About the Drilling Cuttings Solidification Unit (shorted as “DCSU”) that manufactured by GN Solids Control, in this article we will mainly introduce its working principle.


Before showing its working principle, firstly let us know its main application and treatment material.

05043_副本Usually, the DCSU is used as the 2nd-step treatment measure with the drilling waste, mainly it is used for treating the drilling cuttings and realize cuttings’ solidification.

During the Drilling Waste Management, the 1st-step is to use the High-G shaker and Centrifuge (for water-based waste); Vertical Cuttings Dryer and Centrifuge (for oil-based waste). After the 1st-step’s treatment, the liquid-content (water, oil) in the drilling cuttings will be decreased effectively.


In order to reduce the cuttings’ hazard to the environment, now the DCSU will be used, here below is its working principle:


  • Drilling Waste Collection hopper collects all the drilling cuttings, then they will be moved to the mixing chamber by the screw conveyor under the hopper. The capacity is based on pre-set.
  • Through the screw conveyor under the cement storage box, the cement is also sent to the mixing chamber based on pre-set capacity;
  • The same for the absorber, which is sent to the mixing chamber by the screw conveyor;
  • On the mixing chamber, there are 2 inlets: 1is for feeding water, the other is for feeding the chemicals;
  • There are high-shear mixer in the mixing chamber, which can mix all the materials sent into the chamber. After the cuttings and other waste are mixed sufficiently with the cement and chemicals, solidification happens and finally they are discharged out from the mixing chamber;


The solidified drilling cuttings can be used as the construction material or the hazard to the environment can be effectively reduced even though the solidified cuttings are disposed directly.


Finally, sincerely welcome to contact us for any need about the equipments or system, GN can make the customized solution for you.

Mud cleaning system is two main parts, the storage mud tank on below and many machines serve as purify the drilling fluid, which get rid of the solid debris in drilling fluid. The mud tanks which store drilling fluid are divided into circulation tanks and store tanks. Circulation tanks as a part of the filter cycle, there are shale shaker, vacuum degasser, deserter, and desander and decanter centrifuge on the top of tank.

The 1st level of purification
the drilling mud pumped away from the rig and flow-down in the shale shaker. The allocation drilling fluid enter into the bottom of the drilling well under the foundation of the drilling pump and carry drilling debris return the ground, through the elevated tubes enter into the shale shaker, the larger solid debris in drilling fluid are filtered through screen

Desander with GNZS752 Series Mini Shale Shaker

The2nd level of purification
When drilling fluid have debris contain gas, The use of vacuum degasser remove the gas which in the drilling fluid and can recover the density of drilling fluid, calm the drilling fluid viscosity.

The 3rd level of purification
the drilling fluid is disposed by two levels, mud purification enters into the desander.  Through the desander feed into the liquid pump, the harmful sold phase which the diameter is above 40-60um is separated in desander.

The 4th level of purification
the drilling fluid is disposed by the three level purification enter into the desilter through the desilter feed into the liquid pump, the harmful sold phase which the diameter is above 15-40um is separated in desilter.

The 5th level of purification
The drilling is disposed by the four level purification enter into the decanter centrifuge through the centrifugal feed liquid pump, the small harmful sold phase particles are separated in decanter centrifugal.

Usually, all five purification is all working at the same time. If it works one equipment or several equipments, the parameters of the drilling fluid can all meet the work requirements; it can work in one equipment or in several equipments. After the purification, drilling fluid can re-use in the drilling cycle

Screw Pump
As what showed in below picture, GN could manufacture and provide the Screw Pump from 4Kw to 22Kw, the pump flow is from 10m³/h to 90m³/h.

The GNG series Screw Pump is the ideal pump for feeding the decanter centrifuge.

As we know, the Decanter Centrifuge is usually used for separating the very fine solid particles in the drilling fluid, the drilling fluid will not be sheared and agitated by using the Screw Pump to feed the Decanter Centrifuge, so the separation effect could be better, which is related with the special structure and working principle.

Screw Pump

1.Working Principle of GNG series Screw Pump
The Screw Pump is mainly composed of 2 parts: the screw shaft (rotor) and shaft bushing (stator).
The motor drives the “rotor” to rotate, the drilling fluid flows along with the “rotor”. The rotation speed is low and the capacity of each helical cavity is same, which ensure the low flow speed and the fluid pressure is constant and there is no vortex and agitation with the drilling fluid. That is also why the Screw Pump is the ideal pump for feeding the Decanter Centrifuge.

2. Features & Advantages of GNG series Screw Pump
1). The Shaft Bushing (stator) is made of elastomeric material, so it has the particular advantage than other pumps to transfer the drilling fluids with high viscosity or hard suspended particles included.
2). As the wearing parts, the Screw Shaft (rotor) and “Shaft Bushing” is convenient for replacement;
3). Less accessories, compact structure, small volume, easy maintenance;
4). The Screw Pump could be driven by using the coupler, variable speed motor, V-belt, gearbox, etc.
5). There are different Explosion Standards with the motors & electrical control panel, such as EXdⅡBt4, IECEX, ATEX that could meet different customer options;

One fixed 500GPM drilling mud recycling where possible system was sent to Center East for water very well drilling. Besides the drilling mud recycling system for essential oil drilling, they also need tool water well for day-to-day requirement for clean water. For your person living in Middle Distance, water is more important as compared to oil. Sounds like a job, although that is reality.
Water nicely is not so deep much like the oil well, and the drilling cost is also very cheap looking at with oil drilling. But both this 2 drilling processes need the going mud recycling system to be able to speed up the drilling procedure and protect the punch bit. Water well going may not need the used drilling mud to be separated extremely clean as it is not required strictly. Just like this 500GPM unit shipped to Midst East, it is a very stream-lined model, while it has all of the necessary separation equipment.GN drilling mud system

They have one unit shale shaker GNZS703DZ with 3 panel screens which could remove out solids always larger than 600 microns. This model is by using the mud feeder along with the shaker deck so this shaker could be considerably more compact. As the water very well drilling is always not so deeply, hence, the solids developing the drilling mud is obviously not so hard. In this 500GPM mud recycling system, typically the de-sander cone is not loaded, but directly the de-silter cone would be used to individual the solids size of all-around 20 microns.
This 500GPM water well drilling mud system is a standard GN model GNMS-500G with 3 unit centrifugal pumps. One among each is used as giving pump for the de-silter cyclone, and the other one is useful for mud mixing, the mud tank is divided into a couple of compartments. It has enough space regarding clean mud storage.
Even though this 500GPM mud system is for water well drilling , it can also be used in other drilling project like HDD. Since the working principle is completely the identical. The customer killed two chickens with only one stone.

While Oil rig perform the drilling into the earth core, it needs to break soil and rocks apart. Some layers often is harder than other so drilling operation will use additive to strength the drill bit to break the layer. The additive that use combine the rock sometimes will cause the harm of environment .
Underground of earth is not totally solid and sometime it contains the layer of water like underground river. When water mix with the drilling process, it contains various of heavy metal ion and anion. Such content in water will change the stability of the drilling fluid that affect the performance of the fluid. When water is in the drilling fluid increasing, the various additive will be added into the drilling fluid. The mixture of drilling fluid and additive is harmful to the environment if reach to surface and not properly treated.
