Abstract: An oil-soluble nanocomposite viscosity reducer (NVR) for crude oil is synthesized with organic modified nanosilica,octadecyl methacrylate,acrylamide and styrene as raw materials.Its structure and morphology are characterized by IR and SEM.Under 60℃,the viscosity reduction effect of NVR prepared by different silica dosages,synthesis reaction time and temperature is investigated.The usage of NVR in Karamay crude oil is studied.It is shown that the prepared NVR has obvious viscosity-reducing effect on Karamay crude oil.If the NVR product prepared under the optimum formulation is used,it can result in an apparent viscosity reduction rate of over 91% and a net viscosity reduction rate of over 32% for Karamay crude oil.
