Abstract
The present invention relates to a kind of preparation method of new type bactericide, the new type bactericide is made up of the component of following parts by weight：20 40 parts of 20~30 parts of epoxychloropropane, 20~30 parts of dimethylamine, 20~30 parts of organic amine cross-linking agent, 1~5 part of sodium hydroxide, 10~20 parts of ammonium persulfate and ethanol；Wherein, the organic amine cross-linking agent is the mixture of ethylenediamine and polyacrylamide, and the mass ratio of ethylenediamine and polyacrylamide is 1:1.5~1.9.The advantage of the invention is that：By preparation method of the present invention, the bactericide prepared is complex bactericide, and bactericidal effect is obvious；The addition of potassium permanganate built agent therein so that bactericide plays oxidation disinfection effect, and the new type bactericide bactericidal effect is rapid, and residual acid will not be produced in crude oil, easy to use, and building-up process is easy and cost is low.
Description
Technical field
The present invention relates to a kind of bactericide, more particularly to a kind of preparation method of new type bactericide.
Background technology
With the continuous progress of oil extraction, oil recovery technique is continued to develop and applied.Current each oil field enters
Secondary oil recovery later stage and tertiary oil recovery initial stage, displacement of reservoir oil by filling water and ternary composite driving are widely applied, particularly displacement of reservoir oil by filling water
The implementation of measure so that oil field can all produce substantial amounts of oil extraction-generated waste water daily.Often containing substantial amounts of harmful thin in oil extraction waste water
Bacterium, such as sulfate reducing bacteria, saprophytic bacteria, paste bacterium and other harmful microorganisms, and the existence pH condition of sulfate reducing bacteria
Scope is very wide in range, and almost PH can survive between 5.5~9, and they are in growth, metabolism, reproductive process, bacterium colony in groups
It is attached to metal surface and plays unpolarizing to metal.During oil exploitation, drilling-production equipment, water injection pipe can be caused
The heavy corrosion of line and other metal materials, causes oil pipe to be perforated, and damages oil reservoir, causes water injection rate, oil production rate, oil gas quality
Decline；Secondly, the product of formed solid is peeled off after corrosion and blocks pipeline, also brings exceptional hardship for crude oil processing,
Cause great economic loss.
At present, the quaternary ammonium salt bactericide of cationic is generally used during domestic oil extraction, if this series bactericidal agent
It can be reacted in the polymer-flooding sewage containing anionic polymer with polymer, reduce the viscosity of polymer, and formed
Not soluble in water, the sticking floccule of tool, is blocked and corrosion flood pattern, if can also drop rock permeability into underground
It is low.At the same time, due to long-term and long-term quaternary ammonium salt bactericide is used for multiple times, the harmful bacteria pair in oil extraction waste water can be caused
This series bactericidal agent develops immunity to drugs, thus the bactericidal effect of such bactericide declines, to produce preferable bactericidal effect just
The usage amount of bactericide must be increased, this is all unpractical for the production cost of crude oil and the sterilization of long-term oil field.
The content of the invention
The good new type bactericide of low and bactericidal effect the technical problem to be solved in the present invention is to provide a kind of production cost
Preparation method.
In order to solve the above technical problems, the technical scheme is that：A kind of preparation method of new type bactericide, it is innovated
Point is：The preparation method comprises the following steps：
（1）By 20~30 parts by weight dimethylamine, 20~30 parts by weight organic amine cross-linking agents, 20~40 parts by weight of ethanol and 1~5 weight
Amount part sodium hydroxide is added in reactor, under the conditions of temperature is 40~100 DEG C, stirring reaction 3~7 hours, obtains middle production
Thing；Wherein, the organic amine cross-linking agent is the mixture of ethylenediamine and polyacrylamide, and the matter of ethylenediamine and polyacrylamide
Amount is than being 1:1.5~1.9；
（2）20~30 parts by weight epoxy chloropropanes of dropwise addition into above-mentioned intermediate product, dropwise reaction 1.5 hours, after being added dropwise,
Continue stirring reaction and obtain product quaternary ammonium salt bactericide in 1~4 hour；
（3）10~20 parts by weight ammonium persulfates are added into quaternary ammonium salt bactericide, stirred, that is, disinfecting is made
Agent.
The advantage of the invention is that：By preparation method of the present invention, the bactericide prepared is complex bactericide, is killed
Bacterium positive effect；The addition of potassium permanganate built agent therein so that bactericide plays oxidation disinfection effect, the new type bactericide
Bactericidal effect is rapid, and residual acid will not be produced in crude oil, easy to use, and building-up process is easy and cost is low.
