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.

Rock Shaker Screen of Kosun Properly Use

Rock Shaker Screen

Rock shaker screen is the most critical component of shale shaker, as it plays an important role in separating the solid from fluid.

As it goes with any project operations, many a times the disaster will take place because of very basic things were overlooked or not taken care of. So prevention is better than the cure.

Following this philosophy, let us outline for you a few tips that could make you shaker screen last longer than you imagined:

  1. If the rock shaker screen let the large solid pieces pass through the screen, chances are that they will end up chocking the whole equipment and making your project operation to halt in no time. So make sure that you select the most optimum screen size.
  2. Timely preventive supervision of any shaker screens will go a long way in preventing any lasting damage to the equipment itself. The moment any wear and tear is spotted in the screen, even any blockage, consider taking it off and either clean it thoroughly before replacing or go for a new one altogether if the screen is not in good condition or reusable.
  3. Do not use sticks or brushes while cleaning the rock shaker screen, also make sure that you don’t end up using extra high pressure water guns to clear the screen holes, as it might be harmful for finer meshes.
  4. Mishandling may also cause damage to shaker screen during Storage. As storage of shaker screens is often times the most overlooked aspect. The screens storage in a way that prevents them from friction or jerks that might cause them to be torn away.
  5. The overall functioning of the equipment is also an important aspect, make sure that the deck rubbers are properly installed and not worn out. Also look at the condition of shaker basket.
  6. Always go for API conformed shale shaker screens only as to ensure the quality of your screen.

Shaker Screen—API Standardizes Criteria for Solids Separation

Shaker Screens

Shaker Screens are the wear part of shale shaker, mainly classified into soft sieve screen, sieve plate type screen,and frame plate type screen.

The American Petroleum Institute is a trade association in the oil and natural gas industry in US. API works in collaboration with number of stake holders in the industry for the betterment of the industry.

It also conducts research and help in standardizing the industrial practices. One such guideline related to drilling industry was the standardization of criteria for solids separation. It mainly attributes to the size of shaker screens across the industry that determines the quality of fluid.

The purpose of this standardization was to simplify the screen selection process and provide the users with the screens that will make the solid separation process more efficient.
The API first came up with a Recommended Practice of drilling fluid processing system evaluation (RP 13C & E). Which was also approved by ISO 13501. This RP 13 C broadly covers the tests that describe the openings on the screen of a shale shaker screen in comparison of known standards. It should be considered that this test only describes the openings in the shaker screen but doesn’t talk about its performance.

Conformity to API standards by a manufacturer by providing the information on the labels will help the users determine their choice in best manner. A buyer will use his discretion as to which screen to use to get best conductance or increased life and so on and so forth.

Based on the standardized labeling of shale shaker  screens the buyers are likely to make a more informed decision as to what is likely to work for their needs without leaving it guess-work.
Now as it happens with any change process, not all companies might embrace the system and continue to resist, while others do label the screens with the new standards. It is the end users prerogative to ask the manufacturer to provide the test related data for the screen that they intend to purchase.

How to Install Shaker Screen for Shale Shaker?

Shaker Screen

Shale screen and Shale shaker are critical in the drilling process. Despite this, the shaker screens are delicate and prone to damage by drilling solids which occasionally break them. Having equipment that meets the industry standards and maintaining it well is inescapable.

What use is there in having a good equipment that you cannot install? Due to the crucial role they play in the solid control process, understanding how to install the shaker screen is critical.

Perhaps when you first purchased, the screen was already installed in the equipment. However, because the screen is fragile and gets damaged in the course of working, it requires occasional replacement and re-installation. The steps outlined below have been incorporated with general observances that equipment users are familiar with. They will guide you about how to install a shaker screen.
i.    As soon as it is damaged shut down the equipment, close the feeder and provide tag.
ii.    Use your hands or appropriate tools to uninstall the screen.
iii.    Clean the screens in the drilling mud using water.
iv.    Transfer drilling solids from the shale shaker by using the centrifugal sand pump and the shear pump to cut the drilling solids into smaller sizes to ease transportation.
v.    Extract the screen from the equipment.
vi.    Put the screen carefully on the table. Tighten the screen carefully using screws. For multiple-layered screens go, through the process again for each of the layers of screen.
vii.    Bolt the screen on the side with the locating bar with the cuttings outfall on the outside and plug it into the generator trailer.

Your shaker screen is now installed and you are ready to resume work. Remember that much as it is imperative for the user to know how to install the screen, choosing the screen that meets industry standards is as paramount.

Shaker Screens for Sale of Rectangular Heavy Duty (RHD)

Shaker Screens

Shaker screens come in variety of sizes and shapes based upon shale shaker’s make and model. A Rectangular Heavy Duty Shaker Screen is mainly used for handling heavy solid drilling cuttings taken out during oil field drilling projects.

Drilling as such is widely used not only in oil and gas industry but in mining and coal cleaning industries also. Wherever the project demands handling heavy duty drilling waste management system , rectangular heavy duty shaker screens are deployed for use.

The main purpose of using shale shaker equipment is to separate out the drilling fluid from drilling solids i.e. drilling cuttings.
A Rectangular Heavy Duty Shaker screen uses two layers of finely knitted mesh material and one layer of a coarse mesh to enable the handling of the heavy duty solid waste to provide it better durability and better conductance. There had been number of incidents where during the solid control system process, while shale shaker was deployed to separate drilling cuttings from drilling fluid, some thicker parts of solid would get stuck in the circulation and make their way through multiple layers of mesh of the shaker screen and over time burst the shaker screen’s mesh cloth. To prevent such incidents, rectangular heavy duty shaker screens came into existence.

RHD shaker screens follow proprietary multi layered technology, that enhances the overall permissibility of drilling fluid through the screen with much less resistance, which naturally enhances the performance of shale shaker equipment.

The shaker screens in RHD line are available in different variations, based on the particulate size they allow to permit through and these are standardized by the America Petroleum Institute through their labeling practice. API has labeled different shaker screens based on the holes size distribution measured with the help of light.
As the technology advances, the drilling industry is all set to go through much more modernized with start to finish automation.

Derrick Shaker Screens Replacement of Kosun Manufacturer

Derrick Shaker Screens

Derrick Shaker Screens is the key component in solids control equipment used in drilling industry. Drilling operations use a borehole technology to penetrate deep beneath the surface to reach the fossil fuel, in this pursuit the mud-loggers first need to do a sampling to ascertain the depth and quality of rock they are penetrating.

In oil field digging, let’s suppose in an off-shore site, this drilling will be done with the help of drilling rig. As the drilling bit will cut through the rock underneath ocean floor, it will need some lubricant to keep it going, a drilling fluid is used for that purpose.

A drilling fluid is a rich mixture of different chemicals, either oil based or water based, this is commonly known as “drilling mud”. This drilling mud is very expensive to create, and it doesn’t only keep the equipment lubricated but also help in keeping it cool and clean for further operations.

Derrick Shaker Screens
Derrick Shaker Screens

The drilling bit will carry with itself drilling cuttings, essentially the rock shavings, mixed with drilling mud. The mud-loggers will extract these shavings from the drilling bit for their further analysis.

As explained earlier in the article, the drilling fluid is quite expensive so it is imperative for the operators to restore the drilling fluid from the drilling waste . For this purpose various solid control equipments are used, among them a shale shaker is the foremost.

A shale shaker with the help of derrick shaker screens helps in separating the drilling cuttings from drilling fluid, and the separated drilling fluid is channeled to a separate container for further processing and treatment. The dried solid, i.e. drilling cuttings are conveyed to a separate container for further treatment and disposal.

One very important factor in the solid control system is its contribution for environmental balance. If a solid control system is not efficient enough, it is likely that the drill cuttings will still carry some amount of drilling fluid that contains chemicals which could be really harmful for the environment and cause contamination of soil or ground water. The drilling industry follows strict rules on drilling waste management  for the sake of environmental impact.

In conclusion, shale shaker’s main function is to filter the drilling waste with the help of an effective derrick shaker screens and as a result help in economy of overall drilling operations and environmental prevention.

Any machinery will give its best performance if maintained properly, so a preventive measure is a prerequisite if an operator wants to ensure the long life of the machinery. While routine services will take place as part of your preventive maintenance, there is something that operators themselves will be able to take care of and be rewarded with even better results. A simple way is to keep the machinery clean.

In solid control equipment, shaker screen performs that key job of eliminating the solids through the screen. So it is imperative that they are prone to damage if not kept properly clean and that will naturally increase the overall project cost.

Here are some ways to keep the shaker screen clean and safe:
•    If the shaker has been idle for some time, it is important that the shaker screen be cleaned before the use. To clean the shale shaker screen, the best way is to use water gun or water hose.
•    Usage of wire brush will actually damage the mesh, so stay clear of brushes in your cleaning process.
•    The shaker screen constantly sieves the waste material and likely to get clogged with waste material and as a result the screen holes will be blinded and hamper the process if filtration. To clean the blinded screen holes, use the water hose from back side. You could consider removing the larger particles manually, but never with a brush or stick, as the mesh of the screen is prone to be torn in the process if you use any of these.
•    Make sure that the screens are not left with the drilling waste i.e. drill cuttings and mud to be dried while in the screen. This will invariably lead to a pre-mature failure of the equipment.
•    Never allow any worn out rubbers to be used in the equipment, this directly lowers the performance of the equipment and damages the shaker screen.
•    Do not allow any other material to be placed over the shaker screens, either in function or in storage.
With these basic cleaning procedures, you could ensure a longer life for the shaker screen.
