Kill manifold is a necessary equipment for controlling overflow and blowout, and implementing pressure control technology for oil and gas wells.
During the drilling process of oil and gas wells, once the drilling fluid in the wellbore is contaminated by the formation fluid, the balance between the static liquid column pressure of the drilling fluid and the formation pressure will be disrupted, leading to overflow and blowout.
When it is necessary to circulate contaminated drilling fluid or pump drilling hydraulic wells with adjusted performance in order to rebuild this balance relationship, but normal circulation cannot be achieved through the drill string, the drilling fluid with adjusted performance can be pumped into the well through the kill manifold to control the pressure of the oil and gas well.
