Plugging of the lower apex of mud cleaner hydrocyclones indicates that very large solids frequently bypass the shale shaker screens. Solids large enough to plug a 4-inch cone indicate the presence of a wide range of other solids. Even when linear motion shale shakers are operating properly mud cleaners remove a significant quantity of drilled .
Hydrocyclone is also called cyclone separator Hydrocyclone include hydrocyclone desander 10inch cone and hydrocyclone desilter 4inch cone which is used to separate sand and silt from the drilling fluid.A hydrocyclone has two exits on the axis the smaller on the bottom underflow or reject and larger at the top overflow or accept. The underflow is generally the denser or thicker .
Mar 02 2019 Bottom screens are the screen cloth on bottom shakers of hydrocyclone separator and mud cleaner. The screen types vary since the shakers design are different. Bottom screens types. There are different designs on bottom shaker for desander desilter and mud cleaner. Such as the mini bottom shaker with screen sized 1600x600mm with hook for .
Mud cleaners combine a hydrocyclone system with a shale shaker to help remove the fine drilled solids from the drilling fluid. Together they have the capability to process the entire drilling-fluid circulation volume and remove drilled solids from weighted mud systems retaining expensive barite and liquids and economically reducing hole problems associated with excessive drilled solids.
Desanders Figure 1.16 desilters Figure 1.17 and the combination of them called mud cleaners Figure 1.18 are hydrocyclone-type equipment. If operated properly hydrocyclones can perform the finest cut of any primary separation equipment operating on the full-flow circulating rate of an unweighted mud
Drilling mud Cleaners for drilling fluids solids control Drillingmud cleaner is also called Desander and Desilter assemblywhich is the combination of desanderdesilter and an underflow screen.Namelymud cleaners consists of a two-stage separation process using a combination of hydrocyclones mounted over a shale shaker to operate as a single unit.
Mud cleaner is a combination of desander and desilter and mounted over a shale shaker with a fine mesh screenampperiod A mud is fed to the inlet of hydrocyclone to separate particles and the underflow passes to the fine mesh where in particles larger than barite are discarded and thrown awayampperiod It is the second and third phase cleaning equipment for a whole solids control systemampperiod
Mud cleaners are normally positioned in the same location as desilters in a drilling fluid system. Frequently the desilters or hydrocyclones are used in the unweighted portion of a borehole by diverting the underflow away from the mud tanks. When a weighting agent barite or hematite is added to the system screens are placed on the mud .
Aug 19 2021 Drilling mud process hydrocyclone separators. Drilling mud process is the system to treat drilling fluids with cuttings. There are different equipment from shale shaker to hydrocyclone to centrifuge. For hydrocyclones theoretically the separation point is 15-74microns.

API Standard Second Phase Oilfield Solids Control Desander. Drilling Mud Decanter Centrifuge. Forth Phase SS304 Oilfield Drilling Mud Decanter .
The standalone desanderdesilter 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 cleaning system has the function of mud recycling and mud mixing of drilling mud. The mud system is engineer designed to clean recycle and mixing drilling mud in one mud tank package. The flow capacity is 500gpm with shaker operating at 40 mesh screens and mud density 1.2gcm . It removes undesired drilled cuttings down to 12 .
DC supplies Solid Control Equipment shale shaker screen desanders oil gas Mud Gas Separator Jet Mud Mixer. We focuse on the production and sales of mud cleaning equipment of petroleum drilling.
The Derrick round and inline desilters are designed to remove silt-sized 20 to 74 microns solids from drilling fluids. Derricks round desilters are simple to operate and easy to maintain. Optional shutoff valves on each round desilter cone inlet permit individual cone removal and inspection without interrupting operation of the desilter.
Apr 25 2018 Figure 1. polyurethane hydrocyclone. Hydrocyclone is core part of mud cleaner desilter desander. Hydrocyclones are a cost-effective method of removing many of the fine solids missed by the shaker in unweighted muds. Hydrocyclones separate solids from fluid by using centrifugal force to cause solids to be settled from the fluid. There are no moving parts.
A hydrocyclone is device that removes large cutting from the whole mud cleaning system. The desander should be located next of the shale shakers and degassers but before the desilters or mud cleaners. A volume of mud is pumped into the wide top section of the hydrocylone at an angle roughly tangent to its girth.
Mud cleaners combine a hydrocyclone system with a shale shaker to help remove the fine drilled solids from the drilling fluid. Together they have the capability to process the entire drilling-fluid circulation volume and remove drilled solids from weighted mud systems retaining expensive barite and liquids
In Elgins patented multi-functional mud cleaners the collection troughs can then be directed to the top deck or bottom deck depending on the application and desired level of solid-liquid separation. Hydrocyclones
Mud Cleaner. Desander amp Desilter amp Shale Shaker 3 in one unit mud cleaner for compact footprint. Polyurethane Material hydrocyclone for long life. Removable hydrocyclone assembly from mud cleaner skid for adjust to be a shale shaker. Patent electric shaker deck angle adjustable while working mechanical deck angle adjustment for backup application.
Nov 17 2016 Hydrocyclones are arranged with the unit of larger cone size upstream of the smaller unit. A separate tank is needed for each size unit. Generally a desander and a desilter manifold are available as part of the rig equipment. Hydrocyclones should process all drilling fluid entering their suction compartments independently of the drilling-fluid circulation rate. Continue reading
