FACILITY FOR HORIZONTAL WELL LOGGING Russian patent published in 2009 - IPC G01V5/10 

FIELD: mining.

SUBSTANCE: facility for horizontal well logging contains lowered into well autonomous geo-physic modules connected between them into assembly, to upper part of which there is connected device for connection of assembly with flow string; facility also contains surface complex including depth gauge and personal computer; also assembly contains modules of gamma-logging, of three-probe neutron-neutron logging, of multi-probe electric side logging, of wave acoustic logging, of acoustic profile gauge, and of inclinometer; in lower part of assembly there is installed nozzle for outlet of well washing fluid into annular space at well washing, and each autonomous geo-physic module contains autonomous supply unit, signal conversion and memory units.

EFFECT: obtaining efficient complex of apparatus for logging horizontal bore holes of wells and upgraded information value of geo-physic survey of horizontal wells at simultaneous reduction of break down rate of this kind of operations.
