Based on the analysis of the existing light oil blending evaluation method, a new viscosity simulation and evaluation method of heavy oil production assisted with light oil blending was established to study the flowing dynamic and viscosity changes of the mixed oil system in wellbore. And the influences of blending ratio, blending temperature and diluents type were evaluated. The results show that the relative error of evaluation method is less than 5.36% when the fluid viscosity is no more than 74 mPa∙s, which means this evaluation method has good stability and reliability for heavy oil viscosity measurement and analysis. The mixed and viscosity reduction evolves with the wellbore flowing. And improving the blending temperature and injection diluted thinners are beneficial to improve the effect, which can provide a powerful reference for practical production for optimization design.
