Abstract

The invention relates to the technical field of surfactants, in particular to a high-energy oil demulsifying agent which is prepared from the following raw materials in parts by weight: 60-80 parts ofpapermaking black liquor resin, 25-35 parts of fatty acid sodium, 12-16 parts of fatty alcohol-polyethylene oxide ether sulfate, 12-15 parts of sodium hydroxide and 70-85 parts of water, the viscosity reducer prepared by the ratio of 70 parts of the papermaking black liquor resin, 30 parts of the fatty acid sodium, 15 parts of the fatty alcohol-polyethylene oxide ether sulfate, 13 parts of the sodium hydroxide and 75 parts of the water is high in activity, low in surface tension and relatively good in washing and viscosity reduction effects on paraffin, colloid and asphalt; the aims of reducing the viscosity of the oil layer and improving the oil reservoir recovery rate can be achieved.

Description

technical field [0001] The invention relates to the technical field of surfactants, in particular to a high-energy oil anti-emulsifier. Background technique [0002] Emulsifier is a substance that can improve the surface tension between the various constituent phases in the emulsion to form a uniform and stable dispersion system or emulsion. Emulsifier is a surface active substance with both hydrophilic and lipophilic groups in the molecule. The base, which gathers on the oil / water interface, can reduce the interfacial tension and reduce the energy required to form the emulsion, thereby increasing the energy of the emulsion. [0003] The existing viscosity reducers used for oil well emulsification have poor activity and poor viscosity reduction effect, which cannot meet the growing demand for use. Contents of the invention [0004] In order to overcome the existing above-mentioned deficiencies, the present invention provides a high-energy oil anti-emulsifier. [0005] Th...
