英文摘要：

Aimed at the problems of the limited scope and low efficiency of the catalytic aquathermolysis, taking the heavy oil wells in Gudong Oil Production Plant of Shengli Oilfield as the studying objects, the influences of the low-frequency vibration on the diffusing property and viscosity reduction of the multi-activity point catalyst assisted with the low-frequency harmonic vibration wave, and the vibrating parameters are optimized. The effects of the cat- alytic pyrolysis assisted with heat-wave coupling under the experimental conditions of the dynamic and static states, and moreover the pilot tests are conducted. The results show that the low-frequency vibration is helpful for the diffu- sion of the catalyst in the oil, water and porous media. Compared with the pure catalytic pyrolysis, the technique stated above has reduced the threshold temperature of the action and increased the viscosity reduction effect. For 4 wells in the pilot test, after the stimulation, the accumulative incremental oil is up to 2 444 t, and furthermore the steam oil ratio has reached by 28%.
