solids control equipment | GN Decanter Centrifuge

6 Sets of GN Decanter Centrifuge and 40 Sets Mud Agitator Delivered to South America Market

GN leads the way in solids control
technology with it new designed decanter centrifuge in
China. As the firstly API certified manufacturer of solids control equipment and
system in China, GN has always been keeping its leading position in
international market by it advanced technology. Early in this year, GN has
improved its decanter centrifuge to make it more suitable to treat drilling
waste which contains relatively larger solids content. So GN made a series
specific design to reduce abrasion on the screw conveyor and avoid solids accumulating
inner the bowl cover. The new designed decanter centrifuge has been proven to
have stable operation and more satisfying performance, thus becoming popular in
the international market, especially in the Middle East and Africa, Latin
America. Recently GN delivered 6 sets of decanter centrifuge and 40 sets
agitators to South America. The new designed centrifuge also can be used as the
final stage solids control equipment in a complete set of solids control system for
oil and gas drilling. The mud agitator is used to rotate the mud to
keep it homogenous.

Now GN is manufacturing one set of solids
removal unit for a South America customer. It will be used the clean the
diamond drilling fluids for recycling usage. Besides solids control systems for
oil and gas drilling, GN also designs and supplies desander unit for bore piling and TBM; mud systems for HDD
drilling, CBM drilling, water well drilling, geothermal drilling. The main
treating equipment is shale shaker and desander, desilter, or mud cleaner with
the combination of desander cyclones and desilter cyclones. The shaker is used
to separate coarse solids, and then the desander to separate solids over 40 micrions,
and the desilter to remove solids over 25 microns.

4 sets GNLW452 Centrifuge for fast barite recovery

GN Solids Control decanter centrifuge is professional for
oil & gas drilling, horizontal directional drilling, coal bed methane
drilling, diamond drilling etc. The centrifuge is liquid / solids 2-phase
separation equipment, the separation point is 2 to 5 microns.

Recently, we have customer from CPP, China petroleum
pipeline bureau company, the largest HDD contractor from China. They just buy 2
sets of
500gpm mud system, each system equipped with 1 sets shaker with 2 ea desander
cones, 1 set shaker with 12ea desilter cones, 2 sets middle speed centrifuge
GNLW452. The middle speed centrifuge standard model is fixed speed centrifuge
with 1800RPM. The customer like customized centrifuge with variable speed
control panel. We company customized the fixed speed centrifuge to variable
speed centrifuge by adding one variable speed control panel with ABB transducer
inside to make the speed changeable. 1 set of GNLW452 centrifuge with treating
capacity 40m3/h, two sets means treating capacity 80 m3/h at same time. In this
case, the barite material in drilling mud can be take out by centrifuge very
fast. Thus, the total working efficiency will be promoted in a high level.

Except of GNLW452 middle speed centrifuge, GN
Solids Control also have other model centrifuge for other application.

1) GNLW363CG or GNLW363CG-VFD is high speed centrifuge,
fixed speed / variable speed two options for customer. This centrifuge is
professional for drilling mud weight reduce for solids control. Or it can be
used for drilling
waste management to remove the very fine solids from drilling waste, thus to
reduce the oil on cuttings (OOC).

2) GNLW553 big bowl big capacity centrifuge. If in some
certain case, the customer don’t want to use desander unit or desilter unit,
the customer may only use shale shaker & centrifuge for fast drilling. This
kinds of combination can also reduce the power consumption in a large degree. Because
when you use desander units or desilter units, big pump with electric motor is
generally needed.

GN other model centrifuge, like GNLW223 baby centrifuge,
GNLW453 big bowl centrifuge is also available.

Maintenance highlights of decanter centrifuge

While
operating well drilling, the drilling
fluid centrifuge machinery is one of the central
equipment that is often used, its purpose is mainly used for separating fine
solid debris whose diameter size are 2-7 μm from the drilling fluid. By using the drilling fluid centrifuge to
remove solid debris, it can effectively well lubricate and protected the drill bit;
it also has a very important role of improving drilling bit speed. With the oil
drilling industry ways and the technologies are getting mature; the drilling
fluid centrifuge manufacturing technology has been greatly improved as well.
However, there are some inherent mechanical issues if not solved it will give
the operators many function issues.

We as
manufacturer often have seen operators encounter issues below:

1. Bowl fault.
2. Consumable parts (inlet pipe, shockproof strip) problem.
3. Excessive vibration wile machine is currently working.
4. Outlet blocking by solids wish to remove from fluid.
5. Explosion-proof plug damage.
6. Centrifuge scroll damage.
7. Bearings failure while process of operation.
8. Drilling fluid centrifuge hoses damage.

We as
manufacturer suggest below if such issues operators encounter:

Operators
must understand that regular maintenance on the centrifuge such as regular
cleaning the inlet and outlet by filling water or diesel depends what kind of
fluid it needs process. It is also
crucial that add grease to the bearing parts to ensure proper lubrication.

Operators
needs regularly inspect often- damaged parts on the drilling fluid centrifuge,
such like hoses. In order to ensure the process in the use of these parts in
normal way this influences the production. Finally, electronic parts of the
centrifuge are working the best by running certain period of time frame (like
none-stop for hours). It needs, reduce the rapid turn on and off of the
centrifuge. If properly operate the centrifuge like mention above, then
operators will find out centrifuge failure rate will be greatly reduced during process
the drilling fluid.

Why Choose GN’s 4 Panel Shale Shaker for Solids Control

Shale shaker is a type of very common
drilling mud solids control in all kinds of drilling projects. As a leading
manufacturer of solids control equipment, GN could provide the shale
shaker and other mud recycling equipment for oil gas
drilling, horizontal directional drilling, water well drilling, tunneling and
piling projects.

The capacities of GN’s shale shaker are
200GPM, 500GPM and 600GPM under the mud condition of density 1.2g per cubic
centimeter, viscosity 45s measured by Marsh funnel viscosimeter and screen of
API 40.

GN Solids Control has a 4-panel screens
shale shaker which is the largest model in GN’s shale shaker product line. This
model could be used at the oil rig site for primary solids control. At the
consideration of easy operation and maintenance as well as the widely accepted
treating capacity, GN made the model of GNZS594E-HB shale shaker to fully
meet the market request.

So, what are the advantages of this model?
Or we say what the features are?

1. Simple structure design of the shaker
deck, the operator could observe the work performance easily. The added extra
horizontal square steel strips at both sides of the deck make the deck much stronger.

2. The 2 vibrators located vertically with
the beam makes there is a longer connecting face which could distribute the G
force uniformly to the whole shaker deck.

3. Hidden design of the lead screw beneath
the shaker deck makes it available to adjust the shaker deck angle while the
shaker is running. The operator only need a ratchet wrench to adjust the deck
angle from one side of the lead screw, the other side would be adjusted at the
same time.

4. To ensure the better sealing
performance, the screen frame was installed a type embedded rubber sealing.
This rubber sealing will not be taken off with the exception of manually
disassembling.

5. Wedge blocks are used to fasten the
screen panels is also a popular method. This makes the exchanging of the screen
easier.

6. Sometimes the shale shaker could be used
as a under shaker of the mud cleaner unit. All GN’s shale shaker will have the
pre cut installation holes to install the cyclone frame. Which means GN’s
cyclone frame for mud cleaner is removable. All cyclone frame, no matter what
capacity, the installation location would be the same.

7. By changing hopper feeder, GN’s 4-panel
shale shaker could be used as a drying shaker for waste cutting management. The
G force is up to 8.
