FIELD: method and system for forcing fluid substance into borehole made in underground bed.
SUBSTANCE: method and system are proposed for injecting fluid substance into borehole, wherein tubular drilling column with drilling bit is positioned. Drilling bit is made with channel, passing between internal space of drilling column and borehole, and with moveable closing element, meant for selective closing of channel in closed position. Additionally provided is tool for forcing fluid substance, having inlet part of tool and outlet part of tool, while the method includes moving tool for forcing fluid substance through drilling column to closing element and using tool for forcing fluid substance for moving closing element from closing position, moving outlet part of tool for forcing fluid substance along channel and injection of fluid substance into borehole from internal space of drilling column through tool for forcing fluid substance into borehole.
EFFECT: reliable and safe influx of fluid substance into borehole through drilling column with drilling bit, held on its lower end.
