摘要
本文介绍了一种三层管压卡式取样钻具,将经过改进的三层管压卡式取样钻具与孔底局部喷射反循环机构相结合,形成了适合钻进硬脆碎地层的取心工具——三层管压卡式喷反取样钻具。
This paper presented a press-fitting sampling drilling tool of three-layer pipes.After an improved press-fitting sampling drilling tool of three-layer pipes was combined with reverse circulation mechanism with local spurt at hole bottom,a press-fitting sampling drilling tool of three three-layer with spurt reverse circulation was producted.
