| titleOfInvention | Three using surface activator composition, preparation method and application |
| abstract | The present invention relates to three using surface activator composition, preparation method and application, it is poor mainly to solve existing surfactant oil displacement efficiency during tertiary oil recovery, simultaneously because oil displacement system contains inorganic base, injury, etching apparatus and pipeline are brought to stratum and oil well and is demulsified the problems such as difficult.The present invention uses surface activator composition by using three, including cationic surfactant and anion nonionic surfactant, the mol ratio of described cationic surfactant and anion nonionic surfactant is 1: 0.01~1: 100, its cationic surfactant is selected from least one of quaternary ammonium salt or quaternary amine alkali, anion nonionic surfactant general molecular formula is shown below, wherein M and N are independently selected from alkali metal, the technical scheme of any one in alkaline-earth metal or ammonium root preferably solves the problem, during tertiary oil production in oil field. |
