A kind of main new material bridge plug based on composite material, supplemented by metal material of bridge plug, conventional junk mill is for bridge plug lower part
Clast and deposit can not clean in time, bore mill and drilling efficiency is lower.
Summary of the invention
In order to overcome, existing brill mill and drilling efficiency are lower, ask what bridge plug lower part clast and deposit can not clean in time
Topic, the present invention provide a kind of latus rectum class bridge plug special efficient junk mill.It is suitable for having the brill for boring bridge plug fastly compared with big orifice milling demand.
The fast junk mill and drilling efficiency for boring bridge plug can be greatly improved.
The technical solution adopted by the present invention are as follows:
A kind of latus rectum class bridge plug special efficient flat-bottom grind shoes, including ontology, six valve milling italics, YG hard alloy blocks and anti-
To guiding milling body, ontology one end connection is reversed to be oriented to milling body, the reversed guiding milling body and six valve milling italics
Connection；7 channels for liquid circulation are arranged at six valve milling italic bottoms, and equally distributed six channels of annular are milling water
Eye, 1 channel at middle part are to rinse hydrophthalmia；Uniformly paving welds multilayer YG hard between six valve milling italics and reversed guiding milling body
Alloy block.
Six valve milling italic bottoms are provided with eccentric flushing hydrophthalmia.
YG hard alloy blocks cross section is at equilateral more diamond shapes.
Uniformly paving welds 4-6 layers of YG hard alloy blocks between six valve milling italics and reversed guiding milling body.
YG hard alloy blocks hardness is HRA91.
The six valves milling italic upper end is in the lotus shape of six valves, and lower end is the cylinder of inclined bottom surface；The reversed guiding
Milling body is the stage body cooperated with six valve milling italic lower end inclined-planes.
The invention has the benefit that
The present invention is to provide a kind of special efficient junk mill for boring bridge plug fastly for latus rectum class.It is suitable for larger logical
The brill of the fast brill bridge plug of diameter mills demand, and the fast junk mill and drilling efficiency for boring bridge plug can be greatly improved.
It spreads using flat-bottom grind shoes and uniformly and welds (4-6 layers) of multilayer more diamond shape hard alloy stereo blocks with multidirectional acute angle,
Milling effect is improved by comprehensive functions such as cutting, grinding, tearings, the high-velocity fluid that hydrophthalmia flows out is rinsed from junk mill bias and passes through
Bridge plug central passage directly rinses bridge plug bottom clast and deposit, eliminates influence of the basic sediment to mill is bored, meanwhile, because of it
Bias design, can also realize all standing to milling face.The junk mill can be realized to bridge plug seal rubber, aluminium alloy and nonmetallic multiple
The quick drill of the components such as condensation material, which mills, to be required, while bridge plug bottom being kept to clean, and improves the drilling efficiency between two bridge plugs.

Specific embodiment
Embodiment 1:
In order to overcome, existing brill mill and drilling efficiency are lower, ask what bridge plug lower part clast and deposit can not clean in time
Topic, the present invention provide a kind of latus rectum class bridge plug special efficient junk mill as shown in Figure 1, Figure 2, Figure 3, Figure 4.It is suitable for having larger
Latus rectum bores the brill milling demand of bridge plug fastly.The fast junk mill and drilling efficiency for boring bridge plug can be greatly improved.
A kind of latus rectum class bridge plug special efficient flat-bottom grind shoes, including ontology 1, six valve milling italics 2, YG hard alloy blocks 5
With reversed guiding milling body 6, the reversed guiding milling body 6 of 1 one end of ontology connection, the reversed guiding milling body 6 and six valves
Milling italic 2 connects；7 channels for liquid circulation, equally distributed six channels of annular are arranged at six valve milling italics, 2 bottom
For milling hydrophthalmia 3,1 channel at middle part is to rinse hydrophthalmia 4；It is uniformly spread between six valve milling italics 2 and reversed guiding milling body 6
Weld multilayer YG hard alloy blocks 5.
It spreads using flat-bottom grind shoes and uniformly and welds more diamond shape hard alloy stereo block, that is, YG hard that multilayer has multidirectional acute angle
