Such thesis, from the micro perspective, obtains bubble quantity and their distribution in oil phase under different pressures by means of establishing formation and growth model of the bubble in foam oil so as to form property model of foam oil and then constitute inflow performance model of foam oil occurring in cold production for heavy oil reservoirs via modifying inflow performance relationship for conventional crude oil so as to use for output forecast of foam oil production well in cold production for heavy oil. The research indicates that the formation and growth of bubbles occurring in cold production for heavy oil reservoirs have critical influence on the property of foam oil and also affect its development trend; the model calculation reveals that IPR curve of foam oil in cold production for heavy oil reservoirs , significantly different from that calculated upon conventional model, is in adverse trend and in line with the development characteristics of foam oil; the IPR curve upon theoretical model is consistent with that upon CMG-STARS model in tendency, but there is still some difference for the bubble broken is not considered in theoretical model. Consequently, the curve upon theoretical model has obvious down jog and the error occurs to some extent so that the model shall be modified further.
Key words: Bubble growth, bubble quantity, foam oil, IPR curve, micro-bubble, ,
