At the present time in the process of drilling wells with complex profiles telemetry systems of well trajectory monitoring are extensively used. They improve drilling efficiency, provide operational accuracy of drilling and provide information about drilling dynamics in real-time to optimize drilling parameters and to improve the rate of penetration and well durability. Operational information about the state of reservoir, obtained by measuring gamma radiation, resistance and telemetric measurements allows to adjust the well trajectory by providing well drilling in the most productive part of the reservoir. To control the predetermined direction of the wellbore axis in space, allocating areas of its bending, which can cause problems during drilling and exploitation, and determining the true depth of productive layers, as well as spatial bottomhole position (zenith angle and azimuth) at individual points of the wellbore using inclinometer sensors. One type of such sensors are gyroscopic instruments, which allow to orient the wellbore in space during construction providing the origin from certain existing coordinate system in measuring angles and angular velocities. The most modern, promising and fastest growing among the gyroscopes are fiber optic devices.

The article describes the results of study the experimental sample of inertial unit using in navigation systems, constructed on the basis of solid-state fiber optic gyroscopes of Russian serial production. The study showed that these sensors had the required accuracy characteristics; sensor errors did not exceed the allowable values. By providing geostationarity conditions of navigation system while drilling these sensors can be used in the development of telemetry systems of well trajectory monitoring
