A customized drilling mud processing system is is ready for shipment at GN Solids Control Beijing factory. It mud cleaning system is composted of a mud cleaner, a mixing hopper, and a centrifugal pump for mud mixing and transfer.
The drilling mud cleaning and mixing system is designed and made by client’s request to suit his drilling mud situation. Normally, mud cleaner is equipped after a pre-seperation shale shaker. But in this mud cleaning system, the first separation equipment is mud cleaner.

Drilling Mud Cleaner

The reason why the client do not use shale shaker is that, they said the solids content in the mud is not much high. And mostly are fine solids. In this case, the drilling mud can be separated by mud cleaner directly. It is to save cost. As once the shale shaker is running, clients need to replace shaker screen periodically. It is a continue cost for operation. While delete the shale shaker, the system can meet client’s request. It can save the cost of shale shaker, and furthermore, the can reduce wearing spare parts shaker screen cost.

But if the solids content is high, or the particle side is big, which is over the hydracyclone separation point and its mud handing capacity, it is better to use a shale shaker before the mud cleaner. At one hand, the shale shaker can reduce the flow rate which feed to the mud cleaner. At another hand, after the shale shaker separation, the solids content will be reduced, and the big size particle are total removed based on the shaker screen API size and cut point. It can increase the hydraucyclone separation efficient, and also to avoid the fast wear out the hydraucyclones. 10 inch desander cone and 4 inch desilter cone are the most popular cyclone sizes used for drilling fluids separation system. Operator can choose the to use only desander cone or desilter cone, or both based on the mud condition and their budgetary. Desander and / or desilter cone quality depends on the handling capacity of the whole system.

Drilling Mud Centrifuge

Feeding pump for mud cleaner is centrifugal pump. The centrifugal feed pump is located on tank slope for compact design and for maximize the total tank usable volume.

After the mud recycling and mixing system, a drilling mud decanter centrifuge is used for fine solids separation. As there will be more and more fine and ultra fine solids after some circulation of the system. Decanter centrifuge will be used to reduce the mud weight.

Mud De-sanding Unit will save a lot in Piling Project

BY admin 10 February 2017 Drilling Fluids shale shaker, Drilling mud system, HDD machinery, mud recycling, shale shaker, solids control, Solids Control Equipments

Vertical rotating drilling rig is the normal machine used in piling project. During the drilling process, in order to protect the inner wall of the drilling hole and speed up the process, the operator always chooses to use drilling mud. Then here comes another problem how to reduce cost of the drilling mud thereby to reduce the cost of drilling. The solution is to use mud recycling system to make the drilling mud reusable.
The purpose of the mud recycling system is to remove the large size solid particles in the drilling mud by several separation machines. In regards to the mud recycling system for piling project, it could be a very compact design as separation process is not so complex as that for oil gas drilling. GN solids control is one of the most experienced separation solution providers who could provide the mud recycling system for almost all the industries will use it. GN already developed the standard mud recycling system especially for the piling project.

De-sanding Unit

Strictly speaking, the mud recycling system used in piling should be called de-sanding unit as the drilling depth is normally shallow and most of the solid particles are sand. A de-sanding unit would be enough for processing the separation to get the expected reusable drilling mud.
GN’s de-sanding unit is a compact structure 2 steps separation system. The main equipment in this de-sanding
unit is combined with a 2 layers shaker and cyclone manifold. The double layers shaker is used for coarse solids separation by the under layers and the upper layer screen is for drying the slurry discharged from the cyclone unit. The tank under the shaker unit is used to store the drilling mud. One centrifugal pump is installed in the system for transferring the mud to the cyclone unit for sand separation.
This de-sanding unit could be connected with extra mud tank for larger capacity mud storage. The operators can also equip a jet mixing unit to make an self-contained mud recycling system for other drilling project like HDD and water drilling.

GN Non Oil Drilling Mud Recycling System is Widely Used

The business of today’s GN has been divided mainly into 2 scopes, one is the normal drilling mud recycling, and the other is the waste management including the waste coming from petroleum related and other separation industries. This blog is mainly talking on the drilling mud recycling system that used in non oil drilling industry.
In oil drilling, the drilling depth and safety regulation request large drilling mud storage and more solids control equipment. Thus, the mud recycling system is always equipped with degasser unit and large volume mud tanks.

HDD Mud Recycling System

Comparing with the mud recycling for oil industry, the unit for non oil drilling is more compact and less equipment needed.

Trenchless/No Dig HDD project – The mud recycling system used in this type drilling is matching with a No dig rig. In some project for long distance pipeline and cables laying underground, it is inconvenient to dig an open groove on the ground as that will interrupt the normal traffic. The trenchless is an ideal choice. The mud recycling system for this project is always consisting of 3 stages separation as shale shaker unit, de-sanding and de-silting cyclone.
Piling is the main method to install the bridge supporting pillar. A de-sanding unit with a small tank would be enough to remove out the coarse solids from the drilling fluids. The de-sanding unit is a composition of de-sander cyclone and shaker unit that can separate out the solids with size of 40-70 microns. Piling does not request very clean mud; less equipment involved makes the recycling unit for piling is very compact.
GN also can manufacture the mud recycling system for tunneling project. For micron tunneling, GN has model available with capacity of 120m3/h, 240m3/h and 500m3/h. For large flow rate request, GN has the mud plant GNMS -3600M with treating capacity of 3600m3/H.

Tunneling Mud De-sanding Plant

Besides, GN’s mud recycling system can also be used in water well drilling, coal bed methane exploration, dredge slurry separation and the mining flushing waster cleaning process.

Most of the horizontal directional drilling mud system is not equipped with decanter centrifuge unit as by using the 3-phase separation system including shale shaker, de-sander and de-silter unit, it can work good enough for removing the solids from drilling fluids. Centrifuge is relative high cost, which is also a reason the drilling contractor doesn’t equip it in the mud system.

GN Centrifuge System

However, for some high request drilling condition, the driller may use the heavy mud for better drilling performance. Sometimes the drillers add the certain chemicals to make the drilling mud heavier so that the mud can better protect the wall of the drilling hole. If the driller went to drill another well, the heavy chemicals need to be separated, and then the centrifuge could be used to do this job. In some other conditions, after many times recycling of the drilling mud, there is much ultra fine solid particles that cannot be removed by the shaker and cyclone unit, and then the centrifuge unit is needed.
GN Solids Control has nearly 10 years in fabricating the drilling mud system for HDD projects. This type mud system need to be compact structure and easy for transportation. See the picture in this article, both the de-sander and de-silter unit are equipped with under flow shaker for drying the discharged solids. The shakers used are 2-layer screen design. The bottom layer screen is used as primary shaker and upper layer screen to dry the discharges out from the cyclone units. This design greatly reduces the footprint of the mud system. And all tank top surface equipment are pre-installed on a frame with same base dimension as storage tank. When transport the mud system, the shaker and decanter centrifuge units could be removed by lifting the frame for fast disassemble. With the frame, the equipment could be easily transported by flat bed trailer.
GN can provide both standard and customized HDD mud system for clients. Just send us your request, and then you will get a satisfying and cost effective solution.

One set 500GPM drilling mud recycling system was sent to Middle East for water well drilling. Besides the drilling mud recycling system for oil drilling, they also need drill water well for daily requirement for clean water. For the person living in Middle East, water is more important than oil. Sounds like a joke, but this is reality.
Water well is not so deep like the oil well, and the drilling cost is also very cheap comparing with oil drilling. However, both this 2 drilling processes need the drilling mud recycling system to speed up the drilling process and protect the drill bit. Water well drilling may not need the used drilling mud to be separated very clean as it is not requested strictly. Just like this 500GPM unit shipped to Middle East, it is a very compact
model, while it has all the necessary separation equipment.

water well drilling mud system

It has one unit shale shaker GNZS703DZ with 3 panel screens which could remove out the solids always larger than 300 microns. This model is with the mud feeder on top of the shaker deck so that this shaker could be much more compact. As the water well drilling is always not so deep, hence, the solids coming out with the drilling mud is always not so hard. In this 500GPM mud recycling system, the de-sander cone is not equipped, but directly the de-silter cone would be used to separate the solids size of around 20 microns.
This 500GPM water well drilling mud system is a standard GN model GNMS-500G with 2 unit centrifugal pumps. One of each is used as feeding pump for the de-silter cyclone, and the other one is used for mud mixing, the mud tank is divided into 2 compartments. It has enough space for clean mud storage.
Though this 500GPM mud system is for water well drilling, it can also be used in other drilling project like HDD. As the working principle is completely the same. The customer killed two birds with only one stone.
