With the development of rock bits and drilling technology, turbodrills have been successfully applied in combination with new types of diamond bits and high speed roller bits, as well as in the special fields including directional drilling, horizontal drilling and high angle borehole drilling. Requirements of various rock bits and drilling technology can be met by improving the performance and structure of turbodrills to increase their working life. Developing turbodrilling technology in China should be focused on the development of turbodrills with low pressure and high torque output to serve the various purposes for drilling, and increase the working life of turbodrill, and improve drilling conditions, and optimizing drilling program.
