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.
