[0029] Specifically, the preparation method of the above biofouling cleaning agent includes: according to the mass percentage of each component in the biofouling cleaning agent, hydrochloric acid, hydrofluoric acid, a compound of methylpentynol and Mannich base, three Ferric chloride, 2-iodobenzoic acid, heptadecenyl imidazoline quaternary ammonium salt, and phosphonoglycolic acid are slowly added into water, and after stirring evenly, a biofouling cleaning agent is obtained.
[0030] On the other hand, an embodiment of the present invention provides an application of the above-mentioned biofouling cleaning agent in treating biofouling in an oil field water injection pipe network.
[0031] Specifically, the steps of using the biofouling cleaning agent provided by the embodiments of the present invention to treat the oilfield water injection pipeline network include:
[0032]101. According to the pipe diameter, length, and fouling degree, determine the concentration and dosage ...
Embodiment 1
[0042] This embodiment provides a biofouling cleaning agent, comprising the following components in mass percentage: 4% hydrochloric acid, 0.6% hydrofluoric acid, 1% compound of methylpentynol and Mannich base, trichlorohydrin 2.5% iron oxide, 1% 2-iodobenzoic acid, 0.6% heptadecenyl imidazoline quaternary ammonium salt, 0.5% phosphonoglycolic acid, and the balance is water. Wherein, in the compound of methylpentynol and Mannich base, the mass ratio of methylpentynol to Mannich base is 1:9.
