In the process of crude oil exploitation，due to the influence of temperature，pressure，oil phase composition variety and external fluid，the phase equilibrium state of crude oil colloid system is easy to be destroyed，resulting in continuous association and deposition of asphaltene，which brings great difficulties to crude oil extraction and post-treatment. The evaluation methods of asphaltene deposition in crude oil are reviewed，including drop diffusion method，viscosity method，optical method，conductivity method，micro analysis method，displacement experiment method and thermodynamics method. The existing problems and development trend of evaluation methods are analyzed. A universal evaluation method which can reflect the asphaltene deposition process under reservoir conditions is urgently needed. It can predict the possibility of asphaltene deposition in crude oil，and optimize the inhibition technology and unplugging technology.
