The article describes the process of operation of the telemetric control system of the trajectory of the trunk during drilling of directional and horizontal wells with a rotary controlled system. An algorithm for automated correction of the direction for drilling a well along the project profile has been developed. In the process of rotary drilling with the rotation of the entire column, the navigation block of the telemetry system, built on the basis of inclinometers and accelerometers, determines changes in the current position relative to the initial position in the three axes and, together with other drilling parameters, transfers this information to the control unit. The control unit, consisting of an electronic board with a processor unit, controllers and flash memory, detects a deviation from the design position at the current depth, then calculates the necessary path correction and transmits signals to the microprocessor control unit of the wedge drive motor controllers, which ensures the wedge drive supply voltage to the motors for the required time. Based on the studies carried out, a system of equations for calculating the position of the bit is constructed, taking into account the changes in the trajectory of the well due to the movement of the bit from the current point to the design point and a model for controlling the deflection of the bit in the spatial coordinates.

The performance evaluation of the control unit was performed at the booth on the basis of the actual drilling data for a sub-horizontal well in the territory of the north of the Perm Region in 2015 using a rotary controlled system. As a result of the research, it was confirmed that the well can be drilled in the project profile in automatic mode when using a rotary controlled system in conjunction with the developed telemetry system.
