Abstract

The invention discloses a water-based antiwax remover and a preparation method thereof. The water-based antiwax remover consists of a wax melting dispersant, a reverse wetting agent, a solubilizationdispersant, an alcohol cosolvent and water or simulated salty water, wherein the wax melting dispersant, the reverse wetting agent, the solubilization dispersant and the alcohol cosolvent account for15-35% of the water-based antiwax remover. The preparation method of the water-based antiwax remover comprises the following steps: uniformly mixing the wax melting dispersant, the reverse wetting agent and the solubilization dispersant, adding the alcohol cosolvent, mixing, and adding the water or the simulated salty water, thereby obtaining the water-based antiwax remover. The invention relatesto the water-based antiwax remover and the preparation method thereof, the water-based antiwax remover is capable of both preventing and cleaning wax, and compared with a conventional emulsion-type antiwax remover, the water-based antiwax remover is relatively safe, efficient, odorless, free of pollution and high in flash point.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploration, collection and transportation, and in particular relates to a water-based wax remover and a preparation method thereof. Background technique [0002] Most of the crude oil mined in my country contains a certain amount of wax. The wax in the crude oil in the formation usually exists in a dissolved state. However, during the extraction of crude oil, the crude oil produced by the oil well is mined from the underground and transported to the ground. , the temperature and pressure of the crude oil liquid continue to drop, and the ability of the crude oil to dissolve wax gradually decreases. When the temperature of the crude oil liquid is lower than the melting point of the wax in it, the wax begins to crystallize gradually, and the precipitated wax will deposit around the well wall and produce In the casing, it will cause damage to the reservoir, cause problems such as sucker rod overload,...
