METHOD FOR PRODUCING MINERAL OIL USING SURFACTANTS BASED ON A MIXTURE OF C24-GUERBET-, C26-GUERBET-, C28-GUERBET-CONTAINING HYDROCARBON ALKOXYLATES |
摘要 |
<p>The invention relates to a surfactant mixture containing, in relation to the hydrocarbon part (R1)(R2)-CH-CH2- at least three different ionic surfactants of general formula (I), wherein R1, R2, A0, k, X, o, Y, a, b, M have the meaning indicated in the description and the claims. The invention further relates to the use and production thereof and to aqueous surfactant formulations containing the mixtures and to a method for producing mineral oil by means of Winsor type III micro emulsion flooding, in which the aqueous surfactant formulation is forced through injection wells into a mineral oil deposit and the crude oil is removed from the deposit through production wells.</p> |
