Shaker Screens Replacement of Kosun Manufacturer

Shaker Screens is a critical component in solids control equipment used in the 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 the 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 a drilling rig. As the drilling bit will cut through the rock underneath the 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 helps in keeping it cool and clean for further operations.

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 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 types of equipment are used, among them a shale shaker is the foremost.

A shale shaker with the help of  shaker screens helps separate 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 to 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 that could be really harmful to the environment and cause contamination of soil or groundwater. The drilling industry follows strict rules on drilling waste management for the sake of environmental impact.

In conclusion, a shale shaker’s main function is to filter the drilling waste with the help of effective shaker screens and as a result help in the 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.

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.

Drilling is widely used activity in oil and gas industry, to obtain deep seated fossil fuel to fulfill the fuel requirement across the globe, and that makes this industry quite enormous. The drilling operations are carried out on hard ground surface or on the ocean surface. In the entire drilling process, one of the main challenges is the handling of the drilling waste , it is called solid control system. The drilling waste mainly consists of drilling cuttings (solid) and drilling fluid (mud). Now the drill cuttings are nothing but the rock shavings and other hard particles that are extracted during drilling, the drilling fluid is a mixture of different chemicals and oil or water. The drilling fluid is quite expensive substance and is added to the drilling process to help drilling waste equipments lubricated and cool, besides other things.

API being one of the largest trading group of US in drilling industry, has set up certain industry standards to test the quality of shaker screens, that are respected worldwide. Based on these tests, they have labeled different shaker screens sizes that approved by ISO, and encourage the manufacturers to use those labels on the product to enable the end user for a fair comparison before purchase.

While quality of different shaker screens cannot alone assure its performance, as the actual performance, in terms of conductance and life, will depend on a variety of aspects. To name a few – Handling of shaker screen, installation and replacement, appropriate tensioning, deck rubbers, storage and cleaning, volume of mud and solids, etc.

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

Shaker Screens – Drilling Fluid Equipment of Kosun

Shaker Screens

Shaker Screens are 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.

A 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.

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 equipment 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 Screens have 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.

Let us take you through the shaker screen installation process one step at a time. The very first step in the process will be to shut down the equipment completely, unplug the power and wait for the equipment to come to a stationary position. Step two will be to clean the equipment that will hold the screen in place, in case you replacing the older ones, or want to just clean and refit the same screen, make sure the screen and the equipment is in clean condition and also look out for any wear and tear of screws or straps that holds to keeps the shaker screens in place. After this the third and final step is to mount the shaker screen panel onto the shaker deck and slid it toward the equipment to fit into the slot. Make sure that the draw bolts are unlocked beforehand and ready to engage with the screen panel’s feed end. Fasten all the screws and nuts back into the place.

The size and shape of shaker screen will vary from manufacturer to manufacturer and so will the fashion in which they will be mounted. Few popular examples are, Hook Strap Screen, Wedge Blocked Screen, Steel framed screen or composite frame screen. Each will essentially be different only in the way they are fastened to the  shale shaker deck.
