Petroleum is an important strategic resource. In the process of oil exploration, it is not that simple. Today we will share with you an indispensable machine, blowout preventer, during downhole operations.

The phenomenon of "blowout" is not unfamiliar. After all, there are texts about this aspect in the textbooks of elementary school, and the deeds of Wang Jinxi and others are vividly vivid.

The blowout preventer is used to prevent blowout. Let’s learn more about the classification code of the blowout period and so on.

classification

The blowout preventers used today are mainly divided into two types, one is the ram blowout preventer, and the other is the annular blowout preventer. These two types of blowout preventers have their own advantages and disadvantages. Let's introduce them in detail below.

The ram blowout preventer is divided into single ram blowout preventer, double ram blowout preventer and triple ram blowout preventer, in which one pair, two pairs and three pairs of rams are installed to seal different pipe strings and empty wells.

The annular blowout preventer is divided into a single annular blowout preventer and a double annular blowout preventer, in which one annular rubber core and two annular rubber cores are respectively installed.

Briefly understand the classification and code name of blowout preventers, etc.

Codename

The BOP code consists of one letter of the pinyin of the main Chinese character of the BOP name.

Annular blowout preventer is also called multi-effect blowout preventer.

When closing the well, the annular rubber core is evenly squeezed to the center of the wellbore, which has the advantages of high pressure bearing, reliable sealing, convenient operation and rapid opening and closing.

It is especially suitable for sealing pipe strings of various forms and sizes, and can also completely seal wellheads.
