Abstract
The invention belongs to the technical field of water treatment, and particularly relates to a sterilizing stripper dedicated for oilfield injection water and a preparation method thereof. The sterilizing stripper dedicated for the oilfield injection water is characterized by compounding the following materials in percentage by weight: 15 to 35 percent of tetrakis hydroxymetyl phosphonium sulfuric, 10 to 35 percent of dodecyl dimethyl benzyl ammonium chloride, 0.5 to 1.0 percent of sodium dioctylsulfosuccinate, and the balance of deionized water. The preparation method comprises the following steps: adding the deionized water into a reaction kettle; and adding the tetrakis hydroxymetyl phosphonium sulfuric, the dodecyl dimethyl benzyl ammonium chloride and the sodium dioctylsulfosuccinate, and stirring for 40 to 50 minutes at normal temperature. By the method, the stripping performance of the sterilizing stripper and the killing performance to bacteria, particularly sulfate reducing bacteria, are improved; the sterilizing stripper has strong sterilization capability, good penetration and remarkable stripping effect; and the preparation process is simple and easy to operate.
Description
Technical field
The invention belongs to water-treatment technology field, be specifically related to a kind of oil field reinjection water special sterilizing remover and preparation method thereof.
Background technology
Oil-field flooding contains that greasy dirt, suspension and sulphide are higher, and COD is higher, and complicated component water quality inferiority, bacterial reproduction foundry loam grow seriously, sulfate reducing bacteria is many, endanger bigger.Used sterilization remover is peeled off not really ideal of effect at present, and is on the low side to the sulfate reducing bacteria killing rate.My company has carried out a series of research and test at the actual conditions of oil field reinjection water for this reason, has developed and mass-produced to be suitable for that oil field reinjection water is used, effect special use preferably and to peel off bactericide.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, and a kind of oil field reinjection water special sterilizing remover is provided, improved the sterilization remover stripping performance and to bacterium particularly sulfate reducing bacteria kill performance; The present invention provides its preparation method simultaneously.
Oil field reinjection water special sterilizing remover of the present invention is characterized in that forming by the material of following percentage by weight is composite:
Described tetra methylol sulfuric acid phosphorus is the commercially available prod, mass content 〉=75.0.
Described dodecyl benzyl dimethyl ammonium chloride is the commercially available prod, the mass content of active matter 〉=46.0.
Described dioctyl sodium sulfosuccinate is the commercially available prod, mass content 〉=60.0.
The preparation method is as follows for oil field reinjection water special sterilizing remover:
Add deionized water in reactor after, add tetra methylol sulfuric acid phosphorus, dodecyl benzyl dimethyl ammonium chloride and dioctyl sodium sulfosuccinate again, normal temperature stirs down and made in 40～50 minutes.
Oil field reinjection water special sterilizing remover of the present invention be a kind of develop at oil field reinjection water the composite product that forms of multiple component arranged.Each component has good concertedness, mutual aid and complementarity in this product:
Tetra methylol sulfuric acid phosphorus is a kind of wide spectrum, quick biocide, and it is also very remarkable to peel off effect, to control bacterium and the special economical and effective of algae, and effective unusually to killing of sulfate reducing bacteria, is called as the jinx of sulfate reducing bacteria.When using other biocide invalid, use it very effective usually.Still can play a role effectively in the higher complicated water quality of greasy dirt, suspension, though tetra methylol sulfuric acid phosphorus sterilization fast and effectively and peeling off is not long-acting biocide, the trihydroxy methyl oxidation that easily is oxidized to no biocidal active is seen; Dodecyl benzyl dimethyl ammonium chloride also is a kind of biocide of wide spectrum, have efficiently killing the bacterium algae, to foundry loam peel off and remove anhydrate in stink remarkable function is arranged, also all very high to heterotroph, iron bacteria, sulfate reducing bacteria sterilizing rate.But its usefulness reduces sometimes in complicated water body, and effect is not ideal enough; Dioctyl sodium sulfosuccinate has very high rapid osmotic power, lubricity, floating voltinism, helps very much to improve above both sterilization algae removal performance and foundry loam stripping performance.
Compared with prior art, beneficial effect of the present invention is as follows:
Oil field reinjection water special sterilizing remover of the present invention, improved the sterilization remover stripping performance and to bacterium particularly sulfate reducing bacteria kill performance, have that sterilizing power is strong, penetration good, it is remarkable to peel off effect, its preparation technology is simple and easy to implement.

Commercial Application example 1
Certain oil recovery factory, oil field two ore deposit thalliums, six multi-purpose stations will be handled from the gas, oil, the aqueous mixtures 23000m that recover the oil every day
3Be introduced into three phase separator (jar) after this mixture comes and carry out the separation of gas, oil, water, still contain a certain amount of oil in the water of separating, this water enters oil water separator (jar) again and carries out water-oil separating, the water of separating enters sedimentation basin, enters the water purification jar after precipitate and separate, in the water purification jar, treated oil in the water is separated once again from water, water enters surge tank by being pumped into the oil-extracting and water-injecting pipeline then, carries out oil-field flooding.
Though water filling is still oil-containing and impurity through repeatedly water-oil separating, precipitation process but in the water, COD is higher, and sulphide is higher, and (sulfide content 9.8mg/L, according to rower SY/T5329-94, when sulfide content during greater than 2.0mg/L, water body just belongs to high sulphide.), the microbial growth bacterial reproduction is heavier, and particularly sulfate reducing bacteria is higher, reaches 2.6 * 10
