The invention discloses a full-three-dimensional real-time drilling simulation method, comprising the following steps: (1) a three-dimensional drilling solid model bank is built by adopting a three-dimensional animation modeling method; (2) a graphics processor is specially arranged, the graphics processor comprises a graphics drawing program and a scene simulation control program; (3) the scene simulation control program is communicated with an external mast control program according to given data format, so as to obtain the real-time animation commands and data; (4) scene simulation control program sends out an operational instruction to the graphics drawing program, and the graphics drawing program realizes drilling simulation animation drawing and display. In the invention, based on the computer simulation technology, by taking the practical operational flow of the drilling operation filed as reference, the drilling process and the operation method can be simulated vividly, and high-quality graphics animation is generated for the training of technical skills of operating personnel at the drilling site and students, the training effect is improved, the training period is shortened and the training cost is reduced.
