JD直连式深孔绳索取心钻杆的研制与应用

Development and Application of JD Direct-connected Wire-Line Coring Drill Pipe/

根据深部找矿的需要,立足于我国目前钻探设备现状和材料冶炼及机械加工水平,通过对钻杆选材、结构、制造工艺的创新,研制了一种两端镦粗后整体热处理再车螺纹的新型深孔绳索取心钻杆及配套钻具,经使用,效果达到了设计要求。

In the need of deep ore exploration, with current development of drilling equipment, and with smelting and mechanical processing ability, a new wire-line coring drill pipe and its drilling system were developed. The application result met the design requirement.
