Earth boring is drilling a hole, tunnel, or well in the earth. Boring is applied for any wide variety of applications in geology, agriculture, hydrology, civil engineering, and oil and all-natural gas industries. Whatever type of earth boring, you’ll need increase a good deal of mud/slurry, you’ve to locate a appropriate option to procedure these mud /slurry. GN mud cleaning equipments is usually applied for all kinds of earth boring.
The most popular earth boring projects such as:
1 oil & gas drilling, utilised Mud Cleaning System to separate big solids from the drilling fluids and recycle the clean drilling mud
2 mining core boring,applied to separate the fine silts from the slurry
3 railway tunnelling or Underground Railway, used to separate big rocks from the bentonite slurry which is increased from Tunnelling boring Machine.Micro-tunneling is similar project, just the flow rate per hour is smaller for the mud cleaning system.
4 Civil engineering, like pipeline crossing, after crossing, you can not just leave the mud there, most of these projects are inside the city, you must cleaning the mud and reuse or use a truck to drain off it.
5 Bored piles
GN mud cleaning equipments/ system including shale shaker( for civil construction ususally it is double deck shale shaker, the upper shaker screen is used as first phase cleaning of the big rocks, the bottom shaker screen works to separate the fine solids, such double deck shale shaker can enlarge the treating capacity in the same cost)., mud cleaner( shale shaker with hydrocyclones, sometimes we put hydrocyclone on top of the double deck shaker to save room for bored piles desanding).
The accessories such as mud tank, mud agitator, mud gun, mixing hopper, mixng pump, etc.
Different industries will require different treating capacity mud cleaning equipments, for example, TBM usually have to have a big treating capacity mud system up to 500m3/h, but mud system for micro-tunneling is much smaller. The required flow rate for pipeline crossing in civil construction is usually 500gpm, 800gpm, 1000gpm.
GN solids control engineer teams have many years experience for the customized mud cleaning system for the above application in civil construction, welcome to contact us for any option of mud.

For earth surface engineering, the contractor no would like to take into consideration about combustible gas or explosive gas, like HDD no-dig engineering, piling engineering, tunneling engineering, waterway dredging engineering. But for deep drilling engineering, like oil & gas drilling, Coal bed methane drilling, shale gas drilling, all the motor and control panel should be ex-proof standard. The standard should also separately as per different geological conditions. Some security equipment is also necessary.
1) Mud Gas Separator ( poor boy degasser) ?a security equipment in solids control system for deep drilling
When gas cuttings happened to drilling fluid, the gravity and viscosity of drilling mud will be changed a lot and cannot satisfy the requirement for drilling, even lead to kick or blowout accident. The mud gas separator , made of high quality material , can be used to separate the harmful gas effectively.
GN Solids Control can supply the best quality mud gas separator with other solids control equipment, like shale shaker, decanter centrifuge, mud cleaner etc.

2) Flare Ignition Device¨Csecurity equipment in solids control system for deep drilling
The flare ignition device is used to follow the mud gas separator. After the explosive gas, like sulfuretted hydrogen, methane, carbon monoxide, removed by mud gas separator, the explosive gas will be transferred to flare ignition device via rubber hose and fired. After fired, the explosive gas will become carbon dioxide and water.
GN Solids Control can supply the best quality flare ignition device with solids control equipment spare parts, like desander cones and desilter cones for gas mud cleaner,shaker screen for shale shaker.

3) Ex-proof motor and Ex-proof electrical control panel
The Ex-proof motor can be classified into ordinary explosion-proof motor and EX-proof motor with IEC or ATEX certificate. The ordinary EX-proof motor can satisfy the most drilling conditions; In some extremely complex environment, EX-proof motor with IEC or ATEX is necessary. Electrical control panel is the same thing as motor, ordinary EX-proof control panel and EX-proof control panel with IEC or ATEX certificate.
The ordinary motor and control panel can satisfy for the Zone II; the IEC or ATEX standard can be used in Zone I area. Zone I means ? Under normal circumstances, explosive mixture gas may appear?±; Zone II means ?° under normal conditions the explosive gas mixture will not appear ; only in unusual circumstances, the explosive gas mixture may appear occasionally?
GN Solids America can offer motor and control panel satisfy Class I, Zone I and Class I, Zone II. GN Solids Control can offer different standard for different requirement from end user.

The gn america model solids manage technological innovation is actually a mobile closed-loop unit engineered to time, labor and set up fees. The model can do the job standalone or being a supplement to USA Mud cleaner. It could possibly move around in, rig up and feel working on spot inside of two hours of arrival.


The solids control operates in 3 processing modes, determined by the distinct application and necessities:

High-volume. Drilling fluid is drawn from your rig through the 6-in. suction line and into two entirely variable-speed-centrifugal feed pumps within the pump space. They, in turn, move the fluid to the two fully-variable-speed centrifuges. The centrifuges are mounted atop the pump space to ensure the solids can discard in to the catch-tank portion on the trailer even though the liquid effluent returns to your tanks mounted beneath, inside the pump room. The effluent then returns to the rig by way of a separate fully-variable-speed centrifugal pump in the similar price as the fluid getting into the tanks.

Dewatering. This mode is just like higher volume processing, but with an additional chemical-injection line tapped into both centrifuge feed pumps. Drilling fluids are flocculated on the fly even though flowing toward the centrifuge-feed piping. Clear-water effluent is piped right in to the effluent tank for instant, metered return to your rig via the automation package deal and level controls. The flocculated solids are discarded right in to the trailer?

Operators can switch the centrifugal feed pumps from parallel to series operation. While in the series mode, the No. 1 centrifuge processes mud in very low pace operation as well as effluent returns on the polishing tank. There, it really is polished by way of the No. two Mud cleaner. The barite recovered in the to start with centrifuge passes straight into the slurry tank mounted during the pump space, in addition to the polished effluent from your No. two centrifuge.


model was engineered for land rigs not equipped to complete specialized solids-control operations and don’t demand these abilities although drilling the complete effectively.

presents these operations barite recovery, high-capacity processing, dewatering and/or mud stripping.

Far better solids elimination to reduce dilution and waste volumes

Fully-variable speed- centrifuge technologies lowers the percentage of liquid on cuttings, even though the whole model package deal is completely contained in order to avoid any liquid/solid spills

Improved solids removal efficiency

In 1 set complete drilling mud cleaning system, we could find six pipeline system. They are Overflow launder pipeline, clean water pipeline, mud gun pipeline, active mud suction pipeline, mud mixing pipeline and drilling hole mud replenishment pipeline.

Overflow launder pipeline is the most important pipeline in the mud system. From the Shale shaker compartment fo the tank, there will be a launder uphill through the desander tank, desilter tank in order to prevent the drilling mud overflow out of the tank.

The clean water pipeline is used to clean the tank, it is connected with the clean water tank or a water faucet and installed opening controled by valve in each tank.

Mud gun is always powered by mud pump in a mud system for oil drilling rig. The high pressure could transfer the active mud to each tank from the begainning of the desilter tank to make the replenishment or prevent the mud sediment. While in small mud systme, the mud gun often powered by mixing pump. Some mud system will have a trip tank, also we will install mud gun there.

In large mud system, mud pump could suction the active mud from every tank behind the desander tank. All the tanks storaging active mud is connected by the mud suction pipeline.

Mud mixing pump is used to mix the drilling mud in the tanks. Where there is the active mud in the tank, the mixing pump could suction it, after treatment by adding some drilling chemical then transfer them back by mud mixing pipeline.

the drilling hole mud replenishment pipeline is connected to wellhead, when the drilling bit raise out of the hoel, the drilling mud will be pump into the drilling hole to keep the well pressure and protect the well wall. When the drilling pit again down, the drilling mud will backflow to the trip tank.

The above mentioned six pipeline system could be find in 1 set complete large mud system and all of them functioned irreplaceable. Welcome for your comments and let’s learn it together
