Abstract：The conventional technologies of reducing heavy oil viscosity exit the shortages of affecting the quality of crude oil, heavy workload, high cost and other defects. Therefore, new method of heavy oil viscosity reduction based on hydrocarbondegrading bacteria was discussed. A hydrocarbondegrading bacterium was isolated in the laboratory. Its growth curve and its function of reducing viscosity and wax in heavy oil were studied. The results showed that the reduction rate of crude oil ranged from 22.49% to 32.93% and wax precipitation point decreased from the 44.4 ℃ to 39.5 ℃. The same as wax content dropped from 13.00% to 3.80%. The resin content dropped from 16.45% to 13.75%. After adding D1 strain, wax removal rate was 70.08% and wax precipitation point fell 4.9 ℃. The strain had a significant effect on reducing the viscosity of heavy oil and wax content.
