Oil & Gas Well Annular Blowout Preventer / API 16A Annular BOP For Well Control
BOP is an important part of well-control equipments. It mainly applies to control wellhead pressure during drilling,workover operations and formation testing etc to prevent well blowout effectively and realize safe construction.
There are two structure models of annular BOP, tapered rubber and spherical rubber. Upper housing and the body have two connections of bolts and claw chuck. Annular BOP with spherical rubber is composed of five parts as upper housing, body, piston, spherical rubber and anti-dust ring. Annular BOP with tapered rubber is composed of seven parts as upper housing, wear plate, body, piston, tapered rubber, anti-dust ring and supporting cylinder.The dynamic seal of annular BOP adopts the sealing ring of lip structure, which reduces the wearing of sealing ring maximally, and the sealing is reliable; the rubber is not easy to fold back, and there is the effect of funnel; and the well pressure has the function of assisting sealing. Etc.
