METHOD FOR PRODUCING CRUDE OIL USING CATIONIC SURFACTANTS COMPRISING A HYDROPHOBIC BLOCK HAVING A CHAIN LENGTH OF 6 - 10 CARBON ATOMS. |
| 摘要 |
<p>The invention relates to a method for producing crude oil by means of Winsor type III microemulsion flooding, wherein an aqueous surfactant formulation which comprises at least one ionic surfactant of general formula R1 N+ (R2)m (R3)n (R4) X- is forced through injection wells into a mineral oil deposit and crude oil is withdrawn from the deposit through production wells.</p> |
