The invention belongs to the technical field of oil exploitation, and particularly relates to an oligomeric quaternary ammonium salt type heavy oil viscosity reducer and a preparation method thereof.The heavy oil viscosity reducer is an ethoxy quaternary ammonium salt type oligomer. A plurality of amphiphilic elements in the molecular structure of the oligomer have a relatively strong synergisticeffect and are arranged more closely on an oil-water interface, so the oligomer has excellent emulsifying capacity. On the other hand, molecules of the oligomer contains a plurality of EO elements which can effectively chelate heavy metal ions in heavy oil and destroy association of metal ions and asphaltene aromatic lamellas so as to destroy asphaltene aggregate structures. A single ethoxy quaternary ammonium salt type oligomeric surfactant provided by the invention can effectively reduce the viscosity of heavy oil with a high heavy metal content, and has a viscosity reduction rate of up to76-95%.
Interfacial response of a novel gemini metallo-surfactant to ionic guest species
Jaggernauth, Gina E.,Fairman, Richard A.
, p. 15 - 18 (2014/03/21)
The surface properties of a novel metallosurfactant with twin dodecyl aza-crown aliphatic tails (L3) were studied by surface pressure isotherms on aqueous subphases of selected Group I and Group II metals. Mean molecular areas of the headgroup at the mono
