Product Introduction
This mutual solvent is a small molecule alcohol ether product that has good solubility in both water and oil, and can eliminate residual acid residues. This product has good compatibility with acid solution, which can reduce the adsorption loss of surfactants, make the droplets formed during the acidification process easy to merge, prevent oil-water emulsification, accelerate backflow, maintain the water wettability of rocks, reduce the flow resistance of oil under the same permeability after acidification, and prevent stable emulsification of solid particles in the formation, which is conducive to preventing formation damage, improving the efficiency of acidification working fluid, and achieving the goal of increasing production.

Application
This series of products is mainly used in acidizing fluids for oil and water wells, making it easy for the droplets formed during the acidizing process to merge, preventing emulsification of oil and water, accelerating backflow, maintaining the water wettability of rocks, and preventing stable emulsification of solid particles in the formation, which is beneficial for preventing formation damage and improving the efficiency of acidizing working fluids. During operation, this product can be directly added to the acidizing fluid and mixed well.
