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

摘要

This method comprises the following steps: - intervention, from the surface, with the aid of an instrumented rod (24) introduced into the well (12), the rod (24) comprising at least one sensor for measuring a strain field along the rod (24); - measurement of the strain field along the rod (24) in a plurality of given shapes of evolution of the rod (24) during the intervention. The method comprises the following steps: - calculation of a simulated strain field, for each given shape of the rod (24), on the basis of at least one first model taking account of the predetermined geometry of the well (12), wherein the first model is intended to determine local buckling of the rod (24) in the well (12); - comparison between the measured strain field and the simulated strain field in each given shape of evolution of the rod (24).
