作者和他的同事们在对实际钻头和单齿圈矛轮片的运动状态的实验测定中,采用双极座标系统严格推导出单齿圈牙轮片的各运动参数之间的关系式,从而回答了钻头牙齿冲击井底的速度大小和牙齿与井底之间存在的滑动量问题,为钻头设计和使用提供了新鲜的参考资料。
The author and his colleagues used the bipolar coordinate system to strictly deduce the relationship between the motion parameters of the single-tooth ring and the single-ring lap lap slice in the experimental measurement of the actual drill bit and the single-ring lap lap motion. Which answers the question of the speed of bit impact on the bottom of the hole and the slip between the tooth and bottom of the hole, which provides a fresh reference for the design and use of bit.
