Abstract: There are a series of problems in the drilling process of ultra deep and ultra long sections of a ten thousand meter deep well, such as severe vibration of the drill string, slow rock breaking drilling speed, and short effective working life of the drill bit. It is urgent to carry out research on vibration reduction and bottomhole energy enhancement technology of the ten thousand meter deep well drill string. Based on the main characteristics of the ten thousand meter ultra deep drilling environment and combined with recent research results on drill string dynamics, a method is proposed to use drill string vibration as an energy source during the drilling process to increase the jet pressure of drilling fluid at the bottom of the well. While reducing drill string vibration to protect the drill bit, the jet pressure of the drill bit is increased to achieve downhole energy enhancement and rock breaking, solving the problems of high vibration intensity and insufficient hydraulic energy at the bottom of the well. A vibration reduction and energy enhancement device for the drill string at the bottom of the well has been developed, and on-site tests have been conducted. The research results indicate that drilling string vibration contains enormous energy, which can be converted into rock breaking and acceleration energy; The designed vibration reduction and energy enhancement device for the bottom hole drill string can increase the jet pressure of drilling fluid, while reducing the safety risks caused by drill string vibration, thereby significantly improving drilling speed. The research results have opened up new directions for the vibration reduction and acceleration technology of ten thousand meter deep wells, and provided equipment support for accelerating the exploration and development of deep oil and gas resources.
