The Work Principle of Decanter Centrifuge

The work principle of decanter centrifuge:Centrifuges, like shale shakers and hydrocyclones, are solids control equipment, It achieves the separation goal by dividing the fluid into highdensity and lowdensity streams to separate one from the other. The processing is achieved by accelerated sedimentation. As the drilling fluid passing through a rapidly rotating bowl, centrifugal force moves the heavier particles to the bowl wall, where they are scraped toward the underflow discharge ports by a concentric auger, also called a scroll or conveyor, which rotates at a slightly slower rate than the bowl. The separation of the heavier particles divides the processed fluid into two streams: the heavy phase, also called the underflow or cake; and the lighter phase, which is called the overflow, light slurry or centrate. The heavy phase will be discarded while the lighter one will be returned to the mud tank to be further treated. The removal of these solids in order to control rheology and filter cake quality is the primary reason for centrifuging weighted drilling fluids. When the finest solids are not removed, the only alternative means of reducing their concentration is dilution, always an expensive process.

Before hydrocyclones (desanders and desilters) and decanter centrifuge became available for drilling applications, shale shakers and dilution were the only means of solids control of drilling fluids. Consequently, solids too fine to be separated by the shaker screens in use could be controlled only by dilution which was a costly procedure that generated large quantities of excess drilling fluid. Decanter centrifuge was designed to remove the fine cut and at the same time reduce the drilling cost.

To meet the requirements of the development of modern drilling engineering, KOSUN developed and equipped with the explosionproof variable frequency control system which could adjust separation factor and drum rotational speed.By this new technology,make the centrifuge to adapt property changing of mud duringthe operation process,that make the treatment more effective and perfect.

Common Troubleshooting of Decanter Centrifuge

Solids control equipment in one of the indispensable mud sand pump equipment used in the process,Desander Hydrocyclone will encounter some of the problems of how we want to troubleshoot it?( Decanter Centrifuge Troubleshooting)

If worn, then Desander Hydrocyclone may be the following two questions:

The first packing (packing) seal leakage serious, packing heavy wear, surface wear sleeve.

Remedy: Remove the packing (packing), with a 90 ° bend thin wire inserted into the cartridge mechanical seals, Oilfield Drilling Mud Decanter Centrifuge is bushings moving wall, if the check of Oilfield Drilling Mud Decanter Centrifuge is to be too deep for-sleeve trench filler cap too tight will lead to severe wear fillers.

Second, DWM Solids Control of polyurethane seals wear serious cause leakage.

Remedy: Replace polyurethane seal (Normally, when the sand pump is running 3-6 months, Drilling Mud Cleaner should be replaced at once polyurethane seals and seal sleeve).

There must be an electrical engineer specializing in operation and maintenance. At present, only a few well-drilling operations abroad with the type of high-speed centrifuge, high performance requirements for drilling special wells, Drilling Mud Cleaner recommended speed centrifuges and centrifuge series of domestic high-speed process, the medium-speed centrifuge drilling into the post-processing of high-speed centrifuge for liquid storage, treatment by high-speed centrifuges, Drilling Fluids Desander used repeatedly into the circulatory system. Drilling Fluids Desander at this time to get a better purification of positive significance to improve the follow-up equipment of DWM Solids Control (drilling sand pump, drilling, downhole equipment, etc.) of the life-saving mud material consumption, improve ROP and other aspects in Dwm control.

Kosun solids control undertakes equipment selection, design and manufacturing according to material data and actual demands of users. We warmly welcome users to visit our Company for field investigation, technical exchange and long-term cooperation.

The Component of the Solid Control System

Solid control system is also called drilling fluids purification system, primarily applied for solids control and solid-fluid separation in drilling fluids so that the drilling mud might be recycled. Consisted of 3-7 module composite tanks and configured with 4 phases of purification equipment, it is fit for 2000-7000 meter oil drilling processes. The whole system is innovative with the bottoms of its purification tanks made to be conical and its edges equipped with mud agitating system to prevent solids from depositing. Besides, its tanks and bins may be comparted or united depending on the demands of drilling processes. Each of them is connected to another via pipe network in which the valves at the bottom of suction pipes are flexible while being opened, but can turn to be a good seal when closed.

The Component of the  Solid Control System:

Solid control system

The first main equipment for solid control system should be the vacuum degasser,We could analytics from the function of vacuum degasser. Generally speaking, horizontal vacuum degasser will be used to separate the gas from the drilling solids. What’s the reason to do like that? Because we should do everything to prevent any dangerous elements in oil & gas drilling fields. That’s why we should put the vacuum degasser as the first role.

The second one should be mud cleaner. KOSUN MD Series Mud Cleaner is the second stage separation equipment for drilling fluids, which deals with the mud being treated by the first grade separation equipment. The barite will be recovered and cuttings which are bigger than barite will be removed. Then the barite in the underflow will flow into circulation tanks through the screens when the weighted mud passes while the particles that are bigger than mesh will be removed.

The third equipment, we think it should be shale shaker (with necessary steel frame shaker screen). Actually, after the drilling solids have been transported and fed into vacuum degasser and mud cleaner, the third step is going with shale shaker. Commonly, we still need to be transported the solids onto the shale shaker, or we could say onto the surface of shaker screen. The equipment of transporting we should use is centrifugal sand pump or screw pump; and we may use shear pump to cut the drilling solids into small one if they are in big size. With the different design of the shaker screen’s mesh, we could get the drilling solids separated in different sizes.

The fourth equipment should be the decanter centrifuge. KOSUN DC Series Decanter Centrifuge is used to separate suspended solids ≥2μm in diameter and treat the drilling mud and fluids. It is especially effective when used in oilfield service industry, industrial service industry and especially in environmentally sensitive areas. This type of centrifuge is high in recovery rate, effective in solids control and remarkable in the reduction of cost spent on drilling mud resupplying and management. It is a very sophisticated dynamic balancing machine, able to operate stably with the whirling speed ranging from 0 to 3900 and generate centrifugal force of 3000G. In solid control system, decanter centrifuge has been popularly used, which is also the popular one for drilling waste management. In this step, we could not only get the result of separating, but also we could separate the oil from the drilling solids, even if the oil is just a little part.

Of course, the whole equipment must be mounted on the top of drilling mud tank, which is a kind of basic equipment for both solid control system and drilling waste management (vertical cutting dryer is the core equipment for this system), but it is a kind of powerful equipment.
