Development and performance evaluation of catalyst for viscosity-reduction of heavy oil

utilize the heavy oil reservoirs by further reducing the viscosity of heavy oil. Based on the analysis of heavy oil properties in Shengli Oilfield, the technology of catalytic viscosity-reduction was developed, and the effect of technology was evaluated under laboratory conditions. By using this technology, the viscosity of heavy oil decreased by 65.0% under the conditions of 1.5% catalyst dosage, reaction temperature of 200 ℃ and reaction time of 20 h.
