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.

How Does the Cyclone Work as a Solids Control Equipment

The persons who are in the drilling
industry may might not unfamiliar to the cyclone unit. The cyclone units always
get into to our view as a de-sander, de-silter or even mud cleaner equipment. These items belons to the solids
control equipment which is used to recycling the drilling mud to reduce the
drilling cost, and for some environmental friendly purpose.

As per the diameter of the cyclone straight
body part, the cyclone units are divided into 2 types. The units with a
diameter larger no less than 6 inch would be call as de-sander cyclone, while
others smaller than 6 inch would be defined as de-silter unit. The cyclone unit
is working by using the centrifuge force to separate the solid phase and liquid
phase.

Generally, the cyclone unit has 3 ports,
one is used for fluids fed in, and the rest 2 are separately used for liquid
overflow and solids discharging. The cyclone body was divided into straight
part and cone part. The fluids was pumped into the cyclone under the pressure
of 0.25-0.4 Mpa along with a tangent direction of the cyclone inner wall.
Rotating inside a cyclone at a very high speed, the solids and liquids would be
layered toward the cyclone wall with solids close to the wall and liquid in the
center.

So, how can the cyclone separate the solids
and liquids? At the bottom of the cyclone, there is a discharged port which is
a small hole. The high speed rotating layered solids would get down to the
discharge part and get out as a umbrella shape, high speed rotating makes the
centre of the discharge port a vacuum where the air can get into the cyclone.
Under the pressure of air, the liquid would overflow out from the outlet at the
top of the cyclone. Normally, the bottom discharged solids would have about
20-30 degree angle, much less or more would be treated as abnormal working
condition.

GN Solids Control always adopts the 10 inch
cyclone to be the de-sander cyclone which could
separate the solids with size large 45-70 microns. The 4 inch cyclone is used
as the de-silter to remove the solids larger than 15 microns. This cut point is
a very vague data. By compositing different size cyclone and under shaker unit,
GN
solids control could provide the de-sanding and de-silting unit for various kinds of drilling projects.

GN Centrifugal Pump to Deliver Drilling Fluids

GN solids control distinguishes
itself from other China’s manufacturers by its cost-effective product with
competitive price to USA/EUEOPE brand but with fine and stable performance.
Beside supplying solids control equipments such as shale shaker, desander, desilter, mud cleaner, and decanter centrifuge, GN solids
control also supplies centrifugal pumps to deliver drilling fluid.

With stable performance and long service
life, GN SB series centrifugal pump is designed to deliver abrasive, viscous,
corrosive media, especially drilling fluids and industrial slurry. The pump can
handle large volume flow up to 320m3/h, withstand high temperature, and
remarkably save energy, but is easy to maintain. Currently, GN centrifugal
pumps are operating widely both on onland and offshore drilling rigs around the
world. Taking drilling fluids’ condition into consideration, we are committed
to offer the best solution to our customers.

The housing of GN centrifugal pump is thicker,
heavier and solider because of the special strength when compared with
conventional pumps, thus enjoying a more durable and longer service life.

The annular flow channel inside the housing
will eliminate turbulence and cavitation, also reduce radial load on the
bearing. The housing gasket is recessed to prevent fluids from leaving the
impeller. In oil and gas field, centrifugal pumps are mainly used as feeding
pumps to desander, desilter or mud cleaner, mud mixing pump, and supercharging
pump to mud pump. Regarding to the first application, the liquids discharged
from shale shaker will be delivered to the desander, desilter or mud cleaner by
the centrifugal pump, always horizontally installed on the skid of mud tanks.
To the second, the chemical will be added when the centrifugal pump discharges
the fluids out, usually fixed below the mud mixing hopper, also on the skid of
tank. For the third, the centrifugal pump will be used as supercharging pump
for mud pumps.

The 5 steps purify drilling mud

Drilling mud purifications
is the basic to insure the function of drilling bit works properly and safely
for both oil rig equipments and many operators working around the clock in the
drilling field.  Needless to say, it is a
very costly operation if one or many steps of drilling operation go wrong, It
will leads operation cost of drilling rig go double in very short amount of
time that leads to increases of operation cost and late leads to increase the
production cost of oil.    

The first level of purification

The mud feed in the shale shaker. The allocation drilling fluid
enter into the bottom of the drilling well under the foundation of the drilling pump
and carry drilling debris return the ground,
through the feeding enter into the shale shaker, the larger solid debris in drilling fluid are filtered through shale
shaker screen.

The second level of purification

When drilling fluid have debris and also contain gas, The use of vacuum degasser remove the gas which in the
drilling fluid and can recover the density of drilling fluid, calm the drilling fluid viscosity.

The third level
of purification

The drilling fluid is disposed by two level purification enter into the desander.  Through the desander feed into the liquid pump, the harmful sold phase which the diameter
is above 40-60um is separated in desander.

The fourth level of purification

The drilling fluid is disposed by the three level purification enter into the desilter
through the desilter feed into the liquid pump, the harmful sold phase which the diameter is above
15-40um is separated in desilter

.

The fifth level of purification

The drilling is disposed by the four level purification enter into the decanter centrifuge through the centrifugal feed liquid pump, the
small harmful sold phase particles are separated in decanter centrifuge
