FIELD: well drilling, particularly to change bottomhole characteristics during well drilling.
SUBSTANCE: telemetric system comprises land-bases receiving and processing equipment, electric string separator, alternating current generator installed below the separator and downhole equipment with measuring sensors and with electronic transmission unit. Electronic transmission unit is linked to the alternating current generator from above through electrical connector for power cable. Self-contained power supply module and measuring downhole equipment modules are connected to the generator by low-power wires through lower electric connector.
EFFECT: simplified structure and increased reliability of bottomhole telemetric system.
