Embodiment 1

[0015] Example 1 (making 100g composition)

[0016] Ground water or tap water is filtered and ultra-filtered to obtain production water. Put the production water into the reactor, add 25g of Zinc and fully stir the reaction for more than 10 minutes, then add 8g of prochloraz in the reactor, stir and react for more than 15 minutes, then add chlorothalonil 15g, after stirring for more than 10 minutes, make up the total amount with process water to obtain the product.

Embodiment 2

[0017] Example 2 (100g composition)

[0018] Ground water or tap water is filtered and ultra-filtered to obtain production water. Put the production water into the reactor, add 55g of Zinc and fully stir the reaction for more than 10 minutes, then add 5g of prochloraz in the reactor, and add chlorothalonil after stirring for more than 15 minutes 5g, after stirring for more than 10 minutes, make up the total amount with process water to obtain the product.

Embodiment 3

[0019] Example 3 (making 100g composition)

[0020] Ground water or tap water is filtered and ultrafiltered to obtain production water. Put the production water into the reactor, add 10g of Zinc and fully stir the reaction for more than 10 minutes, then add 10g of prochloraz in the reactor, and add chlorothalonil after stirring for more than 15 minutes 20g, after stirring for more than 10 minutes, make up the total amount with process water to obtain the product.

Abstract

The invention discloses a bactericidal composition for reinjection water in oil fields, which is composed of zinc, prochloraz, chlorothalonil and water with bactericidal effect, and the weight percentage of each component is composed of: zinc 10 -55%, prochloraz 5-10%, chlorothalonil 5-20%, and make up the balance with water. The invention has the advantages of providing a broad-spectrum, high-efficiency, and low-toxicity bactericidal composition, which improves the efficacy of each drug, reduces the amount of use, and does not cause corrosion by multiple instruments, does not harm plants, and does not pollute The environment has dual functions of antibacterial and bactericidal. It can effectively kill various microorganisms in the reinjection water of the oil field, and protect the instruments in the oil field from being damaged.

Description

Technical field [0001] The invention belongs to the technical field of bactericides for oil fields, and particularly relates to a bactericidal composition used for oil field reinjection water. Background technique [0002] After the oilfield is put into development, as the exploitation time increases, the energy of the oil layer itself will continue to be consumed, causing the pressure of the oil layer to continue to drop, the underground crude oil is largely degassed, the viscosity increases, the oil well production is greatly reduced, and even the spraying and production will be stopped, causing underground A large amount of dead oil cannot be recovered. In order to make up for the underground deficit caused by crude oil production, maintain or increase the pressure of the oil layer, achieve high and stable production of the oil field, and obtain a higher recovery rate, it is necessary to inject water into the oil field. [0003] Oilfield water injection method: The water inject...
