Apparatus for geophysical measurements and process parameters during the drilling process and their transmission to the earth's surface for electromagnetic communication channel

摘要

Device for measuring geophysical and technological parameters in the drilling process and their transmission to the earth's surface for electromagnetic communication channel comprising downhole telemetry system (PTE) from the receiving-processing device, and comprising a drill string, electric separator configured as a separate sub, mounted directly above the downhole motor and mounted directly above the bit above-bit measuring unit (BAT) comprising a housing with a central washing chnym hole for accommodating a center electrode disposed between the insulators and electrically insulated from the housing, wherein in the recesses housing BAT arranged electronic circuit measuring sensors, a power source and a transmitter, characterized in that the housing BAT serves spindle housing mud motor which is elongated, and the recesses formed therein to accommodate electronic circuits, the measurement sensors, a power supply and transmitting device of said spindle shaft and Manuf detecting elongate omitted BAT within the housing and is connected to a chisel.
