Critical mass flow rate of mixture fluid of heavy oil and steam passing through a decompression orifice was measured. The critical flow rate was increased with the ratio of oil flow rate to oil-steam flow rate because the density of oil-gas mixture fluid seemed to increase due to existence of liquid oil. Calculations for characteristics of critical mass flow were done using density and sonic velocity of two phase flow of heavy oil and steam estimated by the experimental data. Calculations show good agreement with the experimental results that showed the tendency of density increase accompanying by decrease of gasification rate of heavy oil.
