CENTER DRILLING [13 records]

Record 1 2021-07-14

English

Subject field(s)
  • Oil Drilling
CONT

Horizontal hydraulic fracturing is accomplished by drilling vertically to the depth of the shale formation, which is generally found between 0. 6 – 1. 5 km below the surface. When the gas-containing shale is intercepted, the drill bit is maneuvered to travel horizontally through the center of the formation for a distance of up to 1. 6km. Water, biocides, surfactants, sands, and other chemicals are forced into the borehole under extremely high pressure to induce fractures in the shale that allow gas to rise to the surface for collection...

OBS

The terms "fraccing" and "fracing," short for "fracturing," are pronounced "fracking."

Key term(s)
  • horizontal hydro fracking
  • horizontal hydro-fracking

French

Domaine(s)
  • Forage des puits de pétrole
DEF

Processus qui consiste à créer de multiples fractures le long du segment horizontal d'un puits de forage afin d'en augmenter la perméabilité et de permettre au gaz de s'échapper.

English

Subject field(s)
  • Milling (Machine-Tooling)
  • Boring (Machine-Tooling)
  • Machine-Tooling (Metallurgy)
CONT

[In an] example of why the horizontal type of boring and milling machine is becoming known as a machining center... a gear-shaper housing is completely machined on a tape-controlled Jigmil. The operations include face milling, tee-slot milling, drilling, tapping, and boring.

OBS

milling and boring machine In the case of machines having a milling-machine configuration, especially one of a vertical milling machine, this term is used exclusively.

French

Domaine(s)
  • Fraisage (Usinage)
  • Alésage (Usinage)
  • Usinage (Métallurgie)
CONT

Les aléseuses modernes (aléseuses-fraiseuses) permettent tous travaux d'alésage (finition de trous ébauchés) mais ce sont également des perceuses, des fileteuses et des fraiseuses universelles.

OBS

«Fraiseuse-aléseuse», contrairement à «aléseuse-fraiseuse», peut désigner des machines de moyenne ou de petite capacité ayant la forme de fraiseuse (cf. MACOU 1975, 320, p. 153) ou de machine d'outillage (cf. MACMO 1977, 820, p. 79).

OBS

fraiseuse-aléseuse : Les deux expressions «aléseuses-fraiseuses» et «fraiseuses-aléseuses» sont utilisées. Toutefois, la dernière dénomination sera de préférence utilisée lorsque la broche est montée dans un bras, un fourreau cylindrique ou un coulant prismatique à axe horizontal, traversant le chariot [...]

Record 3 2011-07-20

English

Subject field(s)
  • Equipment (Oil and Natural Gas Extraction)
  • Winches
DEF

The hoisting mechanism on a drilling rig. It is essentially a large winch that spools off or takes in the drilling line and thus raises or lowers the drill stem and bit.

DEF

Nerve center of the drilling rig; principal parts include hoisting drum, brakes, clutches, catheads, and control panel...

CONT

On a drilling rig, the hoist that raises and lowers the drill stem is called "drawworks."

Key term(s)
  • draw-works

Domaine(s)
  • Outillage (Extraction du pétrole et du gaz)
  • Treuils
DEF

Record 4 2007-08-28

English

Subject field(s)
  • Maneuvering of Ships
  • Oil Drilling
DEF

A system of mooring a drill ship on the drilling site in which mooring lines are spooled onto winches mounted on a turret in the center of the vessel.

OBS

Because all mooring lines are connected to the turret, the vessel is free to rotate around the turret axis and head into oncoming seas, regardless of the direction.

Record 5 2003-09-11

English

Subject field(s)
  • Oil Drilling
  • Equipment (Oil and Natural Gas Extraction)
DEF

A walled, round hole or well in the hull of a drill ship(usually in the center) through which the drilling and other assemblies pass while a well is being drilled, completed, or abandoned from the drill ship.

CONT

Unlike traditional vessels, [drill vessels] are modified by a center opening through the vessel for conducting drilling operations. This center opening is commonly called a "moonpool. "

CONT

Most of the development of equipment and technology for rotary drilling from floating vessels started with an extensive shallow-hole coring operation off the coast of California in the Santa Barbara Channel. The very first operations were conducted "over the side" of the drill vessel, but these were quickly supplanted by vessels designed with a center drill well or "moonpool. "

CONT

The center drill well is located with the center of gravity of the vessel to minimize the effect of rotational motion. The derrick or mast is located over the drill well with the pipe racks adjacent either fore or aft.

Key term(s)
  • moon-pool

French

Domaine(s)
  • Forage des puits de pétrole
  • Outillage (Extraction du pétrole et du gaz)
DEF

Ouverture pratiquée dans la coque d'un navire de forage ou dans le plancher d'une plate-forme pour donner passage aux équipements de forage.

CONT

Une ouverture de 5 m de diamètre, ou plus, au centre de la plate-forme ou de la coque du bateau permet l'immersion des équipements sous-marins, assemblés, essayés sur un pont particulier [...]. Cette ouverture appelée «slot» ou «moonpool» est traversée par deux poutres horizontales rétractables servant de support des ensembles avant immersion. (Forages, no54, janvier - mars 1972, p. 40).

OBS

Moonpool est réservé à une ouverture centrale. Slot s'emploie quand cet espace est aménagé dans l'un des côtés de la plate-forme (notamment sur les plates-formes triangulaires). Cet orifice est généralement rectangulaire, mais sur les premières unités de forage (navires, barges), il était circulaire, d'où, probablement, son appellation.

OBS

Il n'y a pas d'équivalent français attesté. Nous proposerions : la porte, si ce mot ne désignait pas déjà une autre réalité (ouverture aménagée dans un côté du derrick). On pourrait dire : la trappe, la piscine, la lucarne ...

Subject field(s)
  • Shipbuilding
  • Fluid Mechanics and Hydraulics (Physics)
  • Pleasure Boating and Yachting
  • Equipment (Oil and Natural Gas Extraction)
DEF

The center of gravity of the fluid displaced by a floating body(as a ship or mobile, offshore drilling rig).

DEF

A point through which passes the resultant of all upward forces and by which a floating ship is supported.

CONT

For monohulls, there are two generic forms for these curves, depending roughly on whether the centre of gravity is above or below the centre of buoyancy.

CONT

In vessels of ordinary form it is found that the distance of the center of buoyancy below the load waterline varies from 8/20 to 9/20 of the mean draft to top of keel.

OBS

centre of buoyancy; centre of displacement: terms officially approved by the Naval Terminology Standardization Committee.

Domaine(s)

  • Mécanique des fluides et hydraulique (Physique)
  • Yachting et navigation de plaisance
  • Outillage (Extraction du pétrole et du gaz)
DEF

Centre de gravité du liquide déplacé par le volume immergé.

CONT

En fait, le centre de carène théorique (c.c.) situé au centre de la partie immergée de la coque lorsque le bateau au repos flotte à plat, se déplace vers l'extérieur chaque fois qu'une nouvelle section s'immerge à la gîte et supporte le poids.

CONT

Théoriquement, la force de pesanteur s'exerce en un point appelé centre de gravité (CG) et la force de poussée en un autre point ou centre de poussée (CP). [...] En cas de gîte, le CP descend en suivant l'inclinaison et sa verticale se déplace du CG.

CONT

À chaque angle d'inclinaison il se forme un couple de redressement formé d'un côté par le poids du bateau agissant au centre de gravité et de l'autre par la poussée hydrostatique (égale au déplacement) et agissant au centre du volume immergé ou centre de carène.

CONT

La résultante des pressions hydrostatiques s'exerçant sur la carène d'un navire immobile est une poussée verticale, dirigée vers le haut, égale au déplacement et appliquée au centre de carène (principe d'Archimède).

OBS

centre de carène; centre de poussée : termes uniformisés par le Comité de normalisation de la terminologie navale.
