directed jet explosive charge liner, directed jet explosive charge liner and method for drilling a well bore

摘要

it is an explosive jet driven liner that has a plurality of metallic powders that includes at least one high-purity metal that has a purity level of at least about 99.5%. metal powders and high-purity metal are compressed to form the directed jet explosive charge liner, and the directed jet explosive charge liner is for installation in a directed jet explosive charge. once installed in the directed jet explosive charge, the directed jet explosive charge liner must be thermally softened, so as to have a porosity level of less than about 20% by volume and be able to maintain its mechanical integrity when thermally softened. . an explosive directed jet charge that includes such liners is disclosed, as well as a method for drilling a well bore using that directed jet explosive charge that has these liners positioned therein.
