Abstract

The invention provides a biological fungicide used in crude oil transportation pipelines, the main component of which is the alcanophoric bacteria of Berku Island, which has no pathogenicity; compared with conventional inorganic and organic fungicides, the amount of the biological fungicide is less, It is easy to use, environmentally friendly and green, and belongs to the environment-friendly fungicide. The biological bactericide of the invention can increase the pH in the environment, can effectively inhibit the microbial corrosion of metals, and the corrosion rate of X70 pipeline steel can be reduced by 200 times, and the bacteria are non-corrosive. With the prolongation of immersion time in the metal sample, its corrosion resistance will also increase. The principle of the biological bactericide of the present invention is to change the pH value so that it is not suitable for the survival of other microorganisms, and avoids the disadvantage that traditional bactericides are prone to drug resistance. The biological fungicide of the present invention is used for metal protection of crude oil transportation pipelines, and has simple operation and no requirements on the size and shape of the pipelines, as long as the fluid flows through, which can greatly reduce the cost of inhibiting microbial corrosion of pipelines for oil companies.

Description

technical field

[0001] The invention belongs to the field of environmental engineering, and in particular relates to a biological fungicide used for crude oil transportation pipelines and an application thereof. Background technique

[0002] Metal materials used in the environment of crude oil transportation pipelines are facing serious microbial corrosion problems. According to statistics, the corrosion of metal materials related to microorganisms accounts for 70%-80% of the total amount of metal materials. In crude oil transportation pipelines, microbial corrosion More serious, the corrosion perforation caused by it often leads to large-scale crude oil leakage, pollutes the environment, causes fluctuations in crude oil prices, and affects the national economy and people's livelihood. The annual energy consumption and corrosion losses caused by microbial corrosion are as high as hundreds of billions of dollars. A large part of this is caused by sulfate reducing bacteria (SR...
