A system to extinguish oil well fires includes screens for dispersing an oil jet through the walls of a cylinder by the use of layered mesh screens, resulting in the reduction of the velocity of the oil jet by impact with the screens and the interior wall of the cylinder to a point where it will then flow down the wall of the cylinder by gravity. This system also includes a collar around the cylinder, through which water will be pumped and sprayed on the cylinder through holes formed in the collar and directed at the cylinder. Additional holes may also be formed and may also be formed and directed to the surrounding area to help extinguish any remaining ground fire. This system allows the flame of an oil well fire to go into the cylinder and the combustion in the cylinder will then produce carbon dioxide and water. Carbon dioxide is prevented from escaping by a flapper valve, which seals the cylinder from a rush of external air. Because of the absence of oxygen, any flame entering the cylinder is immediately extinguished, and once the fire is extinguished and the cylinder is removed, the oil well can be capped according to conventional methods.
