Parameter of NON-KILL BOP
An essential piece of machinery in the oil and gas sector is the blow out preventer (BOP) system, which is made up of a number of components, including a Ram Blowout Preventer, an Annular Blowout Preventer. a Pulsation dampener, Valves, Soare pants. and a Choke & Kill Manifold, all of which work together to ensure the safety and control of high-pressure wells.
Non-kill operation means the type of operation in which operation is made without open flow and well kill when there is pressure inside well. DYZY18 -14 /21 and DYZY18-21/35 non-kill BOP is a set of device for non-kill operation, and its main function is to control pressure of well head during operation, effectively prevent the accident of blowout, and realize the safe operation.
