COMPLEX MAGNETOMETER-INCLINOMETER FOR SURVEY OF WELLS OF VARIOUS PURPOSES Russian patent published in 2024 - IPC G01V3/18 E21B47/22 G01R33/02 

FIELD: measuring.

SUBSTANCE: invention relates to measurement geophysical equipment and is intended for logging when searching for and exploring iron-ore deposits, as well as weakly magnetic objects, investigating parametric and oil-and-gas wells. Complex magnetometer-inclinometer contains three mutually orthogonal rigidly fixed accelerometers, three mutually orthogonal rigidly fixed ferroprobe, sensor signals conversion unit, magnetizing and compensation coils, quartz generator, frequency divider, analogue-to-digital converter of double integration (ADC), shift register, signal modulator. Device additionally includes a control pulse distributor, an ADC integrator charge and discharge clock generator connected to the control pulse distributor, a differential ferroprobe connected to the sensor signal conversion unit. Differential ferroprobe is installed at a distance from the magnetizing coil and inside the compensation coil, which are connected to a control pulse distributor, to which a pulse generator for controlling charge and discharge cycles of the ADC integrator is also connected.

EFFECT: wider range of the channel for measuring magnetic susceptibility without reducing sensitivity and high speed of detecting other channels.
