The angles at left and right sides of screen basket are synchronously adjusted, which is more convenient and stable, and can avoid the common mud deviation. The rolling pulley structure is more labor-saving than the sliding type.

Separation Principle of Drilling Fluids Decanter Centrifuge

The mud separation process between solid phase and liquid phase is completed in the roller. 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 desander centrifugal force by solid phase particles of liquid ring and the ratio of its own gravity called decanter centrifuge separation factors, the larger desander centrifuge separation factor can separat finer particles from the mud. Currently drilling desander centrifuge can be divided into three types according to the size of the separation factors:

a.Low speed decanter centrifuge：it 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 decanter centrifuge is mainly used for recycling barite.

b.Medium-speed decanter centrifuge: the 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.

c.High-speed decanter centrifuge: its 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.

Mostly due to this, oil-based mud is required.

Decanter centrifuge is really one of the most useful machines, because it has found wide application in many industries. The commonnest industries include oil well drilling, biological wastewater treatment, food processing, chemical slurry, etc. It is used to extract particles from liquids.

The first stage is traditional centrifuging, returning the underflow to the active mud system. Rather than discarding the overflow, it is routed to the second centrifuge running at a higher speed, where the low-gravity solids supposedly are discarded and the “clean” liquid is returned to the mud.

Solids control is so indispensable in drilling that we can’t work in drilling without it. As one of the professional manufacturers in China solids control, KOSUN provides all the solids control equipment, such as shale shaker, decanter centrifuge, vacuum degasser, etc. KOSUN can also manufacture a whole solids control system for oil& gas drilling as the requirements of the customers.

KOSUN Solids Control Equipment Are on Sale in Domestic and Abroad

Shale shakers are the primary solids separation tool on a rig. After returning to the surface of the well the used drilling fluid flows directly to the shale shakers where it begins to be processed. Once processed by the shale shakers the drilling fluid is deposited into the mud tanks where other solid control equipment begin to remove the finer solids from it. The solids removed by the shale shaker are discharged out of the discharge port into a separate holding tank where they await further treatment or disposal.

Mud loggers usually go out and check the shakers for shaker samples that have circulated from bottom. They separate the shaker from the drilling fluid and take it into an onsite lab where they dry out the samples and label them according to depth. They then look at the samples and analyse what kind of rock they have at a certain depth. This helps determines what depth that type of rock was encountered.

As usual, due to metal "hard in hard" cooperate relationship easy to lead to the shale shaker wear and tear on parts when it in the process of running, for example, the shale shaker main shaft bearing wear and failure. After go wrong the above problems, the traditional enterprise solution is machined after repair welding or brush plating to repair, but both of the ways have some disadvantages: repair welding of high temperature thermal stress can not completely eliminate, neither repair welding thermal stress effect, repair the thickness is not restricted, and at the same time the product of metal materials do not have rolled back, and it also can absorb the impact of shaker equipment, avoid the possibility of wear and tear, and greatly prolong the service life of equipment components, save a lot of downtime for the enterprises, creating huge economic value.

How is the desilter separate silts from drilling muds?

In general, desilter is the third stage solid control equipment to treat the drilling fluids. That is a centrifugal device for removing very fine particles, or silt, from drilling fluids to keep the amount of solids in the fluid at the lowest possible point. Usually, the lower the solids content of mud, the faster is the rate of penetration.

A desilter is used to separate silts from drilling muds. The cut point can be as low as 4. As muds are being used in drilling operations, they are contaminated with silts. In order to use again these muds, it is necessary to separate silts and also to recycle muds to dispose them at the end of work duty.

Desilter is designed by the theory of particle sedimentation. The separation medium-drilling fluid produces some pressure and speed when it passes the centrifugal pump, and flows into the hydrocyclone along the wall, the bigger solid particles along the wall of hydrocyclone sink spirally under the centrifugal force and gravity, and to be discharged from the bottom flow hole and fall on the under micromeshsieve for separation. The other mediums rise along the spiral of hydrocyclone, flow into the fourth class separation equipment-centrifuge for a further cleaning treatment from the overflow hole.

But with more than 20 years’ industrial experiences and technology development, KOSUN now expand its scale to a middle size and improved its technology to a high level. The gap between products from KOSUN and those international big brands is very small now.

Why mix and agitate drilling mud with KOSUN Systems?

KOSUN is a professional oilfield drilling mud mixing agitator supplier and manufacturer in China oil drilling mud solids control industry. Mud agitator is a very important equipment in the drilling fluids process.

What is the mud agitator are consist?

KOSUN MA series mud agitator is a kind of drilling fluids solids control equipment, which is mainly used to agitate and mix the drilling mud to prevent solids particles from depositing in the circulating tank and to stabilize the performance of drilling fluids. Drilling mud agitator is composed of explosion-proof motor, speed reducer, motor base and blade. The connection between motor and speed reducer, speeder reducer and impeller shaft is achieved by steel coupling, the impeller is welded by four blades.

How is the drilling Mud agitator work?

The KOSUN mud agitator produces powerful, sequentially timed pulsed of compressed air to generate large bubbles at the bottom of the mud holding tank. The rising air bubbles create immediate vertical circulation of the drilling mud and stirs the entire mud tank from the bottom up. Accumulator plates are attached to the mud tank bottom and introduce the compress air bubble. The burst of compressed air from underneath the plate scours the drilling mud tank bottom and efficiently lifts solids and heavier liquids up into the tank. This “bottom-up” vertical mixing process keeps solids is suspension, ensures uniform mud consistency and level in the tank.

This type of drilling mud mixing process is faster and more energy efficient than top entry mixer or jet mud mixer. Regardless of the holding tank geometry or hull design, the KOSUN drilling mud mixer can be custom designed to fit any size drilling mud mixer to help improve the overall efficiency of the drilling site.

KOSUN is capable of providing customers with series products, such as oil & gas drilling fluid solids control equipment, decanter centrifuge, drilling waste management equipment and drilling security equipment.

KOSUN Solids Control Equipment Are the Best Choice for the Drilling Industry

Besides drilling mud solids control, KOSUN also offers the drilling waste management equipment. Last year, KOSUN provided 2 units of cutting dryer and decanter centrifuge package to Russia for drilling waste cuttings treatment. Now the machines are still running well, that is a successful project for KOSUN.

The mud/gas separator captures and separates large volume of free gas within the drilling fluids. If there is a "kick" situation, this vessel separates the mud and the gas by allowing it to flow over baffle plates. The gas then is forced to flow through a line and vent it to a flare. A "kick" situation happens when the annular hydrostatic pressure in a drilling well temporarily (and usually relatively suddenly) falls below that of the formation, or pore, pressure in a permeable section downhole, and before control of the situation is lost.

The drilling fluids flows into the jet pump with certain pressure, in the jet pump, fluids spouts out from jet nozzle first, then flows into shear pipe through mixing chamber. Materials will be added from hopper to mixing hopper, and move into shear pipe with the flow. During this process, they are dispersed and mixed. The mixture will enter mud tank after flowing out of the shear pipe.

Solids control is so indispensable in drilling that we can’t work in drilling without it. As one of the professionals in solids control, KOSUN provides all the solids control equipment, such as shale shaker, decanter centrifuge, vacuum degasser, etc. Apart from being specialized in designing & manufacturing of jet mud mixer, KOSUN can also manufacture a whole solids control system for oil & gas drilling based on the requirements of the customers.

Characteristic of KOSUN Drilling Vacuum Degasser

Degasser is a device used in drilling to remove gasses from drilling fluid which could otherwise form bubbles. It is necessary to install a drilling fluid vacuum degasser for their removal from the drilling fluids since the invading gases may impact mud properties, cause safety risks and affect the lifespan of some equipment.

Vacuum type is the most common form of degasser. It can be horizontal, vertical or round vessel. A vacuum action is created to pull in the gas cut mud. When the liquid enters the mud tank, it will flow and be distributed to a layer of internal baffle plates designed for the mud to flow in thin laminar film and is exposed to a vacuum that forces the gas to escape and break out of the mud. The vacuum pump moves the escaping gas from the vessel discharging it to the rig's flare or environmental control system.

Vacuum degasser is a special-purpose oil drilling fluids solids control equipment and a new type one for the drilling fluids system. Drilling fluids degasser can get rid of various gases invading drilling quickly. Drilling mud vacuum degasser is very important for returning mud gravity, stabilizing mud viscosity and reducing drilling cost. Also, at the same time oilfield vacuum degassing machine can be used as a heavy-power agitator and supported applicable to all types of drilling mud purification system. The drilling vacuum degassing unit design of the structure is scientific and rational. So we are able to achieve an effective gas-liquid separation, filter out impurities and to ensure that the exhaust pipe is always smooth.

Drilling fluids mud gas separator is the primary degassing equipment for disposing drilling fluids. Compared with vacuum degasser, the major difference is the mud gas separator is mainly used for eliminating the big bubbles whose diameter is larger than 3mm in drilling fluids. In addition, mud/gas separator is mainly by gravity impact action to realize the separation, and yet the vacuum degasser adopts the theory of vacuum, centrifugation.

The handling capacity of vacuum degasser is less than the mud gas separator, but can eliminate gas more thoroughly. Generally the drilling fluids disposed by mud/gas separator still contains minute bubbles, after through shale shaker, and enter into the vacuum degasser to dispose.

Mud cleaner for the drilling mud solid control system of several major parts

Compared with the independent desander and desilter, mud cleaner has much higher working efficiency. Same as the shale shaker in function, the equipment is designed rationally with compact structure, small volume and powerful performance.

As one of the important equipment for solid/liquid separation system, the drilling mud cleaner, also called desander and desilter assembly, mainly consists of three parts including desander, desilter and the underflow screen. It can achieve separation of two stage with the hydrocyclones mounted over the shale shaker.

Mud cleaner is a combination of desanders and/or desilters mounted over a shaker with a fine mesh screen. A mud is fed to the inlet of the hydrocyclone (desander and/or desilter) to separate particles and the underflow passes to the fine screen mesh where particles larger than barite are discarded and thrown away. In most drilling operations, a mud cleaner is installed in its mud system. It is usually located in a mud tank in the same location with the desilter.

The purpose of the mud cleaner is to remove drilled solids larger than barite. Solids between 74-105μm can be removed by the mud cleaner before the viscosity builds up. Mud cleaner can effectively control weighted drilling fluids solid content. It can also prevent sticking caused by differential pressure.

The hydrocyclone of the desander and desilter is made of 100% PU and its number is set according to the needs of customers. With the hydrocyclone for desilter of clamp type and stainless steel ball valve available, the product can be maintained easily. KOSUN Mud Cleaner can dry solids so it can be matched with our own advanced shale shaker. Meanwhile, the wedged type shaker screen allows people to change fast screen.

Structure and Principle of KOSUN Decender for Oilfield Drilling Equipment

In drilling fluids treatment system, the desander is the two-level solids control equipment used. As one of the indispensable and important devices for stabilizing and regulating those technical indicators of the drilling fluids, the drilling mud desander has also been extensively used in the purification of the drilling fluids.

The desander is primarily and widely applied in the petroleum industry, the oil and gas drilling, the exploration industry, the trench-less engineering, the geotechnical engineering, mining, metallurgy, coal as well as the hydroelectric industry.

As the combination of the hydrocyclone desander and the vibrating screen, the drilling mud desander is the three-level solids control equipment used in the solids control system of the drilling fluids. It is primarily made up of the vibrating screen, the distribution manifold as well as the hydrocyclones. The drilling mud desander is mainly used to remove the harmful solid phase with the granularity of more than 45μm so as to ensure the good properties of the drilling fluids.

The desander system is made up of the screening system, the adjusting and supporting system, the aqueduct, the foundation, the pressure gauge as well as the desander hydrocyclones. The desander is designed on the basis of particle setting principle. The separated medium-drilling liquid enters along the inner wall of clone spirally, depending on the pressure and speed produced by centrifugal pump. Under the function of centrifugal force and gravity, the larger particles are sunk along the inner wall of clone spirally and drained from bottom outlet to be separated in shale shaker with smaller mesh. Other mediums are ascending along clone spirally to enter the second separation device from overflow outlet for further purification.

KOSUN has been the major supplier of solids control products in the field of China’s oil & gas drilling equipment, the earliest and only one centrifuge manufacturer in five provinces in Northwest China, and the producer of the first-generation high-frequency drilling fluid shale shaker in China.
