Determination of inflow Profile and Watering Sources

Studies are based on the registration of physical fields, determined by the presence and structure of fluid flows in the wellbore and near-wellbore space. Measurements are carried out at steady-state (long-running wells), unsteady (wells with a change in the selection mode) and transient thermo-hydrodynamic fields. Unsteady modes occur after starting or stopping a well. The combination of a short start and a subsequent stop leads to transition fields. To solve the problems of determining the profiles of the inflow and the sources of watering, a complex of different-mode studies is used: in the stopped and working wells, as well as in the process of calling the inflow. Measurements are carried out within a separate interval of detailed studies. When working in wells with low reservoir pressures (non-flowing), additional measurements are taken along the wellbore in the intervals of changes in the static and dynamic levels of the medium sections. The complex geophysical equipment Sova-2, Sova-3, Sova-5, Sova-9, Flowmeter Sova-3r is used.
