Technical field
The present invention relates to a kind of high-performance anticorrosion Special packer processing technologys.
Background technique
Packer is the important tool of the oil-separating layer in casing, its main element is packing element, passes through waterpower or machinery
Effect, seal rubber tube bulging, tubing and casing annular space separates oil reservoir up and down, in recent years, with oil-gas exploration to it is complicated in length and breadth
Briquetting development, drilling well, well-completing process also constantly develop to deeper more complicated stratum, these bad grounds often contain acid, oil-containing, contain
Alkali, sulfur-bearing, part well H2S content is higher, and just to packer research and development, more stringent requirements are proposed for this, and there is an urgent need to can be in market
High temperature contains acid, contains alkali, sulfur-bearing, contains H2The high-performance anticorrosion Special packer that the complex hole conditions such as S use.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of can contain sour sulfur-bearing containing alkali in high temperature and contain H2The Holes of Complicated Wells such as S
The high-performance anticorrosion Special packer processing technology that condition uses.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that: a kind of dedicated packing of high-performance anticorrosion
Device processing technology, comprises the technical steps that:
(1), packing element is made: production packing element: according to quality very than by the EP rubbers of 25-35%, 8-
The carbon fiber of 10% fluorine rubber 26B, the polyether-ether-ketone of 20-25%, 10-15% uniformly mixes, and adds the diphenylguanidine vulcanization of 3-5%
The O-phthalic of agent, the magnesia activator of 2-3%, the anti-aging agent RD of 4-5%, carbon black the reinforcing agent C311,3-5% of 5-8% is aching and limp
Agent, the 4- methyl-6-tert-butylphenol antioxidant of 3-5%, 2-3%N- nitrosoaniline antiscorching agent, which be kneaded, is made packer
Packing element；
(2), Anticorrosion measure processing is carried out to packer top connection, central tube, lower contact, rubber tube seat and compression inner sleeve: according to
Quality is very than by the titanium nitride of 55%-65% partial size 1um, the tungsten carbide powder of 30%-40%, the aromatic ring hydramine rouge of 4-6% press than
Example mixing, carries out scorification with supersonic velocity flame plating equipment, by spraying powder scorification to melting state, reaches 1250 DEG C in temperature
When, spray pattern is just presented in mixing blasting medium, and atomization particle is ejected into packer top connection, center with the speed of 650m/s
Pipe, lower contact, rubber tube seat and compression inner sleeve surfaces externally and internally, coating layer thickness are controlled in 0.4-0.5mm, porosity < 1.12%；
(3), will through the packer top connection of preservative treatment in step (2), central tube, lower contact, rubber tube seat, compress inner sleeve with
Packing element in step (1) is assembled into high-performance anticorrosion Special packer.
The invention has the advantages that a kind of high-performance anticorrosion Special packer processing technology of the present invention, improves rubber compounding:
Packing element is the core component of packer, and conventional packing element is made of rubber material, and rubber is nonlinear elastic material, by
Deflection is big after load effect, meets corrosive substance and easily chemically reacts, reduces performance.Packing element is set to have acid-fast alkali-proof resistance to
H 2The complex hole conditions medium such as S, it is necessary to change rubber material ingredient, promote packing element comprehensive performance.The third colloid of second is that a kind of saturation is high
Polymers, ageing-resistant, corrosion resistance is preferable, shock resistance elasticity is strong, and fluorine rubber 26B is the macromolecule of main chain and side chain containing fluorine atom
Elastomer has superelevation chemical stability, superpower resistance to oleic acid and H2S, corrosion resistance and high temperature resistance.Polyether-ether-ketone is main
The high polymer of chain two ehter bonds Han a ketonic bond has resistant to chemical etching and high temperature resistance, and Wear and Sliding Wear Properties of Organic is excellent, carbon
Fiber is a kind of fibrous carbon material, and intensity is bigger than steel, and density ratio aluminium is small, corrosion-resistant stronger than stainless steel, axial strength and modulus
It is higher.Synthesis mentions fusing point up to 376 DEG C, 192 DEG C of softening point after four kinds of ingredients are kneaded polymerization, and tensile strength 34-41MPa is pulled apart
Elongation 420-490%, tearing strength 35-41Kg/m, peel strength reach 35-42KN/m, press after 200 DEG C × hot air aging for 24 hours
Change≤20%, 70 DEG C × 48h, H2SO4Liquor capacity change rate≤3.Through repetition test, which manufactures packing element can be in high temperature
180 DEG C contain H containing sour sulfur-bearing containing alkali2It is used safely in the complex dielectrics well such as S.Scorification is carried out with supersonic velocity flame plating equipment, it will
Powder scorification is sprayed to melting state, when temperature reaches 1250 DEG C, spray pattern is just presented in mixing blasting medium, will be atomized grain
Son is ejected into lower contact on packer with the speed of 650m/s, central tube, rubber tube seat, compresses appearance in the metal parts such as inner sleeve
Face, to obtain bond strength height, compactness is good, the high coating of corrosion resistant performance.Coating layer thickness is controlled in 0.4-0.5mm, hole
Degree < 1.12% reduces the use cost of alloy since the large scale of titanium nitride uses, at the same metal parts oil resistant, it is acidproof,
Resistance to H2S performance is significantly increased, to ensure in height containing sour sulfur-bearing and H2It is used safely for a long time in S oil/gas well.
