Used in conjunction with hydraulic control system, the annular BOP seals off the annulus of different sizes when pipes are in use in the hole. An annular BOP can also seal off the annular space which is formed by Kelly, coring tool, cables, wire rope etc. and well bore when no pipe is in it.
API 16A 13 5/8" 10000psi Shaffer annular BOP for drilling
Description
API 16A Annular blowout preventer is manipulated by hydraulic control system. When it is shut off, high pressure oil flows into piston underside closed cavity through the oil port in central shell, to push piston upwards, and the conical surface of piston squeezes rubber core. Due to the restrictions of head cover, rubber core can’t go upwards but is pushed towards the center of wellhead until it encloses drilling tool or enclose wellhead totally to shut the well. When well needs to be opened, manipulate the reversing valve of hydraulic control system, so that high pressure oil should flow into the open cavity on top of piston through the oil mouth on shell, to push piston downwards and decompress closed cavity, in which case, the extrusion force on the conical surface of rubber core is removed, and the rubber core is reset gradually with the action of its own elastic force to open wellhead.
