GN Solids Control is one of the world famous solid control and waste management companies which specializes in manufacturing the related equipment, such as shale shaker, desander, desilter, mud cleaner, vacuum degasser, mud gas separator, decanter centrifuge, agitator, centrifugal pump, cutting dryer, screw pump, shear pump, mud gun and so on. All of the product line are used in the oil and gas drilling, mining drilling, HDD, TBM and many trenchless area.

The trenchless technology is also called “non-dig” which is often used in the oil and gas pipeline laying, or the underground pipe repairing without digging the ground surface. This can specially used in the densely populated area without disturbing the normal life of the local residents. Before laying the pipeline or doing the repairing job, the contracting company will need to do the HDD work, that is horizontal directional drilling, to dig to the underground and finish the job. During the drilling process, the contractors will need to use a lot drilling mud, and GN’s new mud mixing system is designed for this job. The mud mixing system consists of several mud mixing tanks and skid mounted jet mud mixing unit. On the mud tanks there are agitators and mud guns, the agitators are used to stir the mud to make it even and keep the good chemical feature. The mud gun is used to spray to corner of the tank to avoid the solids collected there. The jet mud mixing unit is used to add some chemicals to the mud system to keep the mud working in good condition. For the tanks, GN can provide both the rectangular and cylinder tanks, the customer can choose the shape according to their working condition.16.08.19-Mud-Mixing-System
That’s the brief introduction of the GN’s mud mixing system. Hopefully it will be useful  and helpful to you. GN has many more solid control systems, they can be used in different operational situations and help you achieve your target easily and cost effectively.

Consumption of huge quantity of oil and energy has brought great convenience for the development. Drilling oil has become dramatically more important today. There will be this kind of problem in the oil drilling process. GN Solids Control(China) mud recycle systems avoid such problems, we need a good selection in the choice of equipment to avoid incidents happen.

Shale shakers are often used in the drilling process. I think we normally have found that drilling fluids overflow phenomenon. Let’s look at the following information which may give your ideas.

Drilling fluids factors

1, Mud or drilling fluids viscosity is too high. They are clogged on the shaker screen and stop drilling fluids flowing across the shaker screen.

2, the large mud weight may cause the same problem

3, the solid percentage of drilling fluids is too high

4, cuttings dispersed.

Negative shaker performance factors:

1, the G-force or vibration force is not enough;

2, screen mesh or screen API number is too high, the penetration rate of shaker screen is relative low;

3, the effective area of ​​shaker screen is too narrow

4, vibration track determines the mud transport speed;

5, Choosing inappropriate shaker screen, drilling fluids accidently flow to both side of shaker screen. So drilling fluid can not flow equally all over the shaker screen

How to avoid overflow happen and do the appropriately shale shaker maintenance:

  1. Appropriately adjust the deck angle in order to process more fluids;

2 .  Set up vibration motor and obtain high vibration force

3 .  Carefully read information of shaker treating capacity before purchase the unit

4 . If the shaker screen is blocked, we should immediately wash out solids/particle

5.  Once the shale shaker shut down, operator should clean the whole units and surface of screen. Otherwise, the mud will block the shaker screen.

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.

HDD (Horizontal Directional Drilling) rigs are nowadays part of pipeline construction projects. This increasing trenchless technology contributes a technical and economic edge as well as providing environmental and productivity advantages. For under-river crossings, traffic way crossings, flood protection dams,crossings below foundations of buildings or objects, nature reserves, parks or even whole city areas or mountain zone, different size and type HDD rigs are used for pipeline laying projects of different lengths, depths, geology as well as technical and environment conditions.

HDD Drilling Rig

How HDD Rigs Drill the Pipeline Guiding Hole

Before drilling, the operator will dig a small well on the ground and predetermine the drilling route. In the drilling bit, there is a signal bar which is used to make the drilling bit drill as per the desired direction.
As the drilling pipe get into the ground is gradient and also out of the ground upwards gradient, the drilling route looks like a inverted parabola.
After the drill bit out of ground from the desired point, always other side of river, road or mountains, we would get drilling guide hole. Then, larger drill bit, also called reamer, would be installed on the drill pipe to drill again along the hole so that to make the hole diameter larger. Several larger reamer would be used to make the hole diameter is larger than the diameter of the pipeline which would be laid later.

HDD Mud System Application During Drilling

In order to prevent the collapse of the hole wall and lubricate the drilling bit, the drilling mud would be used during the whole drilling operation.
Herewith, we would give a brife introduction for HDD mud system. Generally, one unit complete HDD mud system would consist mud tank, shale shaker, desander, desilter, mud mixing unit and pumps to transfer the recycled mud back to the rig. Nowadays, almost all the HDD contractor would equip the rig with one unit mud system for drilling mud cost saving and environment protection.

How HDD Rigs Lay the Pipe Underground

The pipeline is welded at the drilling bit out point and connected to the drilling pipe. Then the HDD rig would pull back the drilling pipe, the pipe also would be pulled into the drilling hole. Thus the pipe is laid without digging a ditch on the ground.
