Abstract: In order to study in-situ modification and viscosity reduction technology of solid heavy oil and improve oil recovery,the most critical factor catalyst was studied. Iron naphthenate,an oil-soluble catalyst,and ferric nitrate,a water-soluble catalyst,were employed,and their separate and combined effects on viscosity reduction were evaluated. The results showed that,the viscosity of heavy oil was reduced by 56.29% and 45.40% respectively when the two were used as separate catalyst,while the viscosity was significantly reduced by 97% when the two catalysts were combined. The distributed activation energy model (DAEM) was employed to analyze the pyrolysis process of heavy oil and the synergistic effect of the catalysts helps to integrate the advantages of the two catalysts.

Keywords: heavy oil; viscosity reduction; combined catalyst; distributed activation energy model; dynamics
