AnnulusAnnulus n : the space between the drillstring and open hole or drillstring and cased hole in the wellbore
Слайд 3
Bit
Bit n : the cutting element at the
bottom of the drillstring, used for boring through the
rock.
Слайд 4
Blow out
Blow out n : an uncontrolled flow
of formation fluids into the atmosphere at surface.
See video
Слайд 5
BOP
BOP abbr : Blow Out Preventer. A
valve installed on top of the wellhead to control
wellbore pressure in the event of a kick.
Слайд 6
BHA
Bottom hole assembly (BHA) n : the part
of the drillstring which is just above the bit
and below the drillpipe. It usually consists of drill collars, stabilisers and various other components.
Слайд 7
Casing
Casing n : large diameter steel pipe which
is used to line the hole during drilling operations.
Слайд 8
Cementing
Cementing v : the placement of a liquid
slurry of cement and water inside or outside
of the
casing. Primary cementing is carried out immediately after the casing is run.Secondary cementing is carried out when remedial work is required.
Слайд 9
Circulate
Circulate v : to pump drilling fluid through
the drill string and wellbore, returning to the mud
pits. This operation is carried out during drilling and is also used to improve the condition of the mud while drilling is suspended.
Слайд 10
Company man
Company man n : an employee of
an operating company whose job is to represent the
operator's interests on the drilling rig (sometimes referred to as "drilling supervisor" or "company man").
Слайд 12
Directional drilling
Directional drilling : n the intentional deviation
of a wellbore in order to reach a certain
objective some distance from the rig.
Слайд 13
Drill collar
Drill collar n : a heavy, thick-walled
steel tube which provides weight on the bit to
achieve penetration. A number of drill collars may be used between the bit and the drillpipe.
Слайд 14
Drill pipe
Drill pipe n : a heavy seamless
pipe which is used to rotate the bit and
circulate the drilling fluid. Lengths of drill pipe 30ft long are coupled together with tool joints to make the drillstring.
Слайд 15
Filter cake
Filter cake n : the layer of
concentrated solids from the drilling mud that forms during
natural filtration on the sides of the borehole. Sometimes called "wall cake" or "mud cake".Watch the video
Слайд 16
Fishing
Fishing v : the process by which a
fish is removed from the wellbore.
Watch the video
Слайд 17
Formation
Formation n : a bed or deposit composed
throughout of substantially the same kind of rock to
form a lithologic unit.
Слайд 18
Formation pressure
Formation pressure n : the pressure exerted
by the formation fluids at a particular point in
the formation. Sometimes called "reservoir pressure" or "pore pressure".
Слайд 19
Hydrostatic pressure
Hydrostatic pressure n : the load exerted
by a column of fluid at rest. Hydrostatic
pressure
increases uniformly with the density and depth of the fluid.
Слайд 20
Lost circulation
Lost circulation n : the loss of
quantities of whole mud to a formation due to
caverns,fractures or highly permeable beds. Also referred to as “lost returns”.
Слайд 21
Reservoir
Reservoir n : a subsurface porous permeable formation
in which oil or gas is present.
Слайд 22
Shale shaker
Shale shaker n : a series of
trays with vibrating screens which allow the mud to
pass through but retain the cuttings. The mesh must be chosen carefully to match the size of the solids in the mud.
Слайд 24
Stuck pipe
Stuck pipe n : drillpipe, collars, casing
