Working Principle

An annular blowout preventer uses the principle of a wedge to shut in the wellbore. It has a donut-like rubber seal, known as an elastomeric packing unit, reinforced with steel ribs. The packing unit is situated in the BOP housing between the head and hydraulic piston.

When the piston is actuated, its upward thrust forces the packing unit to constrict, like a sphincter, sealing the annulus or open hole. Annular preventers have only two moving parts, piston and packing unit, making them simple and easy to maintain relative to ram preventers.

Product Types-Annular Blowout Preventer and Ram Blowout Preventer

  

  Blowout preventers (BOPs) are used to control blowout. The crew usually install several blowout preventers (BOP stack) on top of the well, with an annular blowout preventer at the top and at least one pipe ram and one blind ram blowout preventer below. Also, some well control techniques require both the annular and the ram blowout preventers.

  An annular blowout preventer has a rubber sealing element that, when activated, seals the annulus between the kelly, the drill pipe, or the drill collar. If no part of the drill stem is in the hole, the annular blowout preventer closes on the open hole.

  Ram blowout preventers are large steel rams, that have sealing elements. One type of ram blowout preventer is called a pipe ram because it closes on the drill pipe; it cannot seal on open hole. Blind ram blowout preventers are straight-edged rams used to close an open hole.

More BOP in the following pictures: conventional ram type, manual single gate disc type with whole sealing-stick, multi function manual single gate disc type (with whole sealing, half-sealing, and self-sealing head), tube-shaped ring-type , hydraulic double gate disc type and so on.
