A drilling stabilizer is a piece of downhole equipment
used in the bottom hole assembly (BHA) of a drill
string. It mechanically stabilizes the BHA in the
borehole in order to avoid unintentional sidetracking,
vibrations, and ensure the quality of the hole being
drilled.
It is composed of a hollow cylindrical body and
stabilizing blades, both made of high-strength steel.
The blades can be either straight or spiralled, and are
hardfaced for wear resistance.
Several types of drilling stabilizers are used in the
oilfield today. While integral stabilizers (fully
machined out of a single piece of steel) tend to be the
norm, other types can be used, such as :
Replaceable sleeve stabilizer, where the blades are
located on a sleeve, which is then screwed on the body.
This type can be economical when no repair facilities
are available close to the well being drilled and air
freight has to be used.
Welded blades stabilizer, where blades are welded onto
the body. This type is usually not advised on oil wells
due to the risks of losing blades, but is regularly
used when drilling water wells or on low-cost
oilfields.
Usually 2 to 3 stabilizers are fitted into the BHA,
including one just above the drill bit (near-bit
stabilizer) and one or two among the drill collars
(string stabilizers).
