METHOD FOR PREPARING HIGH-TEMPERATURE RESISTANT OIL-BASED DRILLING FLUID WETTING AGENT

摘要

A method for preparing a high-temperature resistant oil-based drilling fluid wetting agent. A drilling fluid wetting agent is prepared according to the following steps: a first step: preparing fatty acid esters; and a second step: preparing a drilling fluid wetting agent finished product. A drilling fluid wetting agent prepared by the method for preparing a high-temperature resistant oil-based drilling fluid wetting agent can improve the high-temperature emulsification stability of an oil-based drilling fluid system and the oil wetting performance of hydrophilic components, thereby promoting the stability of the drilling fluid system.
