ABSTRACT:
A highly effective module for preventing corrosion of oil well pipes and equipment and for preventing resulting fires and explosions. The module is a collar formed from slitted and expanded metal net and is adapted to fit in the annular space between the oil production pipe and the outer casing of the oil well, to prevent oxygen from the atmosphere from entering the annular space at the top of the well, and to exclude hydrocarbon vapors from the subterranean production zone from entering the annular space at the bottom of the well. The invention also relates to methods for extinguishing a burning oil well.
