摘要
FIELD: well logging in the course of drilling; applicable in performance of electromagnetic well logging in the course of drilling. SUBSTANCE: method includes setting-up of alternating two-frequency electric field in zone of control by connection of logging system to electric separator of telemetering system with electromagnetic communication channel. For measurement of response signals of controlled medium, use is made of said electrical separator, metal bracket and dielectric body of instrument container accommodating well logging apparatuses. Method is realized with the help of device having telemetering system with wireless electromagnetic communication channel, current transducers and voltage converters, three electronic switches, two-channel digital-to-analog converter, multichannel analog-to-digital converter, command memory, results storage memory, input-output device and digital signal processor with switching control port and serial port. Electrodes for setting up and measurement of electric field are used in the form of electric separator, metal bracket, body point of well logging apparatuses and dielectric body of instrument container accommodating logging apparatuses. EFFECT: higher reliability and information content of determination of parameters of drilled beds. 7 cl, 3 dwg
