1. IntroductionWith the development of oil-gas and geological drilling engineering, drilling engineering is constantly moving towards deep-ground, on the one hand, in order to develop deep-ground oil, gas, geothermal, and mineral resources [1], and on the other hand, to promote the development of geoscience [2]. During the process of drilling deep into the ground, drilling engineering faces more and more challenges, such as increasing formation temperature and deteriorating rock drillability.
