Description
Technical field
The present invention relates to the water treatment fields in oil field, more particularly to a kind of oil field Compositional type fungicide and preparation side
Method.
Background technique
In the secondary oil recovery of oil field, a large amount of reinjected waters are needed, due to generally all containing sulfate reducing bacteria in reinjected water
(SRB), saprophytic bacteria (TGB) and iron bacteria (FB) etc. easily cause metal erosion, formation blockage, chemical agent rotten etc. a series of unfavorable
In the bacterial micro-organism of water flood recovery.Reinjected water contains higher calcium ions and magnesium ions simultaneously, the bacterium in reinjected water easily and calcium and magnesium from
Son combines, and blocks so as to cause waterflood-transmission line and formation scaling, these all cause huge economic loss to oil field production run.
Therefore, it is typically necessary and adds fungicide before produced-water reinjection and pre-processed.
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；Meanwhile the vitality of bacterium is extremely strong, any one is killed
Microbial inoculum using the time it is long can all make bacterial resistance occurred, cause the germicidal efficiency of fungicide decline, dose increase the problems such as, this
Sample just considerably increases the use cost of fungicide, under the premise of current Crude Oil Market is still sluggish, needs constantly to develop
Develop new oil field fungicide.
Summary of the invention
The present invention is directed to above-mentioned technical problem of the existing technology, provide it is a kind of it is at low cost, bactericidal effect is good
Oil field Compositional type fungicide and preparation method.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that
A kind of oil field Compositional type fungicide, based on the gross mass of the Compositional type fungicide, it includes following components:
(1) 70% water；
(2) dodecyl benzyl dimethyl ammonium chloride of 23%-27%；
(3) remaining is the poly- hexamethyl guanidine of hydrochloric acid.
Further, the Compositional type fungicide the preparation method comprises the following steps: at room temperature, according to the proportion by dodecyl dimethyl
Benzyl ammonium chloride and polyhexamethylene guanide are successively dissolved in the water, and then stir evenly, and obtain oil field Compositional type fungicide.
Further, at room temperature, 27% dodecyl benzyl dimethyl ammonium chloride and 3% salt are added in 70% water
The poly- hexamethyl guanidine of acid, and mechanical stirring is uniform.
Further, at room temperature, 25% dodecyl benzyl dimethyl ammonium chloride and 5% salt are added in 70% water
The poly- hexamethyl guanidine of acid, and mechanical stirring is uniform.
Further, at room temperature, 23% dodecyl benzyl dimethyl ammonium chloride and 7% is added in 70% water
The poly- hexamethyl guanidine of hydrochloric acid, and mechanical stirring is uniform.
The advantages and positive effects of the present invention are:
Oil field of the invention is poly- using dodecyl benzyl dimethyl ammonium chloride, the hydrochloric acid of low cost with Compositional type fungicide
Hexamethyl guanidine and water are matched and carry out sterilization verifying, the results showed that Compositional type fungicide bactericidal effect of the invention is good,
Better than glutaraldehyde and THPS, conducive to improving the quality of reinjected water, can be in oil field to guarantee the normal production run in oil field
Water treatment field wide popularization and application.

Three kind Compositional type fungicide of the embodiment one into embodiment three, ingredient is identical but proportion is different, wherein Compositional type
The bactericidal effect of fungicide BCW-03 is best, but since the cost of the poly- hexamethyl guanidine of hydrochloric acid is higher than dodecyl dimethyl benzyl chloride
Change ammonium, the poly- hexamethyl guanidine dosage of preferred hydrochloric acid is few in practical application and bactericidal effect meets the Compositional type fungicide BCW- needed
02。
Comparative example
The present embodiment carries out Contrast on effect to Compositional type fungicide BCW-02 and other two kinds of common fungicide:
According to method specified in SY/T5329-2012 standard, takes 100mL water sample to be divided into three parts, be added in a water sample
Be added in a certain amount of fungicide BCW-02, a water sample a certain amount of glutaraldehyde, be added in a water sample it is a certain amount of
Medicament in three parts of water samples is diluted to 7ppm according to dilution-to-extinction method by THPS；Then three kinds of samples are placed in insulating box
Cultivated together with bacterium, specifically, each filling concentration sample respectively with sulfate reducing bacteria (SRB), saprophytic bacteria
(TGB) it is cultivated 7 days with iron bacteria (FB), cultivation temperature is set as 65 ± 5 DEG C；Total number of bacteria is measured after 7 days, and sterilization is calculated
Rate the results are shown in Table 4:
The bactericidal effect comparison of the different fungicide of table 4
As can be seen from example 4 that: in glutaraldehyde, THPS, BCW-02 this 3 kinds of fungicide, Compositional type fungicide BCW-
02 sterilizing rate highest is obvious compared to other two kinds of medicament disinfecting effects.Therefore, it is possible to judge that can attempt to be answered at the scene
With.The application of oil field of the invention Compositional type fungicide, be the Compositional type fungicide to sulfate reducing bacteria, saprophytic bacteria and
Iron bacteria has bacteriostasis, can apply in the water treatment field of oil field.
