words, the well bores same in size with the tool are formed beside the center axis of the upper and lower sleeve pipes, and the axes of the well bores, namely the two well bores, are mutually communicated.
Description
Technical field
The present invention relates to when oil drilling is cemented the well casing failure or thread off after will upper and lower two unidimensional wells in sleeve pipe central axis limit cement clean out two casing axis be on the line substantially, the assurance downhole tool can enter in the lower parts casing pipe.
Background technology
The solid completion of complete sleeve pipe under oil drilling, lower drilling through found in the well process to drop down onto the shaft bottom at well cementing process middle sleeve fracture or dropout rear lower sleeve pipe.Because upper and lower two sleeve pipe mouth of pipe centers after sleeve pipe disconnection or the dropout are not in the well center, also not on an axis, in the sleeve pipe, the drilling engineering operation was ended below the instruments such as the drill bit that is lowered to from upper sleeve, junk mill can't enter.
Summary of the invention
Problem for above-mentioned existence, purpose of the present invention has aimed to provide a kind of Novel drill plug hole reaming tool, this Novel drill plug hole reaming tool is to have ruptured in the well cementation or the problem of dropout sleeve pipe when running into, when drill bit does not advance the hypomere sleeve pipe, utilize concentrically ringed principle progressively to machine away the cement that solidifies around its tool axis, fracture or on after threading off, the cement of the unidimensional well in lower two sleeve pipe central axis limits progressively cleans out, in the connection, lower two sleeve pipes, make the axis place of two wells on an axis, guarantee that downhole tool can enter lower parts casing pipe relaying follow-up hole operation.
The objective of the invention is to finish like this:
A kind of Novel drill plug hole reaming tool mainly by leading cone, side hydrophthalmia, mill cone body, top connection and form.Have circulation on the leading cone, the side hydrophthalmia of the usefulness that cools, mill cone body and the leading cone of bottom, the top connection screwed connection on top.
The beneficial effect of advantage of the present invention and generation is:
1, the present invention is simple in structure, be easy to processing, adopt conventional part assembling, easily installing/dismounting is changed accessory, entering the length that well mills the cone body can adjust according to the distance of fracture between the sleeve pipe, can satisfy and bore the needs that milling reams cement between the two sleeve pipe fractures that rupture or thread off, reach the purpose of UNICOM's upper and lower sleeve tube boreholes, continue the drilling engineering operation.
Description of drawings
Fig. 1 is sectional view of the present invention.
The specific embodiment
As shown in Figure 1, a kind of Novel drill plug hole reaming tool mainly by leading cone 1, side hydrophthalmia 2, mill cone body 3, top connection 4 and form.Have the side hydrophthalmia 2 of circulation, the usefulness that cools on the leading cone 1, mill cone body 3 and use screwed connection with the leading cone 1 of bottom, the top connection 4 on top.
In running into well cementation, ruptured or the problem of dropout sleeve pipe, when drill bit does not advance the hypomere sleeve opening, foundation is the good length of distance adjustment of the two sleeve pipe mouths of pipe up and down, the leading cone 1 of this instrument is injected in the sleeve pipe mouth of pipe of bottom as the strong point, rotation drilling tool and when applying certain the pressure of the drill under the guiding of leading cone 1 tapering leading cone progressively enter in the sleeve opening of bottom, the axis that mills cone body 3 is just close with lower parts casing pipe center gradually, mills the mill teeth of inlaying on the cone body 3 machines away the same tool sizes that leading cone 1 and top connection 4 axis end hole walls solidify gradually under the support of leading cone 1 cement.Along with the cone of leading cone 1 enters lower parts casing pipe fully, cement around the instrument on the borehole wall is just machined away by the cutting teeth of this instrument, and by in the side hydrophthalmia 2 circulation mud the cutting under the cement drilling cuttings be carried into well head, leading cone 1 just forms the well with tool sizes with top connection 4 axis limits, both upper and lower two sleeve pipe central axis limits formed the well with tool sizes, and two borehole axis both two wells are connected.
It enters well tool length can increase or cut joint number and the length of milling cone body 3 according to the distance between two sleeve pipes up and down and adjust.
