The Research of Shaped Charges with Powder Liners for Geological Borehole Perforation Authors: B. Zygmunt, Z. Wilk
The characteristics of shaped charges with metal powder liners for perforating of borehole pipes
are described. Liners were manufactured using metalic powder technology. Two type of powder liners
were made: a homogeneous one made of copper powder and a heavy one made of copper and tungsten
powder composition. X-ray pulse technique was applied to research the process of jet stream formation.
Radiograms revealed the discontinuous structure of jets formed from powder liners. The corresponding
computer simulations of jets formation are presented. |
