How to choose the right shale shaker screen for the shale shaker?

For drilling fluid shale shaker, the shale shaker screens is reproductive structure principally device, it principally will take away the solids that are larger than the screen mesh openings. The drilling fluid with little solids would flow through the screen meshes, and right down to the mud tank for the any purification. Whereas the massive solids or the cuttings would stay the screen, and be vibrated and flow to the discharge finish of the shaker basket. Thus it's extremely necessary to settle on a correct screen in step with the solids diameter, mud gravity, consistence & density etc. As improper screen choice will cause loss of pricey drilling fluids, premature pump failures, overloading of different solids removal instrumentality like a centrifuge, shrunken instrumentality life, reduced rate of penetration and high issues within the well bore.

Shale shaker screens contain steel frame kind, pyramid kind, hook strip flat kind and stuff kind. Made with totally different raw materials and structures, the merchandise will support instrumentality to implement screening the solids with different sizes. The steel frame product principally consists of steel frame and a pair of to three layers of chrome steel meshes that integrate with steel frame tightly.

It has rather high strength and fits for screening the solids with massive weight. The pyramid product has relatively massive effective space and may be used additional flexibly. The specially designed hook strip flat product has long lifetime and high strength for very cheap, coarse wire screen mesh with little mesh range is integrated with the steel liner tightly. Additionally, KOSUN provides the shale shaker screen manufactured from composite materials. The dimension of this sort of product are often tailor-made in step with customers' necessities.

Shale shaker screen surface: sometimes, larger contact space screen can have higher treating capability, the additional screen area you have got suggests that additional volume that you simply will clean. Therefore, the vavy screen is healthier than flat screen; the larger space flat screen is healthier than little space flat screen.

Shale shaker screen selection: mesh size of screens is measured by the quantity of holes per sq in on the screen. totally different mesh sizes management the dimensions of the cuttings that you simply wish to get rid of. a similar mesh size won't add all drilling conditions. Sizes can vary looking on the dimensions of the cuttings and also the style of formations you're improvement.

KOSUN shale shaker screens are built to fulfill the precise models of "Derrick" instrumentality company shale shakers and may be put in directly on the shale shakers. At a similar time, KOSUN shale shaker screens have another feature that it adopts the wavy mesh on the frame to increase the screen space and improve the potency of method.

KOSUN LS584-D Hi-g dryer was gotten high praise from customers both home and abroad

Hi-G dryer is popular used for water based mud drilling cuttings treatment. After Hi-G dryer, high speed centrifuge will be followed for further treating. After treated by centrifuge, solids parts can be used for construction; liquid part can be further treatment by flocculent unit. Hi-G dryer is also can be used for oil based mud drilling cuttings treatment; vice versa, vertical cuttings dryer can also be used for water based mud drilling cuttings treatment. Based on this, KOSUN design it’s vertical centrifuge which can be used for both WBM and OBM drilling cuttings treatment.

It mud be noted that until the advent of KOSUN Hi G technology, the traditional method for control of OOC was install a cuttings wash/cleaning system. This was not only an expensive solution. But in some cases a very inefficient one, which sometimes reported higher figures than that being discarded from the shaker. As it is, the Drying Shaker requires minimal supervision. Together with its low operation costs and significant savings in fluid, it is an attractive alternative to any cuttings cleaning system. It can also be utilized well with high cost “pseudo” mud and/or “closed loop” systems.

Actually, High–G Dryer shares the same construction with shale shaker except its base height. The base of High-G Dryer is bigger than shale shaker. The difference between the shaker screen and Hi-G Dryer focuses their processing materials shale shaker processes the drilling mud and the High-G dryer deals with discharged drilling waste separated by solids control equipment. The following description will focus on the basic construction and spare parts of the Hi-G Dryer. It consists of shaker base, shaker frame, electric panel, shaker basket, shaker feeders, electric motors as well as shaker screens. When the shaker starts, under the driver of the motors, the vibration beam vibrates in certain rate and the beam then brings the shale frame vibration, which finally generates the whole shaker moving.

Application and Function of Three Different Rotate Speed Decanting Centrifuge

The purpose of the decanter centrifuge as applied to a weighted water-base drilling mud is to control viscosity. This is accomplished by concentrating the colloidal-size and clay-size solids fraction into the effluent (liquid) steam and disposing of this phase. The economic justification of using the centrifuge on this type of system is the simultaneous return of weight material. Using a centrifuge on weighted water-based muds eliminates the expense of throwing away (jetting) whole mud to control viscosity. Water dilution and excess waste volume are minimized.

Drilling decanter centrifuge separation principle is to use high-speed rotating roller driven into the mud in the high speed rotating drum, mud was dumped into the wall to form a liquid circle, solid phased particles of liquid ring get greater than its own gravity for undreds or even thousands of times the effect of centrifugal force, will overcome the resistance of the slurry viscosity to the roller on the inner wall of rapid subsidence formed solid layer, liquid forming liquid layer.

The high-speed decanter centrifuge separation factor is about 1200 ~ 2100, the separation point is 2 ~ 5 μ m, used to remove the harmful solid phase, control the mud viscosity, high-speed centrifuge discharge tank, liquid back into the circulatory system, at present our company in Mongolia drilling crew have high-speed centrifuge. The medium-speed decanter centrifuge separation factor of about 800, 5 ~ 7 μm, used to remove harmful solid phase of mud, control mud weight and viscosity, this is the drilling crew most used centrifuge resently. The low speed decanter centrifuge also called "Barite Recovery of Decanter Centrifuge", the separation factors is 500 ~ 700,for low density of solid phase, the separation point is 6 ~ 10μm. For high density solid phase, the separation point for 4~ 7 μm, the decanting centrifuge is mainly used for recycling barite.

A well known fact, drilling mud is the blood of oil drilling system, and it is very precious. The drilling mud solids control system can effectively separate the large drilling cuttings, barite and other large solid particles contained in the drilling mud returned to the ground from well. The treated drilling mud can be used repeatedly. The role of drilling mud solids control is to treat and recycle the drilling mud returned to the ground from well with solids control system or some solids control equipment, so as to reduce the drilling cost and protect environment.

KOSUN New Series Vertical Cuttings Dryer VC-2000 and Hi-G dryer can Drop the OCC to the Ideal Condition

Domestic zero discharge of drilling waste projects have skyrocketed since this year. KOSUN’s complete set of zero discharge drilling waste equipment is servicing successfully at CNPN Sulige gas field in Inner Mongolia.

Hi-G drye used to treat drilling waste drilling fluid processing system

Hi-G Dryer is also called Hi-G shaker as it is one kind of shale shaker which is as drilling mud solids control equipment. But Hi-G dryer is used to treat drilling waste in drilling fluid processing system. KOSUN Hi-G shaker recovers drill fluids cuttings from water-based and oil-based drilling fluids, can make the proportion of the liquid phase in the drilling to below 10%, can significantly reduce the cost of the waste discharge, and is particularly effective in the oil base mud cuttings.

It mud be noted that until the advent of KOSUN Hi G technology, the traditional method for control of OOC was install a cuttings wash/cleaning system. This was not only an expensive solution. But in some cases a very inefficient one, which sometimes reported higher figures than that being discarded from the shaker. As it is, the Drying Shaker requires minimal supervision. Together with its low operation costs and significant savings in fluid, it is an attractive alternative to any cuttings cleaning system. It can also be utilized well with high cost “pseudo” mud and/or “closed loop” systems.

With advanced KOSUN Hi-G technology, the Hi-G dryer shaker is efficient in recovering more oil based drilling fluids and the Oil On Cuttings (OOC) figures is significantly reduced. Another benefit is the elimination of whole mud losses from the traditional shale shaker. So with the use of Hi-G dryer shaker in the down stream of mud system, it can allows the shakers to run at their maximum capacity without the concern of the mud loss of the mud system. This is why the Middle East drilling contractor cone to us for the Hi G dryer for their existing mud system.
