摘要
Systems and methods for well-drilling operations involving magnetic ranging with a rotating magnetic source are provided. In one embodiment, a system for determining a relative location of a magnetic source includes a three-axis magnetometer and data processing circuitry. The three-axis magnetometer may measure a time-dependent magnetic field caused by a magnetic source rotating about an axis, which may include two transverse components transverse to the axis and the data processing circuitry may determine a transverse angle of rotation of the measurements such that one of the two transverse components is ±π/2 radians out-of-phase with the other when the measurements are transformed by the transverse angle of rotation. The data processing circuitry may determine a spatial relationship between the magnetic source and the three-axis magnetometer based at least in part on the transverse angle of rotation.
