摘要： The present invention relates to the application of geminals zwitterionics liquids based on bis-N-alkyl or bis-N-alkenyl or N-cycloalkyl or N-aryl bis-beta aminoacids or its salts thereof as wettability modifiers of rocks such as limestone, dolomite, sand, quartz or heterogeneous lithologies, in the presence of brines with high content of divalent ions such as calcium, magnesium, barium and strontium, high temperature and pressure in processes of enhanced oil recovery. Wettability modifier comprises a geminal zwitterionic liquid based on bis-N-alkyl or bis-N-alkenyl or N-cycloalkyl or N-aryl bis-beta aminoacids or its salts, using as solvent distilled or brine with a high content of divalent ions such as calcium and magnesium or organic solvents compounds derived from alcohols like methanol, ethanol, isopropanol or mixtures thereof, or aromatic as isomers of xylene, toluene, or diesel, gasoline or mixtures thereof.
Geminals zwitterionics liquids based on bis-N-alkyl or bis-N-alkenyl or N-cycloalkyl or N-aryl bis-beta aminoacids or its salts are obtained by reacting an alkyl or alkenyl amine and an reactive polyether derivative of ethylene or propylene oxide or copolymer of these, which may contain in their structure mesyl or tosyl groups, and subsequently the reaction product is reacted with unsaturated acids such as acrylic acid or methacrylic acid and subsequently may or may not be neutralized with alkali metal bases such as the sodium or potassium hydroxide, carbonates or bicarbonates of potassium or sodium.
