Mechanical property tests of the matrix powder prepared by the invention show that the bending strength of the matrix powder is increased by 30-40% compared with that of the traditional matrix powder, the impact toughness thereof is increased by 3-4 times than that of the traditional matrix powder, and the abrasion resistance and erosion resistance thereof is increased by 5-10% compared with that of the traditional matrix powder.
Description
Technical field
The present invention relates to a kind of drill bit metallurgical material, specifically be meant a kind of petroleum bit matrix powder that is used to make oil bit.
Background technology
In the oil drilling in modern times, the oil diamond bit has been used as the main recommended products of drilling bit with the high advantage of its drilling efficiency.Along with further developing of petroleum drilling technology, petroleum drilling engineering also proposes higher performance requirement to diamond bit at present, as when requiring drilling well its rate of penetration faster, under the prerequisite of the wearability of guarantee fund's diamond bit own, also further require the cutting wing of diamond bit darker, thinner.Also require simultaneously can effectively cool off at the cutting teeth of high-speed cutting work, and the landwaste of cutting energy rapid drainage etc.But, the carcass powder of present diamond bit is just formed by conventional cast tungsten carbide and the nickel powder system of mixing, the surface quality of its carcass and smooth degree are not high, and also have pore and defective such as loose, therefore make these diamond bits can not well satisfy present actual demand.Therefore, develop a kind of new petroleum bit matrix powder, making its drill bit that is made into can satisfy present various high performance requirements fully is problems that those skilled in the art very urgently solve.
Summary of the invention
The preparation that the objective of the invention is to overcome the carcass powder of present diamond bit is can not the existing drill bit rate of penetration of fine solution fast, the cutting wing is dark, thin, and cutting teeth can not effectively cool off can not rapid drainage with landwaste defective, provide a kind of not only constituent simple, and can be fine satisfy above-mentioned requirements petroleum bit matrix powder.
Purpose of the present invention is achieved through the following technical solutions: petroleum bit matrix powder, mainly form by the material of following percentage by weight,
Cast tungsten carbide powder granularity is 65～400 orders 25～75%,
Alloy tungsten-carbide powder granularity is 65～400 orders 10～60%,
The nickel-base alloy powder granularity is 100～325 orders 10～40%,
The nickel powder granularity is 5～15 micron 2%～8%.
In order better to realize the present invention, the content of described cast tungsten carbide powder is 30～55%, and the content of alloy tungsten-carbide powder is 25～40%, and the content of nickel-base alloy powder is 15～35%, and the content of nickel powder is 3～6%.
The content of described cast tungsten carbide powder is 35～40%, and the content of alloy tungsten-carbide powder is 30～35%, and the content of nickel-base alloy powder is 25～30%, and the content of nickel powder is 3～4%.
The content of described cast tungsten carbide powder is 40～45%, and the content of alloy tungsten-carbide powder is 35～40%, and the content of nickel-base alloy powder is 15～20%, and the content of nickel powder is 4～5.5%.
The content of described cast tungsten carbide powder is 35%, and the content of alloy tungsten-carbide powder is 32%, and the content of nickel-base alloy powder is 29.5%, and the content of nickel powder is 3.5%; Or the content of described cast tungsten carbide powder is 43%, and the content of alloy tungsten-carbide powder is 37%, and the content of nickel-base alloy powder is 15%, and the content of nickel powder is 5%.
The present invention compared with prior art has following advantage and beneficial effect:
(1) bending strength according to the diamond bit matrix powder that makes after traditional component and the percentage by weight mixing only is 550～600MPa, impact flexibility is 2.0～2.5J, and the bending strength of the bit matrix powder that makes after mixing according to component of the present invention and percentage by weight can reach 780～880MPa, impact flexibility even up to 9～11J.Therefore the more traditional diamond bit matrix powder of the present invention is compared, its mechanical property improves a lot, its bending strength performance has improved 30～40% than traditional diamond bit matrix powder, and impact flexibility has improved 3～4 times than traditional diamond bit matrix powder.
(2) with equal pressure with under with equidistant condition, the carcass that traditional diamond drill bit matrix and the present invention are made carries out comparing behind the sandblast 3min, traditional diamond drill bit matrix sheet erosion depth ratio carcass of the present invention surface is dark 6%, and it is wide by 10% that the erosion area is received on traditional diamond drill bit matrix surface ratio carcass of the present invention surface.Therefore, wearability and the abrasion-resistance according to the more traditional diamond drill bit matrix of the carcass that makes after component of the present invention and the percentage by weight mixing improved 5～10%.
(3) according to the carcass that makes after said components of the present invention and the percentage by weight mixing, all more traditional carcass of its surface quality and smooth degree improves a lot, and does not exist pore to reach defectives such as loose, therefore is well positioned to meet present various high performance requirements.
