It is the foamy oil which was seemed as the main factor leading the unexpected high production and high recovery of some heavy oil reservoirs in Canada and Venezuela. When it comes to the issue of foamy oil viscosity,there are disputes about whether the viscosity is higher or not than that of the initial live oil. In order to get a better understanding of the issue, this paper carried out detailed investigation about the foamy oil viscosity on three aspects：the relationship between the viscosity and the unexpected high production, the viscosity model of foamy oil and the influencing factors of foamy oil viscosity. It is considered that the influencing factors of the foamy oil viscosity include the pressure depletion rate, stabilization time, measuring device, dispersed gas volume fraction, pressure and flow rate, expansion ratio, surfactant, the size of dispersed bubble, the shearing rate and the conventional or unconventional testing method, and the controversy of the foamy oil viscosity is relevant to these influencing factors,and it is mainly caused by the measuring of the viscosity. Furthermore, the seepage mechanism of foamy oil has important significance for heavy oil reservoir numerical simulation and the optimization design of gas injection for heavy oil reservoir.
