breakdown of the main components in an accumulator
Understand all the important parts in an accumulator that work togheter to bring efficiency and safety to the oilfield.
These are pressure vessels that store hydraulic fluid under high pressure using a gas (usually nitrogen) as a compressible medium. They ensure rapid delivery of hydraulic power when needed to operate the BOP. A typical unit might have 4 to 8 bottles, each rated for high pressure (e.g., 3,000 psi or higher).
The accumulator unit includes one or more hydraulic pumps that pressurize the hydraulic fluid. Dual pumps are common for redundancy, ensuring that operations can continue even if one pump fails. These can be powered by diesel engines (e.g., Hatz or Kohler).
The system is equipped with various types of control valves, including:
-
4-Way Selector Valves: To direct the hydraulic fluid to different BOP functions, such as opening or closing the rams.
-
Pressure Relief Valves: To protect the system from over-pressurization.
-
Isolation Valves: Used to isolate parts of the system for maintenance or to prevent leaks.
-
High-Low Bypass (Diverter) Valves: To control flow rates depending on whether high or low pressure is needed.
-
These devices help maintain a consistent hydraulic pressure, ensuring that the correct force is applied to the BOP. There are often two regulators for dual pressure control.
The accumulator unit has a hydraulic fluid reservoir that holds extra fluid and allows for circulation within the system. It is sized appropriately (e.g., 40-120 gallons) to provide sufficient fluid for BOP operations.
Pressure switches and sensors continuously monitor the hydraulic pressure in the system and can trigger alarms or stop operations if pressure falls below or rises above safe levels.
In remote field operations, solar panels and batteries may be used to power the control systems or pumps, providing energy independence.
All piping and hosing in the system are rated for high pressures (typically over 3,000 psi) to safely transport hydraulic fluid to the BOP.
This is the system’s brain, managing the engines, pumps, and safety functions. It ensures proper sequencing, operation, and emergency shutdowns if needed.
Diesel engines, like the Hatz 1B50E/1D90E or other equivalents, provide the power to drive the hydraulic pumps. These are often paired for redundancy in critical operations.
Bleed-Off Valves: Secondary valves to safely release hydraulic pressure when needed.
Depending on the setup, the accumulator system can be mounted on trailers (for mobility) or skids (for stationary use), with structural supports to house all the components.
Each of these components works together to ensure the accumulator can store hydraulic energy and quickly release it to operate the BOP when needed, maintaining control of well pressure and preventing blowouts.
