HDD

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.

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

2) SCHRAMM (America)

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.

Features of GNZS594 4-panel high G force drying shaker

GNZS594 is a high quality 4 panel high G force drying shaker for drilling waste management system. The drying shaker with adjustable high G force up to 8.0G. It is suitable for difference job site application, from mud solids control to drilling waste management.

Furthermore, shaker screen of GNZS594 high G force drying shaker is interchangeable with Swaco Mongoose shaker. It can minimize customer’s storage cost. The customer is easy to source replacement shaker screen locally. They can storage for screen for their own use as well as distribute to other customers.

In which system GNZS594 –panel drying shaker can be used

1) Water based mud drilling cuttings treatment. It is used as a dryer to drying the OBM cuttings. The fluids phase will be further treated by decanter centrifuge with high speed.

2) In some cases, GNZS594 –panel drying shaker can also be used to treat oil based drilling cuttings, as an alternative of vertical cuttings dryer. But it cannot separate as dryer as vertical cuttings dryer.

3) When reduce the G force (normally around 6.0 G ~ 7.0 G )and change the feeding type, it can be used as a normal mud solids control shale shaker at mud cleaning system.  

GN Solids Control is world famous manufacturer for mud recycling system for HDD, CBM, piling, underground instruction, trenchless, dredge slurry separation, etc…
GN Solids Control also offers customized solution per customer’s condition. A customer request 500GPM mud system for HDD rig. Below are their requirements on equipment for the 500GPM mud system. GN Solids Control gives solution relatively to optimize the mud system for HDD rig:
1) Customer request on 500GPM mud tank dimension: Mud tank to same as 20 ft standard O.T. container.( Standard frame with container corners for transport on containers vessels and for quick lifting)
GN Solution on the 500GPM mud system tank dimension: It is no problem for exactly same dimension with 20ft container. But GN recommends the tank with a smaller width: 2000mm in order to put into container for shipment.
2) Tank compartment for the 500GPM mud system: Divide the 20 ft mud tank to three chambers – (1) Shale shaker chamber, (2) De-sander chamber, (3) Desilter chamber
GN confirms the 3 chamber of the 500gpm mud tank system
3) Customer request to install bigger shale shaker model GNZS594E with 616 GPM.
GN team confirms the big shaker for 500GPM mud system.
4) Furthermore, customer request install 2 Nos. of big power pump 6×5 centrifugal pump with 45 Kw motor.

And install big capacity mud cleaner (shaker + 2 nos. of de-sander + 12 Nos. of desilter) model GNZJ594E-2S12N with 1056 GPM capacity.
Per the big centrifugal pump and big capacity mud cleaner, GN engineer give solution that: connection shale shaker with mud cleaner shaker with distribution box, controlled by valve, customer can choose to use 1 shaker or 2 shakers. In this case, the mud system can extend to be with 500GPM capacity or 1000GPM capacity.
During 500GPM capacity, the user blocks half of desander cone and half of desilter cone for a better hydraucyclone separation.
5) Regarding mixing system, as customer already have some mud tanks locally, GN offers a separate jet mud mixer for option. Customer can chose it to match with its local mud mixing tank. Or connect the shale shaker tank with its original mud tanks.
The system is easy to shift between 500gpm and 1000gpm capacity. Customer is very happy with professional engineering team of GN Solids Control.
If you have interest on above 500 / 1000 GPM HDD mud system, or you have any special request on no-dig compact mud recycling system, you can contact GN group freely for more information.

Drill pipe is an industrial tubular used to drill into the ground. There are three major industries that use drill pipe. The most common application of drill pipe is in the oil and gas drilling. Another industry that uses drill pipe is the underground construction industry, or more specifically, the Horizontal Directional Drilling (HDD) industry. And finally, the water well drilling industry also uses drill pipe.

The oil and gas industry is where drill pipe is used the most. Another industry that uses drill pipe is the underground construction industry, or more specifically, the Horizontal Directional Drilling (HDD) industry. This industry utilizes drill pipe to bore tunnels underneath waterways, major roadways, and generally any place where trenching is not acceptable. The resulting bore is used for various utility pipelines such as: fiber optic, water, electricity, and oil and gas. HDD drilling rigs are very different from oilfield drilling rigs in that they are almost completely laying flat or horizontal. Most of the larger (Maxi) HDD rigs use exactly the same drill pipe that the oilfield uses.

HDD drill pipe have a variety of models. Different brand HDD machine have different drill pipe standard.  Usually, the length and thickness of the dill pipe are similar, but the thread of the connector are different.

Vermeer and Ditch Witch are the most 2 famous manufacturer for HDD drill pipe, while GN Solids Control is the most professional for HDD mud recycling system.
