Tying module for drilling perforators and core samplers


  • Tying drilling perforator and core sampler to depths during perforation and rock sampling from cased and open borehole walls;
  • casing metal and cement stone sampling using drilling core samplers in cased wells;
  • Perforation of pay beds of cased holes with PS-112 and PGSP drilling perforators.


  • reducing the time to minimize well downtime for coring and perforating operations
  • accurate installation of the equipment in the borehole, especially when rocks sampling and drilling perforations in formations representing a thinly layered alternation of permeable consolidated interlayers;
  • tool modular design simplifies and facilitates repair work and transportation
