n: a perforating gun run into the casing string. Most perforating guns are run into the well through the tubing string. casing hanger n: a circular device with a frictional gripping arrangement of slips and packing rings used to suspend casing from a casinghead in a well.

n: A device installed with shaped charge or bulletfor, used for casing perforating.

a large perforating gun, run into a well without tubing.

n: a perforating gun that consists of a metal strip on which are mounted shaped charges in special capsules. After firing, nothing remains of the gun but debris. See gun-perforate.

n: a perforating gun that consists of a hollow, cylindrical carrier into which are placed shaped charges. On detonation, debris created by the exploded charges falls into the carrier and is retrieved when the gun is pulled out of the hole;however, the gun cannot be re-used. See gun-perforate.

a pipe cut-off tool composed of linear shaped charge that is designed to sever pipe. Works on the same principle as a perforating charge.

n: a perforating gun consisting of a hollow, cylindrical metal tube into which are loaded shaped charges or bullets. On detonation, debris caused by the exploding charges falls into the carrier to be retrieved with the reusable gun.

n: a kind of Shaped - perforating guns

n: 1. a hydraulic device operated by a centrifugal pump used to clean the mud pits, or tanks, and to mix mud components.2. in a perforating gun using shaped charges, a highly penetrating, fast-moving stream of exploded particles that forms a hole in the casing, cement, and formation.

n: To drill soft, unconsolidated, usually shallow formations by eroding the rock below the bit by hydraulic impact loading alone. Though not as common as in the past, a bit may be fitted with asymmetric nozzles, one large and two or more small nozzles. If

n: a fishing tool that fires a shaped charge downhole to break up junk so that it can be retrieved. It is run into the hole on drill pipe and collars.

a shaped charge used in perforating.

n: a fishing tool that uses shaped charges to sever casing, tubing, or drill pipe stuck in the hole. See jet cutoff. Compare chemical cuffer.

n: a kinds of inside cutter to cut the frozen pipe in the hole.

a radial shaped charge (explosive) cutter for pipe.

n: an assembly, including a carrier and shaped charges, that is used in jet perforating.

n: 1.the jet gun comprise of the loader and dynamical shoot. 2.the gun of fluid,using to clear the mud pool or the mud tank.
