USE OF TRIS(2-HYDROXYPHENYL)METHANE DERIVATIVES FOR TERTIARY PETROLEUM PRODUCTION |
摘要 |
A process for mineral oil production, in which an aqueous formulation comprising tris(2-hydroxyphenyl)methane of the general formula (I) is injected into a mineral oil deposit through an injection well and the crude oil is withdrawn from the deposit through a production well, where the R1, R2 and R radicals in the formula (I) are each defined as follows: R is independently 1 to 2 hydrocarbyl radicals per phenyl ring, R1 is preferably H or OH, R2 are independently radicals of the general formula (III), —(R5—O—)n—R6—X  (III) where n is a number from 1-50, and where the R5 radicals are R7 groups R6 is a single bond or an alkylene group having 1 to 10 carbon atoms, X is H or an acidic end group, R10 is, for example, C1-C6-hydrocarbyl radical, enables improved mineral oil production. |
