    • In some example embodiments, a system includes a drill string having a drill bit. The drill string extends through at least part of a well bore. The system also includes a first vibrational sensor, positioned on the drill bit to measure, at a first location on the drill string, an amplitude of one or more of an axial vibration and a lateral vibration. The system also includes a second vibrational sensor, positioned above the drill bit and on the drill string. The second vibration sensor is to measure, at a second location on the drill string, one or more of an axial vibration and a lateral vibration. The system includes a processor unit to determine a type of vibration based on a comparison of the amplitude at the first location to the amplitude at the second location, wherein the type of vibration is at least one of bit whirl of the drill bit and a while of a bottom hole assembly that is part of the drill string.
    • 在一些示例性实施例中,系统包括具有钻头的钻柱。 钻柱延伸穿过井眼的至少一部分。 该系统还包括位于钻头上的第一振动传感器,以在钻柱的第一位置处测量轴向振动和横向振动中的一个或多个振幅。 该系统还包括位于钻头上方和钻柱上的第二振动传感器。 第二振动传感器在钻柱的第二位置处测量轴向振动和横向振动中的一个或多个。 该系统包括处理器单元,用于基于第一位置处的振幅与第二位置处的振幅的比较来确定振动的类型,其中振动类型是钻头的位旋转和至少一个位置 作为钻柱的一部分的底孔组件。
