Background technology
Oil field is in drilling process, and down-hole often occurs needing to use in the drilled trouble of lost tool in hole that removes of needs or drilling well then needing the drilled cement plug, bridging plug etc. that remove.Meet at present and state operating mode, the common junk mill of usual employing or PDC drill bit are removed, common junk mill is at the random surfacing hard alloy particle of junk bit body end face, be that whole plane contacts with junk in milling, belong to abrasiveness milling, though processing is simple, cost is low, but milling efficiency is low, easily produces mirror damage; PDC drill bit belongs to milling milling, and milling efficiency is higher, but processing and manufacturing location is complicated, and cost is high, and be not suitable for irregular top of fish, the scope of application limits to some extent.
Summary of the invention
The purpose of this utility model is: in order to meet high efficient and reliable ground auger milling bridging plug, cement plug, the needs of the mid-strength material components such as trouble of lost tool in hole, further saving construction period, solve common junk mill milling bridging plug efficiency low, the difficult problem that PDC drill bit processing cost is high, the combined cutting edges speed carrying cutting angle that spy provides a kind of self-sharpening strong bores tooth, random heap can be realized be welded in junk bit body surface and all can keep sharp keen cutting ability, multiple spot can be realized cut, many ribs cut and all standing, it is simple that the design of this profile of tooth makes junk bit both have the processing of common junk mill, the advantage that cost is low, also there is the milling milling function of PDC drill bit, the advantage that milling efficiency is high.
To achieve these goals, the technical scheme that the utility model adopts is: design a kind of combined cutting edges speed carrying cutting angle and bore tooth, this speed bores tooth by cemented carbide powder compression molding, and its profile is be combined with each other by multiple plane and forms.Speed bores tooth ends (1) in windmill, is formed by four plane combinations at an angle to each other.Speed is bored tooth cutting rib (3) and is bored the crossing rib of flank flat for end horizontal face (5) with speed, and end defines four and cuts rib (3), and speed bores tooth both ends feature symmetry; This speed bores tooth has four in rotational symmetric side area (2), and speed is bored each side area of tooth (2) and is made up of two side planes at an angle to each other, defines four altogether and cuts incline (4).
Described speed bores the face of tooth ends (1), arises to cut rib (3) and be 3 ° of-10 ° of angles with end horizontal face, terminates in the plane place that the recessed rib in corresponding both sides is formed.
Described speed is bored four, tooth and is cut incline (4), and during horizontal positioned, two inclines (4) of the same side edge regions (2) are contour.
Described speed is bored four, tooth and is cut incline (4), and intersect perpendicular to end horizontal face (5) and by two side planes and form, two form the side plane angle cutting incline (4) is 40 °-60 °.
Described speed is bored flank edge regions (2) and is made up of the side plane that two are mutually 130 °-140 °, and wherein side plane bores tooth axial plane (6) angle with speed is 10 °-30 °.
The utility model compared with the prior art, there is following beneficial effect: the advantage of common junk mill and PDC drill bit organically combines by the utility model, achieves and abrasiveness milling is converted to milling milling, simplify manufacturing procedure, reduce processing cost, effectively improve milling efficiency; Profile of tooth designed by the utility model, is formed by multiple Planar Compound, increases cutting point and cuts rib, can realize multiple spot cutting, the cutting of many ribs and all standing; It is based on random principle, built-up welding or be cast in junk bit body end upper surface, all has sharp keen cutting angle, has good self-sharpening, extend the application life of drill bit, saved drilling cost in any cutting plane.

In figure: 1-speed bores tooth ends, 2-speed bores flank edge regions, and 3-cuts rib, and 4-cuts incline, 5-end horizontal face, and 6-speed bores tooth axial plane.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in figure 1, Fig. 2, Fig. 3, a kind of combined cutting edges speed carrying cutting angle bores tooth, and this speed bores tooth by cemented carbide powder compression molding, and its profile is be combined with each other by multiple plane and forms.Speed bores tooth ends (1) in windmill, formed by four plane combinations at an angle to each other, speed bores the face of tooth ends (1), arise from and cut rib (3) and with end horizontal face (5) in 3 ° of-10 ° of angles, terminate in the plane place that the recessed rib in corresponding both sides is formed; Speed is bored tooth ends cutting rib (3) and is bored the crossing rib of flank flat for end horizontal face (5) with speed, and end defines four and cuts rib (3); Speed bores tooth both ends feature symmetry.This speed bores tooth has four in rotational symmetric side area (2), and speed is bored each side area of tooth (2) and is made up of two side planes at an angle to each other, defines four altogether and cuts incline (4); During horizontal positioned, two cuttings incline (4) of the same side edge regions (2) are contour; Speed is bored four, tooth and is cut incline (4), and intersect perpendicular to horizontal plane (5) and by two side planes and form, two side plane angles are 40 °-60 °; Speed is bored flank edge regions (2) and is made up of the side plane that two are mutually 130 °-140 °, and wherein side plane bores tooth axial plane (6) angle with speed is 10 °-30 °.
Open one group of groove at junk bit body end face, take the mode of random built-up welding or casting that the combined cutting edges speed carrying cutting angle is bored tooth and be fixed in junk bit body end face, formed and bore milling work plane.Use the junk bit of this profile of tooth to be applicable to bore milling bridging plug, cement plug, trouble of lost tool in hole etc., be specially adapted to bore the mid-strength material components such as milling composite material, cast iron, soft metal.The advantage of common junk mill with PDC drill bit organically combines by the design of this profile of tooth simultaneously, achieves and abrasiveness milling is converted to milling milling, simplify manufacturing procedure, reduce processing cost, effectively improve milling efficiency; Every tooth has multiple cutting point or cuts rib, can realize multiple spot cutting, the cutting of many ribs and all standing; It is based on random principle, built-up welding or be cast in junk bit body end face, all has sharp keen cutting angle, has good self-sharpening, extend the application life of junk bit, saved drilling cost in any cutting plane.
