It is crucial for safety employees at a drilling site to be aware of the distinction between shear rams and blind rams. The ram BOPs utilize pairs of steel plungers that work in opposition to each other to avoid wellbore blowouts. They allow the tubing in wellbores to be sheared off and the wells to be sealed. However, the functionality of the two ram BOPs is distinct.
Without a pipe, a blowout preventer (BOP) known as a blind ram BOP seals against itself to seal off the wellbore. When the BOP is closed, the blind shear ram’s hardened tool steel blades will sever the tubing or drill pipe. When the well is not in use for production, blind ram BOPs seal up the access points for the tubing and drill strings. The dual ram bop is a specialized form of ram BOP that can shear through tubing strings or bigger diameter tubes in either orientation relative to the ram’s centerline.
The hefty, thick steel part of a ram blowout preventer (BOP) is called a blind shear ram. When the BOP is closed, the blind shear ram’s hardened tool steel blades will sever the tubing or drill pipe. The wellbore is then totally isolated or sealed by a complete closure. What you need to know about shear rams is detailed here.
The safety of everyone working on the drilling site depends on the oilfield operator selecting the appropriate blind shear ram BOP. Blind shear rams help control the wellbore’s pressure when it rises.
They help regulate any extra pressure that may otherwise cause ruptures and accidents in the oilfield, making them essential safety equipment. Drilling an oil well cannot begin until the optimal blind shear rams have been installed.
The blind shear rams must be fitted with hardened tool steel blades to ensure a secure installation. When the BOP stack is closed, the shear rams will easily cut the drill pipe or tubing apertures because of how well they fit. When the blind shear ram is fully closed, it seals off the wellbore.
Having a blind shear ram in your drilling strategy is crucial, but they are only used if all other BOPs have failed. A blind shear ram is ideal for restoring order when the well is overflowing, and pressure is building.
Picking the right blind shear ram for your well-drilling job requires understanding how its unique functions will be used. Researching the blind shear ram’s specs will allow you to make an informed decision. Before purchasing a bore rim, you should know that typical sizes range from 7-1/16′′ to 21-1/4. Before making any final decisions, it’s wise to get expert advice.
When the well is not in use for production, blind ram BOPs seal up the access points for the tubing and drill strings. One variant of ram BOP is the Dual Shearing Blind Ram (DS). In addition to bigger diameter tubing, it can also cut through several tubing strings perpendicular to the ram’s centerline. During routine drilling operations, the DS by BOP Products can be used as blind rams as well.
The blind-ram BOP must have a remote-control-compatible safety cover. Only the driller knows if there is a drill string in the borehole at any time during the drilling operation. Either the blind ram BOP or the pipe ram BOP must be closed. The blind-ram BOP’s reversing valve has a safety cover to prevent the assistant driller, working from a remote console, from accidentally turning off the BOP.
You can’t stress enough how crucial blind shear rams are to your well-drilling process. After settling on a set of blind shear rams, it’s essential to understand how they function and how to set them up in the wellbore.
