Method of monitoring an intervention in a fluid exploitation well made in the subsoil, and associated interventions device

摘要

A process of monitoring the intervention of, an instrumented rod with at least one sensor for measuring a strain field along the rod, into the wall and measuring the strain field along the rod in a plurality of given shapes of evolution of the rod during the intervention. The process calculates a simulated strain field for each given shape of the rod, based on at least one first model taking account of the predetermined geometry of the well and the first model being able to determine a local buckling of the rod in the well. Further, the process compares the measured strain field and the simulated strain field in each given shape of evolution of the rod.
