Embodiment Construction

[0008] A low-toxic lubricating oil emulsifier, which is composed of the following raw materials in parts by weight: 2-5 parts of sorbitan trioleate, 0.3-0.5 parts of nonylphenol polyoxyethylene ether, 0.3-0.8 parts of triethanolamine, oil 1~3 parts of acid, 3~6 parts of calcium heavy alkylbenzene sulfonate, of which, 3 parts of sorbitan trioleate, 0.35 parts of nonylphenol polyoxyethylene ether, 0.5 parts of triethanolamine, 2 parts of oleic acid , 5 parts of heavy alkylbenzene sulfonate calcium.

[0009] The viscosity reducer prepared with this ratio has strong activity and low surface tension, and has good washing and viscosity reduction effects on paraffin, colloid and asphalt, and can achieve the purpose of reducing the viscosity of the oil layer and increasing the recovery factor of the oil reservoir.

Abstract

The invention relates to the technical field of surfactants, and especially relates to a low-toxicity lubricating oil emulsifier. The emulsifier comprises, by weight, 2-5 parts of sorbitan trioleate,0.3-0.5 part of nonylphenol polyoxyethylene ether, 0.3-0.8 part of triethanolamine, 1-3 parts of oleic acid and 3-6 parts of calcium heavy alkylbenzene sulfonate, and further comprises, by weight, 3 parts of sorbitan trioleate, 0.35 part of nonylphenol polyoxyethylene ether, 0.5 part of triethanolamine, 2 parts of oleic acid and 5 parts of calcium heavy alkylbenzene sulfonate. A viscosity reducerprepared according to the above ratio has the advantages of strong activity and low surface tension, has good washing and viscosity-reducing effects on paraffin, colloids and asphalt, and can achievethe purposes of reducing the oil layer viscosity and improving the recovery rate of oil reservoirs.

Description

technical field [0001] The invention relates to the technical field of surfactants, in particular to a low-toxicity lubricating oil 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 low toxicity lubricating oil emulsifi...
