Abstract

The invention discloses a spraying method of an oil-gas well segmented fracturing tool. The spraying method comprises the following steps: S1, coating a base layer on a substrate; S2, coating a carbonized anti-permeation layer on the base layer; S3, coating a high-temperature-resistant and high-pressure-resistant anticorrosive coating on the carbonized anti-permeation layer. According to the spraying method of the oil-gas well segmented fracturing tool, the coating with the high-temperature-resistant and high-pressure-resistant performance is formed on the surface of a base material of the oil-gas well segmented fracturing tool, so that the oil-gas well segmented fracturing tool has the performance of high-temperature-resistant and high-pressure-resistant operation, and also has the performance of fast dissolving after the operation is completed, and meets the operation requirement of oil-gas well segmented fracturing.

Description

technical field [0001] The invention relates to the technical field of polymer material spraying, in particular to a spraying method for staged fracturing tools of oil and gas wells. Background technique [0002] Staged fracturing tools for oil and gas wells are usually operated in an environment with high temperature and high pressure. Under such working conditions, materials with high temperature and high pressure resistance are usually used to make staged fracturing tools for oil and gas wells. However, under certain operating conditions, the staged fracturing tools for oil and gas wells need to dissolve quickly after the operation is completed; The staged fracturing tools for oil and gas wells are made of materials with high temperature and high pressure resistance, which cannot meet the requirements of this specific operating condition. If there is a spraying method for oil and gas well staged fracturing tools, a corrosion-resistant coating is formed on the outer surfa...
