Was used a cationic surfactant having a hydrophobic block having a chain length of 10 carbon atoms of six, a method for generation of a mineral oil

摘要

The present invention, there is provided a method for generation of a mineral oil with a Winsor type III microemulsion flooding, R ¹ N ⁺ (R ²⁾_m (R ³⁾_n general formula (R ⁴⁾ X ^- in and, poured into mineral oil sediments through the injection hole, the detergent formulation an aqueous containing an ionic surfactant in one, through the output aperture, to a method of extracting from the sediment the crude oil at least.
