Top Drive Internal Blowout Preventer (IBOP) can be divided into top drive upper IBOP and top drive lower IBOP. They are a control valve used in conjunction with the top drive system. Usually, the two valves are connected in series with the top drive drilling. on the device. The valve uses a highly reliable metal-to-metal seal that can withstand high pressure from both upper and lower directions. Its working pressure can reach 10,000psi or 15,000psi. If a kick is found, the IBOP on the top drive can be remotely closed, and the IBOP under the top drive can be manually closed. The sliding sleeve mechanism of the top drive is an auxiliary mechanism that controls the opening and closing of the IBOP on the top drive. It cooperates with other mechanisms of the drilling rig and can be operated at any height of the derric driller’s console to control the opening and closing of the IBOP on the top drive, and the cavity of the valve body. All parts and components have undergone special anti-corrosion treatment to prolong the service life.
