Abstract
The invention relates to an isothiazolinone water treatment bactericide, which is characterized by being composed of, by weight, 60-75% of deionized water, 5%-12% of benzyl chloride, 2%-4% of a wetting agent, 6%-12% of trimethylamine, 1.5%-4.5% of isothiazolinone, and 4%-8% of chlorine dioxide. The preparation process includes: adding deionized water, benzyl chloride, the wetting agent, trimethylamine, isothiazolinone and chlorine dioxide sequentially into a stirring reactor to conduct stirring for 30min, thus obtaining a liquid product. The isothiazolinone water treatment bactericide provided by the invention has no corrosivity, no irritation and no foam, is an upgrade product of the oilfield SRB bactericide, and the product effect reaches the domestic leading level. In addition, the preparation process has the advantages of simple operation, no emission of pollutants, mild reaction conditions, and low energy consumption, thus meeting the requirements of sustainable development.
Description
Technical field
The invention belongs to water treatment field, be specifically related to oil field reinjection water treatment agent, refer to a kind of isothiazolinone water treatment biocide and preparation method thereof especially.
Background technology
In tertiary oil production in oil field note is poly-, need a large amount of reinjected water, owing to generally all containing the bacteriums such as sulfate reducing bacteria (SRB), saprophytic bacteria (TGB) and iron bacteria, the raised growth of these bacteriums and breeding in reinjected water, not only reservoir is caused damage blocking, affect development effectiveness, cause oil recovery factor to decline, and make water injection well pressure increase, water injecting consumption rises, therefore, bactericide is selected will to start with for these bacteriums.Reinjected water contains higher calcium ions and magnesium ions simultaneously, easily make waterflood-transmission line and stratum serious scale, thus cause waterflood-transmission line and formation blockage, these cause huge economic loss all to oil field production run, therefore, generally all need to add bactericide before produced-water reinjection and carry out pretreatment.
Because the vitality of bacterium is extremely strong, any one bactericide length service time all can make bacterial resistance occurred, causes the problems such as the germicidal efficiency of bactericide declines, dose increase, therefore, needs constantly to develop new oil field bactericide.China has made extensive work in the research and development of oil field bactericide, at present still based on SAA series bactericidal agent.Along with the development of water technology, people have higher requirement to bactericide.
In sum, in order to raise the efficiency, reduce costs, development environment close friend, potion multiple-effect, adapt to bacterial dissociation pesticide resistance, adapt to different quality, inevitable direction that new product that compatibility is good is bactericide development.
Summary of the invention
The object of the present invention is to provide a kind of oil-field flooding bactericide and manufacture method thereof, mainly solve the problem existing for above-mentioned prior art, maximum bacterium is endangered for oil field, as sulfate reducing bacteria, iron bacteria and saprophytic bacteria, and then a kind of isothiazolinone water treatment biocide of development.
The technical solution adopted in the present invention is as follows:
A kind of isothiazolinone water treatment biocide, it is characterized in that being made up of benzyl chloride, wetting agent, Trimethylamine, isothiazolinone, chlorine dioxide, deionized water, the percentage by weight of each component is:
Deionized water: 50%-75%
Benzyl chloride: 5%-12%
Wetting agent: 2%-4%
Trimethylamine: 6%-12%
Isothiazolinone: 1.5%-4.5%
Chlorine dioxide: 4%-8%.
Further, described a kind of isothiazolinone water treatment biocide be by percentage by weight be deionized water 60-75%, benzyl chloride 7%-8%, wetting agent 2%-3%, Trimethylamine 7%-8.5%, isothiazolinone 2.5%-3%, chlorine dioxide 5%-6% form.
Further, described wetting agent is the one in neopelex, water-solubleazone, spaonin powder.
A preparation method for isothiazolinone water treatment biocide, is characterized in that step is as follows:
Deionized water, benzyl chloride, wetting agent, Trimethylamine, isothiazolinone, chlorine dioxide are added stirred reactor by example successively in mass ratio, stir 30min, obtain light green color or blue liquid.
Beneficial effect of the present invention is:
A kind of isothiazolinone water treatment biocide non-corrosiveness of the present invention, nonirritant, non-foam, it is the regeneration product of oil field SRB bactericide, effectively can solve the resistance problems of sulfate reducing bacteria, and there is good compatibility, can effectively kill and suppress oil field sulfate reductive bacterium, be that a kind of to have height bactericidal effect, pH value be neutral environment-friendly type bactericide, product effect reaches domestically leading level.In addition, a kind of isothiazolinone water treatment biocide preparation technology of the present invention is simple to operate, and without any pollutant emission, reaction condition is gentle, and energy consumption is low.
