| titleOfInvention | Oil production method using surfactants based on butylene-oxide-containing alkyl alkoxylates |
| abstract | FIELD: oil and gas industry.SUBSTANCE: invention is referred to an oil production method by flooding with the Windsor III microemulsion, wherein at least through one injector an aqueous compound of surfactants is injected to the oil deposit in order to reduce surface tension between oil and water up to values less than 0.1 mN/m, and the above compound includes at least one surfactant, while from the oil deposit raw oil is extracted at least through one producer; the method is featured by the usage of the aqueous compound of surfactants containing at least one surfactant with the general formula of R-O-(D)-(B)-(A)-XYM, where Rstands for a linear or branched saturated or unsaturated aliphatic and/or aromatic residue with the number of carbon atoms from eight up to thirty, A stands for an ethylene oxide group, B stands for a propylene oxide group and D stands for a butylene oxide group, l stands for a number from 0 up to 99, m stands for a number from 0 up to 99 and n stands for a number from 1 up to 99, X stands for an alkyl or alkylene group with the number of carbon atoms from 0 up to 10, Mstands for a cation and Yis selected from the following groups: sulphate groups, sulphonate groups, carboxylate groups and phosphate groups, at that A, B and D groups may have statistic or alternate distribution or they may be present as two, three, four or several units in any sequence, the amount of l+m+n lies within limits from 3 up to 99 and contents of 1,2-butylene oxide groups on the basis of the whole quantity of the butylene oxide groups is not less than 80%.EFFECT: this substance features special efficiency when it is used at flooding with surfactants.7 cl, 7 tbl |
