DC Machinery drilling fluid decanter centrifuge

The decanter centrifuge has become a major processing tool in a wide range of liquid/solid separation applications. There are lots companies have ability to manufacture types of decanter centrifuges.

One of the biggest advantages to having an oilfield decanter centrifuge is the size that it takes up. Compared to other solids control equipment, a centrifuge takes up less real estate. On many oilfields the site footprint is not large enough to support a wide range of solids control equipment. A centrifuge is highly effective and efficient so you can separate solids from drilling liquids even on small drilling sites.

Mud cleaners delivery to Singapore drilling contractor

Mud cleaner is the second stage equipment of solid control system. Last week, DC machinery shipped 2 sets mud cleaner to Singapore government drilling contractor. The number of the desander and desitler cones is customized to the drilling circulation system mud flow. And our shaker unit can easily fit in with the hyrocyclones

mud cleaner

The mud cleaner combination consists of two sets of hydro cyclones: a desander to eliminate particles of 120 – 60 μ, and a desilter which eliminates particles smaller than 60 to 20 μ. The combination of varying physical mud cleaning principles results in a high capacity mud cleaning combination with high a operational efficiency and minimum maintenance, repair and replacement costs.

mud cleaners

The shale shaker is often installed after the shale shakers where the sand trap drilling mud feeds into the desanders and desiters respectively, the underflow of hydrocyclones loads onto the dewatering screens for recycling the usefully drilling fluids back to the mud system. The drilled cuttings above the screens are therefore dried which lowers drilling cuttings disposal cost.

DC Machinery Mud Cleaner completes consist of everything you need to plumb up to and operate the equipment as it own stand alone unit. Just select the Mud Cleaner and
Shaker combination you need based off of the flow rate you need to process and what micron level you need to cut to.

ZYQ series Mud gas separator designed features

ZYQ series Mud gas separator(Poor Boy Degasser) is professional equipment to treat the gas invade mud. When the drilling mud result gas invade, the proportion of its weight and viscosity have a greater deviation not to meet the requirements of drilling. The serious situation is that would cause Chung well, and even blowout accident
occurred, if not to treat it timely.



Design Features
1.Large effective vessel capacity
2.Removal of dangerous H2S and other poisonous gas
3.Baffle plates in vessel
4.Customized specification
5.Backpressure manifold with flare ignition line
6.Effective U-tube or mud seal configuration
7.Skid-mounted design with lay down legs
8.Optional elevating type

For mud gas separator, the material is rather important. Harmful gas including H2S is corrosive and poisonous. So DC Machinery produces poor boy with Q345R (HIC) plate. Such degasser are resistant to H2S compatable for such corrosive gas.

Supply drilling fluid circulation system and centrifugal pumps

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 (i.e. mud pit).

solid control

The main components related to the circulating system are mud pumps, mud pits, mud mixing equipment and contaminant removal equipment . Solid control system mainly include, shale shaker, desander, desilter, decanter centrifuges and ect.



Besides above, DC Solid control also suppli all capacity feeding pump, include sand pump, slurry pump, water pump and ect.

We will always supply the drilling fluid system, the parts and the technology service to ensure the efficiency in the production of our customers. Our tenet is, making the advanced technology, ensuring the good quality, and offering the best service.

DCZCQ oifield vacuum degasser produced from DC Solid control

Vacuum degasser is very important for returning mud gravity, stabilizing mud viscosity and reducing drilling cost. Also, at the same time vacuum degasser can be used as a heavy-power agitator and supported applicable to all types of mud circulation purification system.



Vacuum Degasser is also called mud/Gas separator. Mud/gas separators (Degasser) is the first units of solids control equipment arranged to treat drilling mud. As such, they process all of the drilling mud from the flow line before the mud reaches the primary shale shakers. The units have no moving parts and rely on the density difference between the gas and the mud for removal. The process is simple, yet very effective for well drilling fluids processing system.

Unlike the traditional vacuum degasser, DCZCQ vacuum degasser is a self-contained unit, dc Vacuum Degasser is monitored by level sensor to protect over suction of the fluids. The gas-cut mud is drawn into the degasser by a vacuum created by a regenerative vacuum without needing centrifugal pump.

Besides above DC degasser can act as a big agitator for the drilling mud, which helps the treatment for desander and desilter.

A new generation of vertical cutting from DC Solid control

As a leading drilling waste management and solids control company, DC Solids control company developed the first generation vertical cuttings dryer in 2013. After three years testing and research, DC Solids control announced that the latest designed second generation vertical cuttings dryer has been successfully developed and tested for drilling waste management.

Unlike the first Generation and traditional Vertical cuttings dryer, DC Solids Control has improved the Vertical cuttings dryer with a patented scraper system inside the basket screen, and a high pressure air knife system is fitted to assist in continues cleaning of the screen for the vertical cuttings dryer while working.

vertical cutting dryer

This reduces the downtime for cleaning the vertical cuttings dryer screen. And this featured design cuttings dryer make it possible for water based drilling mud system cuttings drying which has significantly gives better drying performance than the linear motion shale shakers. The high torch completed Sun-Wheel Gear box unit ensures
the second generation vertical cuttings dryer to run more reliably than the gear driving system.

The VFD control system allows the vertical cuttings dryer to run at different G force and different differential speed to handle the drilling cuttings in proper conditions. The combined drilling cuttings picking up augers allow the drilling cuttings dryer to sit at a relatively lower profile and make it easier for the set up
of the feeding screw conveyor.

Hot sales hydrocyclone size units of DC Solid control

The specially designed drilling mud hydrocyclone units are primarily used for removal of sand-size and silt-size particles from returned drilling fluids. DC Machinery resistance polyurethane hydrocyclones are applied to the unit. The unit can be stonealone for use or assembled above our shale shaker through pre-designed connectors.  The number of desander and desilter cones is customizable according to the real conditions.

And the commonly used hydrocyclone size are 10″ and 4″. Following is the detail introduction of the two size hydrocyclones.


10″ Desander

Sand size solids removal (40 ~ 100 microns)
100% polyurethane hydrocyclone
500 gpm per cone at 75 feet of head
Flexible fast connection is available for user to assemble
Compact design, small footprint


4″ Desilter

Silt-sized solids removal (12 ~ 74 microns)
100% polyurethane hydrocyclone
80 gpm per cone at 75 feet of head
Variable size apex inserts
Available with and without a ramp in the feed inlet
Flexible fast connection is available for user to assemble
Compact design, small footprint

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.
