Embodiment Construction
[0026] Such as figure 1 As shown, in the oil pipe with organic fluorocarbon coating of the present invention, a layer of organic fluorocarbon coating layer 2 is formed on the inner wall 1 of the oil pipe by spraying.
[0027] The organic fluorocarbon coating of the present invention is made of the following components by weight percentage:
[0028] Fluorocarbon resin 50.0%~70.0%
[0029] Dispersant 0.5%~2.0%
[0030] Leveling agent 0.5% ~ 1.5%
[0031] Anti-settling agent 0.2%~1.0%
[0032] Defoamer 1.0%~3.0%
[0033] Plasticizer 5.0%~10.0%
[0034] Graphite 10.0%~20.0%
[0035] Carbon black 0.5%~1.0%
[0036] Organic titanium chelate 0.2%~0.5%
[0037] Mixed solvent 5.0%~10.0%
[0038] Curing agent 1.0%~2.0%
[0039] Among them, the fluorocarbon resin is polytetrafluoroethylene resin, the dispersant is BYK-161 dispersant, the leveling agent is BYK-354 acrylic leveling agent, the anti-settling agent is BYK-410 anti-settling agent, and the defoaming agent is BYK -141...

The invention discloses an oil pipe with an organic fluorocarbon coating and an organic fluorocarbon coating. The oil pipe has the organic fluorocarbon coating spray-coated on the inner wall of the oil pipe. The organic fluorocarbon coating comprises, by weight, 50.0-70.0% of fluorocarbon resin, 0.5-2.0% of a dispersant, 0.5-1.5% of a flatting agent, 0.2-1.0% of an anti-settling agent, 1.0-3.0% of a defoaming agent, 5.0-10.0% of a plasticizer, 10.0-20.0% of graphite, 0.5-1.0% of carbon black, 0.2-0.5% of an organic titanium chelate, 5.0-10.0% of a mixed solvent and 1.0-2.0% of a curing agent. The organic fluorocarbon coating spray-coated on the inner wall of the oil pipe can satisfy service conditions of an air-based oil-displacement pipe in a wear and corrosion environment and is suitable for being used for an air-based oil-displacement pipe and a petroleum conveying pipe in an oil field.
Description
technical field [0001] The invention relates to an oil field air drive injection-production well oil pipe internal protection technology, in particular to an oil pipe with an organic fluorocarbon coating and the organic fluorocarbon coating. Background technique [0002] Air flooding for enhanced oil recovery is an effective new technology for enhanced oil recovery, but corrosion is the bottleneck that restricts the popularization and application of this technology. O in the air 2 Consumed by oxidation reaction with reservoir crude oil, a small amount of CO is generated 2 and CO with N 2 Form flue gas to realize oil displacement. The source of air is not restricted by region and space, the gas source is abundant and the cost is cheap, so the air injection mining technology has broad prospects. However, in the actual production process, gas injection wells, oil production wells and ground equipment are in a very complex corrosion environment. Especially downhole, because...
