Oil Well Blowout Preventer API 16A RAM BOP Cameron Type 2FZ35-70
Ram BOP with hydraulic control is a key part of well-control equipment. It’s used for controlling wellhead pressure during well drilling, workover and testing etc., preventing well blowout effectively and realizing safe construction. It can be used for the following:
With proper pipe ram sealing the annular space between casing and drilling string when there is pipe in the hole;
With blind ram sealing the well head completely When the well head is closed, use the kill manifold and choke manifold connected to the spool and the outlet of the body doing mud circulating, choking and releasing, well killing etc.;
Necessarily, drilling tolls can be hung on pipe ram.
With shear/blind rams shearing the drilling tools to seal the well in some special circs.
The hydraulic double ram BOP can be operated separately and also work with single ram BOP and Annular BOP
|1||The medium inside well flows out from the clearance between the body and door.||
