MEASUREMENTS WHILE DRILLING Russian patent published in 2014 - IPC E21B47/12 E21B47/20 E21B47/02 G01V5/12

Abstract RU 2509210 C1

FIELD: mining.

SUBSTANCE: system of measurements while drilling is proposed, comprising the following connected components: a module of an electric generator-pulsator, a module of an inclinometer and a module of gamma logging, including telemetering units. At the same time the specified telemetering system additionally comprises a unit of analysis and control of a switchboard and a switchboard connected to the specified modules. Besides, the inlet of the switchboard analysis and control unit is connected to the outlet of the control unit of the gamma logging module pulsations and the first inlet of the switchboard. And the outlet of the switchboard analysis and control unit is connected to the inlet of switchboard control. Besides, the second inlet of the switchboard is connected to the outlet of the inclinometer module pulsations control unit, and the outlet of the switchboard is connected to the inlet of the pulsator, installed in the module of the electric generator-pulsator.

EFFECT: increased quality of well survey due to increased reliability of information transfer from a bottomface to surface.
