METHOD OF TIGHTNESS OF SLOTS ARRANGEMENT IN ZONE OF WELL RESISTIVITY METER LOCALIZATION (VERSIONS) AND RADIO-TRANSPARENT UNIT FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2019 - IPC E21B47/12 G01V3/18 G01V5/04 

FIELD: geophysics; drilling of soil or rocks.

SUBSTANCE: invention relates to geophysical equipment for tracking drilling of wells, namely to methods for tightness of slots in a wall of a drill pipe and radiotransparent blocks for their implementation in order to measure during drilling electric resistance of rocks with a borehole resistivity meter located inside a drill pipe. Unit shall be radiotransparent, i.e. which transmits electromagnetic waves, in order to measure electric resistance of rocks by means of a downhole resistivity meter located inside the drill pipe. At that, the slot in the wall of the drill pipe, into which the radiotransparent unit is installed, shall not pass through the drilling fluid under the effect of excessive pressure both from the outside of the drill pipe, and from inside the drill pipe. Radiotransparent unit used to arrange tightness of the slot in the wall of the drill pipe shall not reduce the inner diameter and increase the outer diameter of the drill pipe, shall have higher reliability and have a long period between maintenance. Besides, it shall be possible to perform maintenance of radiotransparent unit in non-specialized premises.

EFFECT: task of the claimed invention is development of versions of the method of tightness tightness organization, made in zone of localization of borehole resistivity meter and versions of radiotransparent unit for its implementation.
