n: a bottle-shaped steel cylinder located in a blowout preventer control unit to store nitrogen and hydraulic fluid under pressure (usually at 3,(XK)pounds per square inch). The fluid is used to actuate the blowout preventer stack.

n: the assembly of well-control equipment including preventers. spools. valves. and nipples connected to the top of the wellhead.

n: a pipe attached to the blowout preventer stack out of which kick fluids and mud can be pumped to the choke manifold when a blowout preventer is closed in on a kick.

n: A high-pressure pipe leading from an outlet on the BOP stack to the backpressure choke and associated manifold. During well-control operations, the fluid under pressure in the wellbore flows out of the well through the choke line to the choke, reducing th

a drilling and workover pressure control device. A line that attached to the BOP stack and through which kick fluids can be circulated when the BOP is closed.

n: the equipment for transporting and using coiled tubing, including a reel for the coiled tubing, an injector head to push the tubing down the well, a wellhead blowout preventer stack, a power source (usually a diesel engine and hydraulic pumps),and a control console. A unique feature of the unit is that it allows continuous circulation while it is being lowered into the hole. A coiled tubing unit is usually mounted on a trailer or skid.

n: a fitting placed in the blowout preventer stack to provide space between preventers for facilitating stripping operations, to permit attachment of choke and kill lines, and for localizing possible erosion by fluid flow to the spool instead of to the more expensive pieces of equipment.

n: a kind of link with flange or keeper on each , and its inner diameter equals to the drift diameter at least




a section of the BOP that allows side ports for choke and kill lines.

n: a device placed or hung in the casing below the blowout preventer stack to form a pressure-tight seal. Pressure is then applied to the blowout preventer stack to test it for leaks.

n: a kind of tool which is put or hung under the BOP stack unitization and used as wiper seal

a plug placed below the BOP prior to a pressure test.

n: a pipe attached to the blowout preventer stack, into which mud or cement can be pumped to overcome the pressure of a kick. Sometimes used when normal kill procedures (circulating kill fluids down the drill stem) are not sufficient.

v: in drilling, to assemble the blowout preventer stack on the wellhead at the surface.

construct or put together a piece of equipment such as a wellhead.

n: the epuippment which is far away the well head and control the blowout preventer stack directely,consist of pump,energy accumulator,valve,and oil tank

n: the act of removing the riser pipe (marine riser) from its attachment to the subsea blowout preventer stack.
