Description
Technical field
The invention belongs to field of oilfield chemistry, and in particular to a kind of oil field Compositional type bactericide and preparation method thereof.
Background technology
In today's society, fossil fuel is still the main force of energy field, and crude oil in national product field still
Play the role of very important.There is much harmful bacterium, such as sulfate reducing bacteria in the production process of crude oil
(SRB), iron bacteria (TGB), saprophytic bacteria (FB) etc., wherein harmfulness maximum are sulfate reducing bacterias, sulfate reducing bacteria
Raised growth can cause the blocking and the reduction of oil reservoir void permeabilities of pipeline.In addition, the hydrogen sulfide that SRB is produced can cause drilling to set
The corrosion of standby, pipeline and equipment, these, which corrode, adds high cost to crude oil production.
With the development of two tertiary oil recovery technologies, most oil fields come into high water-cut stage, and oil field mining liquid is aqueous
The raising of rate, and suitable breeding farm condition in one's power is provided to bacterium, this undoubtedly adds extent of corrosion again.International oil price is low
Fan, in order to pull through their difficulties, CNOOC has also been proposed the measure of cost efficiency, therefore develops a kind of efficient and economic bactericide just
Seem particularly necessary.
The content of the invention
The purpose of the present invention is that there is provided a kind of oil field Compositional type bactericide and its preparation side in view of the shortcomings of the prior art
Method.The present invention has stronger bactericidal properties to sulfate reducing bacteria, iron bacteria, saprophytic bacteria, and bactericidal effect is obvious, application
Extensively, raw material is easy to get, and low with cost, the advantages of usage amount is small.
For achieving the above object, the present invention is adopted the following technical scheme that:
A kind of oil field Compositional type bactericide, the Compositional type bactericide includes following components, according to mass fraction meter:
The bromo- malonamide 10wt%-15wt% of 2,2- bis-;
Tetra methylol phosphonium bromide 15wt%-20wt%;
Glutaraldehyde 10wt%-15wt%;
Surplus is water.
The structural formula of the bromo- malonamides of 2,2- bis- is as follows:
It is preferred that, using pH value regulator, the pH value of Compositional type bactericide is adjusted to 7-9.
It is used as preferred technical scheme:
Present invention also offers a kind of preparation method of oil field with Compositional type bactericide, by the bromo- malonamides of 2,2- bis-, four
Methylol phosphonium bromide and glutaraldehyde, which are sequentially added in water, to stir, and then adjusts pH value to 7-9 with alkaline hydrated oxide.
It is preferred that, the alkaline hydrated oxide is sodium hydroxide or potassium hydroxide.
It is preferred that, mechanical agitation is used during stirring, churned mechanically speed is 2000-2500rpm.
Inventive principle:
The action principle of bactericide generally comprises following two:1st, the generation of energy in bacterial reproduction is suppressed.2nd, bacterium is disturbed
The synthesis of body living matter.The bromo- malonamides of 2,2- bis-, tetra methylol phosphonium bromide and glutaraldehyde in this Compositional type bactericide,
Every kind of material is respectively provided with certain bactericidal action, and triplicity has the effect mutually cooperateed with, so as to be imitated with more excellent sterilization
Really.
The reason for present invention regulation pH to 7-9 is that within this range, the damage to oil field equipment is minimum.When pH be less than 7 or
When person pH is more than 9, certain corrosion can be produced to oil field equipment, these corrosion products can be deposited in equipment, the extra large pipe of increase
Pressure, shortens the service life of equipment, and then increases the cost of production of hydrocarbons, has run counter to the original intention of extra large oily cost efficiency.
Beneficial effect:
The oil field of the present invention is sterilized with Compositional type has stronger bactericidal properties to sulfate reducing bacteria, iron bacteria, saprophytic bacteria,
Bactericidal effect substantially, has a wide range of application, raw material is easy to get, and low with cost, the advantages of usage amount is small.
