WELL DETECTION USING INDUCED MAGNETIC FIELDS

摘要

A well detection system includes a signal generator module and a detector module. Signal generator module is coupled to a well structure, and causes the well structure to emit a signal. The emitted signal is measured by the detector module. Based on measurements of the signal, the detector module can determine information pertaining to the source of the emitted signal and can, for example, determine the location of the well structure relative to the detector module.

主权项

1. A method for locating a first well structure relative to a second well structure, the method comprising:
alternately charging a first set of capacitors while discharging a second set of capacitors into the first well structure, and discharging the first set of capacitors into the first well structure while charging the second set of capacitors; detecting, from the second well structure, magnetic field pulses corresponding to the discharging of the first and second sets of capacitors into the first well structure; determining information pertaining to a location of the first well structure relative to the second well structure based on the detected magnetic field pulses.
