Function of Ram blowout preventer
- When drilling pipe, tubing and casing overflow or blowout occurs in the well, the annular space formed by the corresponding pipes and the wellbore can be sealed.
- When there are no pipes in the well, the wellhead can be completely enclosed.
- Under special circumstances, drilling fluid circulation and throttling and killing operations can be carried out through the flange outlet on the side of the housing.
- Under special circumstances, the shearing ram can cut off the drilling tools to achieve the purpose of sealing the well.
- Pipe rams can also hang drilling tools when necessary.
Types of Ram blowout preventer
- According to the use of ram, ram blowout preventers can be divided into fully sealed, semi-sealed, reducing, shearing and cable ram;
- According to the ram chamber, Ram BOP can be divided into single ram, double ram, and triple ram;
- According to functions, ram blowout preventers are divided into pipe ram, fully enclosed ram, shear ram, and variable diameter ram.
Structure of ram blowout preventer
Ram BOP is mainly composed of housing, side door, oil cylinder, piston and piston rod, locking shaft, end cover, ram and other components. There are three ways to connect the upper and lower ends of the ram blowout preventer housing: threaded connection, flange connection, and clamp connection.
