The invention relates to a method for preparing poly-alpha-olefin synthetic oil with a high viscosity index. The method comprises the following steps: adding an oligomerization catalyst into raw materials, and carrying out a reaction for 30 to 120 minutes at the temperature of 20 DEG C to 50 DEG C; and separating the catalyst, a reaction product and an unreacted alpha-olefin monomer, and subjecting the reaction product to distillation and hydrogenation, thereby obtaining the poly-alpha-olefin synthetic oil which has the kinematic viscosity of greater than 40cSt and the viscosity index of greater than 150 at the temperature of 100 DEG C.
