Abstract

Abstract: Heavy oil has the characteristic of high viscosity, and with the increase of water cut, the viscosity of water-in-oil emulsion will increase further. To reduce the viscosity and improve its transportation capacity, the method of viscosity reduction by synergistic action of nano-catalyst and microwave is proposed. The response surface method is selected as the experimental design method and the influence factors include microwave heat power, temperature and nano-catalyst concentration. The viscosity-temperature curves under different experimental conditions are measured to calculate the viscosity reduction rate, to obtain the optimal viscosity reduction treatment method under different water cuts. The interaction between three factors and the influence of the change of water cut on the synergistic action on viscosity are explored. The experimental result shows that at the same water cut, the viscosity reduction rate increases with the increase of catalyst concentration, and increases first and then decreases with the increase of microwave power, and the variation of viscosity reduction rate with temperature is related to the water cut. In order to achieve the optimal viscosity reduction effect of different water cut, the required catalyst concentration increases first and then decreases. The required microwave power is similar, but the temperature is different. It shows that the viscosity reduction effect of water-in-oil emulsion with high water cut is better, which can provide theoretical basis for heavy oil viscosity reduction technology.
