The present invention is related to the obtaining and use of zwitterionic geminal liquids based on hydroxypropyl betaine, as wettability modifiers of rocks such as limestone, dolomite, sandstone, quartz or heterogeneous lithologies, in the presence of brines with high content of divalent ions as calcium, magnesium, barium and strontium, at high temperature and high pressure conditions during the application of enhanced oil recovery processes. The zwitterionic geminal liquids based hydroxypropyl betaine of the present invention have also the property of acting as inhibitors/dispersing of asphaltenes, both at extraction and production operations of petroleum industry, thus allowing to increase the level of crude oil production. An additional advantage presented by zwitterionic geminal liquid based on hydroxypropyl betaine which can be dissolved in distilled water, brine, aliphatic hydrocarbons or other polar and nonpolar solvents. 本发明涉及基于羟丙基甜菜碱的偕两性离子液体的获得和使用，所述偕两性离子液体在应用强化采油过程中在具有高含量二价离子(诸如钙、镁、钡和锶)的盐水存在下在高温和高压条
