a perforating process involving pumping a slurry of liquid and size particles through a nozzle to cut through steel and rock.

n: 1.the injection of air into a reservoir in a pressure maintenance or an in situ combustion project. 2. the injection of fuel into the combustion chamber of a diesel engine by means of a jet of compressed air.

n: The Process that keeping downhole cleaning and improving drilling efficiency by jet flow of drilling fluid pounding the cuttings in the downhole in the drilling programe.

n: a vessel used to bury a pipeline beneath the seafloor. The barge moves forward by means of anchors. A jet sled is lowered over the pipeline;as the barge pulls it over the pipe, high-pressure jets of water remove soil from beneath the pipe, allowing the pipe to fall into the jetted-out trench.

n: trade name for appratus for cleaning and freeing oil tanks of gas by means of high-pressure jets of hot water. It consistes essentially of opposed double nozzles, which rotate slowly about their horizontal and vertical axes and project two streams of hot water at a pressure of 175 psi (1,206 kilo pascals) against all inside surfaces of the deck, bulkheads, and shell plating.

n: No metal clast left in the wellbore to block the formation after perforation by modified jet perforating explosive charge.

n: The pressure of fluid decreases below saturated vapor pressure and forms jet with numbers of air bubble when the fluid passes through special nozzle. The air bubble forms domestic high pressure when striking the solid border.

n: A conical flaring device for cementing. The cement slurry is formed by throwing into hopper due to hydraulic jet.

n: a method of severing steel pipe in a well by applying high-pressure jets of a very corrosive substance against the wall of the pipe. The resulting cut is very smooth.
