Abstract
A casing is lowered in a well for production of an underground petroleum deposit. The casing includes a number of tubular sections connected successively to each other by special tubular connectors, at least certain of these being modified, and the casing being cemented in position when installed in the well. These special connectors include housings for one or several sensors and other housings, if necessary, for the electronic acquisition or transmission circuits. The different connectors for the device are interconnected by cables and to an installation on the surface by a multi-line cable for the electrical supply to the electronic modules and transmission of the data acquired. This arrangement permits prewiring of the different connectors, thus simplifying the positioning of the device during operations for equipping the wells.
