Abstract
The invention discloses a novel sucker rod centering guide and a preparation method thereof, belonging to the anticorrosive wear-resisting technology for oil pipes and solving problems in other technologies at present. The novel sucker rod centering guide is based on the principle that a surface dry film of the high polymer material is relatively smooth, can resist a high temperature, hardly cause an adhesion problem and has a very low friction coefficient under the condition that the surface finish is the same. The preparation method of the novel sucker rod centering guide comprises the following steps: mixing and grinding various materials by virtue of a high-energy ball milling method, carrying out thermoforming, and tightly combining with a sucker rod into a whole.
Description
Technical field: the present invention relates to oil pipe anti-corrosive wear-proof technique, especially a kind of novel oil pumping rod centering device and preparation method.
Background technology: at present, in each elephant of China, have bar producing well number to account for more than 85% of recovery well well number.Along with deepening continuously of oil-field development, long horizontal traverse well and orientation well increase gradually, the composite water cut of old well rises year by year, the situations such as the eccentric wear of oil well, corrosion are caused constantly to be aggravated, frequently there is the problems such as disconnected de-, eccentric wear, leakage, corrosion failure, not only have impact on normal production, and add workover cost and cost of development, bring tremendous economic loss to oil field.Because eccentric wear, corrosion cause the number of times of pump detection and workover to account for 65 ~ 85% of total well in operation number of times.
In recent years, people conduct in-depth research for the eccentric wear conjunction etching problem of oil well, propose much new technology and means.For sucker rod, propose the measures such as centralizer, righting rod, multifunctional polished rod eye, but regulation effect is not obvious, fails effectively to extend pump detection period.
Summary of the invention: the object of this invention is to provide a kind of novel oil pumping rod centering device and preparation method with corrosion and wear function, it solve other technology Problems existing at present, the object of the present invention is achieved like this, it utilizes macromolecular material under surface smoothness same case, because surperficial dry film is comparatively smooth, and high temperature resistant, not easily there is adherent phenomenon, the principle that frictional coefficient is very low.
It has following raw material to make:
A epoxy resin E12 5-35%
B high-molecular polythene 62-82%
C graphite 1-3%

F sebacic dihydrazide 0.5%.
Its preparation method is: by high-energy ball milling method after above multiple material mixed grinding, thermoplastic shaping, is closely integrated into sucker rod and is integrated.
Nonmetal composite anti-wear coating major ingredient is silicon carbide, composite nylon, E type epoxy resin and polymer raw material; Its preparation method is: carry out mechanical mill by high-energy ball milling method to above powder mix and finally formed, and has the composite particles of the nano level subgrain powder being different from raw material powder, the composite powder that single nanoparticle and amorphous coexist.
Meaning of the present invention is: the present invention has anticorrosion, abrasionproof effect, has graphite and MOS in centralizer
2the solids such as micro mist, there is self-lubricating property, there is again hardness simultaneously raised to wear-resistant, preservative activity, therefore self-lubricating polymer centralizer particular tube column combination uses, and has anti-attrition and closes wear-resistant dual function, significantly can reduce the friction between oil pipe and sucker rod, improve oil pipe work-ing life, extend pump detection period.
The mechanism of action of nonmetal composite anti-wear coating is: (1) utilizes the hardness of silicon carbide to improve wear resistance and the antiseptic power of coating; (2) adopt ultra-fine, low water absorption multiple elements design nylon powder to improve impact resistance and the wear resisting property of coating; (3) application E type epoxy resin and extraordinary solid lubricant improve the smooth finish of coatingsurface, reduce coating frictional coefficient.(4) diversification polymkeric substance is used to carry out the bond strength of guard ring epoxy resins solidification intensity and coating and tube inner wall.
