Drilling fluid equipment contains solids control equipments, mud moniter equipment, mud pump, jet mud mixing euipments and so on. GN Solids Control is a professional company at solids control equipments, (sometimes, drilling fluid equipment is equil to solids control equipments, as countries and persons are different), and got the API certificated in Nov, 2010.

GN solids control is customer concentrited, so usually, if the customer want drilling fluid equipments, firstly they asked GN about solids control equipments, then to find the other products like mud pump, in a economic and effective way, they got the recommendation of GN to find the outstanding companies as GN.

As we all know, drilling fluid is very important in the drilling works, no matter water based or oil based or others. While GN Solids Control only produce equipments for mud rotary drilling.

GN-MRS500 mud recycling system is a modulized system for HDD, and it is very popular all over the world.

This GN-MRS500 system contains:
1 GNZS 83-3 shale shaker;
1 GNZJ 83-3 mud cleaner;
2 SB5x4-14 centrifugal pump;
1 JBQ7.5 mud agitator;
1 SLH150-35 jet mud mixer; Continue reading “Introduction of GN-MRS500 mud recycling system”

Drilling mud is a important part for the drilling work to maintain the wellbore; Cool, lubricate and support the bit and drilling assembly and so on, most important, remove cuttings from well. Then here it problem, to reuse the drilling mud. Then it is the time for mud circulating system to come here.

In some applications, the mud circulating system is equal to solids control system, but the full mud circulating system in drilling work, contains more. Except for the four phase, five equipments as we know, shale shaker, vacuum degasser, desander and desilter (or mud cleaner), decanter centrifuge. There also include mud pump, electric generator, control panel, chemical reagent treatment unit, and so on.

As you can see in the picture. It is used for the movable drilling rig, and also this system is movable. Usuall solids control equipments can not prevent the loss of the drilling mud. So we also must add chemic to the tanks to add fresh drilling fluids. Other parts are also very important, centrifugal pump, mud agitator, mud gun.

Slurry treatment system is very important for slurry tunnel boring. GN Solids Control is also very professional at TBM (Tunnel Boring Machine) slurry treatment system. The picture beside is the most popular slurry treatment system. It usually contains a linear motion shale shaker (GNZS63-3, or GNZS83-3), and a mud cleaner, hydro-cyclones with linear motion shale shaker (GNZS63-3, or GNZS83-3). Also mud tank for storage, centrifugal pump to transport.
