Abstract

The invention relates to a wear-resistant, high-temperature resistant and anti-corrosion coating for sand-containing heavy oil gathering pipelines and a preparation method thereof. Methylphenyl silicone resin and bisphenol A epoxy resin E-44 are added into mixed solution of dimethylbenzene, diacetone alcohol, cyclohexanone and dimethyl dicarboxylic acid; the mixture is added with gamma-methacryloxypropyltrimethoxysilane and polyether modified methyl alkyl polyorganosiloxane, and then is mixed evenly; the mixture is added with 1,250-mesh titanium dioxide, 800-mesh precipitated barium sulfate, 800-mesh grey ferro titanium powder, 1,250-mesh gas-phase silicon dioxide, 1,250-mesh wollastonite in powder, 2,500-mesh nano-alumina powder and 2,500-mesh molybdenum disulfide, and is stirred and ground into the wear-resistant, high-temperature resistant and anti-corrosion coating for the sand-containing heavy oil gathering pipelines; and after curing, the wear-resistant, high-temperature resistant and anti-corrosion coating forms a wear-resistant, high-temperature resistant and anti-corrosion coat for the sand-containing heavy oil gathering pipelines. The wear-resistant, high-temperature resistant and anti-corrosion coating can be used for corrosion resistance of inner walls of high temperature sand-containing oil gathering pipelines in the development of sand-containing heavy oil fileds.

Description

technical field [0001] The invention relates to a wear-resistant, high-temperature and anti-corrosion paint for a sandy heavy oil gathering and transportation pipeline and a manufacturing method thereof, which are used for anticorrosion of the inner wall of a high temperature crude oil gathering and transportation pipeline in a sandy heavy oil oilfield. Background technique [0002] Some existing heavy oil fields adopt the steam injection huff and puff production method. First, the superheated steam at 270°C to 320°C is used to inject steam to reduce the viscosity of the oil layer, and the wells are allowed to simmer for a certain period of time before mining. In the initial stage of oil production, due to the high temperature of the oil flow and the fact that the oil flow contains a certain amount of gravel or sand powder, under the combined action of high temperature, gravel abrasion and crude oil corrosion components, the abrasion and corrosion of the gathering and transpo...
