Abstract
The invention provides a preparation method of a high-temperature-resistant drilling fluid filtrate reducer. At normal temperature, a glycan type drilling fluid treatment agent and water are mixed in a reaction container, then sodium benzoate and hexamethylenetetramine are added into the reaction container, a plant polyphenol type material is added to mixed liquid in the reaction container, and finally the mixture in the reaction container is dried in a vacuum mode and smashed to obtain a drilling fluid additive suitable for a high-temperature well; in application, the drilling fluid treatment agent is directly added to water or water-base mud and can be used after being evenly stirred; due to the fact that the plant polyphenol type material is adopted as the additive of the glycan type drilling fluid treatment agent, the structure of glycan can be stabilized by acting force among hydrogen bonds and other molecules, the additive is not prone to degradation or decomposition when used at high temperature, and the temperature resistance can be improved to 150 DEG C or above.
