The Functions of Blowout Preventers (BOPs) in Drilling Operations

rotary BOP

Oil and gas wells are sealed, managed, and monitored by a huge, specialized BOP called an annular blowout preventer.

The annular BOP can be split into conical annular BOP and spherical annular BOP depending on the shape of the sealing rubber core.

Four components make up the majority of its structure: the piston, rubber core, top cover, and shell. The annular blowout preventer can use a rubber core to seal a variety of annular voids of varied diameters when drilling equipment, tubing, or casing are present in the well. It can completely seal the wellhead when there isn't a drilling tool in the well. Additionally, during drilling, coring, logging, and other operations, it can seal the annular area created by the kelly, coring instruments, cables, steel wires, and the wellbore.


The shell, side door, oil cylinder, cylinder head, piston, piston rod, locking shaft, seals, ram, and other components make up the majority of a ram blowout preventer. It operates by using hydraulic pressure to push the piston, which then drives the ram to close or open the wellhead in order to accomplish the sealing and opening of the well.

Hardware API

These crucial BOP parts include flanged crosses, drilling spools, male and female adapters, and more for building and maintaining high-quality BOPs. The apparatus can be altered to meet any BOP specifications. If you need to customize a new blowout preventer for your oil well or fix an old one, quality API equipment can help.
