GN Is a manufacturer Petroleum Drilling mud Solids Control Equipment and system, we supply effective and a whole series of drilling mud Solids Control Equipment.

Petroleum Drilling mud Solids Control Equipment is a complete system which can be purchased as a whole or piece by piece as the user can afford to upgrade his system.

The LINEAR MOTION shale  SHAKERS will affect mud costs, make running polymer muds feasible and reduce liquid waste.

When used along with a DESANDER the drilling mud can be used to drill massive shallow sands without overloading the drilling mud system with abrasive/coarse solids. This prevents excessive density and viscosity which would necessitate dumping volume to make room for dilution.

A third shaker and desilter, consisting of a bank of 4” desilting  cones will further control the build up of solids and reduce the amount of liquid wasted substantially. However, on deeper wells and those with troublesome shale a build up of solids less than 70 microns will result in deteriorating mud properties, which again will necessitate dumping volume to make room for dilution.
With the inclusion of a decanting centrifuge, the closed loop system will allow the removal of solids from 2 microns up to 70 microns. Mud density can generally be controlled for long periods in an unweighted (no barite) system.

The future path of GN Petroleum Drilling mud Solids Control Equipment will continue to increase the overall removal efficiency of undesirable solids from the drilling mud. This will include continued improvements in shale shaker and screen life. Research investigating alternate technology such as using vacuum techniques and different motions.With our talented engineering,they will use the leading Petroleum Drilling mud Solids Control Equipment technology to design, size and operate solids removal equipment properly. And provide end users with proper use of the equipment,and other technique help.And use the technology to carry out GN solids control 3P concept:  Produce first-class products for customer,Provide over-expected service for customer,Pursue unlimited value for customers.We strive to make the world class Petroleum drilling mud solids control system equipments.

About fixing your existing system,our engineers have reviewed your pictures and the desilter drawing,from our experience,the desilter we offer you as in the quotation (GN.8.28 existing system Quotation)will match your existing system.We have ever sold many mud cleaner,desilters,desander for our customer to update or fix their existing system.

What you need to do to fix your existing system is that you get the customized desilter from us,and link the pipes with it,it’s simple work for engineers.

If you provide the CAD design drawings for your existing system,we will be able to provide you another improved CAD design drawing for your system with details how to install the desilter we offer you.That would also make you more clear about whether our desilter will match your existing system.

We just sent out a small drilling mud processing  system to our Kazakhstan customer.We enclosed the picture and drawing for your info.

Our sugesstion for fixing your mud recycle system  is as below:

1,With the above info,If you are still not sure about how to fix the existing system,pls provide your existing system CAD drawing,we design a new install CAD drawing according to it with our new desilter designed for you.

2,If you are not able to provide the existing system CAD design drawing,and you need us to pay a visit to look at your system,it’s our pleasure to do it.But we usually do this at our customers expense,the cost including:airline ticket,accommodation etc.

Pls give us your choice,or if you have any questions,pls let us know.

Jessie ,    The biggest problem ( weakness ) with our system is the bottom shale shaker screen which is used for scalping . Even if we run very course screens (50mesh) with say 50US gpms running over it the material comes off wet ( liquid like ) . The drying screen at the top seems to be ok most of the time which we run our 6 x 3″ cones over . The top screen we usually run 150 – 210 mesh screens .

We think our vibrating G forces are not correct , they are 1.5hps motors set with on 100% counter weights .

I think we need flat screen technology with wedges similar to the kemtron models and have 3 decks
The two lower decks being scalpers and top deck a during screen under your six cones .
The basket needs to fully adjustable .
We need to pump very heavy mud at 200 US over the scalping screens to fix the problems .
Our desilt pump will handle 6 4″ cones
How many US gpms will the system in the picture process over the scalper shale shaker screen .

Please find the drawing of our existing mud recycle system . It does not have dimensions but this should give you a better idea .

The mud equipment system designed included everything between the bell nipple and the mud pumps,as well as the waste handling system. The assumption was that this rig would be used for several years so almost any reasonable investment in mud equipment would be paid back many fold. In addition, the system was somewhat over-designed, as it is easier to remove a piece of equipment than to add one. The design process focussed on the horizontal sections as that is where the most challenging solids removal situations would occur. The system was designed according to accepted oilfield practice for efficient and effective solids removal from drilling fluids1, 2, 3. The system design needed to account for the following needs and concerns:

Shale Shakers China shaker screen Supplier

• The main goal of the mud equipment and waste

handling system is to maintain drilling fluid properties and

minimize waste haul off without slowing down the

drilling process.

• The dry locations require haul off of drilled cuttings

and waste mud. The system design needs to strive

for minimum of haul off by yielding cuttings in as dry

a state as possible and for a minimum of mud

dumping and dilution to maintain properties. These

goals will help minimize costs by minimizing waste

volumes (cuttings and mud) that require trucking and

disposal.

• With the dry loWith the dry location, no sand trap (settling pit)

would be used in the mud handling system.

• Use a pad rig with a fully mobile mud system to

eliminate the use of transfer pumps that caused

problems for other operators.

• With the fairly coarse sand to be drilled, the shale

shaker can be the heart of the mud handling system. However, if

screen blinding is a problem and coarse screens are

required, then a great deal of the sand cuttings will

pass through the screens.

• If coarse shale shaker screens are necessary, then the

hydrocylones desander ,desilter will become the heart of the system.

Sufficient capacity will be required to process the

sand at expected drilling rates without overloading.

• The low drilling  mud weight requirements and dry discharge requirements necessitate that the cones be operated as efficiently as possible and that the cone underflow be centrifuged.

Drilling mud equipments and systems usually including,shale shakers,mud cleaner,vacuum degasser,decanter centrifuges etc.All this equipments are designed for oilfield drilling and can protect the safty of drilling waste handling system.

We manufacture drilling mud management decanter centrifuge including any speed of decanter centrifuge,high speed

decanter centrifuge,low speed decanter centrifuge.

More over,we can design and manufacture a whole drilling mud management system.With the most suitable decanter centrifuge.

Because there are such a variety of both standard and unique applications, choosing the correct decanter centrifuge is often more of an art than an exact science. Determining the correct machine style and model size requires a thorough understanding of the application and very often sample testing. The more a customer knows about their process and the results desired, the more helpful it is. And when a customer calls or e-mails, we would initially focus on determining the following:

• Description of the liquid phase and the solid phase for the drilling mud management system.
• Total liquid volume of the system and amount of available process time and / or required process flow rate
• Quality of required liquid phase / phases – targeted concentration of impurities
• Amount of solids that need to be removed from the given liquid volume
• Targeted dryness of the solids
• What the customer wants to achieve

Decanter centrifuge in the drilling mud management system are used after the mud Cleaner.As we know the first stage we use shale shaker,and the second,we use mud cleaner.For some drilling mud management system ,we also use vacuum degasser.

From this simple calculation we can often quickly determine which style of liquid / solid separation is most applicable for the application. A further simple lab decanter centrifuge test determines the most appropriate type of decanter centrifuge, whether it fits the customers thinking, and if it is within the expected customer budget.

Welcome to consult us about drilling mud processing system design.Free Drilling mud processing system design service.

I read an artircle about drilling mud system design expirence,and share with you below:

When the Hamaca project was begun, there were already three operators working on heavy oil developments in the Faja: Petrozuata, Sincor, and Cerro Negro. Before the Hamaca project was started, these
operations were visited to help determine current best practices and problems that needed to be addressed.Each of these operators use pad drilling rigs, which are rigs that are designed to move quickly from well to well on a multi-well pad. These rigs use stationary mud processing systems (see picture) that are connected to the mobile rig by flexible umbilicals. The flow line shale shakers and one mud tank (sand trap plus one compartment) move with the rig. The mud is pumped from this pit through an umbilical to a stationary tank where the fluid is processed by various desilter,desander hydrocyclones,mud cleaner, and decanter centrifuge to clean the mud. The clean mud is pumped back to the rig through umbilicals.

Simple fresh water-based mud is typically used in the 12-1/4 inch intermediate section. Hole cleaning in the curve is the main concern, and xanthan biopolymers are used to enhance hole cleaning.There were basically two different drill-in fluid systems inuse in the Faja for drilling the 8-1/2 inch section. One is a very typical water-based drill-in fluid with xanthan biopolymer for rheology control, starch for fluid loss control, calcium carbonate for bridging, and biocide. The other system is solids-free: simply xanthan biopolymer and biocide.

Industrial decanter centrifuges are wildely used In oilfield drilling fluids solids control systems.It is used after the mud cleaner or desander desilter for seprating drilling cuttings.We are A China based oilfield industrial decanter centrifuge manufacturer.

How Does An Oilfield Industrial decanter Centrifuge Work?

A decanter centrifuge works by spinning a vessel containing the material to be separated at high speed. It is very much like the rides at the fairground that rotate. You have to lean towards the center to overcome the force caused by the rotation. In fact, some rides are designed specifically to press your body against a back support. The decanter centrifuge spins at very high speeds and pushes the ‘heavy phase’, usually the solids, to the outside of the vessel, just as you would see in the clear flask standing on the bench top.

What Is The Oilfield decanter Centrifuge Process?

In the drilling mud purification system,If you take a sample of the liquid / solid mixture in a clear flask and you observe that there is a separation of the two phases with time, the separation is caused by the force of gravity. The oilfield decanter centrifuge process speeds up the process by increasing the force of gravity 1000 to 4000 times, depending on the solids control equipment. The result is that a process that can take 1-12 hours in a flask is achieved in seconds using centrifugation.,

By the way,we also manufacturer shale shaker

For separating solids from liquid ,Basicly ,processes used for the separation of suspended solids from a liquid media:

• Sedimentation
• Filtration
• Centrifugation

Sedimentation Equipments(Silting mud tank), allows solid particles, which are heavier than the liquid media, to separate and sink to the bottom of a container under the influence of gravity.In drilling mud solids and fluids separation,we usually use silting tank bogether with need equipments to separate solids from drilling fluids.

Filtration equipments( Shale Shaker) incorporates the use of a filter media by virtue of its degree of porosity and regulates what may pass through it. Since the filter media collects suspended solids, the material progressively builds up and will eventually impair performance and require removal, cleaning, and / or replacement.In the solids control system,there are three equipments use this way,Shale shaker,mud cleaner,and the desilter desander.

Multiply the power of gravitational force by more than 2,000 times.

Centrifugation Equipments (Decanter centrifuge) is a highly accelerated form of sedimentation. This rapid form of sedimentation is attained by introducing centrifugal force to the liquid / solid media generating a force that can be over 2.000 times more powerful than gravity itself. This method is fast and eliminates the need for filter media. GN decanter Centrifuge’s complete range of liquid / solid separating centrifuges are designed to separate suspended solids heavier than the liquid media without the use of consumable filter media.

We are a China manufacturer of Liquid  Solid Separation Equipments
