Today horizontal well drilling for hard-to-recover reserves is going with obligatory using of drilling steerable systems. The most technologically and economically justified is the use of telemetry systems that provide path control directly in the drilling process without lifting the tool to the surface. Modern systems make it possible to determine not only the inclinometric data, but also the technological characteristics of the drilling process and a number of properties of the formation.

The article examines the telemetric monitoring system of the wellbore trajectory, developed at the Perm National Research Polytechnic University. The device has the following features. The use of fiber optic gyroscopes with a closed loop as inclinometer sensors allows, firstly, to determine the azimuth and zenith angles of the well with high accuracy, secondly, to abandon the use of non-magnetic steels in the system casing and non-magnetic drill pipes in the column, and thirdly, to use the device when drilling near the casing of adjacent wells and magnetized rocks. The presence of a system for providing geostationary sensing elements makes it possible to use TMS in rotary drilling with an angular velocity of up to 250 min-1. The presence of a downhole turbine-generator and a set of rechargeable batteries provides the possibility of continuous operation of the device at the bottom. The system has two communication channels: hydraulic and cable in the wall of the drill pipe. The cable channel provides a data transfer rate of up to 1 Mb/sec.

The developed device is used for drilling directional and horizontal wells with a diameter of 216 to 227 mm, including rotary method. The system has no analogues in Russia for use in conditions of convergence with drilled cased wells and near magnetic disturbances.
