RADIO-WAVE GEOINTROSCOPY SYSTEM OF INTER-WELL SPACE Russian patent published in 2019 - IPC G01V3/12 

FIELD: geophysics.

SUBSTANCE: invention relates to means of inter-well logging. System consists of borehole emitter (102) and receiver (103), intended for conducting radio-wave transmission of cross-well space, measurement and control module (105) connected through repeaters (104) with emitter (102) and receiver (103) by means of a fiber-optic cable, and means for positioning the emitter and receiver in space. Radio-X-ray illumination of cross-right space is carried out by placing emitter (102) and receiver (103) into wells (101). Measuring-control module (105) consists of computers configured to perform programmed commands for control of well receiver and emitter and data exchange with them, tuning the antenna of said emitter into resonance, selecting and setting the operating frequency, controlling uniformity of conducting radio-wavelength excavations, calculating coordinates of radiation and reception points, forming an array of measured values in a given format for further processing in order to determine specific electrical resistance of the rocks under study, constructing a three-dimensional geoelectric map of the wellbore space, separating and localizing electrically contrasting inhomogeneities.

EFFECT: possibility of constructing a three-dimensional geoelectric map of inter-well space (3D) with high accuracy of localization and determining properties of inhomogeneities occurring in the space between the emitter and receiver, including monitoring the change of these properties in time.
