Аnnotation: The results of a detailed spatiotemporal comparative analysis of the data obtained by platform and bottom inclinometers at the V. Filanovsky field are presented. It turned out that the slope spectra obtained by the platform inclinometers fundamentally do not coincide with the data of the bottom sensors. It turned out that platform inclinometers effectively detect exogenous deformation effects and practically do not identify deformations of the seabed associated with the processes of field development. Based on the geomechanical model of poroelastic inclusion, mathematical modeling of the spatial distribution of the slopes of the seabed during the period of intensive injection of wa-ter into the reservoir under development was carried out. The proposed model shows that only the system of bottom inclinometers is an element of geodynamic monitoring. It is concluded that sensor systems installed only on the platforms themselves (accelerometers, inclinometers, GNSS) do not belong to geodynamic monitoring systems (geodynamic polygons) and cannot ensure safe and rational subsurface use.
