| 摘要 |
A method of monitoring deformation and other characteristics of a casing, sandscreen, electrical heater and/or other tubular or cylindrical well equipment in a well traversing an underground formation, comprises: - providing a carrier rod having at least one recess extending along at least part of the length of the rod, in which recess a optical fiber assembly for monitoring strain, temperature and/or other physical parameters is arranged, which optical fiber assembly is along at least part of its length bonded within the recess; - lowering the carrier rod and well equipment simultaneously into the well such that the carrier rod is arranged in an annular space between the outer surface of the well equipment and the inner surface of the wellbore; - securing the carrier rod at a plurality of locations distributed along its length to the well equipment; - connecting the optical fiber assembly to an optical signal transmission and reception assembly for monitoring deformation, strain, temperature and/or other physical parameters of the well equipment. |
