Abstract
The utility model discloses a kind of efficient grinding hard rock stratum composite polycrystal-diamond, including diamond layer and the hard alloy supporter bonding with diamond layer；Wherein, described diamond layer includes cutting lay and grinding layer；Described cutting layer thickness scope is 0.5 2.5mm；Described grinding layer thickness range is 2.0 6.0mm.The utility model provides a kind of efficient grinding hard rock stratum composite polycrystal-diamond simple in construction, dual broken rock cubic meter of stone formula；In drilling drilling process, by the use of such composite polycrystal-diamond as wear-resisting cutting element, it realizes cutting, grinding double crushing mode to hard rock stratum, can increase substantially drilling efficiency, cost-effective.
Description
Technical field
The utility model belongs to super-hard compound material technical field, and in particular to oil, gas drilling etc. with instrument and
Equipment, more particularly to a kind of efficient grinding hard rock stratum composite polycrystal-diamond.
Background technology
Composite polycrystal-diamond（PDC）It is that to use selected single-crystal diamond powder and hard alloy be supporter in high temperature
The composite superhard material sintered under condition of high voltage, which overcomes single-crystal diamond and is hit and the damaged problem of easy cleavage and gather around
There is the toughness of hard alloy, be widely used in the fields such as machining, ore mining and oil exploration.With exploration
Theory transformation, innovation, unconventionaloil pool（Such as shale oil, natural gas etc.）Exploration obtains fast development so that complicated deeper
The continuous lifting of the performance needs of drill bit design and its composite polycrystal-diamond that stratum is used, especially drilling competent bed,
Demand of the abrasiveness by force with the bad ground such as tough and tensile interlayer is more harsh.
At present, although the probing for above-mentioned competent bed, abrasiveness by force with the bad ground such as tough and tensile interlayer has been developed
A variety of PDC, such as scrobicula face PDC, taper PDC, but the drilling efficiency of above-mentioned PDC drill bits in use can not still be greatly shortened
Duty cycle, reduction cost of winning.So, it is compound with polycrystalline diamond the utility model proposes a kind of efficient grinding hard rock stratum
Piece.
Utility model content
The purpose of this utility model is that there is provided a kind of efficient grinding hard by improving the diamond layer configurations of composite sheet
Rock stratum composite polycrystal-diamond, this PDC can realize dual broken rock cubic meter of stone formula when in use, increase substantially hard rock stratum
Drilling efficiency.
To achieve the above object, the utility model is using scheme in detail below：
A kind of efficient grinding hard rock stratum composite polycrystal-diamond, including diamond layer and bonding with diamond layer
Hard alloy supporter；Wherein, described diamond layer includes cutting lay and grinding layer；Described cutting layer thickness scope is
0.5-2.5mm；Described grinding layer thickness range is 2.0-6.0mm.
Further, the cutting lay is high-wearing feature polycrystalline diamond layer.
Further, the grinding layer is high self-sharpening polycrystalline diamond layer or hot pressing diamond sinter.
The beneficial effects of the utility model are：The utility model provides a kind of height simple in construction, dual broken rock cubic meter of stone formula
Imitate grinding hard rock stratum composite polycrystal-diamond；In drilling drilling process, made using such composite polycrystal-diamond
For wear-resisting cutting element, it is realized cutting, grinding double crushing mode to hard rock stratum, can increase substantially drilling efficiency, section
About cost.

200, this diamond layer 100 has double-layer structure, and it includes cutting lay 101 and grinding layer 102.
Embodiment 1
The PDC of the present embodiment a diameter of 15.88 mm, is highly 13.2 mm.This PDC diamond layer includes high abrasion
Property polycrystalline diamond layer and high self-sharpening hot pressing diamond sinter, wherein polycrystalline diamond layer thickness about 1.0mm, hot pressing Buddha's warrior attendant
Stone sintering body thickness about 5.0mm.This PDC carries out laboratory contrast test, laboratory contrast test number with traditional PDC with size
According to showing, relative to traditional PDC, this PDC grinding granite rocks efficiency raising about 86%.
Embodiment 2
The PDC of the present embodiment a diameter of 15.88 mm, is highly 13.2 mm.This PDC diamond layer includes high abrasion
Property polycrystalline diamond layer and high self-sharpening hot pressing diamond sinter, wherein polycrystalline diamond layer thickness about 1.0mm, hot pressing Buddha's warrior attendant
Stone sintering body thickness about 5.0mm.This PDC carries out laboratory contrast test, experiment with the impregnated type diamond sinter with size
Room contrast test as shown by data, relative to impregnated type diamond sinter, this PDC grinding granite rocks efficiency improves about 230%.
It the foregoing is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, under the premise of the technical solution of the utility model is not departed from, some modifications or equivalent substitute can be also made, this is regarded
For protection category of the present utility model.
