Sources and Sizes of Drill Mud Solids

There are 2 main sources of drill solids
particles are the chemical additives and formal drilling cuttings, the drilling
cuttings are containments that degrade the performance of drilling mud. The
drilling particles will be ground into smaller and smaller and become more and
more difficult to remove from drilling mud if the drilling cuttings that not removed as per guide. Most of the
formal drill solids will be able to be removed by mechanical ways by drill
solids separate equipment and small drill particle will be very difficult to
remove and will have a great effect on drilling mud properties than the very
larger drill solids particles . The solids particle size in drilling mud
incorporated into drill mud will be range from 1 to 250 microns.

 The clay, colloidal and bentonizte will be
size between 1 to 5 microns, silt, barites and fine cement dust will be 6 to 44
microns, fine sand will be between 44 to 74 microns, API sand will be 105 to
149 microns, coarse sand can be 500 – 1000 microns, coarse that larger than
2000 microns, there will be colloidal that bellow 2 microns.

Drilling solids particles are the main contaminant
in the drilling mud, so the control of the importance of the good solids
control including increased the penetration rate and reduce mud cost, reduce
water requirement, reduce mixing problem, reduce differential striking, etc.
The drilling solids removal is important to keep drilling mud recycling and re-use.
The
main equipment for drill solids removal are shale shaker , desander, desilter, decanter centrifuge and there will be other
machine assistant to meet separation application including mud tank, centrifugal pump, valve and pipeline.

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.

GN HDD System for Australia

In recent days,
GN will deliver to Australia a 500 GPM mud recycling system for HDD.
It is one of GN’s best seller products as the mud recycling system. And 500 GPM
is the most popular configuration among all the available configurations.

As is known to
all, Australian market for the equipments and machines are different from other
markets, because Australia has a even higher standard and more strict rules for
the machine or devices or the environment protection. Some laws and regulations
are even more strict than their peers like USA and European countries.

Although Australia
has such standards, GN Solids Control and GN
Solids Control’s equipments was accepted by Australia. In fact, GN is
the first and only solids control manufacturer who provided to Australia.

Why GN Solids Control?
As a private owned company, GN has no special background or mother company to
be covered with. That’s why the quality is the most important thing. To win a
future and reputation is always what GN does for the past years, and for the coming
years also. Year in and year out, GN has developed from a small company to a
world well known brand.

In domestic
China, there are lots of HDD contractors who buy from GN, and they are giving
repeated orders because they found GN a reliable company with good quality
products. In outside China countries, GN provided to South America, to Asian
countries and to Middle East countries like Saudi Arabia.

When talking
about clients’ countries, we can not let go Saudi Arabia. Before meeting GN
Solids Control, the Saudi Arabia HDD companies only purchased from US brands,
for shakers, desander, desilters and complete
system. But they turned to GN for more cost-effective solutions, maybe at first
they just had a try, because they didn’t believe in some Chinese
manufacturers,. But later GN proved to them that there are high quality Chinese
equipments.

And also, many
HDD rig companies are sourcing from GN to make rig package with GN mud
recycling systems.

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,
