发明名称 RECEIVING COIL OF TELEMETRIC SYSTEM, TRANSFERRING INFORMATION BY MAGNETIC FLOW VIA COLUMN OF PIPES
摘要 FIELD: drilling and operation of wells, possible use for receiving information transferred by well module of telemetric system by means of magnetic flow via column of pipes. ^ SUBSTANCE: coil has body made of non-magnetic material in form of cylinder with longitudinal slit and sides, on external surface of cylinder winding is wound. Under the winding a permalloy layer is made. Winding is protected by grounded screen, made of electro-conductive magnetic material. ^ EFFECT: increased quality of receipt. ^ 2 dwg
