Description
Rotary BOP device:
1. Equipment usage
The equipment is a rotary deflector, that is, to guide the fluid returned from the parallel barrel away from the drill floor, establish the shielding between the annulus and the drill floor, and bear certain pressure, so as to realize the purpose of underbalanced drilling. It can be widely used in negative pressure drilling, natural gas and air drilling, workover operation and normal drilling. It can effectively reduce drilling cost, reduce mud damage to formation, increase oil well production and achieve the effect of environmental protection drilling.
2. Product development
Rotary BOP, also known as rotary control head, is an indispensable key equipment for underbalanced drilling technology. With the increasingly strict requirements of environmental protection drilling, the equipment will also be used in the field of normal drilling. The rotary control head is installed on the top of annular BOP or ram blowout preventer, which is used to seal the rotary drilling tool and play a diverting role in realizing underbalanced drilling technology and other pressurized drilling operations. It can be used for drilling with pressure and tripping without killing after matching with hydraulic BOP, check valve of drilling tool, gas separator and snubbing pressure device. It plays an important role in special operations such as releasing low pressure oil and gas reservoir, leak proof drilling, aerated drilling, snubbing and workover. At present, most of the rotary blowout preventers used in domestic oil fields are imported products, which are expensive. In order to promote the large-scale application of underbalanced drilling technology in China and meet the drilling requirements of different oilfield areas, our company has jointly developed a series of rotary blowout preventers (double rubber core rotary head and single rubber core rotary head) jointly with Sinopec Zhongyuan Oilfield. The new fxb20 / 35-17.5/35 rotary BOP can pass through 51 / 2 Drilling tools (this type of equipment has always been a monopoly product of foreign countries, only leased to the Chinese market, not sold, resulting in high operating costs in China's domestic oilfields. When competing for the third bid abroad, it was often led by foreign companies because of its high price). The birth of this type of equipment filled in the domestic blank, thus obtained the patent right, and made due contributions to China's oilfield industry.

Rotary BOP
Rotary BOP is a well control device used for underbalanced drilling (underbalanced drilling), which provides safe and effective pressure control for drilling under pressure and snubbing and guides annulus fluid into the surface control system to achieve underbalanced drilling.
There are two types of rotary BOP: single rubber element and double rubber element.
The Role of Rotary BOPs in Underbalanced Drilling
The Rotary BOP, also known as a rotating blowout preventer or rotating control device, is a critical component in underbalanced drilling operations. It guides returned fluid away from the drill floor, shielding it and maintaining pressure, thus enabling underbalanced drilling while reducing costs and environmental impact. Developed for underbalanced drilling, it's now used in various drilling operations, including workover and natural gas drilling. Our company, in collaboration with Sinopec Zhongyuan Oilfield, has developed a series of rotary blowout preventers to meet diverse drilling needs. Rongsheng BOPs offer a cost-effective alternative to imported products, contributing to the advancement of China's oilfield industry. With robust construction and versatile design, our Rotary BOPs ensure efficient drilling operations, making them suitable for various drilling rigs and applications.
Introducing the Cangzhou Fengliang Petroleum Machinery Co.,Ltd Rotating Control Device (RCD)
The Rotating Control Device (RCD) by Rongsheng stands as a paramount component in well control operations, serving as a cornerstone in both onshore and offshore drilling environments. Specifically engineered for underbalanced drilling (UBD), managed pressure drilling (MPD), and other high-pressure drilling methods, our RCD ensures optimal safety and efficiency during critical drilling operations.
Installed atop an annular blowout preventer (BOP) or ram BOP, the Fengliang Rotating Control Device is designed to seal around the rotating drill pipe, providing a secure barrier to divert drilling fluid away from the rig floor. This essential function enhances operational safety and minimizes the risk of blowouts or fluid-related incidents.
Operating on a principle driven by the top drive or Kelly from the driving bushing assembly, our RCD features a rotating sleeve center pipe and rubber seal element, ensuring a positive seal on the drill pipe or Kelly. With options for dual or single stripper rubber elements, our RCD system adapts to various drilling conditions and pressure requirements, offering versatility and reliability in challenging drilling environments.
Compliant with API 16RCD standards, the Fengliang Rotating Control Device is meticulously engineered and manufactured to meet the highest industry standards. Widely adopted by leading global service companies and oil operators, including CNPC, Sinopec, CNNOc, and Shell, our RCD systems have earned a reputation for excellence in performance and reliability.
With a range of sizes and operating pressures available, the Fengliang Rotating Control Device offers flexibility and adaptability to suit diverse drilling applications. Our compact design ensures easy integration under most drilling rigs without the need for extensive modifications, enabling faster rig-up times and enhanced maneuverability on-site.
Trust Fengliang for innovative solutions in well control equipment, and experience the difference in performance, reliability, and safety with our Rotating Control Device systems.
