ABSTRACT OF THE INVENTION A method of extinguishing fires in oil wells comprising attaching a shell which is integral with required drill guides and valves to the outer oil producing pipe or its casing, inserting at least one drill pin from said shell through the said outer pipe and at at least one level to immobilize the inner oil producing pipe (tubing) relative to the said outer one, and driving at least one drill below said level and drilling through both pipes into a closed guide diametrically opposed thereto, so that part of the wall of said outer pipe remains in two diametrically opposed positions. A device for carrying out this method comprises an arcuate shell of at least two parts of an internal radius equal to the external radius of the outer oil producing pipe or its casing and adapted to be attached to said outer wall or its casing, at least one drill housing with a drill attached to the shell at one level and at least one drill guide together with a drill attached to said shell at a level below said first level.
