Abstract:With the deep and ultra-deep development of resource exploration, as well as the higher demand for emergency drilling and rescue level guarantee capabilities, rotary percussion drilling technology has become a research hotspot in the field of efficient drilling. Compared with traditional rotary drilling technology, rotary drilling technology has advantages such as high drilling efficiency, low dril-ling pressure, and low stick-slip vibration intensity in hard rock formations. It is widely used in the exploration and exploitation of deep-sea resources, emergency drilling rescue and other fields. At pre-sent, under complex rock formations and variable working conditions, further improving the efficiency of rotary percussion drilling and reducing the costs have become the primary tasks faced in the process of deep and ultra-deep drilling. Firstly, the basic concept and advantages of rotary drilling technology are introduced. Secondly, the development and structural characteristics of hydraulic and pneumatic impactors are reviewed. Thirdly, the research progress and optimization strategies of efficient rock breaking mechanisms are discussed. Fourthly, the research results on key influencing factors of drilling efficiency are elaborated. Finally, based on the research achievements and challenges faced by rotary percussion drilling technology, the future research directions are analyzed and prospected.
