YSZ-A HYDRAULIC STAGE CEMENTER

Features

  • The YSZ-A Hydraulic Stage Cementer eliminates the need to use a freefall Opening Plug to open the circulation ports. Therefore, it is applicable for various well deviations.
  • The internal-closing structure and non-rotating closing sleeve design eliminate the possible damage to the closing sleeve when drilling out accessories.
  • The pressure-relief design eliminates fluid trapping and compression which might occur while opening and closing the circulation ports.
  • All accessories are non-rotating and made of easily drillable materials.
