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.

Almost every kind of drilling will request drilling mud or drilling fluid as we call it. There will be drilling cuttings invade to drilling mud during drillings. So we need solids control or other drilling mud process on drilling fluids during well drilling or HDD. This will decrease much cost on drillings.

During solids control, centrifugal pump is mainly treated as power for transfering fluid from equipment to another, from one compartment to another one

Solids control system configuration

Usually, the solids control system is 4 phases. Including shale shaker, Desander, Desilter, or mud conditioner, then the decanter centrifuge. This configuration is considered as modular configuration. However, we also know, different clients have different requirements on certain drilling conditions, etc. So the system will be combined with standard equipments as optimal system for individual users

After knowing the solids control systems cocnfiguration, we’ll get how many centrifugal pumps we need. And in each specific system configuration centrifugal pump will have certain special applications


Centrifugal pump applications in system

1. Different centrifugal pumps

In solids control system or mud recycling system. There is usually two types centrifugal pump. Including vertical centrifugal pump mainly is subermsible slurry pump and horizontal pump.

If in HDD mud recycling system, there maybe submersible slurry pump to suck drilling mud from mud pit. Of cours, submersible slurry pump also can be treated as feeding pump for desander, desilter, or mud cleaners.

Solids Control Centrifugal Pump

Solids Control Centrifugal Pump

For majority solids control system, to feed desander, desilter and mud cleaner will use horizontal centrifugal pump. The applications is pump drilling fluid from one space to another. Make drilling mud having power to flow during serveral compartment and equipments

2. Detailed centrifugal pump applications

Take mud cleaner for example. The drilling mud after processed by shale shaker will drop down to shale shaker compartment, then we need to process it by mud cleaner. Firstly, centrifugal pump will transferr drilling fluid from this compartment to desander cones, after desander processing the mud drop down to desander compartment.

We need drilling mud more fine and high property. Then we come to desilter. At this time, centrifugal pump will pump drilling fluid to desilter cones. Then we’ll get relative clean mud without particles larger than 15 microns

If you are looking for desanding equipment for micro-tunneling, horizontal Directional Drilling(HDD), water well and environmental vertical drilling or rotary drilling, slurry separation system, etc underground construction applications, GN desanding equipments are your best choice.

desanding equipment

desanding equipment

GN Desanding system including the following equipments. 1 Desander with 10 inch polyurethane hydrocyclone( 2 pcs or 1 pc, depends on the required treatment capacity of the end-user)

2 Desilter with 4 inch polyurethane cone( 8~12pcs)

We can offer the desander and desilter with two types, with underflow shaker or without. Some client need the underflow shaker to collect the treated mud by hydrocyclones, so the clean mud will not be wasted. That is why many clients use high mesh desander/desilter screen so it can separate slight particles.

If the cones numbers exceed 16pcs, it is better to use a large underflow shaker, such as GNZS63-3 shaker, GNZS83-2 shaker, otherwise it will lead to overflow, because the treating capacity of cones are rising, but the flow rate of shaker is not large enough, even it use a high mesh screen.

As a desander and desilter manufacturer,we also make feeding centrifugal pumps for feeding the hydrocyclones.As required by clients,sometimes we offer centrifugal pumps with mechanical seals.

The advantages of mechanical seals centrifugal pump over compression packing or glands are:

Desander Desilter Feeding Pump

Desander Desilter Feeding Pump

1) Mechanical seals  ensures sand pump almost zero or very little (as per the regulations) leakage of the fluid from the pump casing to the surroundings.

2) The mechanical seals pump can sustain high pressures of the fluids and highly corrosive fluids. There is always some leakage from the compressible packing and sometimes they tend to fail under the deteriorating effects of the chemicals, but such problems do not occur with the mechanical seals.

3) There is no friction between the moving parts of the mechanical seal so there is no extra power consumption by the centrifugal pump. Continue reading »
