| 摘要 | An emergency wellbore intervention assembly connected to a BOP having a first generally L-shaped gate valve with a first and second port on each end of the L, each side operably connected to an actuator connectable to a hydraulic control line for selectable fluid communication with a pipe, the first port connected to a choke line, and the second port connected above a lower shear ram of a BOP, the first gate valve in selectable fluid communication with the pipe to a second similar two valve assembly operably connected to a kill line and below the lower shear ram and a manually operated valve operably connected to the second gate valve for fluid engagement to a high pressure fluid source. A method for controlling a well using the two valve assemblies by selectively plugging the well and circulating fluid from the kill side to the choke side of the system. | ||||||
