Before You Buy a Blowout Preventer

Before you buy a blowout preventer, you’ll need to know exactly what kind you’re looking for. There are different types of BOPs to choose from and you’ll need to decide how quickly you need it.

Let’s take a look at the different types of BOPs and the advantages of aftermarket parts.

Understanding Different Types of BOPs

Annular blowout preventers are installed on top of other BOPs to allow sealing and control of the oil well. If no drill pipe or other BOPs have been installed yet, the annular BOP will be placed on the opening of the well itself.

A ram blowout preventerram blowout preventer functions like a gate valve at the top of a BOP stack on an oil well, regulating the flow of oil and sealing off the well when necessary. The seal is achieved through a pair of steel plungers that pull inward to restrict flow and press outward to allow the oil to flow freely.

How Quickly You Need the Equipment

When it comes to buying a BOP, you get to decide when you need them. Some orders might need to be handled faster than others for certain applications. Whether you need a BOP for a long-term project or for immediate needs, new or used parts and equipment are readily available for your industry.

Pro Tip: You can rent a wide range of new and used blowout preventer products from B.O.P Products, a trusted BOP provider. 

Advantages of Aftermarket BOPs

Aftermarket BOPs are virtually always less expensive than their name-brand counterparts. They’re also easier to find through a wide variety of dealers located in far more convenient locations. Additionally, many aftermarket providers offer guarantees for their products as an added incentive.

Conclusion

Do your research before you buy a blowout preventer and speak with a knowledgeable expert to find the right solutions for your company.

Ram BOPs are indispensable safety devices in the oil and gas drilling industry. Safety is of utmost importance in the modern oil and gas drilling industry, whether in drilling and maintenance operations or in natural gas production. Such as Ram BOPs, are crucial equipment for ensuring the safety of personnel and equipment. Today, Sino Mechanical would like to discuss the functions, working principles, types, and prices of Ram BOPs with you, with the aim of assisting customers in selecting the appropriate blowout preventer system.

1. Functions and Importance

Ram BOPs serve critical functions in drilling operations, with their primary roles including:

Blowout Prevention: During drilling and well servicing operations, Ram BOPs are the first line of defense against uncontrolled releases of oil or gas from the well. They can rapidly close and seal the wellbore to prevent blowouts.

Pressure Control at the Wellhead: Ram BOPs maintain wellhead pressure within a controllable range, ensuring the safety of personnel and equipment. They can quickly close off the well to contain pressure buildup.

Safety Assurance: Ram BOPs significantly reduce the risk of accidents and environmental incidents, protecting both human lives and the environment.

2. Ram BOP Working Principles

The working principles of Ram BOPs are based on their internal ram assemblies. When there is an unexpected surge in wellhead pressure, these rams move horizontally or vertically to block the wellbore, effectively sealing it. The operation of these rams is controlled by hydraulic or pneumatic systems, allowing for rapid responses to pressure changes.

3. Ram BOP Types

Ram BOPs come in various types, each with its unique characteristics:

Annular Ram BOPs: These BOPs have a flexible sealing element that can adapt to different wellbore sizes, providing a versatile solution for sealing the wellbore.

Blind Ram BOPs: Blind Ram BOPs are used to close off and seal the wellbore completely. They are effective when there are no drill pipes or tools in the well.

Pipe Ram BOPs: Pipe Ram BOPs are designed to seal around the drill pipe, making them suitable for operations involving pipe and casing.

4. Ram BOP Prices

The pricing of Ram BOPs varies depending on factors such as the model, specifications, and supplier. Standard models typically range from several thousand to tens of thousands of dollars, while customized solutions may have higher costs. Prices are influenced by market demand, raw material costs, and manufacturing processes.

When applying blowout preventers on-site, multiple combinations are used as needed. Typically, the upper section consists of a universal blowout preventer, the middle section has a variable bore gate valve blowout preventer, and the lower section includes shear gate valve blowout preventers, among others. Various combinations of blowout preventers are used based on the specific requirements of the site. The collective term for these various combinations of blowout preventers is referred to as a Blowout Preventer Assembly (BOP).

6.Selection of BOP Stacks

Factors to consider when selecting a hydraulic blowout preventer assembly include the well type, formation pressure, casing size, formation fluid type, personnel expertise, process technology requirements, climate impact, transportation conditions, material supply status, and environmental protection requirements, among others. In summary, the assembly should facilitate balanced drilling, ensure drilling safety, and save drilling costs.

Selection of Pressure Rating

The working pressure of a hydraulic blowout preventer assembly depends on factors such as the internal pressure resistance of the casing used, the formation fracture pressure at the casing shoe, and the anticipated maximum wellhead pressure. However, it primarily depends on the anticipated maximum wellhead pressure the blowout preventer assembly is expected to withstand. Blowout preventer pressure ratings come in five categories: 14 MPa, 21 MPa, 35 MPa, 70 MPa, 105 MPa, and 140 MPa.

Selection of Bore Diameter

The bore diameter of the blowout preventer assembly depends on the casing size in the wellbore structure design and must be slightly larger than the outer diameter of the connected casing. Blowout preventer bore diameters are available in nine sizes: 180mm, 230mm, 280mm, 346mm, 426mm, 476mm, 528mm, 540mm, and 680mm. Among these, commonly used sizes in the field are 230mm, 280mm, 346mm, and 540mm.

Selection of Combination Configuration

The choice of combination configuration is primarily based on formation pressure, drilling process requirements, drilling tool structure, and equipment compatibility.

In conclusion, Ram BOPs play a pivotal role in ensuring the safety and success of drilling operations in the oil and gas industry. Understanding their functions, working principles, types, and prices is essential for making informed decisions and ensuring the safety of both personnel and the environment during drilling operations.
