IGMC-45-100/80
|
Gimballess gyroscopic inclinometer (GI) IGMC-45-100/80 is
designed to measure directional readings, inclination angle,
whipstock declination and its position to the apsidal plane of the
well depending on the depth*1 of deviated and horizontal, cased and
open wells, may be installed into hardwire telemetric bottom-hole
systems as well.
The advantages of the given GI over similar CIS inclinometers are
the following:
the GI does not require initial positioning on the ground;
with the GI the measurements can be taken when powered at any well
point;
the GI provides continuous and point inclinometry and their prompt
alignment;
the GI provides the taking of fixed measurements irrespective of
the time the measurements of the inclined well are taken. The
measurements are taken in real time;
depending on the accuracy of inclinometric measurements required
the user can vary the time of data entry in the point mode;
the GI provides long-term continuous inclinometry owing to special
work modes that allow to minimize the integration error;
in GI a “control-test” is foreseen, allowing to:
a) minimize tests before well descent without
the use of the inclinometric table;
b) automatically control the integrity of the
measurements taken during the process of work;
c) automatically control angular and linear
tool stillness during station time;
the GI is designed as a modular construction, allowing to reduce
the volume of maintenance and repair works.
The system software allows you to promptly receive intermediary
results of the investigation and the well angle in graphic and
numeric form, inspect its every section in detail.
