API SHAKER SCREEN

In some degree, the mud agitators and mud
guns are more commonly used than the main solids control equipment like the shale
shakers and centrifuges, because besides the solids
control system, there is also mud plant or mixing plant. In such systems,
they use only mixing hoppers and pumps for treating the drilling fluid and the
main function of the whole system is to storage the drilling mud for the future
use.

In order to keep the drilling fluid from
being deposit to the bottom, they need mud agitators and mud guns to prevent it
from settling down. Normally, every mud agitator is matched with one mud gun,
and each 3 meters ,there is a mud agitator.

GN has variable mud guns available, some
are of smaller horse power while some are of larger horse power. Which one to
choose depends on 2 factors, the first one is the depth of the tank, the deeper
the tank is, the larger horse power of the mud agitator is needed. The second
factor is the mud condition, always, the more sticky of the mud, the larger
horse power mud agitator is needed, it means the viscosity of the mud

GNJBQ series mud agitators,
especially for the larger horse power ones, has 2 options, the single impeller
one and the double impeller one, the double impeller one is more suitable for
the deep tank situations. On the bottom of tank, GN always suggest the end user
to use bottom shaft stabilizer for limit the long shaft to be working within a
suitable range, not to deviate from the center.

The mud guns are used to help the mud
agitators to play the same role, especially for the corners of the mud tank. GNNJQ series
mud guns has 4 options, the 2 inch mud gun and the 3 inch mud gun, each
diameter has 2 options, the fixed ones and the rotary ones. Comparing with
other China brands, GN mud guns use polyurethane as nozzle material, with
longer service life. It is also the most popular choice internationally.

GN Solids keep one set of HDD mud recycling system stock in Brisbane for sale with big discount as we are trying to sell this 200GPM HDD mud recycling system to stock a new design of mud system later . The HDD mud system is same procedure with oil and gas solids control system but it will require special design that different with oil and gas drilling solids control system depending on it’s different conditons , the detail special as follows :

1) HDD mud recycling system need very compact design cause it’s moving cost very high compare it’s profit , the more compact , the easier and lower cost for moving or transport . The best design is try to avoid crane for moving cause crane cost too much . The walkway and hand rail normally can be folded down or up without disassemble , and mud cleaning equipment lay on tank top within road transport height limit .
2) Most of HDD mud recycling system is one tank design , and many tanks are trailer mounted or jack up legs for fast moving . GN Solids built many sets of jack up mud system to Australia for fast transport which is very convinent and not related to too high standard , there are supplier for trailer mounted tank also which have a same purpose for fast moving mud tanks .
3) Total dimention will need meet local road transport regulations , when design the whole mud recycling system , the engineer need consider all dimentions and finish dimention and keep sure all will be fine after finshied

Other than some of mud recycling equipment or system , GN Solids Control keep standard spare parts in Brsibane , Australia for fast service to clients there . Please contact GN Solids for more information if you interest for the stock .

Mud recycling system is well used for oil and gas drilling , coal gas methan , horizontal directional drilling ( HDD ) , diamond drilling and other drilling mud industry . When the mud recycling system working for HDD drilling , there will be some key point that different for other drilling industry .

Main Key Points Of HDD Mud Recycling System

Point 1 , it will require 2 sets of mud recycling system cause there are 2 rigs drilling a hole together at a close position . But for other vertical drilling , there will be one set of drilling rig and one set of mud recycling system .

Point 2 , it will need economy cause profit is low in HDD industry , just as every body say , if there is a centrifuge , it will be good for recycling but seldom people choose a centrifuge cause save money and power .

Point 3 , it doesn’t require very high for drilling mud , so the requirement of recycle drilling mud is not high also . The horizontal directional drilling not drill deep , and just several meters under ground , so the drilling mud quality not required very high .

Point 4 , it need compact design and can be move and transport fast . So the design of themud tank , pipeline and other details need be very compact , many client need container size tank or trailer mounted mud tank , handrail and walk way can be folded down or up , the equipment can be easy installation or diassemble , or all equipment lay on top of tank while moving .

GN Solids is one of a professional supplier in the world for HDD mud recycling system and already did many project for all over the world . Please contact GN Solids for more information .

GN Solids Control VertiG is tested
equipment to show good performance in many jobsite. We compete with US brand
and Europe brand, and we win many tenders from them.

Eg.

1)      
We have VertiG working at Baker
Hughes jobsite, working performance is fine. Clients give high praise feedback.

2)      
GN Solids Control VertiG is also
working for Shell OBM drilling cuttings management. We beat CSI vertical dryer
and win this purchase order.

3)      
GN VertiG with decanter
centrifuges is also working for Iran largest mud service company and Egypt
largest mud chemicals service company. GN equipment show high working
performance at both middle east and North Africa

In West Africa, we also have some big
clients. One drilling company (we call it WADC in next content). WADC is a
drilling company with 7 land rigs and many oil blocks. They start it project at
Nigeria about 8 years before and have very good reputation in drilling field
Nigeria. GN Solids Control holds hands with WADC about 3 years before and from
that time, WADC buy lots of equipment from us, especially for decanter
centrifuges and VertiG ( vertical
cuttings dryer). Formerly, the company rent equipment with manpower service
from Schlumberger; the cost is very higher from long term use. Now they only
use decanter centrifuges and vertical cuttings dryer and use their own
manpower, cost is very good and manpower is relatively very flexible.

What is the advantage of US brand solids
control equipment ?  Generally, the user
is more familiar with US brand solids control equipment. US brand start earlier
and train lots of service people in a world wide range. So, the drilling
company can get US brand equipment with good trained service people to get
better service. However, if they buy from China, even the equipment operation
is almost same, they have a Conflict psychology to refuse China solids control
equipment, even it is high quality and friendly for use.

As China leading brand for solids control
equipment & Drilling
waste management equipment, we not only offer high quality equipment, but
also offer training schedules.

GN Solids Control built one set of mud plant for North America including 4 sets of mud tank , 1 set of shale shaker , 2 sets of high speed decanter centrifuge , 2 sets of submersible slurry pump for feeding decanter centrifuge and tank attachement . The mud plant normally close to drilling area where may allow many drill rig working but treat drilling mud together or after finish drilling . It will be contain high volume of drilling mud and need equipment to separate drilling cuttings and fine solids out of drilling mud .

Main Equipment Will Be Used For Drilling Mud Plant

Shale shaker will be required to separate drilling cuttings , depending on mud plant size and capacity , client will choose different model and quatity of shale shaker . This client choose one set 2 screen shale shaker for about 200 GPM mud flow capacity .

Decanter centrifuge will be required to separate fine solids after treatment by shale shaker , the shale shaker will treat about 150 microns by 100 mesh screen , then one set high speed centrifuge will separate solids 5 microns and above or 7 microns and above by middle speed decanter centrifuge . There are different models from GN Solids with different treating capacity and treating effictivity .

Mud tanks will be require to storage dirty and clean drilling mud before and after treatment , normally they will require many tanks to storage clean mud after treatment as they need some spares in case no space for dirty mud treatment . The mud tank size can be customized depending on jobsite condition and requirement or clients requirement . Many clients choose 40 feet container size mud tank consider of transport locally but some client like more capacity of mud tank to save space .

GN Solids Control sell a series of solids control equipment and drilling waste management equipment including vertical cuttings dryer , shale shaker , screw conveyor , screw pump , oilfield shale shaker , mud cleaner , desander and desilter , vacuum degasser , poor boy degasser , decanter centrifuge , mud tank , mud agitator , etc . GN Solids Americal normally keep stock for GN main product and shale shaker , mud cleaner and decanter centrifuge always keep stock there to service local client .

The shale shaker is the first phase cleaning for drilling mud , 3 decks and 4 decks shale shaker is the first phase cleaning at 100 to 400 micron and above by 40 mesh shaker screen or higher mesh size . The frame type shaker screen design for fast replace of shaker screen during drilling . The shale shaker can be installed desander and or desilter cyclone for finer treatment and quatity can be customized depending on client requirement . All GN shale shake is linear motion and G forth no higher than 7.5 G , the deck angle adjustment between – 1 to + 5 degree by wheel adjustment .

Decanter centrifuge is the forth phase cleaning equipment for separate solids 2 to 7 microns depending on model choose , the high speed decanter centrifuge separate solids 2 to 5 microns and middle speed centrifuge separate solids 5 – 7 microns . The GNLW363 centrifuge is the most popular model in GN Solids America and treat mud flow 30 cubic meters per hour at 2 to 5 micron separate by 3200 RPM rotating speed .  Please contact GN Solids America for more information or inquiry of GN stock shale shaker , mud cleaner and decanter centrifuge .

Drilling waste management system contains several equipment and tank to make a full solution including vertical cuttings dryer for dry drilling cuttings , decanter centrifuge to recycle drilling fluids out of vertical cuttings dryer , screw pump for feed decanter centrifuge and flush outlet of vertical cuttings dryer , air compressor to supply air for air knife on vertical cuttings dryer , screw conveyor to transfer drilling cuttings , mud tank and work plat form to make all process continuously .

Vertical cuttings dryer is one of the core equipment and will dry drilling cuttings with fluids content bellow 5 percent at 900 RPM rotating speed tank body . The screen can be use 0.25 to 0.5 mm size depending on requirement , one set of air knife will be needed to match vertical cuttings dryer which is powered by one set of air compressor . One set of screw pump will be needed to flush outlet fluids to keep sure fluids will be flow out when high viscosity and density . There will need minimum 2 sets of screw auger to feed drilling cuttings into vertical cuttings dryer , one set horizontal to collect drilling cuttings from shale shaker , desander and desilter , another one to feed drilling cuttings to vertical cuttings dryer .

One set high speed decanter centrifuge to recycle drilling fluids that recycled by vertical cuttings dryer at 2 to 5 microns separate at 3200 RPM bowl speed . one set of VFD control panels is optional , the VFD control panel will change speed of centrifuge bowl from 0 to 3200 RPM but quite big size . If you want small footprint , then you can choose one set of fixed speed decanter centrifuge .

Other than the vertical cuttings dryer and decanter centrifuge , there will be other equipment to cooperate like screw pump , tank , work form , etc .

Containerized drilling waste management system normally will be used in Russia for lower temperature and winterized conditions . GN Solids Control delivery the third sets of containerized drilling waste management to the same client last week and get a good feed back of drilling waste management equipment performance in Russia . The main equipment will including vertical cuttings dryer , decanter centrifuge , screw conveyor , screw pump , 40 feet container and work skid .

40 feet container supplied to keep vertical cuttings dryer and other drilling waste management equipment inside for winterization design . We made some changes on the container like doors or windle depending on working requirement . The whole container size on a big work platform to hold all above and make a base for the cover and temperature issues .

One set vertical cuttings dryer with 930mm size diameter tank and 900 RPM rotating speed to allow drilling cuttings treating flow reaches to 30 to 50 cubic meters per hour . the dry solids treated by vertical cuttings dryer will reduce fluids and fluids content will be bellow 5 percent totally . One set screw pump will be installed to flush vertical cuttings dryer incase fluids content a lot of fine solids and make it hard to flow . The air knife will make client need a air compressior and this design is for avoid screen block by water base drilling cuttings .

One set of decanter centrifuge will be installed to recycling drilling mud that recycled by vertical cuttings dryer . It is high speed centrifuge with 3200 RPM rotating speed for separation 2 to 5 microns solids out and 30 cubic meters per hour drilling mud flow max . The tungsten carbide tiles is bolted on screw impeller to help screw working longer life .

Linear motion shale shaker is the most popular design of shale shaker for oil and gas industry and steady working performance . GN Solids bring one set of linear motion shale shaker to Indonesia for show and delivery it back after the show . There are many supplier that related with drilling appear in the show with good feedback of show . GN Solids shale shaker attract eyes of the visitors cause seldom solids control supplier bring a equipment to show .

There are 3 options for GN shale shaker , GNZS703 , GNZS594 and GNZS752 for 4 decks , 3 decks and 2 decks . Client can choose to suitable model depending on there drilling conditions and mud flow requirement . The 2 decks shale shaker normally working for horizontal directional drilling , and small coal gas methan drilling rigs . 3 decks and 4 decks shale shaker can be use for oil and gas drilling , coal gas methan drilling and gethormal drilling , etc . The 4 decks shaker can be used for drilling waste management also cause the longer deck help dryer drilling cuttings better . Both GNZS703 and GNZS594 shaker deck can adjust deck angle from -1 to 5 degree depending on drilling mud conditions and GNZS752 shaker fixed +2 degree .

Other than shale shaker , if install different design of cyclone will change shale shaker to be desander , desilter or mud cleaner . The GNZS752 shaker normally for desander or desilter only cause screen area not big enough but GNZS703 and GNZS594 shaker can be make desander , desilter separated or a mud cleaner for a three in one cause larger screen area . After the desander and desilter , GN Solids can supply a decanter centrifuge for forth phase cleaning to 2 – 5 microns fine solids . Please contact GN office if any inquiry .
