Abstract
The invention relates to the technical field of water treatment chemicals, in particular to a bactericide for oilfield water injection and a manufacturing method thereof. The bactericide comprises the following components in part by weight: 10 to 30 parts of 2 percent chlorine dioxide solution, 5 to 15 percent of 27.5 percent hydrogen dioxide solution, 8 to 15 parts of dodecyl dimethyl ammonium chloride and 100 to 130 parts of distilled water. The bactericide is a novel low-cost bactericide prepared for treating bacteria most harmful to oilfield, such as sulfate reducing bacteria, iron bacteria and saprophytic bacteria.
Description
Technical field
The present invention relates to the water treatment agent technical field, especially a kind of oil-field flooding bactericide and manufacturing approach thereof.
Background technology
In the secondary oil recovery of oil field; Need a large amount of re-injection water, owing to generally all contain a series of bacterial micro-organisms that are unfavorable for water flood recovery such as be prone to cause that metal erosion, formation blockage, chemical agent go bad such as sulfate reducing bacteria (SRB), saprophytic bacteria (TGB) and iron bacteria in the re-injection water.The water of re-injection simultaneously contains higher calcium ions and magnesium ions, is prone to produce waterflood-transmission line and the serious fouling in stratum, thereby causes waterflood-transmission line and formation blockage.These cause enormous economic loss all for the oil field production run.Therefore, generally all bactericide need before produced-water reinjection, be added and corrosion inhibiting and descaling agent carries out preliminary treatment.The employed bactericide in oil field generally all is a medicament of continuing to use domestic use of water and industrial circulating water at present, can be divided into aerobic type bactericide and non-oxygen type bactericide by its sterilization mechanism.Because oil field environment and different to requirements in water quality, kind of bacterium and harm thereof are different, so also different to the performance requirement of bactericide.
Summary of the invention
The object of the present invention is to provide a kind of oil-field flooding bactericide and manufacturing approach thereof; Mainly solve above-mentioned existing in prior technology problem, it is sulfate reducing bacteria, iron bacteria and saprophytic bacteria to be arranged and the bactericide of a kind of novel low-cost of developing to the maximum bacterium of oil field harm.
For realizing above-mentioned purpose, the present invention realizes like this.
A kind of oil-field flooding bactericide is characterized in that: it is according to 10～30 parts of the ClO 2 solutions that consists of 2% concentration of parts by weight, 5～15 parts of the hydrogenperoxide steam generators of 27.5% concentration, 8～15 parts of dodecyl dimethyl ammonium chlorides, 100～130 parts of distilled water.
A kind of manufacturing approach of aforesaid oil-field flooding bactericide; It is characterized in that: earlier distilled water is added in the reaction vessel; Then chlorine dioxide, hydrogen peroxide, dodecyl dimethyl ammonium chloride are added in the reaction vessel successively, and stir after 30 minutes and get product.
The advantage that prescription of the present invention and method can embody is.
1, employed chlorine dioxide can kill sulfate reducing bacteria, iron bacteria in the cycle water of oil field in the disclosed a kind of oil-field flooding bactericide of the present invention, controls their corrosion to pipeline.
2, employed hydrogen peroxide mainly plays the sterilization algae removal effect in the disclosed a kind of oil-field flooding bactericide of the present invention, and the oil-containing water in the oil field reinjection water system is had the effect of oxidative decoloration, deodorizing, dechlorination, sulphur removal.
3, employed dodecyl dimethyl ammonium chloride has strong sterilizing ability to heterotrophic bacteria, iron bacteria, sulfate reducing bacteria in the disclosed a kind of oil-field flooding bactericide of the present invention; The ability that also has washing oil simultaneously; Reduce the oil saturation of core, improve the permeability of water, be beneficial to water filling.
Embodiment
Embodiment 1: earlier 100 parts of distilled water are added in the reaction vessel; Then the hydrogenperoxide steam generator of the ClO 2 solution of 10 part of 2% concentration, 5 part of 27.5% concentration, 8 parts of dodecyl dimethyl ammonium chlorides are added in the reaction vessel successively, and stir after 30 minutes and get product.
Embodiment 2: earlier 120 parts of distilled water are added in the reaction vessel; Then the hydrogenperoxide steam generator of the ClO 2 solution of 20 part of 2% concentration, 10 part of 27.5% concentration, 12 parts of dodecyl dimethyl ammonium chlorides are added in the reaction vessel successively, and stir after 30 minutes and get product.
Embodiment 3: earlier 130 parts of distilled water are added in the reaction vessel; Then the hydrogenperoxide steam generator of the ClO 2 solution of 30 part of 2% concentration, 15 part of 27.5% concentration, 15 parts of dodecyl dimethyl ammonium chlorides are added in the reaction vessel successively, and stir after 30 minutes and get product.
Being merely preferred embodiment of the present invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should be technological category of the present invention.
Claims (2)
1. oil-field flooding bactericide; It is characterized in that: it is according to 10～30 parts of the ClO 2 solutions that consists of 2% concentration of parts by weight; 5～15 parts of the hydrogenperoxide steam generators of 27.5% concentration, 8～15 parts of dodecyl dimethyl ammonium chlorides, 100～130 parts of distilled water.
2. the manufacturing approach of an oil-field flooding bactericide as claimed in claim 1; It is characterized in that: earlier distilled water is added in the reaction vessel; Then chlorine dioxide, hydrogen peroxide, dodecyl dimethyl ammonium chloride are added in the reaction vessel successively, and stir after 30 minutes and get product.
