FIELD: well drilling, possible use in informational and measuring systems of drilling plants for transferring information about face parameters. ^ SUBSTANCE: system for transferring face information during drilling contains measuring and transforming equipment, positioned in lower part of drilling tool, and receiving registration equipment, positioned on the surface. System contains toroid winding with core, made of ferromagnetic material, positioned coaxially on top of lower end of technical column, and cable, connecting the winding to receiving registration equipment. In accordance to one of variants, system contains one more toroid winding with core, made of ferromagnetic material, positioned coaxially on top of drilling pipe, while power amplifier for measuring and transforming equipment is connected to winding. In accordance to another variant, output of power amplifier of well measuring and transforming equipment is installed between drilling column and its lower part, electrically isolated from the former by isolation insert. ^ EFFECT: increased reliability of system and increased information transfer speed. ^ 2 cl, 3 dwg |
