Under the condition of cyclic steam stimulation, the upgrading laboratory experiments and field testing involving addition of catalyst and/or hydrogen donor were carried out for the extra-heavy oil in Shuguang Region in Liaohe Oilfield. It was found that the extra-heavy oil was upgraded using catalyst or/and hydrogen donor, the contents of asphaltene, resin and sulphur were decreased, at the same time, the mole ratio of H and C and the contents of saturated and aromatic hydrocarbon increased respectively. As a result, the viscosity of the heavy oil was decreased greatly. Catalyst and hydrogen donor had synergetic effect on the upgrading reactions, with the addition of catalyst and tetralin 87% deduction in the viscosity was observed, catalyst and hydrogen donor developed the deduction in viscosity is 80%. It could be proved that the production of heavy oil and water of the wells were increased greatly after in-situ upgrading treated using catalyst and hydrogen donor during the steam injection, both the decrease in viscosity and increase in oil production were significant.
