Background technique
Oil field production enters the middle and later periods, and well water constantly increases, middle high-salinity brine, sour gas CO2/H2S and thin
The presence of bacteria microorganism, drastically influence that oil well collection is defeated and sewage disposal system in metal pipe material extent of corrosion, wherein bacterium
The presence of microorganism, especially anaerobe SRB, are easily adsorbed on tube wall, and metal pipe material local corrosion is caused to perforate.
At present oil field for middle high-salinity brine, sour gas corrosion using single type of medication as corrosion inhibiter,
Itself does not have bactericidal and bacteriostatic effect；The existing quaternary ammonium salt type fungicide that directed toward bacteria microbiologic(al) corrosion uses, although tool
There is certain anti-corrosion effect, but because the adsorbed film that it is formed in metal surface is not fine and close, be easy to cause local corrosion.Therefore in oil
Oil well collection in the production of field is defeated and sewage disposal system needs one kind not only has anti-corrosion effect, but also the antibacterial type with bactericidal effect
Corrosion inhibiter solves live etching problem.
Summary of the invention
It is a kind of for oil well collection to be defeated and sewage treatment system it is an object of the invention to be provided for above-mentioned defect
Antibacterial type corrosion inhibiter of system and preparation method thereof, the antibacterial type corrosion inhibiter is both to CO2/H2S acid medium and Cl-The corrosion of initiation
There is good sterilization and fungistatic effect with good inhibiting effect, and to bacteriums such as SRB, TGB, FB common in oil field,
And this product is nontoxic, easy to oil reservoir fanout free region, constructing operation, overcomes single type of medication and adds heavy workload, field conduct
The disadvantages of management is difficult, dosing is at high cost and is incompatible.
The technical solution of the present invention is as follows: it is a kind of for oil well collection to be defeated and the antibacterial type corrosion inhibiter of sewage disposal system, including
Following raw material: sterilization inhibition host agent, synergist, auxiliary agent and water；Wherein sterilization inhibition host agent is hydroxyl quaternary ammonium salt, the hydroxyl
The general structure of quaternary ammonium salt are as follows:
Wherein R is phenyl or-COONa.
It is described for oil well collection to be defeated and the antibacterial type corrosion inhibiter of sewage disposal system, prepared by the raw material of following weight ratio and
At: sterilization inhibition host agent is 40~50%, and synergist is 5~10%, and auxiliary agent is 8~10%, and water is 30%~45%.
The synergist is the mixture of sodium gluconate and thiocarbamide, wherein by weight sodium gluconate: thiocarbamide 1:1
~2.
The auxiliary agent is the mixture of dodecyl benzyl dimethyl ammonium chloride and Kathon CG, wherein by weight dodecyl
Dimethyl benzyl ammonium chloride: Kathon CG is 1~3:1.
The concentration that adds of the antibacterial type corrosion inhibiter is 30~100ppm.
Preparing for the sterilization inhibition host agent is specific as follows: the ratio first by pyridine and formaldehyde according to molar ratio 1:1~3
It is added into the reactor equipped with condensation reflux unit, 4~6h is reacted under the conditions of 90 DEG C；Then quaternary ammonium reagent is added dropwise
RCH2Cl, wherein according to molar ratio pyridine: RCH2Cl is 1:0.6~0.9, and 90 DEG C of 4~6h of reaction of temperature control are up to sterilization inhibition master
Agent；R is phenyl ,-COONa.
Reaction process is as follows:
The pyridine and formaldehyde are 1:3 according to molar ratio；According to molar ratio pyridine: RCH2Cl is 1:0.9；First in 90 DEG C of items
4h is reacted under part；Quaternary ammonium reagent RCH is being added dropwise290 DEG C of reaction 6h of temperature control after Cl.
It is described for oil well collection to be defeated and the preparation method of sewage disposal system antibacterial type corrosion inhibiter, comprising the following steps:
Pyridine and formaldehyde are added according to the ratio of molar ratio 1:1~3 to the reactor for being furnished with condensation reflux unit first
In, 4~6h is reacted under the conditions of 90 DEG C；Then quaternary ammonium reagent RCH is added dropwise2Cl, wherein according to molar ratio pyridine: RCH2Cl is
1:0.6~0.9,90 DEG C of 4~6h of reaction of temperature control are up to sterilization inhibition host agent；
Then adding water 30%~45% in another reactor, synergist 5~10%, stirring makes it completely dissolved, then plus
Enter 8%~10% auxiliary agent, 40%~50% sterilization inhibition host agent stirs 30min, antibacterial type corrosion inhibiter can be obtained.
The invention has the benefit that of the present invention for oil well collection to be defeated and the antibacterial type corrosion inhibiter of sewage disposal system
Pyridine, formaldehyde and quaternary ammonium reagent RCH are used first2Cl synthesizes sterilization inhibition host agent, and then compound synergic agent and auxiliary agent mention
Height sterilization corrosion mitigating effect.
Wherein sterilization inhibition host agent is hydroxyl quaternary ammonium salt, contains reactive hydrogen atom in molecule, can be with-NCO in bacterium
Reaction makes antimicrobial molecule become a part in macromolecular, to make in macromolecular because having antibacterial effect containing antibacterial group；
In addition the host agent passes through the quaternary ammonium reagent RCH2Cl's is quaternary ammoniated, has stronger release effect, can kill and be grown in
SRB below clay；Because containing the electrophilic groups such as-OH in molecule, there is preferable film forming, corrosion inhibition in metal surface
It is superior；The molecule is quaternary ammonium salt, itself is positively charged, can receive the negative electrical charge that anode ionization generates, inhibits cathode to generate, hinder
Only corrosion carries out, and plays the role of inhibiting corrosion.
There is synergistic effect, synergist is the mixing of sodium gluconate and thiocarbamide between synergist and sterilization inhibition host agent
Object contains 6-OH first in sodium gluconate, can form hydrogen bond between sterilization inhibition host agent, a large amount of hydrogen bond can make gold
The adsorption layer of metal surface thickeies, and forms retardance H+Close to the barrier of metal surface, the generation of corrosion is reduced；Secondly sterilization inhibition
Host agent and sodium gluconate are all rigid annular structures, are deposited when absorption film-forming since architectural characteristic has been easy gap in metal surface
At this moment the thiocarbamide of small molecule structure is being needed to be filled up, the compactness of Lai Zengqiang adsorbed film improves corrosion mitigating effect.
Also there is synergistic effect between auxiliary agent and sterilization inhibition host agent, sterilization inhibition host agent cannot be completely dispersed in water,
The cationic surfactant dodecyl benzyl dimethyl ammonium chloride for needing to have bactericidal effect is dispersed, and divides it uniformly
It dissipates and improves corrosion inhibition sterilizing effect in water, while the addition of Kathon CG enhances bactericidal effect.
The antibacterial type corrosion inhibiter has the advantage that
(1) overcoming that single type of medication adds heavy workload, field conduct management is difficult, dosing is at high cost, is incompatible etc. lacks
Point.
(2) the antibacterial type corrosion inhibiter is both to CO2/H2S acid medium and Cl-The corrosion of initiation has good inhibiting effect, again
The bacteriums such as SRB, TGB, FB common to oil field have good sterilization and fungistatic effect,
(3) this product is nontoxic, easy to oil reservoir fanout free region, constructing operation, reduces medicine machine investment and field management
Difficulty.
(4) inhibition bactericidal property is improved by compounding.
(5) disinfecting corrosion inhibitor host agent synthesis technology is simple, high-efficient.
