The present invention relates to composite slow-corrosion scale resistor, the corrosion-proofing and antisludging method and oil production method of oil field water.Composite slow-corrosion scale resistor therein, according to the mass fraction, including：3~9 parts of Phos, 4.5~10.5 parts contain nitrogen organic phosphonic acid, 3~10 parts of without phosphorus polymer corrosion inhibiting and descaling agents, 4~10 parts of sulfur-containing polymer dirt dispersion agents and optional zinc salt.Inhibition and scale inhibition processing of the composite slow-corrosion scale resistor especially suitable for the oil field water under severe rugged environment.
Description
Technical field
It is more particularly to a kind of the present invention relates to composite slow-corrosion scale resistor, the corrosion-proofing and antisludging method and oil production method of oil field water
Corrosion-proofing and antisludging method available for the oil field water under high temperature, the composite slow-corrosion scale resistor of oxygen environment, a kind of high temperature, oxygen environment
With a kind of deep-well, the oil production method of ultradeep well.
Background technology
The crude oil that oilfield exploitation goes out is with substantial amounts of recovered water.Oil well produced crude oil and recovered water is sent through gathering line
Water-oil separating is carried out to multi-purpose station, the sewage isolated send to deoxidation station and removes in water after sewage disposal system processing is up to standard
Dissolved oxygen, most complete oil field extracted water through water-injection station water injection well reinjection into reservoir afterwards（Hereinafter referred to as oil field water）Be circulated throughout
Journey.Water universal salinity in oil field is high, usually dissolved with CO2And H2The corrosive gas such as S, generally in faintly acid（PH 5.5~
7.0）, therefore, oil field water has stronger corrosiveness to oil field equipment and gathering line.According to just slightly estimating, corrode and adopted to China
Loss caused by oily industry accounts for the 6% of the industry gross output value, and takes suitable anti-corrosion measure, can retrieve 30%~40% loss.
In a variety of anti-corrosion measures of metal, corrosion inhibiter is most widely used, at present the corrosion inhibiter of field use mainly have imidazoline,
The types such as Mannich base, the quaternary ammonium salt of azacyclo-, alkynol, pyridine, quinoline, thiocarbamide, these corrosion inhibiter mechanisms of action are mostly to inhale
Attached membrane formation mechanism, i.e. corrosion inhibiter form one layer of continuous or discrete adsorbed film in metal surface, prevent the anode of corrosion process
Reaction or cathode reaction or the progress for preventing two electrode reactions at the same time, reduce corrosion rate.
Above-mentioned corrosion inhibiter respectively has its advantage and disadvantage, such as preferable using most common imidazolines corrosion mitigating effect, but in alkaline ring
Facile hydrolysis in border.Though alkynol class has the advantages that corrosion mitigating effect is preferable, its toxicity is big, additive amount is high, expensive and easily wave
Hair.Similarly there are the problem of the big cost of dosage is higher, compatibility is poor for common Mannich bases and quaternary ammonium salt.Above-mentioned corrosion inhibiter
There are it is common the shortcomings that be that temperature tolerance is not strong, at high temperature easily occur thermal cracking, will be thorough particularly in high temperature, oxygen environment
Bottom is oxidized to CO2And corrosion inhibition is lost, therefore, above-mentioned corrosion inhibiter is only applicable to low temperature, oxygen-free environment in oil field, such as collects defeated
The anti-corrosion of the not high posthole underground equipment of system, sewage disposal system, flood pattern and temperature etc..
Downhole temperature and pressure increase and increase with well depth, in recent years, with deep-well（4500 meters~6000 meters）, ultradeep well
（6000 meters~9000 meters）A large amount of exploitations, the temperature tolerance requirement to corrosion inhibiter is also just higher and higher.In order to improve oil recovering
Rate, the oily later stage passing oil well gas injecting mining crude oil of normal open, the positive effect of gas injecting mining are replaced in water filling, but may be brought serious
Downhole corrosion problem.A major reason for causing the problem is to contain certain density oxygen in gas injection, although being replaced with nitrogen
The oxygen content in gas injection has been greatly reduced in air, but restricted nitrogen technical merit is limited（Film nitrogen）, nitrogen gas purity is only capable of reaching
95.0%~97.5%, wherein can also still cause serious oxygen corrosion containing 2.5%~5.0% oxygen.So far, this area
Also it is difficult to solve the problems, such as this, reason is：On the one hand, anti-corrosion material is replaced, using high pure nitrogen or the cost using deoxidier
It is too high；On the other hand, existing corrosion inhibiting and descaling agent is not suitable for this harsh high temperature, oxygen environment, in reasonable volume model
In enclosing, the corrosion inhibition rate generally only 20%~30% of these corrosion inhibiting and descaling agents.
CN 103030216A disclose a kind of high temperature resistant scaling inhibitor with emulsification and preparation method thereof.Press
Weight fraction meter, calgon 2%~9%, zinc sulfate 13%~20%, polyoxyethylene nonylphenol ether -15 1%~3%, aminotrimethylenephosphonic acid
10%~18%, 2- phosphonic acids -1,2,4- butane tricarboxylates 8%~16% and sodium sulfite 4%~6%.The agent is under 85 DEG C, hypoxia condition
Effect is preferable.
CN102911651A discloses a kind of oil field composite corrosion inhibitor.The mass percent of each component is：Sodium molybdate
5%~10%, sodium phosphate 10%~20%, AA-AMPS copolymers 0.5%~1%, aminotrimethylenephosphonic acid 1%~2%, hydroxy ethylene
Di 2 ethylhexyl phosphonic acid 1%~2%.Corrosion inhibiter effect under 70 DEG C, hypoxia condition is preferable.
CN104233310A discloses a kind of compound Imidazoline Quatemary-ammonium-salt Corrosion Inhibitor and preparation method thereof, the matter of each component
Measuring percentage is：Alkyl acid imidazoline quaternary ammonium salt 30%~35%, nitrogenous organic multicomponent phosphate 8%~10%, amophoteric surface active
Agent 1%~2%, dispersant 0.5%~1%, cosolvent 1%~2%.Corrosion inhibiter effect under 50 DEG C, hypoxia condition is preferable.
So far, in aqueous medium corrosion-resistant field, it there are no high temperature resistant（100 DEG C of ＞）Corrosion inhibiter, more there are no it is both resistance to
High temperature and the corrosion inhibiter of resistance to oxidation.
