Слайд 2Annulus
Annulus n : the space between the drillstring and open hole
or drillstring and cased hole in the wellbore
Слайд 3Bit
Bit n : the cutting element at the bottom of the
drillstring, used for boring through the rock.
Слайд 4Blow out
Blow out n : an uncontrolled flow of formation fluids
into the atmosphere at surface.

Слайд 5BOP
BOP abbr : Blow Out Preventer. A valve installed on
top of the wellhead to control wellbore pressure in the event of a kick.
Слайд 6BHA
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 7Casing
Casing n : large diameter steel pipe which is used to
line the hole during drilling operations.
Слайд 8Cementing
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.
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 9Circulate
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 10Company 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 12Directional drilling
Directional drilling : n the intentional deviation of a wellbore
in order to reach a certain objective some distance from the rig.
Слайд 13Drill 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 14Drill 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 15Filter 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".

Слайд 17Formation
Formation n : a bed or deposit composed throughout of substantially
the same kind of rock to form a lithologic unit.
Слайд 18Formation 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 19Hydrostatic 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.
pressure increases uniformly with the density and depth of the fluid.
Слайд 20Lost 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”.
fractures or highly permeable beds. Also referred to as “lost returns”.
Слайд 21Reservoir
Reservoir n : a subsurface porous permeable formation in which oil
or gas is present.
Слайд 22Shale 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 24Stuck pipe
Stuck pipe n : drillpipe, collars, casing
or tubing which
cannot be pulled
free from the wellbore.
free from the wellbore.
