n: a perforating gun that consists of a metallic strip OIl which encapsulated shaped charges are mounted. After the gun is fired, the strip is retrieved. See gun-perforate.

n: There has a metal ribben belt in the gun perforator,the belt can recovery after be used.

n: a floating offshore drilling unit that has pontoons and columns that, when flooded. cause the unit to submerge to a predetermined depth. Living quarters, storage space, and so forth are assembled on the deck. Semisutxnersible rigs are self-propelled or towed to a drilling site and anchored or dynamically positioned over the site, or both. In shallow water, some semi-submersibles can be ballasted to rest on the seabed. Semi-submersibles ale more stable than drill ships and ship-shaped barges and are used extensively to drill wildcat wells in rough waters such as the North Sea. Two types of semi-submersible rigs ale the bottle- type and the column-stabilized. See floating offshore drilling rig.

n: the person under HAZWOPER who responds to an emergency and is the individual in charge of the ICS. As such. he or she is responsible for coordinating and controlling all emergency responders and their communications.

n: a one-piece orifice fitting that allows the orifice plate in it to be changed without depressuring the meter run or shutting off the flow of gas.

n: the part of a measuring device that is responsive to the absolute value or change in a physical quantity, such as temperature, pressure flow rate, pH, light, or sound. It converts that change into an input signal for an information-gathering system.

n: A kind of special cement slurry that be used in ultra-deep well,in which be feeded extender firstly,then be feeded accelerating chemicals .

n: the process of removing gas from liquid and liquid from gas.

processes related to separation of gas, water and hydrocarbons.

n: a metal sleeve that shuts off tubing-to-annulus flow if a packers sliding sleeve fails. See also sliding sleeve.

n: a cylindrical or spherical vessel used to isolate the components in mixed streams of fluids. See oil and gas separator.

a production treating vessel designed to facilitate the separation of gas, oil, and/or water from a produced fluid stream
