地质钻探液动冲击回转钻进技术再(新)认识

New Understanding of Hydraulic Percussive-rotary Drilling Technology in Geological Drilling

针对地质钻探液动冲击回转钻进适用条件、钻探设备配置要求、冲洗液与现场维护、相关新产品研发等方面提出了一些认识和建议。文章认为,当前地质钻探装备条件的改善,冲洗液性能、质量和固相控制(净化)工作的强化,有利地支撑了液动冲击回转钻进技术的推广应用,小直径金刚石绳索取心液动冲击回转钻进已经成为应用最为广泛的液动冲击回转钻进工艺。对原地质矿产标准《液动冲击回转钻探技术规程》(DZ/T 0053—93)进行修订,是推动目前我国液动冲击回转钻进技术发展的举措之一。今后,还应加强新型高能液动潜孔锤研发和示范应用,研究优化大直径、全面钻进工艺。

Some ideas and suggestions are put forward according to the suitable conditions of hydro-percussive rotary drilling technology in geological drilling, drilling equipment configuration requirements, drilling fluid and field maintenance and new products development. It is believed that the current improvement of geological equipments and the strengthening of flushing fluid performance, quality and solid phase control （purification） are favorable to promote the application of hydro-percussive rotary drilling technology, small-diameter diamond wire-line core hydro-percussive rotary drilling technology has become the most widely used hydro-percussive rotary drilling technology. At the present , the revision of original geological and mineral standards “The regulations of hydro-percussive rotary drilling technology（DZ/T 0053—93）” is one of the good methods to promote the development of hydro-percussive rotary drilling technology in China. In the future, it is also necessary to strengthen the development and demonstration application of new type of high-energy hydro-hammer and attach great importance to the optimization of large diameter and hydraulic hammer non-coring drilling technology.
