Blowout preventer is used to close the wellhead during oil testing, well repair, and completion operations to prevent blowout accidents. It combines the functions of full sealing and semi sealing, and has the characteristics of simple structure, easy operation, and high pressure resistance. It is a commonly used safety sealing wellhead device in oil fields to prevent blowout.
During oil drilling, a blowout device installed on the wellhead casing head is used to control high-pressure oil, gas, and water. When the oil and gas pressure in the well is very high, the blowout preventer can seal (shut off) the wellhead. When heavy mud is pressed into the drill pipe, there is a four-way valve under its gate, which can replace the mud that has been invaded by gas, increase the pressure of the liquid column in the well, and suppress the high-pressure oil and gas injection.
It is classified into ordinary blowout preventers, universal blowout preventers, and rotary blowout preventers. A universal blowout preventer can be activated in emergency situations to handle drilling tools and empty wells of any size; Rotating blowout preventers can achieve simultaneous spraying and drilling operations. In deep well drilling, in addition to the two types of ordinary blowout preventers, a universal blowout preventer and a rotary blowout preventer are often added, so that three or four types of combinations are installed at the wellhead.
Wellhead blowout preventer group: annular blowout preventer, ram blowout preventer, four-way, etc.
Common classification of blowout preventers:
Hydraulic blowouts mainly come in two forms: ram blowouts and annular blowouts.
The ram of the ram blowout preventer can be divided into four types: fully sealed, semi sealed, variable diameter, and shear.
The type of annular blowout preventer can be divided into conical annular blowout preventer and spherical annular blowout preventer according to the shape of its sealing core.
Product Parameters
Annular BOP is an important part of the well control devices. It is mainly used to control the wellhead pressure in the drilling, well work over and oil testing, effectively preventing from the blowout accident sand working in safety.
Annular BOP can only be used when equipped with BOP hydraulic control device, it is usually used with ram BOP or separately. Sealing element has spherical and conical type.

Rotating blowout preventers are necessary equipment for underbalanced drilling, geothermal drilling, and coalbed methane drilling. It serves as a barrier between the wellbore annulus and the drill string, providing safe and effective pressure control, while also guiding the wellbore fluid away from the wellhead. The development of this technology has expanded the scope of use of underbalanced drilling technology, such as in closed loop circulation, drilling while spraying, measurement while drilling, wellbore testing, reverse circulation, and nitrogen injection when drilling characteristics change. The rotary blowout preventer mainly consists of a rotating assembly, a shell, a buckle cylinder, etc. The rotating assembly mainly consists of a square tile assembly, a central tube, bearings, seals, rubber cores, etc

Company Profile
SHANDONG BEYOND PETROLEUM EQUIPMENT CO.,LTD. is established on request of client and aimed to supply best product and service for the client. It focuses on to supply best solutions for the overseas oilfield customer on equipment & spares maintenance and supply.
China has become main supplier for oil production countries, but Chinese equipment has some special features different with European and American countries, and there exits big language and cultural difference between China and other countries, so it has become one big challenge for the overseas client to get the exact equipment and parts they need in a short time.
However, BEYOND takes root in China, and has very good cooperation relationship with most of famous factories, plus strong technical support and good advantage in language. Therefore, BEYOND is quite capable to help the customer to solve this challenge.
BEYOND products cover but not limited to: China-make oil drilling rigs, workover rigs, wellhead and downhole tools, drilling tools, OCTG and other related equipment and parts.
Meanwhile, BEYOND can offer technical services, personnel training and maintenance guide towards China-made drilling rigs. Only if it is what you need, BEYOND can get it for you: from best factories, with most competitive price and within shortest lead time.
With "Professional&Efficient, Customer Focus, Win-win Cooperation" as its operation principle, BEYOND believes that it will become your best cooperative partner in China.
