Abstract
The invention relates to a compound bactericide for an oilfield flooding system, belonging to the technical field of oilfield sewage treatment. The compound bactericide for an oilfield flooding system is characterized by comprising the following components in percentage by weight: 70-80% of 45-55% (mass percent) benzalkonium chloride water solution, 10-20% of 25-35% (mass percent) cetylpyridinium bromide ethanol solution and 10-15% of 18-22% (mass percent) tetrachloroisophthalonitrile xylene solution. The compound bactericide for an oilfield flooding system has very high bactericidal effect, can effectively remove sulphate reducing bacteria, iron bacteria and saprophytic bacteria in the sewage and prevent the bacteria from corroding and blocking pipeline equipment, and has the advantages of simple components, convenient preparation, quick and efficient action, low cost, high bactericidal rate, low consumption, small side effect and the like.
Description
Technical field
The invention belongs to disposing polluted water in oil technical field, particularly relate to a kind of oil field flood pattern Compositional type bactericide.
Background technology
At present, in oilfield produced water system, in the flood pattern of mainly return water, due to the existence of microorganism, bring great harm to field produces.Wherein endanger sulfate reducing bacteria most serious of all, its product hydrogen sulphide is to corrosion of metal especially severe, and product iron sulfide is again the material causing pipeline to block.Next to produce muciferous saprophytic bacteria and iron bacteria, after the quantity of these bacteriums exceedes certain value, can produce difference in oxygen concentration corrosion cell, cause water injection well to block, injection rate reduction etc.
In oil field flood pattern, for preventing bacterium to pipeline and the problem such as the corrosion of equipment and the blocking of generation, the growth of anti-bacteria of must taking measures.The growth of anti-bacteria, the easiest implementation method is exactly reasonable employment chemical agent.For to kill or to suppress the chemical agent of growth of microorganism to have a variety of, to the size of microbicidal effect, because of chemical agent toxicity and enter the permeability of cell and the kind of microorganism and variant, simultaneously also by the impact of environmental factor.A kind of chemical agent is toxic for a certain microorganism, may not affect, be even utilized as nutriment for another kind of microorganism.Some medicament plays bactericidal action when concentration is slightly high, but when certain low concentration, has stimulation growth on the contrary.Therefore only have correct choice and operation bactericide, effectively could suppress the breeding of microorganism.
But in prior art there is consumption greatly in usual adopted bactericide, the technical problems such as sterilizing rate is low, and side effect is large.
Summary of the invention
The present invention provides a kind of oil field flood pattern Compositional type bactericide for solving in known technology the technical problem that exists.
The object of this invention is to provide a kind ofly have that component is simple, the oil field flood pattern Compositional type bactericide of preparation efficient, with low cost, the feature such as sterilizing rate is high, usage amount is low, side effect is little easily and fast.
The bactericide benzalkonium chloride that in the middle of sewage treatment process, routine uses, brocide primary attachment, at bacterial cell surface, cell surface are formed a high concentration example group, thus directly affect cell membrane normal function.Film changes electrical conductance, surface tension, dissolubility after being sterilized agent absorption, and forms complex compound, makes protein denaturation, suppresses or sting kinase whose activity, controls the plasmalemma of infringement cell permeability, thus makes bacterium lethal.This kind of medicament dosage is bigger than normal, and sterilizing rate is not high.Another kind of termil has stronger osmosis, and the cell wall by cell enters into cytoplasm, destroys endobacillary biosynthesis, thus playing bactericidal action, this kind of medicament disinfecting rate is high, but side effect is stronger, biological degradability is poor, does not widely use.For the pluses and minuses of this several medicament, the present invention adopts the method for three kinds of medicament mechanical mixture, and obtained oil field flood pattern Compositional type bactericide, have bactericidal effect good, chemical feeding quantity is low, the remarkable performance of the very little grade of side effect.
Oil field flood pattern bactericide of the present invention, its composition percentage by weight is: benzalkonium chloride (mass fraction 50% aqueous solution) 70-80%, brocide (ethanolic solution of mass fraction 30%) 10-20%, termil (mass fraction 20% xylene solution) 10-15%.
The structural formula of benzalkonium chloride is:
The structural formula of brocide is:
The structural formula of termil is:
The technical scheme that oil field flood pattern Compositional type bactericide of the present invention is taked is:
A kind of oil field flood pattern Compositional type bactericide, be characterized in: the percentage by weight of oil field flood pattern Compositional type bactericide consists of the aqueous solution 70-80% that benzalkonium chloride mass fraction is 45-55%, brocide mass fraction is the ethanolic solution 10-20% of 25-35%, and termil mass fraction is the xylene solution 10-15% of 18-22%.
Oil field flood pattern Compositional type bactericide of the present invention can also adopt following technical scheme:
Described oil field flood pattern Compositional type bactericide, is characterized in: oil field flood pattern Compositional type bactericide adopts the mode of the aqueous solution of mechanical mixture benzalkonium chloride, the ethanolic solution of brocide and the xylene solution of termil to make.
The advantage that the present invention has and good effect are:
Oil field flood pattern Compositional type bactericide is owing to have employed the brand-new technical scheme of the present invention, compared with prior art, the sulfate reducing bacteria in oil field flood pattern of the present invention, iron bacteria, saprophytic bacteria have efficiently kills effect, has consumption few, cost is low, the little grade advantage of toxic and side effect.
