Abstract (en)
[origin: EP0533526A1] In a well (1) which is to be equipped for production from an underground deposit, a lining tube or casing (2) is lowered, which casing comprises a set of tubular sections connected in succession to each other by means of tubular connectors (3), at least some of which are modified, and it is cemented once installed in the well. These special connectors (3) comprise housings (5, 7) for one or more sensors (6) and others possibly for electronic acquisition and transmission circuits (8). The various connectors (3) of the device are interconnected to each other by cables (18) and to a surface installation by a multi-conductor cable (13) for the electrical power supply to the electronic modules and the transmission of the acquired data. This arrangement enables the various connectors to be prewired, which simplifies the installation of the device during the manipulation of well equipment. <??>Application to the monitoring of oil production wells for example. <IMAGE>
