GN Solids Control has been focusing on solids control and drilling waste management fields for a long time. Each year, GN Solids Control produces about 150 decanter centrifuges and 400 shale shakers along with the other solids control tools. A majority of these equipment are delivered abroad because of the big international market.

Lately, GN has manufactured two decanter centrifuges for clients in Nigeria. Both of these decanter centrifuges are comprised one whole system for drilling liquids separation.

Naturally as is well-known, when two decanter centrifuges are utilizing together, the first is generally dealing with bigger capacity drilling mud, and the second can be used for separating finer solids. Even though the decanter centrifuge is principally accustomed to separate solids with diameter bigger than five microns, two decanter centrifuges have different separation function when cooperating.

Mentioning this system, GN suggested making use of two sets of GNLW 363 decanter centrifuge. The bowl diameter of the decanter centrifuge is 14 inch and the size of this decanter centrifuge is 50 inch. The treating capacity can achieve to 200 GPM. However for rotating speed of the decanter centrifuges, they won’t be the same. In order to save cash for clients, the first decanter centrifuge could be fixed speed at 3200 r/m. And the second could be rotating from 0 to 3200 r/m.

Once the drilling liquids with mud changes, we are able to adjust the rotating speed from the second centrifuges to fulfill the treating requirements. However, it might be easier to choose two sets adjustable speed centrifuges. When controlled by PLC, all operation work will be much simpler for workers.

Here both of these decanter centrifuges are generally fed by screw pump. GN use famous label screw pumps that are extremely effective feeding pumps, if this pumps is working, it can avoid agitating the drilling mud.

As many client need Clean Water at present, then chemicals finally up to the show. Having a reliable partner, now GN has also become providing the flocculant unit and coagulant unit, with the decanter centrifuge, to provide client a satisfied solution.

The Auto-Flocculant 6000 activity unit could be located in a really 20ft normal instrumentation and serve as a typical compact system for dealing with and using compound solutions.it also could be put in 40ft container installing a GNLW series centrifuge. Due to the integrated system, the preparation and dosing method might happen robotically. Connect ex gratia feature provides the risk of relevant a solids dependent dosing mechanism. Supported the data acquired from measure each volume rate and suspension density, the compound response is injected in to the method in connect quantity proportionate towards the individual solid matter. This type of system can absolutely exclude undesirable over- and/or underdosing.

The Auto-Flocculant 6000 activity unit is provided a liquid compound unit to make certain the automated and continuous preparation of the homogeneously mixed focused compound answer with precise concentration parameters in a two-chamber way (product quantity: 3000 l/h) a powder/liquid compound unit to make certain the automated and continuous preparation of the homogeneously mixed focused compound answer with precise concentration parameters in a really three-chamber method (product quantity: 6000 l/h) a programmable logic controller with bit screen panel for automatic operation flow meters and pressure sensors 2 dosing pumps for moving the premixed flocculant towards the injection purpose.

Two chambers or three chambers, inside container, or outdoors sitting on a skid, could be personalized as needed.

Even the programmer of PLC manipulating the system, have two options, the first is by timer, these parts by water flow and drainage. After involve in increasingly more projects, we are more professional on all of this. Keep tune.

Situated near to Beijing China Tower and Beijing International Airport, Hebei GN Solids Control enjoys a convenient location to attract foreign customers to visit GN factory and to established relationship. As the first API certified manufacturer of solid control equipment and system in China, GN solids control has a lot to say on the solids control system and equipment in oil and gas drilling field. Since established, GN has stick to the policy of striving higher quality and better service. With several year’s hard work, GN has also been certified by the CE by DNV. All these certificates indicates that GN Solids Control is a company worthy of trust and reliance.

GN manufactures and supplies solids control system for oil and gas drilling in various depth. In the whole set of solids control system for oil and gas drilling, generally there will be four stage treating equipment including shale shaker(1^st stage), desander(2^nd stage), desilter(3^rd stage), decanter centrifuge(4^th stage). Alternatively, the desander and desilter can be replaced by the mud cleaner with the combination of desander cyclones and desilter cyclone. And if the drilling is too deep, two sets of decanter centrifuge will be used. The one is medium speed, and the other is high speed decanter centrifuge. Beside solids control system, GN also supplies mud system for various kinds of drilling, and drilling waste management system for drilling cuttings.

Besides high quality product, GN also supplies considerate service:

Spare Parts: GN always have spare parts available in stock to ensure fast delivery.

Like an increasingly more important drilling area, TBM plays a huge role in urban buildings in many nations. Therefore the drilling mud system for TBM becomes increasingly popular. As top manufacturer for solids control systems and waste management systems in China, GN Solids Control have ever began business in HDD and TBM area, and today GN offer more appropriate and modern solutions to meet those needs.

For Tunnel Boring Machines, which in a nutshell is TBM, the conventional for drilling mud is high. Within this system GN designed and manufactured for that TBM contactor, there’s a GN Double Deck Shale Shaker, a GNZJ594-3S16N Mud Cleaner, a 20ft container GN Dewatering Unit, a GNLW363BG-VFD Decanter Centrifuge as well as their necessary pumps, as well as an extra tank for arranging the drilling mud for entering the drilling system.

Each equipment’s functions:

1. GN Double Deck shale shaker. This shale shaker has 2 layers of screens, and also the lower layer’s screen is a lot finer the low layer. Then your drilling mud might be regarded as two times treated through the shale shaker, with only a little space occupied.

2. GNZJ-3S16N mud cleaner, a mix of desander cones, desilter cones and shale shaker, desander cones and desilter cones could separate out solids contaminants bigger than 20 microns, and also the API 200 drying screen can help dispose large contaminants.

3. GN 20ft Container Dewatering unit. With the addition of some chemicals in to the drilling mud, the flocculation helps you to collect the more compact contaminants into bigger contaminants, after treated by GNLW363BG-VFD high-speed centrifuge.

4. Well treated drilling mud with ideal proportion then makes its way into the arranging tank for later in to the TBM drilling system.

5. Besides all above pointed out, this customer also purchased another group of GN double deck shale shaker and GNZJ594E-3S16N as backup.

Lately, GN has produced several teams of such systems for clients in various areas and regions. For those who have interest or similar need, please get in touch freely.

Lately, GN’s drying shale shaker system has finished its commission. As GN stay with quality and repair, best of luck is just looked over before delivery from GN factory, and complex mud system GN provides commissioning service by dispatching engineers towards the working site.

As proven within the below introduction, the mud cleaner is installed between 2 models of shale shaker. It’s not general layout, once we have spoken that for any solids control systemor perhaps a mud system, mud cleaner (normally the alternative of a desnader and desilter) within the next stage to process drilling mud after shale shaker. Even though it is specifically created by GN engineer using the thought on narrow space within the working site, and fully thinking around the pipe connection. GN engineer strongly and thoroughly modified the overall design by finding the mud cleaner between 2 models of shale shakers. The drilling mud pumped out of the well is going to be given individually towards the 2 shale shakes for treatment, and they pumped in to the mud cleaner for more process.

Regarding towards the shale shaker, to safeguard it from damage, its deck is locked throughout transportation. Prior to the trial running, the operator need fixed the shale shaker on the top from the mud tank and unlock when. GN shale shaker‘s vibration motor originates from famous label Italia OLI or Martin with explosion -proof consideration for performance and safety. GN is first API licensed solids Control Company in China. Near the above two features, Simple structure is among the options that come with the GN’s shale shaker, the consumer can certainly master how you can operate it and perform the commissioning themselves. Concerning the control panel, GN provides electric diagram, the operator can begin and switch from the shale shaker without an excessive amount of electrical understanding.

As GN produces increasingly more solids control tools and drilling waste management systems to fulfill clients altering demands on drilling fields or Non-search fields, clients have greater and greater demands on GN Solids Control that is supplying them the required costume parts for example shale shaker screens.

Now GN will quickly establish his new factory to meet the requirements of huge quantity shaker screens. Around the finish of the year, GN new branch factory can help GN to create a lot more shale shaker screens, which new branch clients are quite close to GN Solids Control Company. It’s this kind of very good news for GN as well as for GN clients.

Usually, GN can establish from 5000 pieces shale shaker screens to eight 1000 pieces shale shaker screens each month, however, thinking about the big need this manufacturing capacity isn’t enough. Anyway, based on new factory, GN will solve these complaints perfectly well, and GN will introduce many advanced CNC machines to enhance the development, in addition to hire more knowledgeable employees to focusing on this special area.

For GN Solids Control, a myriad of shale shaker screens could be created, like the hook strip flat screens, the pyramid screens, hook strip soft screens and steel frame screens etc.

If you’re able to title the screen, then GN will design and manufacture them. The great characteristics which are adopted strictly by GN engineers, therefore the world most well-known brands could be exchangeable and carried out well on many different shale shakers. By utilizing GN shale shaker screens, our clients cannot only keep your same performance because the renowned brands screens, but additionally can same much cash around the cost. For this reason our clients always call GN shale shaker screens economical.

With lots of effective encounters, GN has over 60 countries’ clients which are using his shaker screens, so we believe case the great start of GN shaker screens, later on increasingly more clients may have the chance to become familiar with GN.

Normally for 1000HP drilling rig, or for the drilling rigs drilling holes upto 3000~4000m; we recommend 200cubic meters mud systems.

The system contains two linear motion shale shaker, GNZS703 / GNZS594, then a GNZCQ270 vaccum degasser, one GNZJ703-2S12N / GNZJ594-2S12N mud cleaner.

Then for optional, we can have decanter centrifuge, company with feeding screw pump. Depends on the different drilling site.

The system get 4 mud tanks, one for cleaning, one for mixing, and two mud tanks for storage. Normally we get tandom jet mud mixer on the mixing tank, while keep all clean tanks or compartments mixable. The mixed mud can reach all the clean mud, and can be transfered as required.

The centrifuges for option:

GNLW452 18inch big bowl centrifuge with 1800rpm middle speed for bariter recovery

GNLW363 14inch centrifuge with different fixed speed, or VFD panel for high /low gravity solids recovery.

While except have optional choice for centrifuge, sometimes, if it is for geothermal project, we do not need vaccum degasser. That is also no problem, we have just sent one mud system to Turkey, which is for 1000HP geothermal drilling rig. No centrifuge, no vaccum degasser.

Another customized option is mud tanks design.

Then tanks can be customized layout as the rig site requried, also considering saving the inland freight cost, sea freight cost, and so on. Also if you have partners who is fabricating mud tanks, you can make by yourself, and GN will supply fully technique support. Drawings, and detaisl for your information.
