Abstract
The invention discloses a bactericide for oil well sulfate reducing bacteria corrosion, which is applied to corrosion inhibition and corrosion prevention of oilfield oil extraction equipment. The bactericide comprises the following components by weight percent: 4.75 to 5.0 percent of hexamine, 23.75 to 24.25 percent of bactericide TS-781, 5.25 to 5.5 percent of dodecyl quaternary ammonium inner salt ampholytic surfactant, 3.75 to 4.0 percent of cetyl ampholytic surfactant, 2.75 to 3.0 percent of dimethyl cetyl ethylene sulfite quaternary ammonium inner salt, 0.005 to 0.006 percent of fluorocarbon surfactant FN-2, 25 to 30 percent of methanol, 0.001 to 0.0015 percent of vitamin D, and the balance of water. The bactericide has the advantages that the bactericide is added into an oil well; and under the condition that the ratio of the adding weight of the bactericide to the volume of produced liquid is 20 to 30mg/l, the corrosion inhibition rate of the oil well reaches over 90 percent.
