Abstract

The present invention relates to one kind of paint for pipeline capable of resisting corrosion of sulfate reducing bacteria and its production process. The paint consists of two liquid components, including component A and component B, to be mixed in use. The component A is produced through adding modified phenol phenolic aldehyde type epoxy resin and bisphenol type epoxy resin into mixed solvent; adding chrome oxide green, precipitated barium sulfate, graphite and other seven kinds of material; mixing through stirring and grinding. The component B is produced through adding mannis added and modified polybasic amine into mixed solution. The paint is applied to the inner wall of oil field pipeline to prevent corrosion of sulfate reducing bacteria.

Description

technical field [0001] The invention relates to a gathering and transportation pipeline coating resistant to sulfate-reducing bacteria corrosion and a manufacturing method, which is used for anti-corrosion on the inner walls of water injection well oil pipes and gathering and transportation pipelines in oil and gas fields containing high sulfate-reducing bacteria. Background technique [0002] The existing development of high sulfate-reducing bacteria oil and gas fields adopts the methods of adding fungicides, corrosion inhibitors, and using steel materials resistant to sulfate-reducing bacteria to prevent internal corrosion of oil pipes and gathering pipelines. The disadvantages are that it is inconvenient to use and high in cost; Some epoxy resin coatings used for anti-corrosion on the inner walls of oil pipes and gathering pipelines have insufficient corrosion resistance to sulfate-reducing bacteria. Contents of the invention [0003] The technical problem to be solved ...
