| 摘 要： | 在分析各国整体切削具不提钻可换式钻头结构及存在主要问题的基础上，提出采用整体旋转切削具可换式钻头。在结构上采用弹簧、顶杆、球形铰组合来控制可换钻头的定位；使用一套输送器控制钻头的升降。这种设计结构克服了已有钻具结构复杂、不可靠等缺点,钻进效率高于普通绳索取心钻具10%~50%。

| Abstract: | Based on analyses about the structures and existing problems of integrally retractable alternative cutting element bits,a integrally rotary replacing cutting element bit was proposed.The combination of spring,mandrel and spherical in the structure was adopted to control the orientation of replacable bit.A suit of conveyer utility was used to operate the bit ascent and descent.This design of the bit can overcome some shortcomings such as complicated structure and not reliable performance of drilling tool.It is proved that the drilling efficiency is 10%~50% higher than ordinary wire-line coring drilling tool. |
