FOR RUNNING IN HOLE AND RETRIEVING DOWNHOLE TOOLS ON A SLICKLINE WHILST SEALING OFF A WELLHEAD
Manual ram blowout preventer “PR-Tekhno” is used as a section of a pressure control equipment (lubricator) while performing logging or fishing in wells with X-mas trees. It is designed to seal a wellhead in the process of running slickline or wireline conveyed downhole tools in and out of a well.
The preventer is used while performing well logging or other well interventions at wellhead pressure of 35 MPa; ambient temperature ranging from -40 to +50°С and maximum wellhead temperature up to +100°С.
Manual ram preventer “PR-Tekhno” is an emergency locking equipment enabling running in and retrieving downhole tools conveyed either on a scraper slickline or a cable wireline while keeping a wellhead sealed.
Depending on its type “PR-Tekhno” preventor by OOO NPF “TehSmart” can have the following design options:
- with wedge cut piston,
- with straight-sided piston.
Replaceable rubber seals are shipped with any preventor by default. They are universal and fit both types of pistons.
