Designed for safe, good pressure control during drilling and workover operations, the Annular BOP is a large valve designed to seal, control, and monitor oil and gas wells. The valve rotates during drilling to maintain a seal around the drill pipe. The Annular BOP helps to maintain a good seal on the oil to prevent catastrophic blowouts. The Annular BOP consists of a valve body, upper housing, sealing elements, dust ring, and piston. These blowout preventers have a resilient seal, a type of valve similar to a large rubber ring, which can be mechanically squeezed inwards to seal the drill column, casing, bare borehole, or pipe. It provides a robust, reliable blowout preventer, is easy to maintain, and is widely used offshore (subsea and surface) and onshore. The ring blowout preventer is compact and can seal any size of square drill pipe, drill stem, tool joint, drill collar, casing, or cable. The sphere also provides positive pressure control for pulling the drill pipe out of the hole.
The HRSB takes the Drilling Orb Preventer (BOP) and customizes it to suit your continuous tubing operation.
An annular BOP operates differently from a ram blowout preventer.
It seals the annular space between the tubing, casing, and drill pipe. It also helps to maintain the seal when the casing, tubing, or drill pipe leaves the borehole. Unlike the RAM blowout preventer, the Annular BOP can seal a wide range of pipe sizes. It seals the well and prevents the uncontrolled escape of oil. It also prevents unwanted material from building up and exploding in the system while drilling. This ensures the safety of workers on the drilling site.
Large rubber core storage capacity, high switching pressure sealing capability, and low frictional resistance.
With a hemispherical head, there is no stress concentration when bearing pressure; the casing is evenly stressed and easy to dismantle and install.
The long-life sealing element provides a reliable seal after hundreds of full working pressure tests.
Robust, simple construction - only five main components simplify maintenance
Seal element design provides a long peel life.
