| Ò»ÏÂÊÇÕªÒª²¿·Ö£ºA new tuning method is proposed for the cubic equation-of-state-based friction theory viscosity model,which improves the viscosity prediction of heavy oils.With the existing tuningmethod, the error in viscosityprediction increases with increasing viscosity. Particularly, at pressures below the saturation pressure, theerror keeps increasing as the pressure is farther away fromthe saturation pressure. With the proposed tuningmethod,whereas the single-phase error is almost the same, the two-phase error is approximately 1/3 the valueof the error from the existing tuning method. Most importantly, the proposed tuning method successfullyuses experimental viscosity data below the saturation pressure to reduce prediction errors. |
