| titleOfInvention | Nano SiO2 composite material thickened oil viscosity reducer and preparation method thereof |
| abstract | The invention discloses a nano SiO2 composite material thickened oil viscosity reducer and a preparation method thereof, which belongs to the technical field of nano SiO2 composite material preparation and application thereof. The viscosity reducer is nano (polymethacrylate higher alcohol-acrylamide)/SiO2 composite material. The preparation method comprises the following steps: 1)pre-modifying the surface of the nano SiO2 by a silane coupling agent; and 2)performing graft copolymerization of (methyl)acrylate higher alcohol and acrylamide on the surface of nano SiO2 to obtain the (polymethacrylate higher alcohol-acrylamide)/SiO2 composite material powder. The nano viscosity reducer has the advantages of good viscosity reducing effect, low cost, simple production and no pollution during a cleaning process. Through the experiment, the viscosity reducing rate of the nano viscosity reducer to the high wax thickened oil at Daqing dandong station is 72.10% at 40 DEG C. |
