cleaning system

3 sets GN fast removable mud recycling system for HDD rigs will be dispatched to the client this week. It is customized system for CPP rigs. CPP engineering team visit GN factory and check the system before dispatch and very satisfied. They are happy with the system quality and thanks very much for the continue technical supporting of GN Solids Control for the years. Till now, they have over 35 sets compact mud recycling systems from GN Solids Control. Most of the systems are for 500GPM capacity.

The 3 new systems are customized with 500gpm capacity also, but can up to as 1000GPM mud system capacity when needed.
The 500gpm ~ 1000 GPM mud recycling systems are composed of below equipment:
1) Mud tank 1 ea. The size of the tank is the same with 20ft standard container, and equipped with ISO blocks. Walkways and handrails are all foldable type design for fast movement. During inland shipment, the users no need to remove the walkways and handrails, they only need to take off the pin shaft and supporting beam of walkway, and fold up the walkway and handrails to the tank side wall.
2) Mud cleaner desander (model GNZS706E-2S) with double deck shale shaker. It is the combination of a double deck shale shaker and 2 each 10’’ desander cones. The bottom shaker deck can be used as solids control shale shaker for preseparation.
3) Mud desilter cleaner (model GNZS706E-8N) with a double deck shale shaker underneath. The bottom deck of the shaker will be used as solids control shale shaker.
The 1 ea desander mud cleaner and 1 ea desilter mud cleaner are mounted in a lifting frame, they can be moved as a compete part during shipment when needed.
4) Feeding pump for desander and desilter cones are mounted in the slope of the mud tank for a compact design.  
For other sizes of GN mud recycling system for HDD rigs, please you visit GN website or contact GN company for details.

HDD means horizontal directional drilling. Many people are wondering when HDD machine used? You see, you want to put pileline undergoud pipeline, but there is a huge river in the area. How did you do, to full up the river or change direct to pass it? No, it is huge work. With HDD machine, you can put pipes in a depth first, and then cross pipes under the river. Another condition like that, it requests to put some underground pipes for cable, for water, for natural gas, etc… in city area, but it is not possible to dig up the ground, there are buildings and constructed road on it. With HDD machine, things will be very easy.

80T HDD machine is a most common side drilling rig. The high pressure is between 1000 to 2000 liters. 350~500GPM mud system is used for this rig size.

For different customer and different rules for discharge, there are different standard mud system.

If your 80T machine is for HDD, we recommend you GN350~500 GPM mud system.  

Simplify proposal as below:

1) GNZJ705E-6N mud cleaner for 2 phase separation. 1 each

It is a double deck shale shaker, with 6 each 4inch desilter cone above the shaker.

2) Centrifugal pump: 5’’*4’’, 22kw, 2 each

3) Mud gun: 1 each

4) Mud tank dimention: 6058x2250x1600 (the same dimension with 20ft container)

5) Slurry pump feeding for shale shaker, 11kw, 1 each

6) Light system and electrical control system.

We offer TURN-KEY solution. You only need to plug-in with our power and then press START of the system.

China Petroleum Pipeline Bureau (CPP) is the biggest HDD contract in China. It is a government controlled company. CPP have drilling actives worldwide, in China and outside China.

 

TBM is Tunnel boring machine, it is similar to piling. It is widely used for municipal construction, like subway, tunnel, etc… There are high content coarse rock particles generated during the process. It does not have high standard for mud quantity. No need separate to very small size. It request big capacity for a rough separation, like 120m3/h or 240m3/h mud systm.

Mud plant for TBM Tunnel boring machine

It is compact mud system with double deck shale shaker, and desander hydra cyclone above the shale shaker to used as a combination of mud cleaner. 10’’ Desander cone quantity varies from 1 ~2 for different capacity (120 CBM or 240 CBM). TBM mud system use steel frame screen (e.g. 0.3mm, 0.5mm, etc…) and desander cone. Desilter normally is not used in TBM drilling mud system.

CBM (Coal Bed Methane) is more and more widely used. As natural gas as a clean energy type become more and more polular.

CBM (Coal Bed Methane) mud system is similar to HDD (Horizontal Directional Drilling). Compared with TBM and piling, it has a higher request on mud quality.

Mud cleaning system used for CBM drilling:

1) Per different capacity, Shale shaker is single deck or double deck, and utilize shaker screen 2 panels, 3 panels or 4 panels.

2) Desander cleaner

3) Desander cleaner

4) Mixing machine

3) Sany Heavy Industry (China)

Desanding plant for TBM and mud cleaning system for CBM us different. They are not changeable. Customer should specify the rig type before order. For any questions on compact mud system, you can contact GN group for solution.
