BOP Overview

A blowout preventer (BOP) is a large specialized valve used to seal, control and monitor oil and gas wells. The blowout preventer control system (BOP) was developed to cope with the extremely unstable pressure and uncontrolled flow (formation shock) emanating from the well reservoir during drilling. A kick can lead to a potentially catastrophic event called a blowout. In addition to controlling downhole (which occurs in the borehole) pressure and oil and gas flow, blowout preventer control systems (BOP) are designed to prevent tubing (such as drill pipe and well casing), tools and drilling fluid from being blown away when a blowout threatens, out of a wellbore (also known as a borehole, a hole leading to a reservoir). Blowout Preventer Control Systems (BOP's) are critical to the safety of the crew, the rig (system of equipment used to drill the wellbore) and the environment, as well as the monitoring and maintenance of well integrity; therefore, BOP's are designed to become a fail-safe device. (Blowout Preventer Control System BOP, Oil and Gas Industry.
The term BOP (an acronym rather than a colloquial acronym, pronounced BOP rather than "bop") is used in oilfield vernacular to refer to blowout preventers. The abbreviation "BOP" usually begins with the type (e.g. Ram BOP) and is used to refer to a single BOP unit. A blowout preventer control system (BOP) may also be referred to simply as a type (eg Ram).

Two types of BOPs are the most common: the ram type and the annular type. Both types are frequently used in blowout preventer control systems (BOPs), usually with at least one annular BOP stacked on top of multiple ram BOPs.

Annular blowout preventer

The annular blowout preventer is named for its sealing element - a rubber core ring. Also known as universal BOP, multi-effect BOP or spherical BOP. According to the shape of the rubber core, it can be divided into: conical annular BOP, spherical annular BOP, cylindrical annular BOP;

BOP Control System
►Annular BOP function
1) When there is a pipe string in the well, a rubber core can be used to close the annular space formed by the pipe string and the wellhead;
2) When the well is empty, the wellhead can be fully sealed;
3) In the process of drilling and milling, casing grinding, well logging and salvage of well-falling objects, if overflow or blowout occurs, it can seal the space formed by kelly, cables, wire ropes, tools for handling accidents and the wellhead ;
4) With the cooperation of pressure-reducing and regulating valves or small accumulators, it is possible to forcibly lift and lower 18° butt welded pipe joints without fine buttons;
5) In case of severe overflow or blowout, it is used to cooperate with ram blowout preventer and choke manifold to realize soft shut-in.

Ram Blowout Preventer

The ram blowout preventer uses hydraulic pressure to push the well sealing components—two rams with rubber cores—from the left and right sides to the center of the wellbore to close the wellhead, so it is called the ram blowout preventer.
According to the number of rams, it can be divided into single ram BOP, double ram BOP, triple ram BOP;
According to the function of the ram, it can be divided into full-sealed ram BOP, semi-sealed ram BOP, shear ram BOP, variable diameter ram BOP;
The locking method, it can be divided into manual locking ram BOP, hydraulic locking ram BOP;
According to the side door switch mode, it can be divided into rotary side door ram BOP, linear motion side door ram BOP;

BOP Control System
► Ram blowout preventer function
1) When there is a drilling tool in the well, the annular space at the wellhead can be closed with a semi-sealed ram corresponding to the size of the drilling tool;
2) When there is no drilling tool in the well, the fully-sealed ram can fully seal the wellhead;
3) When the drilling tool in the well needs to be cut off and the wellhead is fully sealed, the shear ram can be used to cut the drilling tool in the well and fully seal the wellhead;
4) The ram of some ram blowout preventers is allowed to bear the load and can be used to hang drilling tools;
5) There are side holes on the shell of the ram blowout preventer, which can be used to throttle and relieve pressure;
6) The ram blowout preventer can be used for long-term well closure;

Choose blowout preventer


The main factors to be considered in selecting a hydraulic blowout preventer combination are well type, formation pressure, casing size, formation fluid type, the technical status of personnel, technological requirements, climate impact, traffic conditions, material supply status, and environmental protection requirements, etc. In short, it should be able to achieve balanced drilling, ensure drilling safety and save drilling costs.
1) pressure level
The working pressure of the hydraulic blowout preventer combination depends on the internal pressure resistance of the casing used, the fracture pressure of the open-hole formation at the casing shoe and the expected maximum wellhead pressure. But it is mainly determined according to the maximum wellhead pressure that the blowout preventer combination is expected to withstand. There are five types of blowout preventer pressure levels: 14MPa, 21 MPa, 35MPa, 70MPa, 105MPa, and 140MPa.
2) diameter
The diameter of the blowout preventer combination depends on the casing size in the design of the wellbore structure, that is, it must be slightly larger than the outer diameter of the connected casing. There are nine kinds of BOP diameters: 180mm, 230mm, 280mm, 346mm, 426mm, 476mm, 528mm, 540mm, and 680mm. Among them, 230mm, 280mm, 346mm, and 540mm are commonly used on site.
3) combination form
The choice of combination form is mainly based on formation pressure, drilling process requirements, drilling tool structure and equipment supporting conditions.
