Drilling cuttings decanter centrifuge at the jobsite

GN solids control already offered over 250 models drilling cuttings decanter centrifuge around the world, here is a photo of GNLW363VFD decanter centrifuge at the jobsite. Besides of the decanter centrifuge, this client also utilized our screw conveyor to gather the drilling cuttings and transfer them. Screw conveyor is specifically utilized for drilling cuttings moving among the drilling waste management system, particularly for the drilling cuttings with fewer liquids, the performance of transfer is demonstrated much better than other moving techniques.

Probably the most important feature of the screw conveyor quality is that the bearings and screw propeller; it’s frequently used flat or in a slight incline to transfer the types of materials. GN always choose renowned brand bearings for such essential components, so we provide various options of screw material as customer’s requirement, even the screw conveyor length also can be customized, we’ve various sections with every section 12ft length.

Normally our client can make a higher and adjustable frame in your area for their only project; they will put our decanter centrifuge around the frame. Our decanter centrifuge can be used the programs below:

1 water drilling liquids dewatering centrifuge

2 barite recovery centrifuge in solids control system

3 decanter centrifuge for top gravity and occasional gravity solids

4 drilling cuttings treatment system

5 waste water treatment

The most crucial problem within the jobsite operation is maintenance, with higher and proper maintenance; the decanter centrifuge can function perfectly. Here is the instructions ought to be compensated more attention for that centrifuge operation.

1 cleaning after each time operation by water or drilling liquids

2 lube based on GN recommend lube chart

3 tighten the security guard belt before shipment, and take away it before start

GN professional engineer will fly for your jobsite to train your operator that helps for brand spanking new commissioning service.

The Introduction on the Drilling Liquids

Drilling liquids has become broadly utilized in oil, gas drilling along with other drilling mud system. Using the solids control equipment, the drilling liquids might be recycled many occasions for cost saving and atmosphere protection. This short article gives an easy introduction around the purpose of the drilling liquids.

What’s the purpose of the drilling liquids?

1. Eliminating bottom from the well our prime pressure drilling liquids get out of the drill bit would flush the foot of the well make no obstacles for drilling process.

2. Carry cuttings – the drilling liquids would go ahead and take drilling cuttings to the floor surface for mud cleaning process.

3. Balance formation pressure – because of the very deep drilling, the drill bit can experience different formations for example rock formation and ground water formation. The drilling liquids here performed to avoid the floor water stepping into the drilling well. This could safeguard the geological structure.

Besides, the drilling liquids may also function to awesome lower and lubricate drill bit, safeguard borehole wall and supply downhole energy.

To completely have the drilling liquids advantages, you will find several needs around the drilling liquids.

1. The drilling liquids should meet interest in drilling mud recycling

Drilling cycle request the drilling liquids low pump pressure (low fluid viscosity), excellent capability to carry cuttings (dynamic pressure is high), low beginning pump pressure (low static shear pressure), good lube performance, low friction (less solids contaminants)

2. Keep up with the stability of borehole

It’s asked for to make use of drilling liquids column to balance the development pressure. So when drill oil and gas layer, the drilling liquids can also be required to balance pressure from the oil and gas. That will request a reliable density from the drilling mud.

3. Oil and gas protection

After drilling oil and gas layer, drilling fluid contacts with oil and gas. To avoid drilling fluid harmful the oil and gas layer, the drilling liquids ought to be small filtration, thin mud cake, low solid content and occasional filtrate of hydration etc.

4. Safeguard the character atmosphere

Drilling fluid frequently consists of oil and oil, diesel oil and a lot of chemical agents. To be able to avoid the possible effect on character atmosphere, non-toxic, harmless drilling liquids ought to be used.

Oil-base fluid course of treatment allows reuse of costly liquids

The GN-USE process is really a patent-pending technology that enables operators to reuse invert emulsion drilling liquids over multiple wells without depending on reclamation through high rates of dilution. The procedure goodies oil-base drilling fluid, reducing solids below 1% while drilling.

Before the development of the GN-USE technology, combating the build-from ultra-fine, low-gravity solids needed using dual Decanter Centrifuge and dilution. Using the GN-USE process, staged centrifugation supported by chemically enhanced treatment renders both LGS and drill solids workable. The machine may be easily modified to create relatively ‘dry’ clippings, reducing drilling wastes.

Combined mechanical/chemical process removes low gravity solids

Conventional mechanical separation techniques are not able to extract ultra-fine low-gravity solids from an oil-base drilling fluid, needing operators to dump the costly fluid. The chemically enhanced GN-USE process continues to be area-proven returns the fluid towards the loop in the same weight because the dirt was initially built. Following the dirt operates within the drying out shakers, a minimal-speed centrifuge constitutes a separation then returns the barite slurry using the large LGS contaminants to the dirt system. This slurry is modified to complement the initial dirt weight.

The liquid phase in the low-speed Solids Control operates for an effluent tank where it’s polished utilizing a mid-speed centrifuge. Base fluid is added before the target volume is met. Then your fluid is undergone our prime-speed centrifuge and also the GN-USE chemicals are put into further take away the LGS. By delivering clean fluid, GN-USE technology also significantly enhances drilling performance.

Reduced waste equals reduced well cost

The GN-USE process provides tremendous savings in dirt-related costs, including reducing the quantity of solids-laden liquids moved for disposal. By reduction of the quantity of LGS within the fluid, the GN-USE process also reduces the quantity of dilution needed to come back the drilling fluid to some functional condition. This protects on assets, for example barite, base liquids and chemicals connected with building invert emulsion drilling liquids. Top quality barite is progressively scarce and costly. The GN-USE process allows operators to lessen the amount of barite along with other materials within their fluid systems, supplying 25-30% savings.

Simple process using easily available equipment

While using easily available Compact disc-500 centrifuge, the GN-USE process constitutes a separation from the fluid in the LGS using low speed centrifugal separation. The slurry will be balanced to complement the load from the dirt system. When the slurry is incorporated in the effluent tank, it’s pumped towards the high-speed centrifuge, that is typically set around 2,400 revolutions per minute. Base fluid might be added at this time to assist lower the plastic viscosity. Another pass within the centrifuge, this time around at 2,900 revolutions per minute, robotically cleans the effluent just before caffeine stage.

A single tote chemical that consists of dual surfactants along with a polymer inside a water-based company is added. When the clippings are water-wet, they create a charge. The polymer covers them and results in the ultrafine solids to develop to some size that’s readily detachable with a final go through our prime speed centrifuge at 2,900 revolutions per minute, producing a fluid that may be came back towards the primary drilling fluid system free from low gravity solids.
