| titleOfInvention | Emulsifier for invert emulsion to increase oil recovery of formations |
| abstract | FIELD: oil, gas and coke-chemical industries.SUBSTANCE: invention relates to oil industry and can be used in production of emulsifier of invert emulsions for increasing oil recovery of formations. Emulsifier of invert emulsion for increasing oil recovery of formations, containing oil-soluble surfactant - OSS, oleic acid and a hydrocarbon solvent, additionally contains cocamidopropyldimethylamine or oleylamidopropyldimethylamine, and the OSS contains a Stenore - a mixture of ethoxylated, propoxylated C12-C15 fraction alcohols, or Sintanor - ethoxylates of fatty alcohols, or Synthanol - a mixture of primary oxyethylated synthetic higher fatty alcohols C12-C14, and as hydrocarbon solvent - furnace or diesel fuel at following ratio of components, wt. %: Stenore, or Sintanor, or Synthanol 5–10, oleic acid 5–15, cocamidopropyldimethylamine or oleylamidopropyldimethylamine 5–15, furnace or diesel fuel is the rest, wherein the weight ratio of oleic acid to cocamidopropyldimethylamine or oleylamidopropyldimethylamine ranges from 1:1.5 to 1.5:1.EFFECT: technical result is higher efficiency of emulsifier.1 cl, 1 tbl, 1 ex |
