Abstract
The invention provides a compound bactericide used in oilfield flooding, relating to oilfield water treatment. The bactericide comprises the following components by weight percent: 50-60% of deionized water, 5-10% of surfactant, 25-30% of quaternary phosphonium salt and 5-10% of methylene dithiocyanate. The bactericide used in oilfield flooding can act under the conditions of high hardness, high alkalinity and high temperature, has good bactericidal effects on fungi and slime saprophytic bacteria, especially has terrific treatment effects on sulfate reducing bacteria, has long bactericidal efficiency duration, can effectively maintain reproduction of microorganisms in oil wells and can be widely used in the fields of oilfield flooding and sewage treatment in the oilfield industry.
Description
Technical field
The present invention relates to water treatment field, relate to specifically oil-field flooding bactericide.
Background technology
In the secondary oil recovery of oil field, need a large amount of water fillings, in flood pattern, contain various microorganisms as sulfate reducing bacteria (SRB), saprophytic bacteria (TGB) and iron bacteria etc., they are in growth, metabolism, reproductive process, can cause heavy corrosion the blocking pipe of the metal materials such as drilling-production equipment, waterflood-transmission line, infringement oil reservoir, causes water injection rate, oil production rate, oil gas Quality Down, also for crude oil processing brings exceptional hardship, cause great economic loss.Therefore, generally all need to before water filling, add bactericide and carry out pretreatment.The bactericide that oil field is used is at present all generally the medicament of continuing to use domestic use of water and industrial circulating water, by its sterilization mechanism, can be divided into aerobic type bactericide and non-oxygen type bactericide.Due to oil field environment and different to the requirement of water quality, the kind of bacterium and harm thereof are different, therefore also different to the performance requirement of bactericide.
Maximum bacterium is endangered in oil field sulfate reducing bacteria, iron bacteria and saprophytic bacteria, therefore, selects bactericide to start with for these bacteriums.Sulfate reducing bacteria is anaerobic bacteria, and oxidable carbon containing organic compound or hydrogen, sulphate reducing produce H
2s.Corrosion product FeS again can blocking pipe and water injection well.Because the harm of sulfate reducing bacteria is maximum, almost hinder and recover the oil in all its bearings, so people take much count of the research to it in recent years, as found the new bacterial strain of sulfate reducing bacteria, the scope of its oxidation carbonaceous organic material etc.Saprophytic bacteria claims again mucus to form bacterium, it is aerobic heterotroph, it is secreted a large amount of mucus and is attached on pipeline and equipment, cause biofouling to stop up water injection well and filter, meanwhile, also can produce oxygen concentration cell and cause the corrosion of e-quipment and pipe and the environment etc. of existence, breeding is provided to sulfate reducing bacteria.Wherein most important saprophytic bacteria-iron bacteria is the Duo Muduo section bacterium that distributes very wide, it is mainly that ferrous oxidation is become to high price iron, the energy that utilizes iron oxidation to discharge meets the needs of its existence, its general saprophytic bacteria of hazard ratio harm large, the bacterial classification of selecting while detecting fungicide effect often.The vitality of bacterium is extremely strong, and any bactericide service time is long all can make bacterium develop immunity to drugs, and causes the problems such as germicidal efficiency decline, dose increase of bactericide, therefore, need to constantly develop new oil field bactericide.China is making extensive work aspect the research and development of oil field bactericide, still take at present SAA series bactericidal agent as main.
Summary of the invention
The present invention is directed to the shortcoming of above-mentioned existence, a kind of Compositional type oil-field flooding bactericide is provided.
Compositional type oil-field flooding bactericide comprises deionized water, surfactant, season phosphonium salt, dithiocyano-methane.The percentage by weight of each component is:
Deionized water 50-60%
Surfactant 5-10%
Season phosphonium salt 25-30%
Dithiocyano-methane 5-10%
This oil-field flooding bactericide can act under high rigidity, high alkalinity, high-temperature condition, and good to fungi, foundry loam saprophytic bacteria bactericidal effect, particularly processing sulfate reducing bacteria has fabulous effect.The germicidal efficiency duration is long, can effectively maintain the breeding of the microorganism in oil well.This product can be widely used in sewage treatment area in oil-field flooding and oilfield applications.
embodiment
Embodiment 1:
Choose by weight percentage raw material
Deionized water 60%
Sodium hexadecyl sulfate 8%
Tetrakis hydroxymetyl phosphonium sulfuric 27%
Dithiocyano-methane 5%
Embodiment 2:
Choose by weight percentage raw material
Deionized water 55%
Lauryl sodium sulfate 10%
Tetra methylol phosphonium chloride 30%
Dithiocyano-methane 5%
Embodiment 3:
Choose by weight percentage raw material
Deionized water 55%
Sodium hexadecyl sulfate 8%
Tetra methylol phosphonium chloride 30%
Dithiocyano-methane 7%
application test and result
Medicament and single season phosphonium salt bactericidal effect contrast table 1
The bactericidal effect contrast of table 1 medicament and single quaternary alkylphosphonium salt
2. the bactericidal effect contrast table 1 of embodiment and single quaternary ammonium salt
The bactericidal effect contrast of table 2 embodiment and single quaternary ammonium salt
as can be seen from the above table, the product of embodiments of the invention 1, embodiment 2, embodiment 3 is excellent to the bactericidal effect of sulfate reducing bacteria, much larger than current conventional non oxidizing bactericide, has reached the requirement of the present invention to sulphate bactericidal effect completely.
Claims (3)
1. Compositional type oil-field flooding bactericide comprises deionized water, surfactant, season phosphonium salt, a dithiocyano-methane, and the percentage by weight of each component is:
