Abstract
The utility model relates to an underground oil tube in the oil field, in particular to a highly wearproof composite oil tube. The technical scheme is as follows: the highly wearproof composite oil tube comprises an oil tube; an inorganic wearproof and corrosion-resisting layer is arranged at the inner wall of the oil tube and is a glass body with a smooth surface; and the glass body is formed through fusion under high temperature. The highly wearproof composite oil tube has the beneficial effects that (1), the wearproof and corrosion-resisting layer is made of an inorganic material, so as to have longer service life than any other organic coating; (2), the corrosion resistance is good, and the flowability is good: a glass matter is formed on the inner surface of the oil tube, the inner wall is smooth and has high hardness, so that the corrosion resistance and the medium flowability are strong; and (3), the property of temperature difference resistance is good, so that the surface of the oil tube does not change in long-term use under 50-200 DEG C.
Description
One, technical field:
The utility model relates to a kind of oil field down-hole oil tube, particularly a kind of high abrasion composite oil pipe.
Two, background technology:
Because the planning in urban construction and various places causes the oil field to adopt the quantity of inclined shaft more and more in well-digging, its proportional numbers accounts for about 30%, therefore reveals the drawback of coming and also shows.It is to be again comparatively serious problem comparatively generally in the oil well production that sucker rod pumping well eccentric wear causes pipe, bar wearing and tearing.Carry out the research and the application of multiple process matched therewiths such as wear-resistant corruption, anticorrosive bar, pipe in recent years, but still existed problems such as the input expense is high, pump detection period is short.Wherein the eccentric wear problem of down-hole oil tube causes the oil pipe mill thoroughly and stops well, crude output is reduced to the oil field cause very big loss.The eccentric wear problem that solves down-hole oil tube has become a kind of important topic in oil field.(2) in oil field oil recovery block, indivedual oil reservoir sand contents are high.Oil is husky comparatively serious to the wearing and tearing of down-hole oil tube inwall, and reduced the application life of oil pipe, has caused the cost for oil production increase.
At present, solve the eccentric wear of oil field down-hole oil tube, mainly adopt the various organic anti-wear materials of liner like oil pipe liner nylon, oil pipe inner lining glass fiber reinforced plastic, oil pipe spraying abrasion-proof coating and oil pipe nitrogen treatment.But, because organic material receives the influence of environment temperature bigger, occurring problems such as wearing out, go bad, come off easily, and cause the secondary pollution of crude oil, this inadequate natural endowment of organic material can't fundamentally solve the problem of existence.
Three, summary of the invention:
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of high abrasion composite oil pipe is provided, and is main with inorganic material, and high temperature forms the high abrasion composite bed, so resistance to corrosion is strong, hardness is high, smooth surface, friction factor are little; Thereby anti-eccentric wear performance is improved greatly.
Its technical scheme is: comprise oil pipe, the inwall of described oil pipe is provided with inorganic wear resistant corrosion resistant layer, and described inorganic wear resistant corrosion resistant layer is the ganoid vitreum that under the high-temperature fusion situation, forms.
The beneficial effect of the utility model is: (1) is the wear resistant corrosion resistant layer that inorganic material is processed because of what adopt, and the life-span of use is all longer than any organic coating.(2) abrasion resistance, good fluidity: because of form a kind of Vitrea material at pipe inner surface, its inner wall smooth, hardness height are so have very strong abrasion resistance and air flowability.(3) temperature difference resistance can be fortunately-50 °-200 ° long-term use surperficial no changes.
Four, description of drawings:
Accompanying drawing 1 is the structural representation of the utility model.
Five, the specific embodiment:
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model comprises oil pipe 1, and the inwall of described oil pipe 1 is provided with inorganic wear resistant corrosion resistant layer 2, and described inorganic wear resistant corrosion resistant layer 2 is the ganoid vitreums that under the high-temperature fusion situation, form,
This inorganic wear resistant corrosion resistant layer 2 is to be main with silicate material, and high temperature forms Vitrea inorganic matter, so resistance to corrosion is strong, hardness is high, smooth surface, friction factor are little; Thereby anti-eccentric wear performance is improved greatly.
The material hardness that the wearing layer of the utility model is selected for use reaches Morse 1336Mpa and reaches the hardness near glass, adopts the ASTMD-968-1981 standard to carry out the wear-resisting experiment of knockout, and test result is 5.8L/um, so have good abrasion resistance; Wearing layer is the vitreum that under the high-temperature fusion situation, forms, surface-brightening, level and smooth, and the friction factor between any material is all very little; Wearing layer has-50 ° of-200 ° of high-temperature resistant difference performances, applicable to one or two km down-hole geological condition complicated and changeable.This new technique has the other materials incomparable advantage with self high performance characteristics, fundamentally improves oil pipe anti-wear performance and antiseptic power.
