Abstract
Disclosed are a rock drilling experimental device and a method for simulating true triaxial conditions of deep well drilling; the device includes an energy supply module, an experimental loading module, a hydraulic supply module, a parameter control module and a data acquisition module. The device provides power through the energy supply module; the experimental loading module applies three directional stresses, a liquid column pressure and a pore pressure to a rock specimen by simulating a formation environment, and simultaneously drills into the rock specimen with a bit; the hydraulic supply module provides a hydraulic pressure to the liquid column pressure, the pore pressure and the three directional stresses in the experimental loading device; and the parameter control module is used to control a displacement module of the experimental loading module to move, and adjust a displacement, the pressure and a temperature to the target values.
