[0002] Geological survey is a geological investigation and research work carried out to identify the geological factors that affect engineering buildings. The geological factors that need to be surveyed include geological structure, landform, hydrogeological conditions, physical and mechanical properties of soil and rock. Drilling equipment is required when surveying geological structure.

[0003] The drill bit is the main tool for breaking rocks during the drilling process. The wellbore is formed by the drill bit breaking rocks. The quality of a wellbore and the length of time it takes to form it are related not only to the characteristics of the rock formation being drilled and the performance of the drill bit itself, but also to the degree of mutual matching between the drill bit and the formation. The reasonable selection of the drill bit plays an important role in increasing the drilling speed and reducing the overall drilling cost.
