SHALE SHAKER SCREEN

Shale shaker is the kernel device in any solids removal program. Screens as the most cost spare part of shale shaker are very concerned by engineers. For maximum efficiency, the solids on the screen surface must  travel in a predetermined pattern — spiral, elliptical, orbital or linear motion — in order to increase particle separation efficiency and reduce blockage of the screen openings. So both screen cloth and frame must be reliable to fit different solids in various drilling circumstances. Generally, the materials of screen cloth is stainless steel and polyurethane. There mainly has two materials component screen frame: steel, composite frame.
We, Aipu solids control has 15 years experience manufacturing shale shaker screen. Our Screen has been tested under API RP13C. We are only China screen manufacturer got API RP13C compliance report. Trust the accurate cut point will lead better performance and longer service life of screen.

Screen Cloth

Long screen life, high separation efficiency and low cost is the key factor when buy shaker screens

shale shaker screen mesh manufacturing

There are mainly two materials used in shale shaker screens today.
1. Stainless steel wire (S.S304 ~ S.S316L).
2. Polyurethane wire.

Screens may be constructed with one or more Layers. Non-layered screens have a single layer, finemesh, screen cloth (reinforced by coarser backing cloth) mounted on a screen panel. These screens will have openings that are regular in
size and shape. Layered screens have two or more fine mesh screen cloths, usually of different mesh (reinforced by coarser backing cloth), mounted on a screen panel. These screens will have openings that vary greatly in size and shape.

There are several types of wire cloth used in the manufacture of oilfield screens. The most common of these are Market Grade (MG), Tensile Bolting Cloth (TBC), Triple Layer Super Fine (TRSF or DX) and Extended Rectangular (ER). These are square mesh weaves, differing in the diameter of wire used in their construction.
MG: Single Layer Screen Mainly used as a scalping screen.
TBC: Single layer Tensile Bolting Cloth over a heavy support mesh Well defined cut point Poor blind resistance.
TRSF/DX: Two superfine layers over a heavy support cloth Good screen life Good blind resistance.
XR: Two oblong-aperture cloth layers supported by a square mesh High conductance Long life Good blinding resistance.

Screen Capacity, or the volume of mud which will pass through a screen without flooding, varies widely depending on shaker model and drilling conditions. Drilling rate, mud type, weight and viscosity, bit type, formation type, screen mesh — all affect throughput to some degree.

To increase screen capacity without increasing the size or number of shale shakers, three-dimensional screen panels are available. 
3-D screen panels increase the usable screen area of a screen panel by corrugating the screen surface, similar to the surface of a pleated air filter or oil filter. 3-D screen panels are most effective when installed as the submerged, feed-end screen on linear-motion shakers to take full advantage of the additional screen area. Past the fluid end point, a three-dimensional screen tends to “channel” the drilled solids and increases solids bed depth and the amount of liquid carried off the screen surface. Using a flat screen at the discharge end of the shaker eliminates channeling, increases cuttings dryness,
and decreases fluid loss. Typically 3-D screen is Pinnacle™ shaker screens replacement.

Standardization of screen cloth designations has been recommended by the API committee on Standardization of Drilling Fluid Materials. The purpose for this practice is to provide standards for screen labeling of shale shaker screen cloths. The procedures recommended for labeling allow a direct comparison of separation potential, the ability to pass fluid through a screen, and the amount area available for screening.
The API screen labeling includes of the following:
1. Manufacturer’s designation;
2. Separation Potential and
3. Flow Capacity.

Shale Shaker Screen's Question And Answers

There are some questions of shale shaker screens may confused among users. Here's answers

What is the D100 and how is it related to the API screen designation?

The D100 value represents the diameter of the coarsest particle (in microns) which will pass through the screen during a dry laboratory test and is a single number, not a range of sizes.
The API screen designation for a screen is the API-defined range of sizes into which the D100 value falls. Some of the coarser size classes span quite a large range of D100 values. 

What does/doesn’t the D100 tell us?

The D100 value is the finest particle diameter at which the screen no longer sends 100% of the particles to the discard stream. This is also the coarsest particle that will pass through the screen.
The D50 value is the particle size at which the screen sends 50% of the particles to the “overs” (discard), while the remaining 50% report to the “unders” (undersized stream) and the D100 should not be compared in any way. The D50 was interpreted as the micron size where a screen makesa 50/50 split.
The API RP 13C D100 is a very specific value determined from a carefully-controlled laboratory procedure so that any laboratory should measure the same value for any given screen cloth. 

Will a screen with a D100 of 110 microns remove solids finer than 110 microns?

Yes, more than half of the particles that are coarser than D50 and finer than D100 will report to the overs. A significant portion of the particles finer than D50 will also report to the under. (By definition, every particle classified in the D100 size or coarser will report to the overs as expected.)

Should I use the old screen number or the new API screen designation when ordering replacement screens?

Aipu intends to remain completely flexible and will accept orders according to the system that customers prefer. Orders may be placed using either the old nomenclature or the new API screen designation.

What is the practical value of the new API RP 13C screen labeling practice to the end user?

The new API RP 13C labeling practice provides an excellent standard and benchmark for comparing one screen manufacturer’s screen separation against another. The closer the D100 values, even within the same size class, the better the comparison will be.
Aipu will work with customers to ensure that screen comparison tests are performed in a fair manner to both the competition and to Aipu, allowing the development of a balanced test plan, including a double-blind particle size analysis protocol, whenever a screen comparison is to be conducted. 

Why is there such a great variance between the old and new screen labeling values?

The biggest variation is due to the shift from the D50 value to the D100 value.
The previous test procedure for screens, API RP 13E, measured the distribution of the screen holes as measured by light, not solids. Subsequently, the screens were labeled using the D50, D16 and D84 separation curve.
The current test procedure, API RP 13C, measures the coarsest particle which passes through the screen, using a much more accurate and repeatable test method. The screens are now labeled using the D100 size criteria. 

Why maintain shaker screen?

Maintaining your shale shaker screens is as important as the screen selection itself.

Any screen’s service life can be maximized through proper selection and maintenance. Proper screen maintenance starts with regular inspections. Look for tears, signs of blinding, and gaps between the screen mesh and frame. 

For example, if your inspections  show that a screen typically lasts 9 weeks, you can change  the screen after 7 or 8 weeks during scheduled downtime  and avoid the interruption to your process. Or, if your material  has corroded the screen, you can replace it with a  screen made of mesh of a different steel alloy or a synthetic
material.

After inspecting the screen, clean it off if needed. The cleaning method will depend on your material and process and can range from light brushing of dry, lightweight particles to power-washing of heavy or cohesive particles from the screen.

How to select screen mesh and steps of maitain?

Usually, when the shale shaker is first stage solids control equipment the shaker screen can be 30-100mesh. When the shale shaker is a part of mud cleaner, the shaker screen for the cleaner will be 80-200mesh then.

Of course, the selection is relative with drilling mud property and our working condition at the drilling job site.

Replacement screen steps:

1) Before every shut off, the shaker should run without any medium for 5-10 minutes, at the same time, use clean water to flush screen clean
2) After every operation, the shaker frame and screen should be flushed by water (summer) or steam (winter), there should be not much sediment on shaker frame and shaker screen. Especially when the drilling mud has large viscosity and high density or screen is finer than 60 mesh.
Otherwise, the particles and fine sand on screen will block screen hole, when we start shale shaker, it will decrease filtration result and lead drilling mud flow away, lose much unnecessary cost 

How to replace shale shaker screen?

During operation, while the screens are broken , or cannot separately well, it then should be replaced by other shaker screen. Aipu shaker screen can make high quality shaker screens for its own brand shale shaker as well as other famous brand. And also, Aipu can customize screens according to clients certain requirements.

Troubleshooting screening problems

Upper screen opening too small Select an upper screen with a larger opening.
Lower screen failedCheck lower screen for holes or tears
Lower screen opening too largeSelect a lower screen with a smaller opening.
Screen blindingWire diameter too heavySelect a screen with a lighter wire diameter.
Worn sliders or ballsCheck antiblinding devices and replace them as needed.
Screen blocked with materialClean or replace screen.
Screen overloadedReduce feedrate.
Short screen lifeWire diameter too lightSelect a screen with a heavier wire diameter.
Improper handlingBe careful not to crease or dent screens during handling or installation.
Screen overloadedReduce feedrate.
Screen corrodedInstead of stainless steel wire mesh, try alternative alloys or use a screen made of a synthetic material.
Screen blinding occurs when some or all of the screen’s  open area is blocked by mud. This may be caused by a  too-high feedrate that solids onto the screen  faster than the screen can operate. Or it might be caused by  poor screen selection — for example, choosing a screen  with too heavy a wire diameter. Or it might be caused by  your mud’s characteristics, such as cohesiveness.  Blinding is often behind a gradual degradation in your  shale shaker performance.
