【Abstract】 With the development of social economy and industry,the consumption of energy resources has grown continuously, and the demand of oil and gas resources has increased by years.Unconventional oil and gas resources have shown great potential for application,such as heavy crude oil. The key for enhancing the heavy oil recovery is to reduce the viscosity and improve the fluidity,therefore the viscosity reduction technology of heavy crude oil has received more and more attention.The viscosity reduction mechanism and development direction of the heavy crude oil were reviewed in this paper,and the advantages and deficiency of the different exploiting technologies were also analyzed in detail.更多还原
