METHOD OF ORGANIZING AN ANTENNA OF A DOWNHOLE RESISTIVITY METER FOR A TELEMETRIC SYSTEM (VERSIONS), AN ANTENNA OF A DOWNHOLE RESISTIVITY METER FOR A TELEMETRIC SYSTEM (VERSIONS) Russian patent published in 2020 - IPC G01V3/00 

FIELD: drilling of wells.

SUBSTANCE: disclosed technical solution relates to geophysical equipment for tracking drilling of wells, specifically to versions of well resistor meter for telemetry system, intended for measurement of specific electric resistance (SER) of rocks and fluids, filling the well and porous space of rocks, its anisotropy, determining the presence of non-uniformity of SER in the study zone, associated, for example, with boundaries of geological bodies with different SER, contacts of fluids with different resistivity, as well as determining distances to these inhomogeneities of SER both during drilling of wells, and in drilled wells. Technical result is achieved by the fact that in antenna of borehole resistivity meter for telemetric system, including housing, in which case well resistor meter for telemetry system is used, at least one pair of antenna modules, which are arranged in in-phase, forming total magnetic moment and installed on opposite sides of housing, on same section of housing, in particular, antenna module is made in form of coil, which wire is wound on its base, latter is made of diamagnetic material of at least one part in form of rod, the shape of which is matched with the shape of the body section in the area of location of antenna modules.

EFFECT: technical result is creation of antenna with higher efficiency of transmission and reception of electromagnetic waves for directed measurements.
