Abstract
The invention discloses a blank formula for a multi-performance oil well drill bit and a preparation method thereof, in particular, relates to the field of tools for petroleum, coals and geologic well drilling, and relates to a manufacturing method of a metal powder metallurgy material. The blank formula for the multi-performance oil well drill bit is characterized by being prepared through a blank mixture and a hard alloy ball according to a weight ratio of 2: 1; the blank mixture is prepared by the following components in percentage by weight: 30-50% of casting tungsten carbide, 10-60% of tungsten carbide, and 5-43% of atomization nickel powder; and the casting tungsten carbide is prepared by different particle sizes. W2C powder is prepared by different particle sizes and scientific ratio; WC powder with a certain ratio is added to improve the blank performance; a proper amount of atomization nickel powder is added to improve the flowing performance and the toughness of the formula; and a hard alloy is added in the prepared formula for mixing and grinding, so that the powder is refined and homogenized.
Description
Technical field
The present invention relates to oil, coal, geological drilling field of tool, also relate to metal powder
The manufacture method of the metallurgical material powder in end, is specifically related to the matrix formula of a kind of many performances drill for oil well
And preparation method thereof.
Background technology
The carcass of early stage drill bit does not has formula, only buys 60 to 200 mesh at cemented carbide works
Cast tungsten carbide (W2C) powder, loads in drill bit grinding tool, adds alloy block sintering and forms,
W2C powder size is that nature is made at random, does not has rule, and dusty material is the most single, itself
Performance is the simplest, and the bit matrix performance gone out therefore sintered is relatively low, when drill bit wing lengthens
After, usually occur when drill bit is organized altogether collapsing block and the situation of the breaking wing, have a strong impact on wellbore construction
Quality and speed.
Therefore, develop the matrix formula of a kind of high intensity, high impact toughness, be that existing field is needed badly
The problem solved, be substantially reduced drill bit falls block and the situation of the breaking wing.
Summary of the invention
The technical problem to be solved is to provide the tire of a kind of many performances drill for oil well
Body formula and preparation method thereof, it is intended to solve the defect of above-mentioned matrix formula: bending strength is low, anti-
The defects such as poor impact toughness, solve easily to fall block and the situation of the breaking wing.
For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of many performances
The matrix formula of drill for oil well, it is characterised in that: be by carcass batch mixing and sintered carbide ball with
The weight ratio proportioning of 2:1 forms, and described carcass batch mixing is to be joined by weight percentage by following compositions
Ratio forms: cast tungsten carbide 30～50%, tungsten carbide 10～60%, atomization nikel powder 5～43%；Institute
Stating cast tungsten carbide to be formed by different grain size proportioning, granularity components by weight percentage is:
Further technical scheme also resides in, and its preparation method is as follows:
(1), by above-mentioned weight proportion, varigrained cast tungsten carbide is prepared, then press
Above-mentioned weight proportion adds tungsten carbide and atomization nikel powder is configured to carcass batch mixing；
(2), join with the weight of 2:1 with sintered carbide ball by the carcass batch mixing in step (1)
Ratio weighs required sintered carbide ball；
(3), step (1), the carcass batch mixing of (2) gained and sintered carbide ball are together loaded
In the charging basket of three-dimensional material mixer, with the rotating speed batch mixings 6 of 20～60 revs/min per minute～12 hours；
(4), step (3) gained material is put into drying baker, with 80～100 DEG C of insulations 2～4
The carcass raw material making many performances drill for oil well is i.e. obtained after hour.
Use and have the beneficial effects that produced by technique scheme:
The bending strength of bit matrix improves 40% than conventional formulation, and toughness improves
105%, solve and easily fall block and the situation of the breaking wing, and matrix formula make its more refine and
Homogenization.
Detailed description of the invention
Below the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that
Described embodiment is only a part of embodiment of the present invention rather than whole enforcement
Example.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creativeness
The every other embodiment obtained under work premise, broadly falls into the scope of protection of the invention.
Elaborate a lot of detail in the following description so that fully understanding the present invention, but
It is that the present invention can also use other to be different from alternate manner described here to implement, this area
Technical staff can be similar popularization, the therefore present invention in the case of intension of the present invention
Do not limited by following public specific embodiment.
The formula of the present invention is with the weight ratio proportioning of 2:1 by carcass batch mixing and sintered carbide ball
Forming, described carcass batch mixing is to be formed by following compositions components by weight percentage: casting carbonization
Tungsten 30～50%, tungsten carbide 10～60%, atomization nikel powder 5～43%；Described cast tungsten carbide is not by
One-size proportioning forms, and granularity components by weight percentage is:
The formula preparation method of the present invention is as follows:
(1), by above-mentioned weight proportion, varigrained cast tungsten carbide is prepared, then press
Above-mentioned weight proportion adds tungsten carbide and atomization nikel powder is configured to carcass batch mixing；
(2), join with the weight of 2:1 with sintered carbide ball by the carcass batch mixing in step (1)
Ratio weighs required sintered carbide ball；
(3), step (1), the carcass batch mixing of (2) gained and sintered carbide ball are together loaded
In the charging basket of three-dimensional material mixer, with the rotating speed batch mixings 6 of 20～60 revs/min per minute～12 hours；
(4), step (3) gained material is put into drying baker, with 80～100 DEG C of insulations 2～4
The carcass raw material making many performances drill for oil well is i.e. obtained after hour.
The present invention is to W2C powder uses different grain size, the proportional arrangement of science；Add a definite proportion
The WC powder of example, improves tyre-e/or performance；Add and be atomized nikel powder in right amount, improve the stream of formula
Dynamic performance and toughness；To the formula made, add hard alloy mix grinding, make powder refinement with equal
Homogenize.
Shown in its performance of the present invention and old formula and industry standard contrast see table:
Various aspects of performance the most of the present invention is all far above industry standard and old carcass
Performance formula.
The bending strength of bit matrix improves 40% than conventional formulation, and toughness improves
105%, solve and easily fall block and the situation of the breaking wing, and matrix formula make its more refine and
