| Abstract:With the characters of high temperature resistance and high rotation speed, turbodrill plays an important role in the process of high temperature and hardpan layers drilling and has become one of the research hotspots in the areas of hot dry rock (HDR) and high temperature oil and gas well drilling. Starting from the development history of turbodrill, the article systematically summarizes the specialties of turbodrill. The researches progress of turbodrill both in China and abroad are overviewed in stucture improvement, design and processing of blades, performance improvement for the bearing supporting, research and development of the deceleration turbodrill and exploration of advanced drilling techniques. According to some problems found in the research on trurbodrill and combining with the actual demands in related fields in China, main researching focuses of turbodrill in the future are proposed. |
