FEATURES OF PLANNING A DETAILED STUDY OF THE HYDRODYNAMIC AND HYDROCHEMICAL PROPERTIES OF THE “YENISEISKIY” SITE OF THE NIZHNEKANSKIY MASSIF

In the coming years, an underground research laboratory will start being constructed at the Yeniseiskiy site within the Nizhnekanskiy rock mass. In this regard, arranging for subsoil monitoring is seen as a priority task to identify the required parameters of undisturbed rock mass. Specific features of hydrogeological setting within the rock mass at the Yeniseiskiy site necessitate interval monitoring in deep wells with open holes using multipacker systems. In-depth studies of sections with a discreteness of 1—2 m are required to identify the monitoring intervals. However, Russia has no hands-on experience in this matter. The article discusses international practice for arranging detailed research at analogue facilities and describes the equipment used. Interpretation of the data obtained is seen as an important part of the research with relevant technique associated with interval injection at constant pressure being discussed in the article.

Keywords: radioactive waste, underground research laboratory, hydrogeological and hydrochemical conditions, subsoil monitoring, interval studies in wells, multipacker systems, differential flow metering, interval injection.
