Treatment of drilling waste cuttings for water based
mud and oil based mud is one of the applications of GN solids control decanter
centrifuge. In oil & gas drilling industry, decanter centrifuge is
mainly used for
solids control system ( to separate fine solids and recovery of barite) and
drilling
waste cuttings management. When it is used in drilling waste management
system, it works together with vertical cuttings dryer, to separate the fine
solids from the cuttings dryer discharged fluids. Sometimes for water based
cuttings which with high solids content, there is a high G dryer behind the
cuttings dryer and before decanter centrifuge, the purpose is to reduce the
solids content in the fluids and protect the decanter centrifuge and get better
performance.
The decanter centrifuge is installed on top of mud tank or on the
telescopic skid. GN provide standard telescopic skid with handrails, walkways,
stairs and other accessories, the feeding pump is installed on the skid for
convenient transportation.
The decanter centrifuge can not be used directly in
drilling cuttings treatment, because the cuttings are coming from shale shaker of solids
control equipments, the solids content is too high and the solids size is too
big to block the feeding tube of the centrifuge. The function of the vertical
cuttings dryer is to separate the big solids and reduce the solids content, and
recovery over 95% of oil from the waste. Because the screen mesh of the
cuttings dryer is too coarse, most of the fine solids passed through the screen
basket, a high speed decanter centrifuge is necessary for the further
treatment.
Right now GN
solids America has 2 units of GNLW363CG centrifuge in Houston with telescopic
skid for rent. It can be used for either solids control equipments and drilling
waste cuttings treatment in the whole States, welcome to inquiry us.
