    • Disclosed is an apparatus for displaying three-dimensional motion of a drill string in a borehole penetrating the earth to a user in real time. The apparatus includes: an accelerometer configured to measure acceleration in at least three directions; a strain sensor configured to measure strain or a bending moment at the drill string in two directions; a magnetometer and configured to measure an earths magnetic field to determine rotational velocity of the drill string; a processor disposed at a surface of the earth and configured to receive the measurements from the accelerometer, the strain sensor, and the magnetometer and to process these measurements to estimate the three-dimensional motion of the drill string; a display configured to display the motion of the drill string to the user; and a highspeed telemetry system configured to transmit measurements from the accelerometer, the strain sensor, and the magnetometer to the processor in real time.
    • 本发明公开了一种用于实时显示穿透地球到用户的钻孔中的钻柱的三维运动的装置。 该设备包括:加速计,被配置为测量至少三个方向上的加速度; 应变传感器,所述应变传感器构造成沿两个方向测量所述钻柱处的应变或弯矩; 磁力计并被配置成测量地磁场以确定钻柱的旋转速度; 处理器,其布置在地球的表面并且被配置为接收来自加速度计,应变传感器和磁力计的测量结果并且处理这些测量结果以估计钻柱的三维运动; 显示器,其被配置为向用户显示钻柱的运动; 以及高速遥测系统,其被配置为实时地将来自加速度计,应变传感器和磁力计的测量结果传输到处理器。
