The invention describes a system for extinguishing fires in oil wells subjected to very high pressures, and cooling of the surrounding ground. The base of the system is, for example, of conical shape resembling a volcano. The flames are stifled by introducing a non-flammable gas (e.g. nitrogen or liquid carbon dioxide) or water into the system through holes (4a, 4b) in the conical section. The turbulent propagation of this gas, achieved by using angle connectors in the system, occurs in the same direction as the flames and is intensified in an upward direction by the conical shape of the system. The outlet via the crater (1) is a form of eruption encompassing all the flames, and nitrogen is directed downward to cool the surrounding ground.
