At construction of new wells and drilling of lateral boreholes from old wells the irreplaceable tools for
geophysical provision of directional survey (spatial definition of borehole axes of any type) are gyroscopic inclinometers
(gyro-inclinometers), based on principles of analytic gyro-compassing, the parameters of which are able in maximal degree
to satisfy requirements of trade and ore geophysics.
Gyroscopic inclinometers are intended for measurement of zenith angles, geographical azimuth
and angular position of the borer’s deflecting tool with a view to define spatial position of an axis of oil-and-gas and any
other boreholes at well-boring, control checks and maintenance works.
The gyroscopic inclinometers can be applied as independently or in structure of some well-logging system
at geophysical surveying of any wells: vertical, inclined, directional, horizontal, cased or uncased boreholes, in process
of drilling or to be drilled including those in rocks with ferromagnetic inclusions and also for measurement of spatial position
of pipelines laid in remote places, e.g. on a bottom or under water basin.
Gyro-inclinometers are also applied for definition of verticality and azimuth of metalwork
in house-building. Gyroscopic inclinometers function on principles of analytic gyro-compassing and do not require time and
additional equipment for initial alignment prior to operation. Measurements within wells can be made both at lowering or hoisting
the downhole tool. All measurements are performed in real time to enable the on-line control of a borehole deviation.
Gyro-inclinometers offer the embedded program of self-adjustment and functional control.
Application of self-adjustment mode provides observability of faults at borehole measurement and their compensation. The data
are displayed on PC and saved on a magnetic medium. The profile calculations of a measured borehole section are displayed
on PC and can be printed out. All resulting read-outs are dumped in LAS-form.
Qualified experts of enterprise conduct a regular work to improve the characteristics of new gyro-inclinometers.
The inclinometers comply with all modern trends of drilling activities, such as:
cluster drilling with high density of wells;
operation mode with a boring and deflecting tools’ gyro-orientator at drilling-out of lateral boreholes;
high-accuracy measurements at collar piping verticality checks.
Unlike all other models these gyro-inclinometers offer the following features:
at drilling vertical sites of boreholes the inclinometers enable the stable azimuth checks of a borehole
axis starting from zenith angle 0.3 degrees and thus provide for safe (trouble-free) drilling at high density of boreholes’
unique in Russia gyroscopic inclinometers measuring an azimuth in all range of inclination angles;
have no time restrictions for operation in boreholes;
at drilling the lateral boreholes in old wells the special soft program allows orienting of deflecting
tool and pointing the boring tool to specified azimuth from upright position of a casing string without cutout of pipe section.
