shale shaker

The market is down, we are supplying
service with lower price, we are waiting for the contract. Another factory is
taking more days off. As the saying goes, the economic crisis is not only your
neighbour lost job, yourself is also being fired. Nowadays more and more
oilfield companies have been suffered hard days. And some may change business,
especially small companies, keep lower and lower price will never last too
long.

GN is mainly target on overseas market,
high quality equipment and reasonable price.  GN Solids Control equipment
have taken lots of drilling site in Middle East, Africa, Russia, America,
Brazil, Australia etc.

GN Solids
Control equipment including: shale shaker, shaker screen, mud cleaner,
desander, desilter, decanter centrifuge, mud agitator, mud
gun, centrifugal pump, screw pump, vertical
cuttings dryer
, screw conveyor, High G drying shaker etc.

Keep focusing on solid liquid separation
equipment, making better solids control equipment, drilling
waste management equipment
for oil drilling projects. For HDD,
environmental industry and so on. And this will be where we can make some differences,
from each and every details. So in the new year, we will still keep focusing on
the main equipment, and change the world.

Keep tune on GN Solids Control, in 2016,
we will have big improvement on shale shaker, decanter centrifuge, and cuttings
dryer. Also we will have our TDU thermal
desperation unit ready, well tested, and probably some early bird client will
use it on field. Looking forward a new challenging year.

More and more strict environmental
protection laws will require more TDU equipment, and GN TDU will be very
flexible, comparing a hug site. As in future, we can expect all waste
management work will be done on site. Not a long trip to a mud pit, and
transferred to a lot of equipment, and pumped from this to there. Find you most
convenient way to meet or discuss with GN Solids Control.

GN solids control has
designed and produced hundreds of  mud
tank system for oil drilling rigs since 2008. We were also invited by some
tenders of ONGC, Oil India etc. oil company for their mud tank system. If you
have requirement for solids control equipments and mud tanks system, pls
contact with GN solids control sales.

Specifications of painting/ coating:

Internal tank with 2 layers of anticorrosive coatings, tank
outside with 3 layers of coatings, sandblast before painting. Two pack Epoxy zinc,
thickness 75 μ  for inside tank,

middle layer) Epoxy hi-build containing anticorrosive pigmentstwice,  thickness 250 μ   , Surface pigmented( top coating) with high
quality light fast PU pigments, thickness 70 μ for outside tank.

Mud tank materials:

Normally we make rectangular
tank for mud tank system,
sometimes we also make cylindrical tanks when rectangular tank is not suited
for the project, for example, limit of space, large volume, cheaper cost. For
rectangular tanks, we can make it open tank top or closed tank top or with
gratings cover. The mud tank dimension is calculated by the required storage
volume, we can make standard 40ft container size tank and customized size
tanks. The body(shell) of the tank is made of 6mm thickness corrugated steel plates, sometimes 8mm as required. The bottom plate is normally
8mm, sometimes 10mm as required. 3 runner oilfield tank skid with 250mm porch
on both sides.

However the above mentioned specs could be varies for different tenders.

The mud tank system also equipped with shale shaker, mud cleaner, vacuum degasser,
decanter centrifuge, cavity pump, mud hopper, centrifugal pump, mud agitator, mud
gun, slurry pump, and also with necessary mud tank accessories, including clean
gate, man hole, guard rails, stairs, walkway, pipelines, valves, flexible hose,
hammer union, mud overflow line, lightings, etc,

As the first and most important
solids control equipment in a complete solids
control system
, the shale shaker is used to separate out the most amount of
solids cuttings from the drilling rig. How to define a good shale shaker? We
have following suggestions:

1. A suitable and adjustable
G-force range. In most cases of solids control systems, the vibration G force
is from 5.0 to 7.1, the larger G force is, the better separation performance
does the shaker serve. But the actual G force is decided by the mud condition,
and the jobsite operator should choose and adjust the G force of the shaker. GN
Solids Control has several models of shale shakers,
including the single deck ones and double deck ones, and for single deck ones,
there are 3 screens and 4 screens available. And all GN shakers’ G force could
be adjusted by changing the positions of the two eccentric block in the 2
vibration motors, the largest G force could reach 7.5G.

2. Stable performance vibration
motors, it is true that the worldly wide international brands have the better
reputation because of the quality. GN Solids Control has a long term
relationship with the Italy Brand OLI for vibration motors. The standard Ex
Standard GN have is EXdIIbt4, while GN also has iEC EX and ATEX EX vibration
motors for option.

3. A strong shaker deck whose
angle could be adjusted. A strongly made structure of shaker deck is to insure
the shale shaker could bear the fierce vibration G force from the motors, while
the adjustable design enables the shaker could be used in different conditions
of drilling mud. When you need the drilling fluid to stay longer on the shale shaker screens, you make the screen
deck to have larger angle. GNZS series screens has deck angle ranging from
minus 1 degree to five degrees

The
solids control system could eliminate the large solid particles within the
drilling mud to reduce the particular solids content so that to guard the
transferring pump which used to transfer the mud back the rig with regard to
reusing. GN just done one set mud solids control system with VFD
decanter centrifuge
for gold mining project in Southeast Okazaki, japan.
This system is a 3 stages separation design model; the equipment configuration
is as beneath:
1 . Shale shaker unit GNZS594E-HB used for coarse strong particle separation.
This shale shaker unit could also be employed as a high G pressure drying
shaker
with variable G force up to 7. 4-panel screen makes a bigger area
for drying the actual drilling mud.
2 . VFD design decanter centrifuge device used for fine solids splitting up.
The first one unit centrifuge goes at a middle speed to eliminate most of the
solids to reduce the particular gravity. The following second system VFD
control centrifuge might run at a high speed to get rid of the ultra fine solids
to make the drilling mud
cleaner
.

3. Screw pump set up to transfer the mud to the centrifuge. Horizontally put in
at the flank of the tank, it helps to tank leading more space for operation
mobility.
4. Mud catching tank
used as sand snare and active mud safe-keeping.
This system is to get rid of the solid particles in the going mud to make the
drilling essential fluids reuse. After the solids currently being removed, the
fluids may be pumped back for recycle and the pump would be
additionally protected as there are less solids particles.
Mud solids control system is very common merchandise and solution that GN
provides. For this purpose, GN might provide separation system intended for oil
drilling, no drill down drilling project and some different industrial solid
and chemical phase separation. For more information, delightful send us email
or even call with no hesitate.

Containerized Dewatering Unit

The coagulation and flocculation unit
(hereinafter referred to as the CFU) is intended to serve as the mobile
unit for centrifuges chemical improvement while the drilling mud cleaning
(extraction of “process water” non-combined solvent and removal of the “drilled
solids, solid and dissolved chemical reagent” solids from the mud by
preliminary chemical treatment of the mud and subsequent phase separation in
the centrifuge).

The GNDU2000 Series 20FT Dewatering Unit
provides a process of chemically enhanced configuration to remove the fine
solids less than 5 microns from the water based drilling fluids. As it known
that traditional solids control equipments like shale
shaker
, desander,desilter,
and decanter
centrifuge
will removes solids upper than 5 microns, for colloidal-size
particles which is less than 5 microns will build up in the drilling mud
system. To maintain the drilling mud properties, the operators have to dilute
the drilling fluids with water, this consumes more water and create more
drilling waste.

The mud to be cleaned is supplied from mud tanks to the
station by the centrifuge feeding pumps. The mixing device (mixer) is installed
inside the CFU. The CFU process equipment perform the mud mixing (dosing) with
chemical reagents in the mixer, then the mud is fed from the CFU to the
centrifuges. Centrate (process water) obtained in the centrifuges returns to
the CFU, and solids contained in the mud are removed by the centrifuge and
transferred into the sludge transporter. Centrate (water) is measured in the
CFU and if its parameters are satisfactory, the station pumps transfer it into
the tank (receiving tank) for the new mud mixing. If results are not
satisfactory, the centrate is pumped into the sludge transporter.

Mud and water are delivered and discharged
from the CFU by flexible hoses. The water supply system shall provide water
flow rate of approximately 3 m3/h for mixing in tanks. Centrate overflow,
centrate output to the storage vessels, centrate output to the control vessel,
water input/output, mud input to cleaning shall be designed with quick-release
couplings DN50 and shall be located in the same port on the CFU outer wall. The
port is covered by cover with padlock. 50 meters of flexible hoses are included
into the scope of delivery. Centrate is fed into the centrifuged water tank by
DN150 pipeline. Pipeline inside the CFU is made of constructional carbon steel.
Flange and gooseneck outside the CFU is made of constructional steel and
intended for centrate feeding from two centrifuges. The flexible hose DN150
delivers centrate. 10 meters of flexible hoses are included into the scope of
delivery. All quick-release couplings, flanges, bolts, goosenecks shall be
included into the scope of delivery also.
