BOTTOM-HOLE TELEMETRIC SYSTEM

摘要

FIELD: geophysical instrumentation. SUBSTANCE: system relates to technology of geophysical investigations in process of drilling bore-holes. Included in system is whipstock which is made as diamagnetic and spiral with hollow rotor. Rotor is made of diamagnetic material. Diamagnetic spiral-type whipstock with hollow rotor creates strong diamagnetic body of bottom-hole instrument. Application of aforesaid bottom-hole telemetric system ensures high accuracy of measuring geophysical parameters at bottom hole. EFFECT: higher efficiency. 1 dwg
