In the oil and gas industry, a leaky well could spell disaster. Not only will repairs cost the company money, but the spilled oil is dangerous to workers and wildlife alike. Fortunately, helpful devices known as blowout preventers prevent this disaster from happening.
Simply put, blowout preventers (BOPs) keep the oil well safely sealed to prevent damages and revenue loss. Various types of BOPs serve slightly different purposes and may help with a certain type of oil well problem more than another. Before you decide which type you need, you must first understand what each type does. A blowout preventer for your oil well will make a huge difference.
BOPs play a crucial role in oil drilling. While most individuals understand what the basic functions of this device, that is not enough. There is a need to understand each component of BOPs, their individual functions and how they work together in order for increased safety and efficiency. Taking a look at the basic components of every BOP.
Accumulator: The accumulator is the main control unit of a blowout preventer. It is responsible for the control of all systems that interconnect in preventing emergency situations. It is activated based on hydraulic pressure. The accumulator houses hydraulic reservoirs, control valves, pumps, control manifold, and compressed gas bottles among other features.
An accumulator is usually mounted on the top of the BOP stack. This helps to avoid breakdown, as the accumulator provides power for other BOP units to run during system failures.
Annular BOP: The annular BOP is responsible for closing the space around the drill pipe. It does this by controlling the air flow to prevent mud, without affecting the operation of the system. It is effective in maintaining a seal around the drill pipe during the process of drilling. Annular BOP is on top of the stack other BOPs to ensure efficient airflow control.
RAM BOP: The basic function of the Ram BOP is to prevent unwanted materials from exploding in the system during drilling. Several Ram BOPs perform other functions to ensure safety. Some of them are:
– Blind RAMs: This RAM closes over any portion, without a drill string.
– Choke Manifolds: This is a system of pressure sensors which control the flow of fluids in various directions.
– Kill Line Valve: This acts as a backup to the standard drill pipe.
– Choke Line Valve: It directs mud to the choke manifold in the case of a kick.
All of these components work together to ensure ease and safety of drilling. BOPs are built in different capacities for different drilling requirements. Some are used for land wells, others for offshore rigs, and a third-class for subsea wells. In conclusion, BOP control is very important in avoiding breakdown of the system. There are about five control measures with ROVs intervention being the most deployed. However, the drilling purposes will inform the BOP control methods that are best for each preventer.
Guangzhou Dongsu Petroleum D&E Equipment Co., Ltd. is one of the earliest professional manufacturers of surface-mounted BOP control system in China. Since the early 1980s, The company is committed to the development, design, research and development of surface mounted BOP Control System, Pneumatic Pressure Test Unit, Choke Manifold Control Panel，etc. In 2017, we established a technical service training center integrating after-sales training, maintenance, testing and transformation to provide high-quality and efficient services.
