我国研制和使用液动冲击回转钻进技术是五十年代末开始的,目前已有十多个单位从事这项研究工作。研制成各种冲击器廿余种。射流式冲击回转钻具(又称射流式冲击器)目前已成系列产品,经10万余米进尺证明,该钻具结构简单。易于操作和维修。在各种不同岩石中使用硬质合金钻头可比单纯回转钻进提
The development and application of hydraulic impact rotary drilling technology in China began in the late 1950s, and more than 10 units have been engaged in this research. Developed into a variety of impactors more than 20 species. Jet impact rotary drilling tools (also known as jet impactor) has now become a series of products, the footage of 100,000 meters proved that the drill structure is simple. Easy to operate and repair. Carbide drills can be used to drill in a variety of different rocks than simply rotary drills
