Abstract
The apparatus includes a pad (20) pressed against the wall of a borehole (12), the pad comprising a plurality of detecting devices (42, 43, 44, 45) disposed in alignment along the longitudinal direction of the borehole. Each detecting device includes a housing (112, 113) having complementary ends fitted with electrical connectors. The end of one housing (112) is extended by first skirts (117, 118) suitable for interfitting between second skirts (121) of the complementary end of the housing (113) of an adjacent detecting device. An annular element (111) and screws (120, 122) fixed to complementary ends together thus constituting a rigid pad (20) which can be disassembled.
