摘要： The invention relates to the use of at least one compound corresponding to the following formula: R—O—(—CH2-CH(CH3)-O-)m-(—CH2-CH2-0-)u-H where: R is a hydrocarbon-based group comprising from 6 to 40 carbons; m ranges from 0 to 20; n, which is greater than m, ranges from 5 to 40, in order to inhibit the phenomena of retention of anionic surfactants within an oil-bearing reservoir, in particular within a carbonate or clay reservoir.

摘要： The inhibition of anionic surfactant retention phenomena in an oil reservoir, especially in a carbonate-based or argillaceous reservoir, by the use of at least one compound corresponding to the formula R—O-(A)m-H, in which R is a hydrocarbon-based group comprising from 6 to 40 carbon atoms, A is a hexose or pentose unit, and m is a non-zero number ranging from 1 to 10, is described herein.
