Annotation:

The conducted studies have shown that the near-wellbore space is a special highly active, unstable zone of an oil reservoir. This zone state depends on many parameters that affect oil production, including the energy-mechanical balance of the near-wellbore space and the reservoir. The calculation of the skin effect value allows assessing the state of the bottomhole zone and planning the measures the purpose of which is improving the rock characteristics.

The field analysis shows that hydrodynamic studies carried out in wells make it possible to regulate measures aimed at increasing wells productivity.
