Marketing used of Desander and desilter hydrociclones

Desander and desilter hydrociclones are device to separate particles from drilling fluid, which is sorted by shale shaker in the first phase of solids control system. Usually they are located after shale shakers.

Desanders make separations between 40 and 100 microns and offer the flexibility ­­of mounting either one, two, or three 10” desander cones over a cone underflow pan. DCCSQ desanders are also available in vertical or inclined manifold stand-alone models, or for inclined mounting on Derrick shakers.

desander

Desilters are designed to remove silt-sized (20 to 74 microns) solids from drilling fluids. DCCNQ’s round desilters are simple to operate and easy to maintain. DC’S polyurethane hydrocyclone offers a high volume 4” cone, while providing contractors an economical replacement for less efficient older equipment.

desilter

The standalone desander/desilter hydrocyclone unit can be assembled above linear motion shale shaker to recycle the useful drilling fluids from hydrocyclone underflow screening by fine mesh screens. Mud cleaner which combines desander, desilter and dewatering shale shaker in one unit is often used in nowadays drilling applications.

The mud cleaner is designed to remove the drill cuttings

Mud cleaner is consisted of shale shaker,desander and desilter for oil&gas well drilling fluids treatment system. More importantly,mud cleaner works more effectively,especially in cleaning functions compared with separated desander and desilter.Sometimes,it can be used as a shale shaker.

cleaners

Mud cleaners are used to remove drill cuttings from drilling fluid, known as mud. The mud is a non-Newtonian fluid of variable viscosity that serves several purposes in drilling operations. Mud is used to drive the down-hole motor, cool the drilling bit, carry the drill cutting to the surface for disposal, and maintain hydrostatic balance in the well.

mud cleaner

The mud cleaner is designed to remove the drill cuttings while allowing the weighted fillers of the mud, commonly barite, to stay suspended in the mud. The cuttings, consisting of solids greater than 74 to 105 micrometers, are filtered out in the staged process of the mud cleaner.

According to the customers’requirements, DC SOLID CONTROL company can design the mud cleaner which can meet almost all needs.

Function of drilling fluid and drilling fluid equipment

The drilling fluid circulating system is like a close loop electric circuit through which drilling fluid (i.e. mud) can travel from surface to all the way down hole and back to its initial point.

solid control system

The main component of the drilling fluid circulation system include shale shaker, desander, desilter, vacuum degasser, decanter centrifuge, mud tank, agitator, centrifugal pump. mud hoppers and ect. The drilling fluid circulation system also called solid control equipment or solid control system.

The function of the Drilling fluid and equipment maintenance cost can decrease greatly when proper solids control practices are utilized. From a fluid control stand point it would be desirable in most cases to remove all drilled solids. Although this is possible, it would be cost prohibitive.

The goal of a solids control system is to achieve the balance between mechanical solids separation and dilution that will result in drill solids being maintained at an acceptable level with a minimum of cost.

 

 

Application Industries of the poorboy degasser/mud gas separator

Mud gas separator is commonly poor boy degasser. It captures and separates large volume of free gas within the drilling mud. 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.

Mud gas separator located at downstream of the choke manifold is one of the important well control equipment that you need to focus. It separates gas out of the mud after the gas comes out of hole.

mud gas separator

DCZYQ series mud gas separator combined with the Flare Ignition Device can be used together to ensure the drilling process smoothly. Our separator is divided into normal pressure separator and pressure auto-control separator according to the pressure.

The Mud Gas Separator is mainly used to remove the enormous free gas from drilling fluids, including poisonous gases like H2S. Currently it is widely used in Drilling Waste Management, oil & gas drilling, trenchless HDD, city bored piling, Coal Bed Gas Solids Control System, Oil Mud Seperation, mining, Oil Sludge Dewatering Systems, Water Drilling, environment protection etc.

Desander for treatment of waste water industry

Desanders are used to remove suspended solids from liquid process streams. One of the primary applications is to improve the quality of waste water. Treatment of waste water normally involves multiple process steps to remove the impurities and ensure that the final effluent discharge is compliant to regulatory specifications.

desander

A desander has an entry port near the top on the side of the vessel, a hydrocyclone central component, and two discharge points (one on the top of the vessel and one on the bottom). The hydrocyclone is oriented so that the wide opening is at the top and the narrow opening at the bottom.

Mining equipment of mud cleaner use introduction

Mud cleaners are two-stage solids control equipment that are composed of several hydrocyclones mounted over a vibrating screen, known as a shale shaker. Mud cleaners are used to remove solids from drilling fluid and act as 2nd and 3rd phase solids control equipment.

The mud cleaner is designed to remove the drill cuttings while allowing the weighted fillers of the mud, commonly barite, to stay suspended in the mud. The cuttings, consisting of solids greater than 74 to 105 micrometers, are filtered out in the staged process of the mud cleaner.

cleaner

The first-pass solids control devices of the mud cleaner are the hydrocyclones which are mounted over the vibrating screen of the shale shaker. Several hydrocyclones are used to increase the flow rate of the mud. There is also a combination of varying sized hydrocyclones. Smaller cones, typically 4″ in diameter known as desilters, remove finer silt sized solids, while the larger cones typically 10″ in diameter known as desanders removed the coarser sand sized particles.

mud cleaners

The vibrating screen of the shaker is sized for the specific drilling operation. Lighter mud with lower solids content would use a finer screen while drilling fluid with higher solids content, known as weighted mud, would use a slightly coarser screen in order to ensure that the weighted fillers are not filtered out of the mud.

 

3 Sets ZJ40 mud system shipped to Russian

DC Machinery is a specialist provider of separation and filtration services to various markets ranging from the Oil & Gas and Petrochemical Industries to the provision of services to agricultural industries. DC Machinery is proud to offer an unrivalled fleet of decanter centrifuges to client requirements.

solid control system

Yesterday, DC Machinery shipped 3Sets ZJ40 mud system for Russian clients. The mud system mainly include 6 sets shale shakers, 3 sets mud cleaners, 3 sets decanter centrifuges, 3 sets vacuum degasser, mud agitator and centrifugal pumps.

oilfield equipment

Solid control equipment is used in drilling rig to separate the solids in the drilling fluid that are crushed by the drill bits and carried out of the well surface. Normally solids control system is consist of mud tank, shale shaker, vacuum degasser , desander, desilter, centrifuge ect.

DC Machinery strive to provide to its clients quality solid control equipment which provides better performance with minimum error.

Our Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (mud). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system.oilfield Decanting Centrifuge are able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, high G-forces separate fine solids from liquid.

If you have request with the decanter centrifuges, please contact me freely.
