A kind of tubing string boring with pressure anchor ear, it is characterised in that: include sealing anchor ear and Anti-skip anchor ear, seal anchor ear and anti-skidding
Anchor ear combination forms anchor ear, and Anti-skip anchor ear inwall is provided with the Non-slip material coordinated with drilled tubing string, seals through on anchor ear setting
Be equipped with drilled tunnel with pressure, the drilled tubing string corresponding with drilled tunnel with pressure form drilled position, and drilled position surrounding with
Drilled tunnel with pressure seals and coordinates.
The Non-slip material arranged on described Anti-skip anchor ear inwall is anti-slop serrations, and anti-slop serrations is engaged with drilled tubing string.
Being fixedly installed gasket ring in described drilled tunnel with pressure, gasket ring is fitted with drilled tubing string, boring with pressure
Passage is coordinated with the sealing of drilled position surrounding by gasket ring.
Described gasket ring is central column, is divided into arc shape with drilled tubular pipe connection contact portion.
Being provided with annular groove in described drilled tunnel with pressure, gasket ring is fixedly installed in annular groove.
Described sealing anchor ear and Anti-skip anchor ear are connected by screw bolt and nut to be held tightly on drilled tubing string.
It is provided with closure gasket groove and connecting screw hole on described sealing anchor ear outer wall, seals anchor ear by connecting screw hole with pressure
Boring gate valve connects, and seals anchor ear and is coordinated with boring Gate-valve sealing with pressure by closure gasket groove.
Employing the utility model has the advantage of:
1, use this utility model can realize boring with pressure to tubing string, and it is higher to seal anchor ear pressure-bearing, is designed with anti-skidding armful
Hoop, prevents from sealing anchor ear displacement in boring procedure with pressure, it is ensured that effectively seal, greatly reduce operating risk.
2, this utility model gasket ring is designed to central column, is arc with drilled pipe contact portion, facilitates sealing gasket
Ring is processed with annular groove, can effectively shorten process-cycle and processing cost.
