Description
Technical field
The invention belongs to oil field chemical agent and preparing technical field, and in particular to one kind is used for polymer-containing sewage in oil field and handled
Bactericide and preparation method thereof.
Background technology
Polymer displacement of reservoir oil tech is the tertiary oil recovery technology that China is widely used at present, but produces largely recovered the oil containing poly- therewith
Sewage, COD in polymer-bearing waste-waterCR、BOD5It is higher than conventional produced water, it is more beneficial for the growth of harmful bacteria, especially SRB bacterial populations
Amount will be higher by several orders of magnitude of conventional produced water.At present in polymer-bearing waste-water handling process, control bacterial reproduction is indispensable
Link, such as deal with improperly, the bacterium meeting amount reproduction in produced-water reinjection system, cause the rise of water quality corrosion rate, suspension liter
The high consequence deteriorated along journey, impurities in water blocks formation pore after water quality deterioration can cause produced-water reinjection stratum, so as to reduce
Water injection capacity and oil well output.
At present, using bactericide technology mode is added, bactericide uses for control of the polymer-containing sewage in oil field for harmful bacteria
Be cationic, such as mono-quaternaries, polyquaternium, single guanidine, poly- guanidine, due to containing strong positive electricity in this kind of biocide molecules
Lotus, the biocide molecules with strong positive charge can produce precipitation with polymer molecule negatively charged in sewage；On the one hand cause
Suspension increase in water, on the other hand reduce the bactericidal effect of bactericide.
The content of the invention
The present invention provides a kind of bactericide and its system for polymer-containing sewage in oil field processing in view of the shortcomings of the prior art
Preparation Method.Positive charge disperses in the molecular structure of the polymer-containing sewage in oil field bactericide of the present invention, good with the compatibility of polymer-bearing waste-water；
The biocide molecules both ends of the present invention are lipophilic group, interposition hydrophilic group, the good penetrability of molecule；Meanwhile sterilization of the invention
The advantages of agent raw material is easy to get, and synthetic method is simple and cost is low.
The present invention offer it is a kind of for polymer-containing sewage in oil field processing bactericide, described bactericide by halogenation benzyl,
Polyethylene polyamine reaction forms.
Preferably, the mol ratio of polyethylene polyamine of the present invention and halogenation benzyl is 1：2.0~2.2, preferably 2.0.
Preferably, halogenation benzyl of the present invention is benzyl chloride or cylite.
Preferably, polyethylene polyamine of the present invention is in diethylenetriamine, triethylene tetramine and TEPA
It is a kind of.
The molecular structural formula of described bactericide is as follows：
Wherein：N=1~3, preferably 2.
It is another object of the present invention to provide it is a kind of for polymer-containing sewage in oil field processing bactericide preparation side
Method, its specific preparation method are as follows：
(1) in there-necked flask, reaction medium is firstly added, is then slowly added into the polyethylene polyamine of aforementioned proportion, more second
Alkene polyamines begins heat to 30~40 DEG C after the completion of adding, and under the conditions of stir speed (S.S.) is 150~200rpm stirring 10~
20min；
(2) opened using separatory funnel toward the halogenation benzyl that aforementioned proportion is slowly added dropwise in above-mentioned there-necked flask after being added dropwise to complete
Agitator, stir speed (S.S.) are 100~150rpm, and mixed solution is obtained after stirring 20~25min；
(3) above-mentioned mixed solution is warming up to 50~70 DEG C, reacted while stirring, stir speed (S.S.) is 200~300rpm, instead
It is 1.0~1.5h between seasonable, after the reaction time terminates, obtains the crude product of the present invention；
(4) above-mentioned crude product is diluted with water to the solution that mass concentration is 20~40%, is the product of the present invention.
Preferably, described reaction medium is one kind in water, low mass molecule alcohol and ether.
Described reaction medium dosage is 8~10 times of polyethylene polyamine quality.
Described reaction equation is as follows：
The present invention has the following advantages that compared with prior art and beneficial effect：
(1) positive charge disperses in biocide molecules structure of the invention, good with the sewage compatibility containing polymer, will not
Cause the increased phenomenon of suspension in sewage；
(2) biocide molecules both ends of the invention are lipophilic group, interposition hydrophilic group, the good penetrability of molecule；
(3) material of germicide of the invention is easy to get, and synthetic method is simple, and cost is low, and bactericidal effect is good, and sterilizing rate is more than
98.0%.
This bactericide belongs to organic amine bactericide, and molecule carries electropositive.Because microorganism surface carries elecrtonegativity,
The bactericide can be adsorbed with electronegative phage surface, and one layer of barrier film is produced in bacterium surface；Made by diffusion
Bacterium surface is embedded in through cell membrane, its hydrophobic side, bacterium is produced and stops up inhibition effect, thanks to noxious material row and is hindered
Hinder, therefore make protein denaturation on cell membrane；Cell membrane is made up of phospholipid bilayer molecule, the water-wet side and surface-active of phospholipid molecule
The hydrophilic group of agent is had an effect, and changes the permeability of film；With being incremented by for concentration, the gradual solubilized cell membrane of surfactant,
Until phosphatide touches the hydrophobic group of surfactant, the leakage of the materials such as Dissolve things inside such as K+, DNA, RNA is caused；Concentration is bigger
When, surfactant causes thalline dead by penetration cell film, with the effect of cell Dissolve things inside.
