Mud cleaning system is two main parts, the storage mud tank on below and many machines serve as purify the drilling fluid, which get rid of the solid debris in drilling fluid. The mud tanks which store drilling fluid are divided into circulation tanks and store tanks. Circulation tanks as a part of the filter cycle, there are shale shaker, vacuum degasser, deserter, and desander and decanter centrifuge on the top of tank.

The 1st level of purification
the drilling mud pumped away from the rig and flow-down in the shale shaker. The allocation drilling fluid enter into the bottom of the drilling well under the foundation of the drilling pump and carry drilling debris return the ground, through the elevated tubes enter into the shale shaker, the larger solid debris in drilling fluid are filtered through screen

Desander with GNZS752 Series Mini Shale Shaker

The2nd level of purification
When drilling fluid have debris contain gas, The use of vacuum degasser remove the gas which in the drilling fluid and can recover the density of drilling fluid, calm the drilling fluid viscosity.

The 3rd level of purification
the drilling fluid is disposed by two levels, mud purification enters into the desander.  Through the desander feed into the liquid pump, the harmful sold phase which the diameter is above 40-60um is separated in desander.

The 4th level of purification
the drilling fluid is disposed by the three level purification enter into the desilter through the desilter feed into the liquid pump, the harmful sold phase which the diameter is above 15-40um is separated in desilter.

The 5th level of purification
The drilling is disposed by the four level purification enter into the decanter centrifuge through the centrifugal feed liquid pump, the small harmful sold phase particles are separated in decanter centrifugal.

Usually, all five purification is all working at the same time. If it works one equipment or several equipments, the parameters of the drilling fluid can all meet the work requirements; it can work in one equipment or in several equipments. After the purification, drilling fluid can re-use in the drilling cycle

GN Solids Control is China leading company to manufacture the solids controls equipment and drilling waste management equipment. Shale shaker as the first phase separation equipment at mud circulation system, play an important role in the system. Our company founded 7 years before and we start the shale shaker design and production from then.  Until now, GN shale shaker have been exported to over 60 countries and areas for oil drilling application.

For now, GN Solids Control have different type shale shakers for option,  2 panel shaker, 3 panel shaker and 4 panel shakers. The client can choose the proper model to fit their unique project

.shale shaker

2 panel shaker GNZS752E is mostly used in non oil drilling industry. Most of client buy the mini shaker for diamond drilling or waste water treatment.

3 panel shaker is mostly used in HDD drilling, waste water drilling and Workover rig mud cleaning system. Some client also use the 3 panel shaker for oil drilling project.

4 panel shaker is most popular in oil drilling project. The shaker with longer deck can have better treating performance, mostly used in 500gpm mud system, 1000gpm mud sytem, 1500gpm mud system.

GN 4 panel shaker is replacement for Swaco Mongoose shaker. We have same type shaker screen which is replacement for Swaco Mongoose composite material shaker screens. Cheaper price carbon steel frame material screen is also available.f

GN 4 panel shaker can also be used for drilling waste management, water based mud drilling cuttings drying process. We call the shaker High G drying shaker or High G dryer in drilling waste management. After treated by GN high G drying shaker, the OOC can be reduced to about 10%, and the valuable Water based mud can be collected for reuse and the dry cuttings can be buries for permanent stock.

For oil based mud cuttings treatment, we recommend Vertical cuttings dryer for better performance, the OOC can be reduced to below 5%. OBM cuttings are more hazardous to environment and need to be taken care of more carefully.

GN Solids Control centrifuge is high quality with reasonable price, centrifuge operation is also very important. And it require operator with many years experience or with training certificate from professional centrifuge supplier. In many cases, centrifuge problem is because of non-professional operation, not centrifuge itself.

For example, one centrifuge is used for treating the mud after vertical cuttings dryer. The mud discharged from vertical cuttings dryer is very heavy mud with high density, viscosity and not good flowability. In this case, if you feed the centrifuge directly, the feed pump will not work well and the centrifuge is easy to trip off. Our suggestion is the client can design one holding tank between the vertical cuttings dryer & the centrifuge, install one agitator in the mud tank to suspend the drilling mud and adding water if necessary to lower down the density of the mud. The centrifuge will surely working very fine under professional operations.

Another, vertical cuttings dryer block and trip off sometime, why?  This is self protection of the vertical cuttings dryer when faced with wrong operation. We recommend the engineers to select the proper material for dryer. For example, it is not good to use vertical dryer to treat the mud waste discharged from mud cleaners & centrifuge. Because the separation point of the vertical dryer is about 0.5mm; however, the particles discharged from mud cleaner & centrifuge is much smaller than 0.5mm, around some hundred microns or even smaller than 100microns. In this case, the vertical dryer screen basket is easy to block, not good performance. The vertical cuttings dryer is very picky, it can only treat the drilling cuttings discharged from shale shaker.

Except for centrifuge and dryer, other equipment like shale shaker, mud cleaner, agitator, centrifugal pump is much easier operation. The shaker have to use proper deck angle and replace the shaker screens when necessary, mud agitator need to add gear oil for the gearbox, the centrifugal pump also need lubrication oil. Pls follow the instructions on label or user manual to do correct oil lubrication.

Check energy current to find out if it’s normal before turn the motor on.

Check all of the bolts are correctly tighten before turn the motor on.

Check the entire shaker screen is correctly secure with wedge block.

See if there are any foreign objects around the shale shaker.

Once the cleaner operate at normal condition, there must be minimum noise and also the operation ought to be smooth and steady, if there’s any unusual noise, stop and appearance the gear immediately.

When the connection cable between vibration motor and also the control panel continues to be transformed due to maintenance or altering motor, the cleaner won’t work efficiently. It requires remove the shield in the finish from the vibration motor, connect the energy and observe if the rotation directions of these two vibration motors are other direction. Otherwise, it needs adapt to be other direction.

When alter the vibration motor, adjust the rotate blocks around the two vibration motors to become consistent.

After tighten the bolts of vibration motor, possess a check every 8 hrs, if there’s any release, and tighten it.

Once the vibration employed for about 500 hrs, inject a number of specific lubricant grease (about 80g).

The control switch is explosion-proof, don’t open if it is necessary. If have to look for problem, it requires switch off the energy first. When look into the equipment for possible problem, don’t let yourself be neglected particulars or wrong installed, to be sure the explosion-proof.

The wedge of shaker screen ought to be checked each 8 hour, if there’s any problem of release, tighten it promptly.

With compact the shaker screen, the strain pressure of every bolt is 5KN.

Once the mud cleaner can be used for 1000 hrs, some lubricating grease ought to be injected in to the grease box.

When the springs broken, alter the springs as quickly as possible. When altering the springs, the screen box ought to be elevated, and set the springs around the spring bases, then ease-lower the screen box.
