Shale Shaker, Desander Close Relation

Shale Shaker

Shale shaker form the first stage barrier through which the drilling fluid or the mud passes. It is basically shale meaning clay, mud or silt, that has some specific structure which has been untouched since its deposition in ground; which is here separated. . The waste is processed first in the shale shaker before transferring it to the other equipment.

It is used to separate solids with diameter above 75µm. Different components of shale shaker are hopper, feeder, screen basket, vibrator and basket angling mechanism and vibrator. They are believed to be most vital in solid control system as their performance direct has impact on the successive equipment and also relates to the quality of processed fluids.

Desander is a devices along with desilter form pair of hydrocyclones that differentiate sand and silt from the drilling fluid in borehole or downhole. Desander is added below the mud taker following by shale shaker and degasser.

A desander is typically positioned next-to-last in the arrangement of solids control equipment, with a desander centrifuge as the subsequent processing unit.  A drilling mud is added in its direction with an angle which is roughly at 90 degrees to it.

As the drilling mud is moved downwards in this cone shaped equipment solid particles are segregated from liquids ones by centrifugal force acting on these. This separated solid particles are allowed to continue move downward until is discarded from the hydrocyclones.

Desander are set to eliminate abrasive solids found in the drilling mud, which surpass the processing of H-I G Dryer Shaker. Desanders usually separate soild with diameter 45~74μm, and 15~44μm.

Different size of desanders and desilter are available which function similarly. They determine the size of particles the device removes from the mud system. Alike shale shaker desanders have no moving parts.

Shale Shaker of High Efficiency from Kosun Manufacturer

Shale Shaker

Shale shaker  is the first grade of solids control equipment in drilling purification system.

Shale shaker is mainly used in geographical engineering for mining of coal or other diesel products.

Increase shaker screening area- As per screening practices, decrease drilling mud amount in unit shaker screen is favorable to improve screening effect. When filled upto 80% to its capacity it performs as much as it could.

So make sure that the shaker screen is big enough to conduct screening drilling mud which always think 2:1 rate for the length to width of the screen is the best design. Thus improving shaker screen will facilitate better working of it.

Size of shaker screens matters too! When a bigger size shaker screen is used in shale shaker it not only increases the vibration strength and amplitude but also improves the hitting force and shearing force reacted by shale shaker screen to drilling mud and decreasing adhesive force between solid particles. Meanwhile, this measure is good at avoiding block of the screen to some extent, realizing drilling mud shearing and separation.

Basket angling mechanism-proper angling control the drilling mud flowing speed. Generally, big angle is faster than that of small angle. Although this practice is with big volume of shale shaker, it really does low efficiency. So, according to experience, it’s fine to keep cutting fluids speed <0.6m/S and 15 degrees for the screen.

Adding many layers screens to shale shaker- different particles are resent with different sizes thus to eliminate these multi-layer screen it can be used.  Setting several layers of screen with bigger mesh form low to upper screens help to improve the shaking screen efficiency.

Proper cleansing and maintenance of it- If cleaned by brushes or sticks it can lead to damage of the screen. It is must to use proper cleansing solutions . Never use water with an oil or synthetic based mud. For maintenance of the shaker ensure the shaker components are in good order; rubber supports, tensioning mounts etc.

Shale Shaker – Functions of Solids Control Equipment

Shale Shaker for Sale

Shale shaker 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.

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 shaker screen 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 handling 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 shaker screen and as a result help in economy of overall drilling operations and environmental prevention.

For enhanced efficiency and durability monitor and maintain your machine by
•    Storing the equipment in their boxes or according to manufacturer’s instructions.
•    Inspecting the machine to ensure it is properly mounted with the bolts properly oriented, the tension right and the screens properly aligned to the frame.
•    Inspecting all parts for tears and rips or wear and tear.
•    Replacing all worn parts bolts and deck and crown rubbers immediately for continued efficiency.
•    Do not walk on screens or allow staff to step on them. They can be damaged.
•    Avoid dropping tools on the screens.
•    Wash the screens thoroughly at the end of work every day to clean off mud and sticky substances.
•    Inspect the shaker screens at reasonable intervals for tears and holes. This will curb against letting mud accumulate and begin to weigh heavy against the equipment leaving it prone to heavy build-up of solids returned from the active mud tank.New
•    Inspecting and controlling mud weight will enhance screen life.

Poor handling of machines could reduce their life span and leading to machine failure. Inspection and maintenance of the drilling fluid shale shaker is a must for every end user of the shale shaker. It entails proper operation, installation, storage, monitoring and maintenance of the equipment.

As a separation equipment, the shale shaker separates harmful solids which are discharged into a separate holding tank while drilling mud is directed through the shaker screen . The role played by the shaker cannot be belittled. Shale shaker are important because
•    They separate drilling mud from unwanted solids
•    Discharge solids so they do not contaminate the drilling fluid
•    Remove harmful solid particles from the drilling mud
•    Provide rock samples for mud loggers to and analyze in order to determine the depth of penetration of the rock.

The shale shaker is composed of
•    The Hopper which is also known as the base. This serves as a platform for the shaker and feeder.
•    Feeder which is a collection pan for underflow
•    Screen basket also known as screen bed, a significant part of the equipment which transfers the shaker’s vibrating intensity and regulates its vibrating motion.
•    The basket angling mechanism has the capability to adjust its angle to allow different flow rates in order to optimize the use of the shaker bed.
•    The vibrator is a motion equipment which vibrates to facilitate the transfer and regulation of vibrating motion by the shaker bed.
