Shale Shaker for Trenchless Technology

Shale
shaker is designed to separate drilling cuttings above 100 microns by shale shaker screen separation ; there
are 2 sets of vibrator motor installed on shale shaker to supply vibrating
power at 7.0 G force. Different design of drilling
mud shale shaker may have different size and capacity, there
will be 2 or 3 or 4 panels for a single deck shale shaker for install shaker
screen with wedge type or hook type screen installation. All GN oil field shale
shakers are – 1 to 5 degree shaker deck adjusts range and trenchless shale
shaker is +2 degree shaker deck angle.

GNZS752E
mini shale shaker for trenchless
mud system that mud flow no higher than 200 GPM, it is
installed 2 sets of 0.75 kw vibrating motor at 6.5 G force with 2 pc shaker screen
on shaker deck with 1.35 square meters screen area, The screen can be install
20 to 100 mesh screen for drilling cuttings separation between 150 micron to
400 micron separation size. GNZS703E shale shaker is another trenchless
industry shale shaker for mud system that 300 GPM and above , this is a three
deck shale shaker with 3 pc shale shaker screen installed for 500 GPM mud flow
max by 40 mesh shaker screen . It is installed 2 sets of 1.72 kW vibrator motor
to supply 7.0 G force for shaker vibrating.

The
desander and or desilter
cyclones can be installed on any shale shaker to make
it as a mud cleaning for finer size separation , the desander cone can separate
50 microns and above and desilter cone separate 20 microns and above. The
minimum capacity of desander cone is 500 GPM, so we won’t be able to install
desander cone if mud flow required lower than 500 GPM but we can install
desilter cone in that case.

Hook stripe flat screen and corrugate design screen comparison

It is mostly used design by
current that can fit several of shale shakers that
coordinate with the design concept. It is made with multiple layers of stainless
steel wire clothes together to a steel support plank. The characteristic of this type of shale
shaker screen are list below:

l
It contains different meshes on wire
cloth in the screen. The sizes of the
holes that support the plank contain different mesh as well. The support plank size also is different as
well. Combine it all will get area that
is effective on condition to bearing enough liquid flow force.

l
The thicker wires cloth contain less
mesh at the lower bottom of the screen together with support plank so it can
added strength of the whole screen to extend usage life.

l
The wire cloth is divided into many
small surface grid of steel support plank which can hold the excessive
expansion to make it last as long as possible.

Corrugate-design
shaker screen

With demand of larger and larger treating capacity
of the drilling fluid but without building larger shale shaker, the corrugate
design screen was appear in 1990s to increase the treating surface and to fit
current use shale shaker.

Corrugate design screen has large effective area, and drilling fluid
is handled in high-efficiency by using it.

This kind of sieving screen has design characteristics as follows:

l
Every wire cloth in the
sieving screen has different meshes, and accurate collocation can make the
screen have better liquid treated effect.

l
Stainless steel wire cloth is made
it like corrugate, and closely holds metal support plank together. The
effective area can added up to 125% of the flat screen with the same specification
and the size, so as to improve the quality and treating amount of drilling
fluid and increase the production.

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.

Dual Centrifuge mud system for CPP

GN Solids Control have many
production project for CPP from year of 2010. CPP is the largest HDD contractor
from China and engaged in China and overseas market. GN Solids Control compact
mud system and centrifuge is also working in many different jobsite with CPP
teams.

Beginning of this year, we got 4 sets 500gpm mud recycling system for
CPP. Different from former system configurations, this time CPP require 2 sets
variable speed middle speed centrifuge for each system. In this case, they can
recover the barite from used drilling fluids fast. The centrifuge is GNLW452
big bowl middle speed centrifuge with variable speed control panel to adjust
the speed flexible.

Except for 2 sets middle speed centrifuge,
other solids control equipment including:

1) 1 set Mud desanding cleaner GNZJ705-2S, with double deck shale
shaker GNZS705. It is for the first and second stage separation.

2) 1 set Mud desilter cleaner GNZJ705-12N,
with double deck shale shaker GNZS705.
It is for the first and third stage separation.

3) 2 sets mud agitator installed on
centrifuge tank compartment, to avoid drilling mud settle down.

After double checking the whole system, you
can find the HDD mud system with 2 sets shale shaker, 1 set desander assembly ,
1 set desilter assembly, 2 sets centrifuge. The treating capacity is much
bigger and the drilling mud can go to desanding cleaner and desilter cleaner at
same time. The drilling fluids go into this two units via distribution box and
controlled by flange and valves. Generally, the actual treating capacity can
reach to about 800gpm to 1000gpm.

GN Solids Control is famous solids control
equipment mfg from China with rich experience in compact mud system
fabrication. The different mud system capacity including: 500gpm mud system,
800gpm mud system and 1000gpm mud system.

Except for small mud system for HDD, CBM,
TBM etc, GN also produce lots of oil drilling mud system every year for oil
drilling companies. If you need more support, pls contact us freely.

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.
