| Abstract:The wire-line coring hydro-hammer drilling technology is widely applied for its advantages of effective drilling, largely increased round footage, prolonged bit service life, less auxiliary time and so on. Aiming at the specific requirements of the deep hole environment for the drilling tools in overall strength, safety, stability, service life, high backpressure adaptability and other aspects, this paper discusses a series of improvement and perfection of the original SYZX drilling tools. The production test proves that the improved drilling tools can fully meet the higher requirements for deep drilling construction. |
