Abstract: The technology of radial well fracturing combined with steam soak is suitable for the development of heavy oil reservoir with low permeability,but it is lack of mechanism research so far. The fracture morphology of radial well fracturing was studied by 3 D simulating experiment,and the thermal deliverability of radial well was researched by simulation. The results show that multi-cracks morphology is performed under the multi radial wells which could increases the drainage area,and the radial well can guide the fracture of hydraulic fracturing well. The steam soak stimulation assisted by radial well fracturing is very effective for the development of heavy oil reservoir with low permeability,and the productivity gets the best effect when the number of the radial wells is 4. The thermal deliverability in 3 years of radial well fracturing is 2.65 times larger than that of regular fracturing. The applicability of the combined technology was proved and the parameters of steam soak were optimized. The conclusion is significant and important for the development of heavy oil reservoir.
