Прибор по п.2, отличающийся тем, что съемная гильза выполнена разрезной вдоль ее оси. ! 4. Прибор по п.2, отличающийся тем, что изоляция антенного провода в кольцевой выемке выполнена путем плазменного напыления слоя керамики на основе смеси оксида алюминия и диоксида титана. !5. Прибор по п.1, отличающийся тем, что блок электроники содержит не менее двух передатчиков и не менее двух приемников, соединенных с измерителем удельного электрического сопротивления горной породы по разности фаз и отношению амплитуд принятых сигналов. 1. The electromagnetic logging tool during drilling, comprising a housing in which at least two receiving and two transmitting antenna assemblies are connected to the electronics unit, characterized in that the housing of the instrument is made in the form of an all-metal cylinder, inside of which two longitudinal holes are drilled, one of which is made through to pass the drilling fluid, and in another placed an electronics unit. ! 2. The device according to claim 1, characterized in that each antenna assembly contains an antenna wire containing at least one turn and a resonant capacitor, a removable sleeve for installation on the outer surface of the device body, longitudinal slots are made in the sides of the removable sleeve, of which ferrite inserts are installed, the antenna wire is laid in an annular recess on the inner surface of the liner perpendicular to its slots and is connected through the pressure glands to an electronic unit for measuring the electrical resistivity of the rock. ! 3. The device according to claim 2, characterized in that the removable sleeve is made split along its axis. ! 4. The device according to claim 2, characterized in that the insulation of the antenna wire in the annular recess is made by plasma spraying a ceramic layer based on a mixture of aluminum oxide and titanium dioxide. !5. The device according to claim 1, characterized in that the electronics unit contains at least two transmitters and at least two receivers connected to a rock resistivity meter by phase difference and amplitude ratio of received signals.
