IMPROVED OIL WELL PERFORATOR LINERS

摘要

A shaped charge apparatus having an improved liner for a shaped charge constructed from a combination of powdered metal and selected polymer material. Powdered heavy metal and polymer binder is compressively formed into a rigid shaped charge liner under very high pressure. The polymer binder may be in powdered form and or also b e used to coat the powdered metal particles prior to compression. The compressed liner may also contain a relatively small percentage of other material to enhance lubricati on or corrosion resistance.
