Abstract
The invention discloses an abrasion proof material for an abrasion proof layer of a drill pipe joint, wherein the abrasion proof material is a diamond composite material which consists of polycrystalline diamond, cast tungsten carbide and Cu-Co-Ni alloy. The abrasion proof material of the drill pipe joint has extremely strong abrasion resistance, can well prevent abrasion of the drill pipe joint in a strong abrasive stratum, has weak capability in abrasion of an iron-based metal material, has excellent protecting effect on a sleeve, has small friction coefficient, and has small friction resistance in rotating process.
Description
Technical field
The present invention relates to a kind of anti-wear material for drill pipe joint, more particularly, the prescription that relates to a kind of diamond composite material anti-wear material for drill pipe joint, diamond composite material anti-wear material for drill pipe joint among the present invention can be used for the abrasionproof of joint of petroleum drill rod in strong abrasive formation, reduce drill pipe sub simultaneously telescopic is worn and torn, reduce frictional resistance.
Background technology
Conventional at present anti-wear material for drill pipe joint is ceramic-metal composite or chromium carbon compound alloy, and purpose is to prevent the drill pipe sub wearing and tearing in the drilling rod rotary course, reduce drill pipe sub simultaneously telescopic is worn and torn, and plays the effect of protective casing.Conventional anti-wear material for drill pipe joint can realize preventing the effect of drill pipe sub wearing and tearing and protective casing in simple, the general abrasive formation of hole structure, but in the stronger stratum of abrasive property or in the well of hole structure than complexity, the wear resistance of conventional anti-wear material can not satisfy the working conditions requirement, the drill pipe sub serious wear, the drilling rod life-span obviously reduces; Conventional anti-wear material is also more serious to the telescopic wearing and tearing simultaneously.The present invention relates to a kind of diamond composite material anti-wear material for drill pipe joint, the material of invention not only has extremely strong wear resistance, strengthens the wear resistance of anti-wear material for drill pipe joint; simultaneously to a little less than the telescopic wearing and tearing ability; sleeve pipe is had good protective action, and frictional coefficient is little, reduces friction resistance.
The abrasive manner of joint of petroleum drill rod is mainly abrasive wear, and the ability that material bears abrasive wear increases with the increase of material hardness.Diamond is the hardest material in the present all material, as anti-wear material for drill pipe joint, can improve the ability of drill pipe sub abrasive wear resistance with diamond, increases substantially the life-span of drill pipe sub.Diamond is the allotropic substance of carbon simultaneously, can be converted into carbon under certain temperature, pressure and catalysis.The interatomic distance and the diamond of ferro element are close, are the catalyst materials that carbon and diamond allotropic substance transform, and when also both friction had taken place for diamond and ferrous alloy, diamond can rapid greying.Sleeve pipe is a ferrous alloy, and when friction took place for diamond and sleeve pipe, the diamond of contact site produced the allotropy conversion, formed graphite and played lubrication, can not cause telescopic is worn and torn.In addition, adamantine frictional coefficient is minimum in present all material, can reduce the friction resistance of drilling rod in rotary course.Therefore diamond composite material anti-wear material for drill pipe joint has the effect that prevents drill rod abrasion, protective casing, reduction wearing and tearing.
Summary of the invention
The object of the present invention is to provide a kind of diamond composite material anti-wear material for drill pipe joint that has, this anti-wear material can satisfy joint of petroleum drill rod wear-resisting in strong abrasive formation, reduces drill pipe sub simultaneously telescopic is worn and torn, and reduces frictional resistance.
Diamond composite material anti-wear material for drill pipe joint among the present invention, comprise that matrix and the polycrystalline diamond made by cast tungsten carbide, copper, cobalt, nickelalloy form, wherein polycrystalline diamond is with the synthetic diamond single crystal's micro mist between the about 1～100um of diameter, adds the matrix metal of certain proportioning or the oarse-grained polycrystalline diamond stone material that other materials is polymerized under High Temperature High Pressure.Described matrix is made by the cast tungsten carbide of 50-70% (weight) and copper, cobalt, the nickelalloy of 30-50% (weight), and matrix and polycrystalline diamond are with the mode combination of metallurgy.
That the shape of described polycrystalline diamond has is cylindrical, rectangle, cambered surface rectangle etc.
Described matrix is that 20 to 200 purpose cast tungsten carbides and 35% (weight) copper, nickel, cobalt-base alloy are made by 65% (weight), granularity.
Including granularity in the cast tungsten carbide of described 65% (weight) is 20-40 purpose cast tungsten carbide 20-40 part (weight), granularity is 40-80 purpose cast tungsten carbide 10-20 part (weight), and granularity is that 80-120 purpose cast tungsten carbide 10-20 part (weight), granularity are that 120-160 purpose cast tungsten carbide 10-20 part (weight), granularity are 160-200 purpose cast tungsten carbide 10-20 part (weight).
Described copper, cobalt, nickelalloy are made by the cobalt of the copper of 60 parts (weight), 20 parts (weight) and the nickel of 20 parts (weight).
Description of drawings
Fig. 1 is the semisectional view of wear-resistant belt on the drill pipe sub body among the present invention;
Fig. 2 be shown in the sectional view of wear-resistant belt;
Fig. 3 is the shape figure of polycrystalline diamond among the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment in the patent of the present invention is described in further detail.
As shown in Figure 1; on the surface of drill pipe sub body 1; car goes out a circular groove; wear-resistant belt welds together by weld bond 2 and drill pipe sub body; 3 one-tenth arc surfaceds of polycrystalline diamond; exceed drilling rod street corner body a little, drill pipe sub had both been formed effectively effectively protection, reduced again telescopic is worn and torn.
As shown in Figure 2, wear-resistant belt is to be combined in metallurgical mode by 3 uniform steel loops, matrix and polycrystalline diamonds, the steel annulus 4 that links to each other with matrix can form effective combination with matrix and polycrystalline diamond 5, can well weld together by weld bond 6 and drill body again.Adopt the method for welding, neither influence the original hardness of drill pipe sub body, prevent again wear-resistant belt with the friction process on stratum in come off.
As shown in Figure 3, the shape of the polycrystalline diamond in the invention has cylindrical, rectangle, cambered surface rectangle.
