In oilfield drilling mud separation,The larger the centrifugal force, the finer the separated solids, so three types of speed decanter centrifuge can get according to separating factor.

oilfield decanter centrifuge

a)     Low-speed oilfield decanter centrifuge: it is also called “barite recovery” centrifuge. Its separating factor is 500~700. To low-density solids, its separating point is 6~10μm. To high-density solids, its separating point is 4~7μm. This kind of centrifuge can be used for recovering barite.

b)    Medium-speed oilfield decanter centrifuge: its separating factor is 800 or so, solids of 5~7μm can be separated, so harmful solids can be separated from the mud, so that gravity and viscosity of the mud can be controlled. Most drill team will choose this kind of centrifuge at present.

c)High-speed oilfield decanter centrifuge: its separating factor is 1200~2100 or so, separating point is 2~5μm, it can remove harmful solids, control mud viscosity, it is usually connected with low speed centrifuge to make up a dual centrifuge system(See figure 3). In the system, low-speed centrifuge is installed at the first grade, barite separated
from it is discharged into mud tank to be recovered, liquid is drained into a surge drum first, and then be sent by a pump to high-speed centrifuge; the solid separated from high-speed centrifuge will be discharged out of the tank and the liquid is back to recirculation system. “Dual centrifuge system” can remove

Shale shaker screen

r

API RP 13C is a new physical testing and labeling procedure for shale  shaker screens. To be API RP 13C compliant, a shaker screen must be tested and labeled in accordance with the new recommended practice.

Shale Shakers China shaker screen Supplier

Great disparity and performance in screens throughout the oil and gas drilling industry. But now With API RP 13C, API RP 13C is here. So you know exactly what you’re buying!

• Two tests were devised: cut point and conductance. The tests describe a screen without predicting its performance and can be performed anywhere in the world.
• After identifying the cut point and conductance, complying with API RP 13C requires application of a permanent tag or label to the screen in a position that will be both visible and legible. Both cut point expressed as an API number and conductance shown in kD/mm are required on the screen label.
• Internationally, API RP 13C is ISO 13501 for screens

The new procedure is a revision of the previous API RP 13E, which was based on optical measurements of the screen opening using a microscope and computer analysis. Under API RP 13E, screen designations were based on individual manufacturer test methods, producing inconsistent labeling.

After identifying the cut point and conductance, complying with API RP 13C requires application of a permanent tag or label to the screen in a position that will be both visible and legible. Both cut point expressed as an API number and conductance shown in kD/mm are required on the screen label. Previously, screens were labeled in accordance with manufacturer specifications.

Drilling mud decanter centrifuge

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.

1，Can you adjust the deck angle on your shale shakers ?
The shale shaker deck angle adjustment is: 0°～3°, following picture is an unfinished equipment we are making for our indian customer,we will give you the tool for adjustment.

2,Can the top screen be the same size as the bottom or is this not necessary ?
This is not necessary,actually,we design it according to your treating capacity,for yours,the top screen is smaller than the bottom screen.

I will probably have more question later .

Thank you very much for your help and I hope we can do business together .

SEPARATION by VIBRATORY SCREENING
One method of removing solids from drilling mud is to pass the mud over the surface of a vibrating screen. Particles smaller than the openings in the screen pass through the holes of the screen along with the liquid phase of the mud. Particles too large to pass through the screen are thereby separated from the mud for disposal. Basically, a screen acts as a “go-no-go” gauge:  Either a particle is small enough to pass through the screen or it is not.
Screening Surface. Screening surfaces used in solids control equipment are generally made of woven wire screen cloth, in many different sizes and shapes. The following characteristics of screen cloth are important in solids applications.
Screens may be constructed with one or more LAYERS. NON-LAYERED screens have a single screen cloth mounted in a screen panel. These screens will have openings that are regular in size and shape. LAYERED screens have two or more screen cloths, usually of different mesh, mounted in a screen panel. These screens will have openings that vary greatly in size & shape.
Mesh is defined as the number of openings per linear inch. Mesh, can be measured by starting at the center of one wire and counting the number of openings to a point one inch away.

SIZE OF OPENING is the distance between wires in the screen cloth & is usually measured in fractions of an inch or microns.
Screens of the same mesh may have different sized openings depending on the diameter of the wire used to weave the screen cloth.

The smaller the diameter of the wire results in larger screen openings allowing larger particles to pass through the screen. The larger the diameter of the wire, the smaller the particles that will pass through the screen Remember: It is the size of the opening in a screen not the mesh count that determines the size of the particles separated by the screen.
PERCENT OF OPEN AREA: is the amount of the screen surface, which is not blocked by wire. The greater the wire diameter of a given mesh screen, the less open space between the wires. For example; a 4 mesh screen made of thin wire has a greater percent of opening than a 4 mesh screen made of thick wire.
The open area of a non-layered, square or oblong mesh can be calculated and should be available from your screen supplier.

Drilling fluid is classified as water base utilizing water as the liquid phase. The solid phase of any drilling fluid is either commercial solids or drilled solids. Most commercial solids such as bentonite have a relative particle size of less than one micron. (.000039 inches).

Drilled solids are those particles that enter the mud system in the form of cuttings from the bit or back reamer or from borehole debris. These solids vary in size from less than one micron & larger depending on the carrying capabilities of the drilling fluid. Note that spindle speed and the amount of push or pull force require to drill play an important factor on the particle size of the cuttings.
One of the most important objectives in solids control is to remove as many of the large particles as is practical the first time that these solids are pumped out of the borehole. This requires properly designed and installed solids removal mechanical treating equipment sized to process a minimum of 100% up to 125% of the mud circulation rate. Solids that are not removed during the first circulation through the surface equipment are subjected to mechanical degradation by the drill bit, reamers and mud pumps during each circulation cycle until they are too fine for removal by mechanical means.
In order to evaluate the removal capabilities of the various pieces of mechanical treating equipment, it is necessary to consider the source of the solids and classify them according to the following sizes:
440 microns or larger   large drilled solids (*cuttings) By Shale Shaker
74 to 440 microns sand   Be separated by Desander in drilling fluids circulation
2 to 74 microns  silt       Be separated by Desilter in drilling fluids circulation
0.5 to 2 microns clay     Be separated by decanting Centrifuge in drilling fluids circulation
0.5 microns & smaller  colloids

Note:  ( .001 inches = 25.4 microns so 1” = 25,400 microns )
