Description
Technical field
The utility model is related to a kind of novel polycrystalline diamond compact drill bit, belongs to drilling equipment technology neck used for geological prospecting
Domain.
Background technology
Existing compact bit has significant limitation in range, and compact bit is mainly used in mud stone, sand
Rock, based on argillaceous agglutination and the stratum such as cementing loose small particle conglomerate, cream rock and limestone, igneous rock is generally not suitable for using
Compact bit.Diamond-impregnated bit firmly above rock in being primarily adapted for use in.In geological structure complicated and changeable, frequently more
Bit change, can substantially reduce production efficiency, lose time.
Utility model content
The utility model purpose is to provide a kind of novel polycrystalline diamond compact drill bit, mainly by composite sheet cutting element, Buddha's warrior attendant
The compositions such as stone cutting element, the fan-shaped mouth of a river, sludge groove and steel body, additionally it is possible to reach brill well when can change on stratum
The purpose entered, is suitable for various stratum, solves problem present in background technology.
The technical solution of the utility model is：
A kind of novel polycrystalline diamond compact drill bit, comprises composite sheet cutting element, Diamond Cutting tool, the fan-shaped mouth of a river, row's powder
Groove and steel body, described steel body is cylindrical steel body, and composite sheet cutting element and Diamond Cutting tool are crisscross arranged successively in steel body
Outside end, the central axis along cylindrical steel body is in that annular is arranged；Described composite sheet cutting element and Diamond Cutting have it
Between be provided with the fan-shaped mouth of a river；The bottom of described composite sheet cutting element and Diamond Cutting tool is provided with sludge groove.
The quantity of described sludge groove is three.
Composite sheet in described composite sheet cutting element is made using oil piece.
The height of described Diamond Cutting tool is highly identical with composite sheet cutting element.
Diamond Cutting tool is mainly made up of carcass powder and diamond, and carcass powder is mainly made up of Graphene etc., gold
Hard rock is mixed by the diamond of different meshes.In the selection of carcass powder, employ a kind of new material Graphene,
Diamond is mixed using top quality material both at home and abroad and by the diamond of different meshes.So whole carcass just has height
Hardness and superpower wear-resistant, make drill bit operationally ensure that advanced wear does not also have enough resistance to compressions and shock resistance to carcass simultaneously
Intensity, to adapt to bottom hole complicated applied force state.
Composite sheet cutting element and Diamond Cutting have the upper end being located at rigid body, using alternating expression arrangement, have broad spectrum activity special
Levy, can creep in any rock stratum, this makes it possible to overcome drilling efficiency low.In the case of keeping certain efficiency, make drill bit
Can preferably creep in soft or hard rock, the effect of correcting can also be played simultaneously.
It is provided with the fan-shaped mouth of a river between composite sheet cutting element and Diamond Cutting tool, fan-shaped mouth of a river discharge area is big, can
Fully ensure that and flow quantity is rushed by enough, so that rock dust is preferably discharged.
In composite sheet cutting element and Diamond Cutting tool bottom, three sludge grooves are set.Improve the water circulation of bottom hole, more
Discharge beneficial to rock dust.
The beneficial effects of the utility model are：The purpose of drilling when stratum changes, can be reached well, be suitable for
Various stratum, can overcome drilling efficiency low.In the case of keeping certain efficiency, enable drill bit more preferable in soft or hard rock
Ground drilling, can also play the effect of correcting simultaneously.Fan-shaped mouth of a river discharge area is big, can fully ensure that and rush liquor stream by enough
Amount, makes rock dust preferably discharge.
Brief description
Fig. 1 is the utility model structural representation；
In figure：Composite sheet cutting element 1, Diamond Cutting tool 2, the fan-shaped mouth of a river 3, sludge groove 4, steel body 5.
Specific embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
A kind of novel polycrystalline diamond compact drill bit, comprise composite sheet cutting element 1, Diamond Cutting tool 2, the fan-shaped mouth of a river 3,
Sludge groove 4 and steel body 5, described steel body 5 is cylindrical steel body, and composite sheet cutting element and Diamond Cutting tool 2 are crisscross arranged successively
Outside the end of steel body 5, the central axis along cylindrical steel body is in that annular is arranged；Described composite sheet cutting element 1 and Buddha's warrior attendant
It is provided with the fan-shaped mouth of a river 3 between stone cutting element 2；The bottom of described composite sheet cutting element 1 and Diamond Cutting tool 2 is provided with sludge groove 4.
Diamond Cutting tool 2 is mainly made up of carcass powder and diamond, and carcass powder is mainly made up of Graphene etc., gold
Hard rock is mixed by the diamond of different meshes.In the selection of carcass powder, employ a kind of new material Graphene,
Diamond is mixed using top quality material both at home and abroad and by the diamond of different meshes.So whole carcass just has height
Hardness and superpower wear-resistant, make drill bit operationally ensure that advanced wear does not also have enough resistance to compressions and shock resistance to carcass simultaneously
Intensity, to adapt to bottom hole complicated applied force state.
Composite sheet cutting element 1 and Diamond Cutting have 2 upper ends being located at rigid body 5, using alternating expression arrangement, have broad spectrum activity
Feature, can creep in any rock stratum, this makes it possible to overcome drilling efficiency low.In the case of keeping certain efficiency, make brill
Head preferably can creep in soft or hard rock, can also play the effect of correcting simultaneously.
It is provided with the fan-shaped mouth of a river 3 between composite sheet cutting element 1 and Diamond Cutting tool 2.Because of its fan-shaped mouth of a river discharge area
Greatly, reasonable in design, its effect is to ensure that rushes flow quantity by enough, so that rock dust is preferably discharged, is not " burning of bits ".
In each composite sheet cutting element and Diamond Cutting tool three sludge grooves 4 of lower section setting.The current improving bottom hole follow
Ring, more conducively rock dust are discharged.
