If you plan to work on a drilling site, you should know the types of ram BOPs. A ram BOP is a blowout preventer that uses a pair of steel plungers that oppose each other (rams). The rams can extend towards the wellbore’s center to restrict the flow of fluids or retract open to permit the flow. So, what are the various types of ram BOPs?
Here are the four different types of Ram BOPs:
- Pipe Rams
- Shear Rams
- Blind Rams
- Blind Shear Rams
1) Pipe Rams
Pipe rams close the spherical space where the wellbore or blowout preventer and the pipe meet. When the pipe Ram closes around the diameter of the wellbore’s meeting point and the pipe in the outside, fluids cannot flow through any opening around the area. It prevents liquids from flowing through the annular space but does not block those flowing within the drill pipe.
2) Shear Rams
This blowout preventer closing element uses hardened and fitted steel blades to cut the drilling pipes every moment the BOP gets closed. It then closes fully to seal the wellbore. Oilfield operators can use the shear rams to regain pressure control in the wellbore when other alternatives have failed. It always serves as the last resort.（When the shear rams cut the pipe, it remains hanging in the BOP stack. The drill pipe joint may also suffer some damages, but the other string will stay in good condition. ）
Now you have a preliminary understanding of the Pipe Rams and Shear Rams, two important types of Ram BOPs.In our next update, we will introduce the remaining two types of Ram BOPs. Please keep following our website.
