BOP Summary

Product Description

Our company produces blowout preventers and hydraulic control systems, which can meet the purposes of
well drilling, underbalanced drilling, underground operation, non-killing we* pressurized operations, etc. with a
full range of specifications, bore sizes fromΦ52-Φ540 (2 1/16in-21 1/4in), pressure rating from 7Mpa to 105Mpa
(1000psi-15000psi). The H2S resistance performance complies with NACE MR-0175:2003 requirements. It is
applied to oil extraction, perforation, test, operation, pressurized operation and underbalanced drilling. 

Principle:

when the oil gas pressure within the well is pretty high,the blowout preventer can dose the well (tightly closing) .When the heavy mud is entered from the inner pressure of the drilling rod, there arc four channels under the blowout preventer of the shutter, which can replace the mud suffered from gas invasion and enhance the liquid control pressure within the well to pressurize the Injection of the oil gas.

Application:

the blowout preventer is divided into the common blowout
preventer, ring blowout preventer and rotary blowout preventer,among which, the common blowout preventer includes the scaling shutter and semi-sealing shutter type. The sealing
shutter can seal the whole well port while the semi-sealing shutter only seal the ring section of well port with drilling rod. Ring (universal) blowout preventer Is started in emergency circumstances and it is able to deal with the drilling tool and well; rotary blowout preventer can conduct the edge blowout operation.

Function:

 The well port shall be closed during the process of drilling,oil trial,well repair and well operation, so as to be preventive form well injection, which, as a result, protects the equipment and protect the safety of the working personnel.
