Azimuth sensor consists of a compass, the magnetic needle
that moves on a circular rheostat. Bussol hanging for two half
shafts enshrined to the frame so that the nib, which rotates the
magnetic needle, located vertically, and block with azimuthal
reohordom - horizontal. When measuring the azimuth, magnetic
needle, with established therein spring contacts connecting the
conductive ring with one of the points reohorda. In measuring
circuit introduced reohorda azimuth plot, resistance is proportional
to the azimuth warping. The warping angle sensor consists of arc
rheostat, which is situated opposite end of arrows and a lever with
which stamped arrow. Lever and arrow are in the plane of
warping, which is perpendicular to the axis of the frame. In the
vertical position the device end of the arrow is opposite the
reohorda start lever. On tilting the device arrow deviates for this
position at an angle equal to the angle well deviation from vertical.
With the closure of source parts end of the arrow pressed against
the corner reohorda. In measuring circuit herewith introduced the
area of reohorda corner, resistance in which is proportional to the
angle of warping.
Electric scheme of inclinometers are shown in Figure 5.3.
Inclinometers IK-2 is designed to work with single-cable.
Its electrical circuit consists of a combination of electrical circuits
inclinometers ISH-3 and ISH-4. Switch position for measuring the
azimuth angle and curvature is performed using an electromagnet
L, by changing the polarity of the power source. To power the
device using DC voltage 140 V. To measure the elements of well
distortion used bridge sheme. The bridge is balanced by circular
reohordom R. The count values of azimuth and curvature angles
are made directly on a graduated scale.
Universal small-size inclinometer UMI-25 mind measure
angles and azimuths distortions no cased deep oil and gas wells,
wells of diamond drilling, as well as elements of well distortion in
the process of drilling. For the design and an electric scheme it is
