Description

A kind of new bridge plug milling shoe
Technical field
The utility model belongs to oil equipment field, more particularly, to a kind of new bridge plug milling shoe.
Background technology
Junk mill operation principle is that the carbide button of its bottom bites shaft bottom by milling thing under the action of the pressure of the drill, in certain moment of torsion Effect is lower to form grinding, and the chip of milling is by sink with circulation well liquid band upper ground surface.Domestic and international junk mill huge number at present, but It is the absence of targetedly designing, many junk mill designs do not take into full account underground by the material of milling thing, cutting chip state, row Bits require and bore mill speed etc., and milling speed is slow, effect is poor.
The content of the invention
Problem to be solved in the utility model is to provide a kind of new bridge plug milling shoe, is especially suitable for user to after to milling Chip cleared up.
In order to solve the above technical problems, the technical solution adopted in the utility model is:A kind of new bridge plug milling shoe is provided, is wrapped Junk mill body is included, junk mill body is cylindrical structural, and junk mill body one end is provided with a baffle, and junk mill body interior is radially opened Equipped with a long tube, the other end of long tube from junk mill body is pierced by, and the other end of junk mill body is provided with a connector, junk mill body It is radially equidistant on lateral wall to offer some diversion trenches, some hydrophthalmias, and hydrophthalmia and water conservancy diversion are offered on the lateral surface of baffle Groove corresponds, and hydrophthalmia is corresponding with diversion trench to be connected, and junk mill body interior offers some branch pipes, one end of each branch pipe with Long tube connects, and the other end of each branch pipe connects one to one with each hydrophthalmia respectively, and baffle lateral surface is provided with some cut Block, baffle lateral surface are uniformly provided with some hard alloy blocks, stent are provided with the inside of long tube, and stent is perpendicular with long tube, branch There is a splitter along junk mill body radially installed on frame, baffle direction is directed toward in splitter end, and splitter afterbody is provided with one Vibrating device.The junction of long tube and each branch pipe is provided with the cavity of a spheroid shape.A diameter of 8-10mm and five of hydrophthalmia, and It is 30 ° with junk mill body axis angle.
In use, stripping and slicing is stretched into underground by user, is cut soil and is fixed, then junk mill body side is some Diversion trench enters the water with chip in long tube by hydrophthalmia, easy to collect and handle.
The utility model has the advantages and positive effects of:Due to the adoption of the above technical scheme so that user is to mill The processing of the chip produced after milling becomes more convenient, has efficient milling efficiency to import bridge plug so that welding more firmly may be used Lean on, improve milling efficiency;And the utility model has simple in structure, easy to maintenance, it is excellent that processing cost is low, production efficiency is high etc. Point.
