Description
Technical field
The present invention relates to a kind of production technology of wear-and corrosion-resistant internal coating tubing, belong to pit shaft Prevention Technique field, oil field.
Background technology
Wear problem between sucker rod and oil pipe is to affect the normal one of the main reasons of producing in oil field always.Tubing internal coating guard technology applies a kind of coating at tube inner wall exactly, it is reached and slow down wearing and tearing, extends the oil pipe method in service life.In prior art, mainly can be divided three classes: traditional undercoating, modified undercoating, monoblock type overcoat.Illustrate as follows:
CN87100920A discloses the painting method of a kind of anti-corrosion wear resisting powder paint and this coating, and the percentage by weight of the each component of this coating is: epoxy E12 is 100, and glass-cermic powder is 20-200, and dicyandiamide is 3-5, and nylon powder is 10-30, and polyvinyl butyral resin is 5-8; Its painting method is: the sandblast of deoiling, and heated parts, podwer gun applies, and is incubated cooling.The docking tensile strength of this coating is 60MPa, and erosion corrosion test wear extent is cast iron 1/4.
CN1283660A discloses a kind of high-strength anticorrosion antiwear powder paint and painting method thereof, and the weight ratio of the each component of coating is: epoxy E10 is 100, and glass-cermic powder is 80-120, and dicyandiamide is 1.8-2.8, and sebacic dihydrazide is 0.3-0.8, and polyethylene powder is 10-30; Its painting method and CN87100920A are basic identical, and chilling temperature and hardening time reduce to some extent, tensile strength 90-95MPa.
CN101735572A discloses a kind of formula and production technology of eccentric wear-resistant oil pipe, and raw materials comprises glass fiber yarn, epoxy resin, curing agent, flexibilizer and levelling agent, and wherein the weight ratio of bisphenol A-type resin and acid anhydrides is 100:80-100; Its production technology comprises winding, solidifies, the demoulding and four techniques of moulding, and product is a whole glass steel pipe.
By relatively finding out, mainly there is the defects such as cost is higher, and hardening time is long, and intensity is low in traditional undercoating.Modified undercoating adopts polyethylene powder to replace nylon powder, greatly reduces cost; Adopt dicyandiamide and sebacic dihydrazide mixed curing agent, significantly shortened hardening time, tensile strength also increases; But the shortcoming of the method is that high-temperature heat-resistance performance is poor, the thicker pipe aperture that changed of coating, coefficient of friction is high.Monoblock type overcoat intensity is high, and Wear-resistant corrosion-resistant performance is excellent, and resistance to elevated temperatures is good, and media flow performance is good; But exist production cost high, bent toughness is poor, easily aging, the shortcoming such as sealing joint is poor.
Summary of the invention
The object of the invention is to develop a kind of production technology of wear-and corrosion-resistant internal coating tubing, makes it have cost low, and coefficient of friction is little, wear-resistant anti-corrosion, does not change pipe aperture size, and resistance to elevated temperatures is good, can suppress the feature such as tube wall incrustation, wax deposition.
Concrete technical scheme of the present invention is as follows:
Formulation for coating material by weight as follows:

2) be important kollag, be described as " senior solid oil king ", coefficient of friction is only 0.05-0.09, has the characteristics such as waterproof, alkali prevention, acid-proof, Mohs' hardness 1.0-1.5, density 1.8g/cm
3, fusing point is 1185 DEG C.Therefore in electrostatic painting process, do not melt, but be uniformly distributed and be embedded in coating, increase coating hardness, significantly reduce coefficient of friction.Molybdenum bisuphide has the immovable feature of lubricant effect under HTHP, and in the time of oil pipe and rod drag intensification, self-lubricating effect is still fine.
Mix greatly to shorten the hardening time of epoxy resin with dicyandiamide and sebacic dihydrazide; In formula, increase the ratio of sebacic dihydrazide, solidified the temperature required and time to reduce, increased the bond strength of coating.
Eight steps such as production technology of the present invention comprises the sandblast of deoiling, batch mixing, preheating, electrostatic spraying, solidifies, moulding, sanding and polishing, inspection and Powder Recovery, are specially:
(1) sandblast of deoiling: oil pipe is deoiled, inwall sandblast, rust cleaning.
(2) batch mixing: coating is mixed by formula rate, pack in storage tank after ball mill grinding, be connected with spray gun by feed hose, spray gun connects negative pole.

(5) solidify: reduce tubing spinning speed to 20-30r/min, temperature is controlled at 160-170 DEG C, solidifies 20-30min.
(6) moulding: by conveyer, the oil pipe being cured is moved to post processing zone, cooling forming.
(7) sanding and polishing: clamp-on internal coating tubing with 1500# or 2000# elastic sand ball, under the effect of control lever, equidirectional, fast by oil pipe 3-5 time, is removed the not molten powder of coating surface, reduces surface roughness, makes it smooth.
(8) inspection and Powder Recovery: internal coating tubing is warehousing after passing after testing; Residual powder is absorbed in recycling can, after vibratory sieve filters, packs in proportion storage tank together with virgin material into.
Electrostatic Spray Technology is to utilize high-pressure electrostatic electric field to make electronegative paint particles along the directed movement of electric field rightabout, and paint particles is adsorbed on to a kind of spraying method of surface of the work.Principle is: when work, between spray gun and workpiece, form a high-voltage corona discharge electric field, in the time that coating powder sprays through region of discharge by spray gun, the a large amount of electronics of Portable belt, become electronegative particulate, under the effect of electrostatic attraction, high-speed motion is to positively charged tube inner wall, because oil pipe temperature is now 180-200 DEG C, the processes such as coating powder can be through fusing, absorption, solidify, moulding, finally form even, fine and close wear-and corrosion-resistant undercoating at tube inner wall.
Beneficial effect of the present invention:
(1), because coating powder is adsorbed in tube inner wall under electric field acceleration, the adhesion of coating and tensile strength are significantly improved.
(2) in formulation for coating material, added the kollag such as molybdenum bisuphide and graphite, made coating have good self-lubricating function, coefficient of friction significantly reduces.
(3) coating layer thickness is 300-500 micron, and tubing string effective drift diameter is unchanged, and underground construction instrument is without special; Resistance to elevated temperatures is good, can be less than at 150 DEG C and use in well temperature.
(4) after undercoating sanding and polishing, smooth surface is smooth, and air flowability is good, can suppress in-tube fouling, wax deposition.
(5) energy-saving production technology environmental protection, hardening time is short, and cost is low, and wear-and corrosion-resistant performance is good, can significant prolongation tubing life.
