Abstract

The invention discloses a polyvinyl triazole compound and a preparation method thereof.An acetone solution of hydroxyethyl acrylate is added into a reactor, the pH value is adjusted to be 3-6, then, epoxy chloropropane is added into the reactor drop by drop, and a reaction is performed to obtain 1-chloro-3-hydroxy-butyl-acrylic acid ethyl ether; a DMF solution of the 1-chloro-3-hydroxy-butyl-acrylic acid ethyl ether is dropped into a reaction system containing 1,2,4-triazole and inorganic base, a thermostatic reaction is performed at the temperature 60-90 DEG C for 7-10 h, deionized water, an initiator, a chain transfer agent and a chelating agent are added, and the reaction is performed for 2-5 h.The corrosion inhibitor is corrosion inhibitor molecules by adopting N and O atoms as active centers, and lone pair electrons on heteroatoms can be complex with metal ions in a coordination bond mode to form a polymer and can be combined with metal ions so as to cover the surface of equipment in the mode of an adsorption membrane to achieve corrosion inhibition.

Description

technical field

[0001] The invention belongs to the field of fine chemicals and relates to an oilfield chemical, in particular to a polyvinyltriazole compound and a preparation method thereof. Background technique

[0002] With the development of oil drilling technology and the advancement of oil recovery technology, a large number of deep wells, ultra-deep wells and extremely deep wells have been put into development, which makes oil collection more difficult. Acidizing is one of the production stimulation measures often used in oil field exploitation. Its principle is to use acid liquid to dissolve and dissolve rock cement or blockages in formation voids and cracks; however, the process of injecting acid liquid into formation and collecting oil will Corrosion occurs to varying degrees on surface pipelines and wellbore walls, and sometimes even causes unexpected incidents of equipment pipeline rupture, resulting in huge economic losses and environmental pollution. Therefor...
