INCLINOMETER Russian patent published in 2005 - IPC

FIELD: geophysics.

SUBSTANCE: inclinometer has ground-based computer, via logging cable connected to well device, which has temperature sensor, connected to one of outputs of digital processing block, to other outputs of which outputs of acceleration measuring means and platform rotation angle sensor are connected. Also, device has one-axis stabilizer, on platform of which rigidly placed are acceleration measuring means and stabilizer platform rotation angle detector. Well device additionally has three-coordinate ferro-probe Earth geomagnetic field sensor at the platform, two sensitivity axes of which coincide with sensitivity axes of accelerations measurements, and third one - with longitudinal axis of well device. Outputs of three-coordinate ferro-probe sensor are connected to inputs of digital processing block inputs, output of which is connected to ground block and central unit input, which through power amplifier is connected to sensor of momentum, which rotates platform around stabilization axis.

EFFECT: higher precision.
