Description
Technical field
The invention belongs to oilfield technology field, relate to the chemical reagent added in oil-field water, especially a kind of oil field special corrosion and scale inhibitor.
Background technology
The inhibition of oil-field water, scale inhibition and sterilization have himself feature, and the corrosion in oil field and sulfatereducting bacteria are nearly all associations.We know, zinc salt is good inhibiter, and quaternary ammonium salt is good sterilant.Quaternary ammonium salt and the composite of zinc salt can play good corrosion mitigating effect in oil-field water, and this is because the depolarizer of oil-field water is caused by sulfide and carbonic acid gas.But, because the compatibleness of zinc salt and quaternary ammonium salt is bad, be all immiscible in water, so their synergistic effect does not just use, and cannot carry out practical application always.
By retrieval, find following two sections of patent documents:
1, a kind of disinfecting Scale inhibitors (CN104003528A), comprise following component: calculate with composition quality 100%, the bi-quaternary ammonium salt 1 ~ 30% of quinoline and alkyl tertiary amine, the bi-quaternary ammonium salt 1 ~ 30% of alkyl tertiary amine, organic carbamide compounds 1 ~ 15%, organic amine compound 1 ~ 10%, alkyl quaternary ammonium salts 1 ~ 20%, glutaraldehyde 1 ~ 10%, alkynol class 1 ~ 10%, high fatty acid amide analog derivative 1 ~ 10%, alkylphenol-polyethenoxy polyethenoxy ether 1 ~ 10%, all the other are water.
2, both sexes sterilizing scale inhibiting agent (CN1418830), is made up of alkyl quaternary amine inner salt, quaternary ammonium halide, nonionogenic tenside, solvent and water.This invention belongs to both sexes disinfecting corrosion inhibitor, compared with conventional sterilization algicide, be applicable to industrial circulating cooling water and oil-field flooding, there is good killing effect to heterotrophic bacteria in water (TGB) and sulphate reducing bacteria (SRB), to bacterium algae and biological clay, there is splendid stripping cleanup action and have corrosion inhibition concurrently.
By contrast, above-mentioned patent document and the present patent application are not identical.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of oil field special corrosion and scale inhibitor is provided, this disinfecting corrosion inhibitor makes together with the immiscible compound of quaternary ammonium salt and zinc salt two kinds is compounded into by auxiliary agent, and creates synergistic effect, obtains good scale inhibition effect.
The object of the invention is to be achieved through the following technical solutions:
A kind of oil field special corrosion and scale inhibitor, its raw material is formed and weight percentage ranges is respectively:
The weight percent composition sum of described zinc salt, quaternary ammonium salt, organic phospho acid, polyacrylic acid dispersant and auxiliary agent is between 80%-95%, and all the other add water to 100%.
And described zinc salt comprises Zinc Sulphate Heptahydrate and zinc chloride.
And described quaternary ammonium salt comprises the bi-quaternary ammonium salt of 12-14 carbon, dodecyl benzyl dimethyl ammonium chloride or polyquaternium.
And described auxiliary agent is ethanol or Virahol.
And described organic phospho acid is 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid,
And described polyacrylic acid dispersant is acrylic copolymer.
Advantage of the present invention and positively effect are:
1, the present invention with by zinc salt, quaternary ammonium salt, organic phospho acid, polyacrylic acid dispersant for host, adding by auxiliary agent, cationic quaternary and anionic polyacrylic acid dispersant can be mixed by a certain percentage, solve the two not miscible problem, zinc salt and quaternary ammonium salt is made to dissolve each other and not produce salting out, reduce the zero pour of product, add the mobility of product, solve the mutual solubility problem of zinc salt and quaternary ammonium salt; Detect by experiment, this formula compatibility is good, product is stablized, good corrosion-suppressing effect is had to the carbon steel in the oil-field water being main corrosion composition with sulfide and carbonic acid gas, also good restraining effect is served to the structure trend of oilfield produced water system simultaneously, comprise carbonate scale and common strontium barium dirt, compare with conventional imidazoline corrosion inhibitor, cost is very low.
2, the organic phosphonate that adds of the present invention, its object one allows medicament have scale-inhibiting properties, and two is utilize the synergistic effect of organic phosphonate and zinc salt to improve its corrosion inhibition.
3, the present invention passes through the composite auxiliary agent of science, quaternary ammonium salt and zinc salt are set up synergistic effect, the medicament (great majority adopt polyacrylic acid dispersant) solving resistance strontium barium dirt can not the problem that mixes of the inhibiter tetrahydroglyoxaline general with oil-field water, reduces total consumption of medicament; Dosing process is simple and easy, change oil field for many years single use imidazolidine derivatives as the phenomenon of inhibiter, obtain the accreditation in oil field, a class that the corrosion inhibiting and descaling agent having made oil field is many again, be adapted to the system exceeded standard with the corrosion inhibiting and descaling agent, particularly sulphate reducing bacteria of sulfide and the carbonic acid gas water that is depolarizer.
Embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of oil field special corrosion and scale inhibitor, its raw material is formed and weight percentage ranges is respectively:
All the other add water to 100%.
In the present embodiment, described zinc salt comprises Zinc Sulphate Heptahydrate and zinc chloride;
In the present embodiment, described quaternary ammonium salt comprises the bi-quaternary ammonium salt of 12-14 carbon, dodecyl benzyl dimethyl ammonium chloride or polyquaternium.
Described organic phospho acid is 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid;
Described polyacrylic acid dispersant is acrylic copolymer;
In the present embodiment, described auxiliary agent is ethanol or Virahol.
Application example 1:
A kind of oil field special corrosion and scale inhibitor, its raw material is formed and weight percent is respectively:
Oil Field test-results:
Erosion rate 0.075mm/, vitriol number has no growth, and scale inhibition performance is up to standard.
Application example 2:
A kind of oil field special sterilizing inhibiter, its raw material is formed and weight percent is respectively:
Oil Field test-results:
Erosion rate 0.075/ year, sulphate reducing bacteria number has no growth, and scale inhibition performance is up to standard.
Working mechanism of the present invention is:
Two kinds of main components of the present invention have scale effect, are all negative electrode Scale inhibitorss.Zinc salt can film forming well in smooth metallic surface, but does not have perviousness; Quaternary ammonium salt exactly has good perviousness, also has certain corrosion inhibition simultaneously; Especially be that the quaternary ammonium salt bactericide of representative belongs to cationic germicide with dodecyl benzyl dimethyl ammonium chloride, and all salts have salting out to generate precipitation, the salt particularly more than divalence, such as zinc salt.The object adding organic phospho acid, polyacrylic acid dispersant and ethanol or Virahol can make zinc salt and quaternary ammonium salt dissolve each other exactly, does not produce salting out; The object adding ethanol or Virahol has two, and one is the mutual solubility increasing above-mentioned chemical, and one is the zero pour reducing product, increases mobility.
