What does Shale Shaker Screen mean?

A Shale Shaker Screen is a component of a drilling rig that acts as the first point of contact or first phase by which drill cuttings come in contact while entering into the shale shaker equipment. A shale shaker is a solid separation tool that helps in the removal of the large portions of cuttings from drilling fluids. Shale shaker screens are important to the shale shaker equipment used in the mining, oil and gas and coal cleaning industries for grinding and controlling drill cuttings from mud.

A typical shale shaker tank consists of the following components:

-Hopper

-Feeder

-Screen Basket

-Basket Angling Mechanism

-Vibrator

Shale shaker screens come with a variety of frames such as steel frames, composite frames, hook strip flat type screens, pyramid shaped screens, etc. The specification of a shale shaker screen varies as per the mesh size and the mesh size is designed as per the various API screen number specifications. For example, mesh size >7801.0 TO 925.0 microns is designed as per API 20 and mesh size > 550.0 TO 655.0 microns is designed as per API 30 and so on.

With the continuous development of innovation, the further development of technology, human found a new discovery, improved the previous existence. Likewise, the shale shaker screen has undergone modification, improvement and witnessing the new presentation. There are many types of shaker screens on the market.

Some types of shaker screen:

-Derrick shaker screen

There are two Derrick shaker screens

-Flat Screen (PWD)

This is the old Derrick shaker screen model. And pyramid shaking screen is cheaper.

-Pyramid shaker

This is an improved version of the flat screen. Has a higher drilling fluid handling capacity than the flat screen more effective.

-Hookstrip Soft Shaker screen

This is the early use of the vibrating screen. Has been surpassed by the newer models.

Hookstrip flat screen

The Hookstrip flat screen has a vibrating screen for easy sorting, screening and screening. It is usually used by the driller. Layer 2 to 3 layers of hooks and layered screens used in plastic enhancements enhance screen saver.

-Steel frame

This screen is commonly used in the industry. It is made of 2 to 3 layers of stainless steel, tightly tied to the frame, to make it strong. Rubber stoppers can be used to repair gaps or breaks.

This makes the screen cost-effective.

-Composite screen

The composite screen is an improved version of the steel frame. The vibrating screen is lighter and more durable and can withstand high temperatures.

Shale Shaker Screen is main spare parts for shale shaker. Shale Shaker Screens are easy to be broken during the shaker operation when drilling well.

Drilling fluids shale shaker is a kind of filterable mechanical separation equipment, compared with other mechanical solids control equipment, its unit cost is kinda of economic. And it is a highly efficient separation equipment which obtains solid removal amount. Drilling fluids shale shaker is made of screen body, machine rack and gearing. Accordingly, mechanical vibration will make solid phase which is bigger than screen hole and the adhesive attraction will screen the solid phase particles which is smaller than screen hole. But all mud can’t be processed in circulating process because of the limit of shale shaker mud permit.

Usually the material of drilling fluids shale shaker is stainless knitted. Usually this kind of screen uses mesh to express the specification. Mesh is the number of screen holes, for example, a square screen that has 12 holes is called 12-mesh screen. Screen with a special outfit screen holder will screen into flake tension type fixed on the screen frame. Screen body is fixed to the rack based on spiral spring, and rubber articles’ bumper adopts the bottom-fixed type.

The Parts of the Shale Shaker Screen Panel

Oil Rig Shaker Screen Frame-Much like a canvas for painting a screen has to be supported on a frame in order to do its job, this frame differs between manufacturers in both material and shape. Screen frames can be made from materials, such as, square steel tubing, flat steel sheets, plastic type composites or they can just be supported on the ends with strips of steel ( similar idea to a scroll ). These frames consist of a rectangular shaped outer perimeter which is divided into small individual inner panels. These smaller panels differ in shape from manufacturer to manufacturer and have been known to come in shapes such as square, hexagonal, rectangular and even triangular.

These differing panel shapes are used in an attempt to reduce the quantity of panels on each frame but still provide maximum rigidity and support for the mesh attached to them. The purpose of reducing these panels is to maximize usable screening area as the walls of each panel get in the way of the mesh and prevent it from being used, this is known as “blanking”. The non-blanked screening area of a shaker screen is widely used as a selling point, the more screen surface you have available to work, the more efficient your shaker becomes and therefore can handle a higher quantity of fluid.

Screen Mesh-Just like thread is woven together to create cloth, metal wire can be woven to create a metal cloth. Screen Mesh has evolved over many years of competitive screen manufacturing resulting in very thin yet strong cloth designed to maximize screen life and conductance as well as to provide a consistent cut point. To increase the conductance of a mesh screen you have to minimize the amount of material in the way, this is done by either reducing the wire diameter or weaving the cloth to produce rectangular openings. Rectangular openings increase the screens conductance while minimizing the effect on its cut point where as square openings provide a more consistent cut point but offer a lower conductance.

To maximize screen life most manufacturers build their screens with multiple layers of mesh over a very sturdy backing cloth to further protect the cloth against solids loading and wear. The multiple layers of mesh act as a de-blinding mechanism pushing near sized particles, which may get stuck in the openings, out of the mesh reducing blinding issues and keeping the screen surface available for use.

Binding Agent-The binding agent is the material used to bind the mesh to the screen frame, it is designed to maximize adhesion to both materials while being able to handle high heat, strong vibration, abrasive cuttings and corrosive drilling fluids.

Plastic composite screens tend not to use adhesives but rather heat the mesh and melt it into the screen frame to form a bond.

3D Screen Technology-One of the more recent advances in oilfield screen technology has brought us the “3D screen”, this technology is an innovative method for increasing the screening area of a shale shaker without the need to build larger machines. When seen from the side, these screens look like corrugated cardboard, having a flat bottom and wavelike shapes on top. These waves are designed to increase the surface area of the screen panel by building up instead of out, thereby maximizing the surface area of the screen without the need to build larger shaker screens and in turn larger, heavier and more expensive shakers.

Kosun solids control undertakes equipment selection, design and manufacturing according to material data and actual demands of users. We warmly welcome users to visit our Company for field investigation, technical exchange and long-term cooperation.

What’s the Solid Control System consist of?

Kosun as the professional solid control system manufacturer, we have our own understanding about this system.In Kosun’s words, solid control system is also called drilling fluids purification system, primarily applied for solids control and solid-fluid separation in drilling fluids so that the drilling mud might be recycled. Consisted of 3-7 module composite tanks and configured with 4 phases of purification equipment, it is fit for 2000-7000 meter oil drilling processes. The whole system is innovative with the bottoms of its purification tanks made to be conical and its edges equipped with mud agitating system to prevent solids from depositing.

What’s the  Solid Control System consist of?

solid control system

The first main equipment for solid control system should be the vacuum degasser,We could analytics from the function of vacuum degasser. Generally speaking, horizontal vacuum degasser will be used to separate the gas from the drilling solids. What’s the reason to do like that? Because we should do everything to prevent any dangerous elements in oil & gas drilling fields. That’s why we should put the vacuum degasser as the first role.

The second one should be mud cleaner. KOSUN MD Series Mud Cleaner is the second stage separation equipment for drilling fluids, which deals with the mud being treated by the first grade separation equipment. The barite will be recovered and cuttings which are bigger than barite will be removed. Then the barite in the underflow will flow into circulation tanks through the screens when the weighted mud passes while the particles that are bigger than mesh will be removed.

The third equipment, we think it should be shale shaker (with necessary steel frame shaker screen). Actually, after the drilling solids have been transported and fed into vacuum degasser and mud cleaner, the third step is going with shale shaker. Commonly, we still need to be transported the solids onto the shale shaker, or we could say onto the surface of shaker screen. The equipment of transporting we should use is centrifugal sand pump or screw pump; and we may use shear pump to cut the drilling solids into small one if they are in big size. With the different design of the shaker screen’s mesh, we could get the drilling solids separated in different sizes.

The fourth equipment should be the decanter centrifuge. KOSUN DC Series Decanter Centrifuge is used to separate suspended solids ≥2μm in diameter and treat the drilling mud and fluids. It is especially effective when used in oilfield service industry, industrial service industry and especially in environmentally sensitive areas. This type of centrifuge is high in recovery rate, effective in solids control and remarkable in the reduction of cost spent on drilling mud resupplying and management.

Of course, the whole equipment must be mounted on the top of drilling mud tank, which is a kind of basic equipment for both solid control system and drilling waste management (vertical cutting dryer is the core equipment for this system), but it is a kind of powerful equipment.

How to Properly Use Shale Shaker Screen?

 Shaker Screen

Shaker Screen consists of a frame that can either be of steel or plastic, into which mesh can be fitted. This mesh does the work of separating the mixture of solid and drilling fluid. A binding material is used to bind the mesh with the frame.

For maximum efficiency,  Shaker Screen must be used properly. Following points describe how to properly use it.
–    The cloth that is used for making the mesh must be of good quality. Also, if the layering of the mesh is increased, the efficiency of the screen will automatically increase and the fineness of the mesh will also increase.
–    Methods must be implemented to increase the life of the screen. For this the first method is to have a very strong screen so that the meshes are supported very firmly. The second method is to provide proper tensioning to the screen.
–    The screen must be protected from over tensioning or under tensioning.
–    When not in use, the screens must be properly removed from the machine, cleaned and stored properly. Extra care must be taken while storing the screen.
–    Also, when the screen in being installed, care must be taken that they are not mishandled. Mishandling of the screen, especially during installation may cause extra wear and tear.
–    The weight of the mixture that is being fed to the screen must be in accordance to the amount of weight that the screen can handle. Different types of screens are available for various sizes of the mixture.
–    The screens must be cleaned frequently and carefully. Care that must be taken during cleaning the screen is, the water that is being used is not of very high pressure or else it may cause the mesh to unbind from the frame.

KOSUN will supply better goods and services to customers continually.

 

Brandt Shaker Screen Replacement – Drilling Fluid Equipment

Brandt Shaker Screen

Brandt shaker screen is the key component in shale shaker equipment. They function as a sieve to block the solid drilling waste and let the precious drilling fluid to be carried to a separate channel for further treatment.

Shaker Screen is used in Shale Shakers as part of solid control system in drilling operations of various industries, such as oil and gas drilling, mining, coal cleaning, etc. They primarily serve the purpose of separating drilling cuttings from the drilling fluids.

Drilling fluid is a cocktail of number of chemicals that help in the drilling process. Drilling fluid is prepared in two variations – water based and oil based, and they are very costly to obtain. They serve as lubricant agent to keep the drilling waste management system efficiently functioning. They keep the drilling bit cool and clean to penetrate deeper into the borehole.  And because of these reasons, operators invest in technologies to lower their overall operational cost and also for the environmental purpose. Shale Shaker are one such equipment to achieve that goal.

Shaker Screen has two integral parts – a screen Panel and a screen Mesh. A screen panel will hold the mesh in place, to efficiently serve its purpose. It is much like a larger frame that holds smaller sections of the mesh with help of intersections. The frame itself comes in different material and shape. One key differentiator among them is the area of mesh between these intersection, that could be utilized for the screening. These intersections are known as “blanking”. The lower the blanking better the shaker screen’s performance.

The screen mesh could be understood as a piece of cloth woven with the wires to form fine rectangular openings. The screen mesh comes into variety in terms of its durability and conductance. Then there is a binding agent that joins the screen panel with the screen mesh.
The most modern development in shaker screen field is introduction 3D screen technology.

Brandt Shaker Screen

Shale shaker is a very important equipment that is used in the first stage separation of drilling liquids and the solid materials obtained from drilling oil, gas or water wells. This shale shaker consists of a shaker screen that does the separation process.

Brandt Shaker Screen comes in various types and different mesh sizes. Its two main types are the hook type and pretension type. Also the amount and the size of the solid that will get separated depends upon the size of the mesh.

Because of its importance, it is very important that the shaker screen is cleaned regularly. Cleaning it regularly will increase its efficiency and will delay the wear and tear of the mesh.
Various methods of cleaning the screen are;
1) Self Cleaning:
– This methodology involves the use of small folded or creased wires.
– These wires are arranged on a surface in such a way that small gaps are created resulting in a mesh like structure. This is usually supported using Support bars so that they are free to vibrate. These vibrations prevent the blocking or jamming of the mesh.
2) Water based cleaning:
– In this method a high pressure water pipe is used that cleans the screen by pouring water on it at a very high speed. This is a very traditional method that cleans the screen when less cleaning is required.
3) Screen cleaning machines:
– These machines are fully enclosed machines. The screen is placed inside this machine where a powerful water gun, releasing water at a very high pressure, is used that cleans the screen.
– The advantage of this machine is that it is fully automatic and no effort is needed at the workers part.
– Also this machine reduces the time required for cleaning a screen there by increasing the overall cost effectiveness.

Shale Shaker Screen Many Types | Kosun Manufacturer

Shale Shaker Screen

Shale Shaker Screen happens to be the most dynamic part of the shale shaker equipment, as this performs the most important part of separating the solid waste from fluid in a drilling process. At the same time it is the most vulnerable part of the equipment also because it constantly deals with solid particles and chemical rich fluid that makes it prone to wear and tear easily.

Shale shaker screen has also evolved over time in design and performance. Shale shaker is the primary part of a solid drilling waste management system .  The latest development in the field is the introduction of 3D screen technology.

The basis of differentiation among various types of shake shaker screen remains to be their conductance. The manufacturers apply their innovation in shapes and designs to improve it’s performance. A few common types of shale shaker screens out there are –
Flat Screen
A flat screen type is the most common and traditional type of the shaker screens that could be mounted to most of the shale shakers. A flat shaker screen is also very cost effective. This contains the steel panels that are bound together by steel plank.

Pyramid Screen
Pyramid screens are an improvised version of flat screens. A pyramid screen effectively increases the screening area without the need of changing the structure of the shaker. With help of more screening area the fluid quantity increases and results in better
production.

Metal Framed & Composite Framed Screen
Shaker Screens are usually metal framed and that standard is widely accepted in the industry. Composite frames are an extended version of the screen frames and since the introduction of composite frames, it has become quite popular among contractors due to their light weight and durability.

Hook Strip Screen
The hook strip screen comes in variations of sizes and designs and is used for straining and sieving etc. The mesh is secured with the help of clamping rails and the tension is applied with the help of woven wire cloth referred to as a hook strip.
