Paragraph 0089-0091, (2020/06/16)
The invention discloses a corrosion inhibition bactericide and a preparation method thereof, and a corrosion inhibition bactericide for CO2 flooding production well, and belongs to the field of oilfield chemistry. The corrosion inhibition bactericide comprises an imidazoline quaternary ammonium salt modified product, dodecyl dimethyl benzyl ammonium chloride, dithiocyano-methane and an anti-freezing agent according to a mass ratio of (3-5):(1-2):(0.1-0.3):(3-6), the chemical structural formula of the imidazoline quaternary ammonium salt modified product is defined in the specification, and inthe formula, R is branched hydrocarbon containing 12-17 carbon atoms, and n is any positive integer from 2 to 5. The corrosion inhibition bactericide has excellent corrosion inhibition, sterilizationand anti-freezing properties, and can be applied to corrosion prevention and sterilization environments of high and cold and winter low-temperature environments.
