摘要： A steerable, magnetic dipole antenna for Measurement-While-Drilling (MWD) or Logging-While-Drilling (LWD) applications. The antenna elements use a hole arrangement in addition to grooves in a steel tool body, which is typically a drill collar. This antenna embodiment is extremely robust, meaning that does not significantly reduce the structural integrity of the tool body in which it is disposed. The antenna embodiment is also relatively wear resistant. The resultant magnetic dipole generated by this antenna is also electrically steerable in inclination angle from a common origin. A variable dipole moment inclination angle combined with independently measured tool rotation orientation during normal drilling allows the antenna to generate a magnetic dipole moment that may be directed at any three dimensional angle and from a common origin point at the centroid of the antenna.

摘要翻译：用于钻井测量（MWD）或钻井记录（LWD）应用的可操纵的磁偶极子天线。天线元件除了通常是钻铤的钢工具主体中的凹槽之外还使用孔布置。该天线实施例非常坚固，这意味着不会显着降低其所在的工具主体的结构完整性。天线实施例也是相对耐磨的。由该天线产生的所得磁偶极子也可以从公共原点以倾斜角度电动转向。在正常钻孔期间结合独立测量的工具旋转定向的可变偶极矩倾斜角度允许天线产生磁偶极矩，其可以以任何三维角度和从天线的质心处的共同起点指向。
