Particle impact drilling technology：the state of the art and perspective development
摘要
Abstract
The application of particle impact drilling ( PID) technology in hard and strong abrasive rock formations has a great potential for increasing drilling speed and efficiency. In this paper, the state of the art of the PID technology was de-scribed and its prospective development was analyzed based on an intensive literature survey in the area over the world and the author's active research work. The recent progress of the PID technology and its key aspects were summarized systemati-cally, including the particle injection and recovery systems and tools used for down-hole rock-breaking. Continuous and sta-ble injection of hard and abrasive particles into drilling fluid is essential to the PID application, and the homogenous distribu-tion of the particles in drilling fluid and their recovery on the surface are also important for the efficiency of the technology. Individualized design of the PID bit and optimum selection of the hydraulic paramenters are the key points of the current re-search. Improvement of the service life of the PID system and its stability is fundenmental for the application of the technolo-gy, which needs further research and breakthrough. On the mechanism study of the PID, it has been focused on the effects of dynamic loading and stress wave damage and softening of the particle jet on rocks and the combined jet-mechanical rock breaking mechanism, which are still the research fronts of the future study.关键词
