The surfactant contains as an essential component an internal olefin sulfonate having 10 to 26 carbon atoms, a hydroxyalkane sulfonate content of not less than about 40% by weight and a disulfonate content of not more than 20% by weight and said internal olefin sulfonate being desired from the sulfonation of an internal olefin having the general formula:R--CH.dbd.CH--R'wherein R is a straight- or branched-chain alkyl group having 4 to 23 carbon atoms, R' is a straight- or branched-chain alkyl group having 1 to 12 carbon atoms provided that the total carbon atom numbers of R and R' is 8 to 24 and 50% by weight or more of the internal olefins is that having R' with 1 to 4 carbon atoms. This micellar slug has an excellent capability for decreasing an interfacial tension between oil and water and an excellent salinity tolerance and hard-water resistance. Furthermore, the micro-emulsion can be formed from this micellar slug in a wide composition range.

摘要： A micellar slug for use in the recovery of oil is described, the slug containing a hydrocarbon, an aqueous medium, a surfactant, and a cosurfactant. The surfactant contains, as an essential component, a divalent metal salt of an alpha-olefin sulfonic acid. This micellar slug has an excellent salinity tolerance and hard-water resistance. Furthermore, the micro-emulsion formed from the present micellar slug is maintained stable in a subterranean reservoir formed by alkaline earth metal carbonates and, therefore, the oil recovery efficiency can be improved.
