The invention discloses a method for solving anti-drilling characteristic parameters based on logging while drilling data. The method mainly solves the problems that an existing method for obtaining stratum anti-drilling characteristic parameters is few in data and large in error, and the drilling period is prolonged. The method is characterized by comprising the following steps: measuring the hardness, the plasticity coefficient, the drillability grade value and the mechanical specific energy value of the rock, and fitting a relation model of the mechanical specific energy, the hardness, the plasticity coefficient and the drillability grade value according to a measurement result; logging engineering data are collected on site, and bit pressure and torque are corrected; correcting the mechanical specific energy value, and calculating standardized mechanical specific energy according to the corrected mechanical specific energy; logging engineering data are collected on site, a standardized mechanical specific
