Desander Desilter

Several months previous to, GN solids control obtained the order from one household customer for one unit sleek and stylish mud recycling system with regard to HDD, the required the dealing with capacity is 500GPM. GN’s model is GNMS-500GL. At the moment this unit already fantasticly run at 3 internet sites, today we got the picture of the unit working on site.
For all those GN’s equipment, as per the customer’s requirement, GN would mail the engineer to web site for guiding how to set up the equipment, tell the customer just what should be taken care about if operation, and also train the particular clients operator. Below may be the picture of this 500GPM model, this unit is self-contained design with all the stages to get drilling mud solids control and mud mixing & reconfiguration.

The mud tank ended up being divided into 4 compartments such as the shaker compartment, de-sander area, de-silter and mud mixing area. Due to in HDD task, no need to separate the cuttings up to very fine, thus, the particular recycled drilling mud can be reused after the treatment with the de-silter unit. This device is long enough to have adequate space in the mud container to store the active soil.
Various GN Compact mud Recycling System Application
GN is a leading manufacturer associated with solids control equipment within China, no doubt, the necessary oil gas drilling industry is a very important market for GN, the mud system to get oil drilling is tad bit structure complex and large presence. However , in the meanwhile, GN developed various compact framework mud system especially intended for No dig drilling undertaking, coal bed methane pursuit, piling project and small tunneling.

2) Decanter centrifuge: GN decanter centrifuge is used to eliminate the fine solids, minutes separation points about 2-5microns. After treated by GN centrifuge, the drilling mud might be reused after weighted or perhaps chemical adjusted.
3) Screw pump motor: screw pump feed to get centrifuge also attached in often the mud system tank skid. This positive displacement pump motor can work stable without agitating the drilling mud. The providing performance is much better than other style pumps.
4) Mud tank skid: All equipment is mounted on a single mud tank, compact and for movement. We furthermore design extra space intended for client’s generator as per their very own requirements.

We also have various other projects for Europe this season. In Jan, 2015 most of us export 3 sets 1000hp drilling mud system there. Could you get more info from Backlinks. Since GN focus on the quality products, GN Solids control equipment is working in over 62 countries and areas. Most of us win good reputation after years overseas marketing. We have GN Solids America and GN Solids Russia branch workplace to give fast response to The usa market and Russia market place.

As first API certified solids control manufacturer in China, GN Solids Control has provided to more than 60 countries and regions with its cost effective products, covering all related main equipment of solids control and drilling waste management line for oil and gas drilling.

The main principle of the solids control systems is physical separation, using the physical characters of different media, the solids control equipment separate as much solids from the liquid. Right now, in other industries besides the oil and gas drilling, such functional equipments are also chosen by the end users, to make their work more efficient and easier.

Physical Functions of solids control equipment:

Since the most important solids control equipments are respectively shale shaker and decanter centrifuge, we talk about only these 2. Now in many oil and gas drilling jobsite, the end users choose to use more shakers and centrifuges instead of former hydrocyclones.

1. shale shaker. Shale shaker is the most efficient equipment in solids control process, because it uses less energy while separates the most solids out of the liquid by using the different size of the solids and by means of different size mesh on the shaker and a couple of vibration motors. The disadvantage is that the shaker could not separate very fine particles, and its separation work is a bit draft. GN has 3 nos screen shale shaker and 4 nos screen shale shaker for option with model GNZS703E and GNZS594E.

2. decanter centrifuge is a high speed rotation machine, mostly horizontal. It has a high speed rotating bowl and inside bowl there is an impeller. During the rotating, the centrifugal forces on different material are not same, that causes the liquid phase continuously flows out of the bowl while the solids particles are slashed on the bowl inside wall and pushed out of the centrifuge solids discharge ports. The decanter centrifuge a gentle and precise, more costly than shale shaker, not only the cost of itself, but also the consumption of electric power. But it is ideal solution for separating out the fine and extra fine particles. GN centrifuge family covers all common sizes of decanter centrifuges from 9 inch bowl diameter to 22 inch bowl diameter, among those centrifuges, GNLW363 with 14 inch bowl is the most popular model.

Since its establishment in year 2007, GN Solids Control, has been growing and expanding fast. As a 100% private owned company, GN Solids Control has no much background. But ever since the owner started the company, he always believes that Quality is first, Price is second. Leading in this direction, GN win the good name in this industry.

 

GN facilities:

GN Solids Control started in a city named Tangshan, and its former name was Tangshan Guanneng. Later, 3 years ago, GN changed name to Hebei GN Solids Control and moved its main facility to another county in Langfang City, in order to get larger workshops and more advanced manufacturing facilities.

As the expanding of business in all over the world, GN Solids Control’s equipments and systems have been exported to more than 60 countries and regions, one facility is clearly not big enough, especially for most popular product decanter centrifuges. So GN Solids Control constructed a second facility, with 5 more workshops and a new office building, which are for centrifuges, VG dryers and other rotating equipments.

As a leading solids control manufacturer, shale shaker and mud cleaner are essential equipment for not only solids control systems, but also for the mud recycling systems for other drilling projects like HDD, TBM, water well drilling and etc. In order to better control the performance of GN Shale Shaker, GN started a shaker screen factory also. Now GN brand screens is enjoying good name among clients.

Now GN Solids Control’s new factory is nearly ready, and is scheduled to be open early next year.

It is located in the same industry zone as GN main facilities, only 7 kilometers away from the existing facility.

 

Both of the two facilities are located in Dachang Chaobai River Industry Zone, only 40 kilo meters from Beijing International Airport, China. May you have opportunity to come to China, welcome to inform us and visit our factories. Please kindly find links here www.gnsolidscontrol.com.

The mud tank design affected by the whole drill site and procedure , the surface pits or dirty mud storage is comprised by active circulation system to contain enough usable drilling mud to fill the drill hole . The active surface system will be divided into 2 parts : solids removal and addition suction parts . The solids removal equipment and degassing will be happen in solids removal parts like shale shaker , vacuum degasser , mud cleaner , etc . The addition suction part use adding fresh mud to the circulating system by mixing hopper and mixing pump and provide sufficient residence time for mixing together before mud being pumped into downhole . The slug tank normally use to pump small pills like LCM or barite slugs and each section further divided into enough compartment .

The equalisatio height between mud tank compartment is depend on the duty of the tank compartment . There is a rule that an adjustable equalizer will be need between the solids removal part and addition suction part . There are different mud tank compartment , the sand trap is the compartment under shaker to keep drilling mud after shale shaker . It should be the only settling compartment and preferably should not be used in closed toopsystem . There sand trap floor should have a 45 degree slope to its outlet for selfcleaning and 20 to 30 bbl size capacity .

 

The solids removal equipment will be arrange to remove different size of solids . Shale shaker is the first phase cleaning for bigger drill cuttings ,desander will be sit after shaker to separate sand out and desilter sit after to separate silt out . The decanter centrifuge will be installed depending on drilling condition for 2 to 7 microns separation of fine solids .

GN can offers customized solutions on the drilling waste management  field Welcome you contact GN group freely for solution.

 

While in complete steps of solids control, mud cleaner is the combination of second and third steps of the mud processing steps.  It is the combination of desander hydrocyclone, desilter hydrocyclone  and the shale shaker for treating process of the drilling fluid.  The main structure of the mud cleaner is define in two parts.  The upper parts are desander hydrocyclones and desilter hydrocyclones that shoot our solids to bottom parts of mud cleaner which is shale shaker.  This combination have the advantage of space saving and operation cost saving.

Drilling fluid mud cleaner is a filtering equipment of solid control purification system. Mud cleaner is composed by inlet, outlet pipe and hydrocyclones. Hydrocyclone is made of PVC, upper cone, and under cone. The overflow line, inlet line and outlet line is fixed by the clamp. The bottom inject outlet can be adjusted and changed it according to drilling cutting in drilling fluid. When adjust the bottom flow mouth, only need screw out the adjusting spray result. Screw on the adjusting spray after changed the bottom flow sand removal exit. The both side of desander are equipped the inlet mouth, when choose the side, the other side need to cover off by blanking cover.

Drilling mud enter into the hydrocyclone inner wall from the feeding of the  hyrocyclone mouth, then tangential enter into hydrocyclone cyliner with high spinning speed will produce the enormous centrifugal force field, the light drilling mud spin upper from the central low pressure areas, and discharged to drilling fluid circulating tank from the overflow exit. The heavy solid phase particles are throw to the cylinder wall by the centrifugal force, which is spiral sinking under the action of the thrust drilling fluid downward spiral and discharged from the bottom flow mouth, the flow to the screen surface.

In a complete oil and gas drilling solids control system, there is not only main equipments like shale shaker, desander, desilter, mud cleaner, and decanter centrifuge, there are also auxiliary equipments that play certain roles in the whole procedure, like the mud agitator, mud guns and mixing hoppers, and also the pumps for feeding including centrifugal pumps, submersible slurry pumps and shearing pumps.

The auxiliary equipments’ performances also affect the treating efficiency for the whole system. GN Solids Control, as the TOP solids control manufacturer in China, always sticks to its belief: Quality first, Price second. Even the mud guns, GN Solids Control also provide the best ones.

GNNJQ series mud guns have following main benefits:

1. for the mud gun nozzles, GN use polyurethane as material, for a better wear proof result and a longer service life. Unless other Chinese suppliers, who mostly use the metal like steel for the nozzle material, Polyurethane is for sure a better choice. Just like the hydrocyclones for desander or desilter, before, the manufactures all use steel ones, but now the high standard solution is the polyurethane ones, the service life is greatly prolonged.

2. GNNJQ series mud guns also suitable for higher pressure condition, its largest pressure is up to 6.4Mpa, which is the standard of high pressure mud gun. GN use this as standard level in order to provide more cost-effective choice for the clients, and of course, the safer usage.

3. the main body of the mud gun is made of national standard steel from reliable supplier. GN Solids Control always buying from large supplier with good reputation.

 

For other GN products also, like the bearings, GN uses SKF, FAG or NSK, the vibrating motors for shale shakers, GN uses Italy brand Oli or USA brand Martin. And for the design and manufacturing, GN has 10 patents already and another 5 pending. And GN QC department is always serious in inspecting the semi-products and products.

The technology of trenchless digging is developed from directional drilling technology, require very small area of surface for the construction.  it only needs very small inlet and outlet area excavation. All kind of underground replacements of the pipeline construction start adopt this technology for minimum interference of surface have high effect of keep the cost in control.

In 1970’s the technology was developed and now is widely use on horizontal directional drilling, piping, tunnel digging, piping type of detonation are some use this method.  Now are widely use in water supply and drainage.  Laying power, gas, communications lines. Any type of pipeline construction and repair of old pipeline.  The archaeology use this method of digging to minimal disturb the ancient structures.

Horizontal directional crossing (HDD-Mud Recycling System) technology in oil and gas industry are laying pipeline across waters like river and lake.  The hub of railroad obstacles and areas has important function  that cannot be disturb is obvious using through Horizontal Directional enlarge hole that common diameter of pipe in 1.5 times larger.

The method of solids control principle used in Horizontal directional drilling is the control of mud solid phase technology.  The technology purpose remove the harmful mud, solids and keep the good solids through process on mud filter and cleaning requirements.  The current use of horizontal directional drilling, the recovery mud solids control is system composed from small to large as end user requires.  The choices of mud solids control system is need according the basics in below:

 

It needs to be clean or inhibit particle variable types and size

It need to be maintain the quality of the mud

The size of ability in drill, removal of solids and operation cycle rate.

 

Solids control system function as environmental protection system that is requires in every region of the world who are digging in to earth to harvest resource underground.

It is known to all that for the oil and gas drilling projects, there must be a solids control system for separating out as much as solids cuttings, but in HDD projects, in many places in the world, the separation unit is not a legal request.

Recently, more and more countries are establishing laws requesting the mud recycling system or mud recycling units, and some clients, although their countries have not yet established such laws, the company owners decided to use mud units for their drilling works, because of below benefits a mud unit provide:

1. greatly save the usage of materials, including water, bentonite and polymer

2. save the drilling cost by lower down the discharge disposed.

3. responsible for the surrounding and environment friendly.

What’s the main equipments for a HDD mud system?

For a high standard configuration, there are 3 steps separation and 1 step of mixing, the separation equipments include: 1. Shale shaker, 2. Desander, 3. Desilter. In order to save space and make the mud unit more compact, there is always a mud cleaner playing a role as combination of desander and desilter. And mixing system is a jet mud mixer consisted by a mixing hopper and a centrifugal pump for feeding.

Of course, per different jobsite condition and composition of mud, end users could change the solution, some use without desander, some without desilter. And some adds equipments for a further and cleaner separation with a decanter centrifuge and even a dewatering unit.
