Generally a solids control system will have all the 4 stages separation equipment for drilling cuttings and fluids. However, not all the equipment would have to be used when drilling. Hence, it will be better to design an overflow line for the drilling fluids on the mud tank to let the drilling fluids could flow bypass the equipment will not be used in some specific process.
In generally condition, the overflow line is designed as a U type slot on one side of the mud tank top. It is starting from the sand trap compartment of the mud tank to at least the suction tank where the high pressure mud pump could suck the active drilling fluids and transfer to the rig. As per customers’ requirements, this overflow line could extend to the drilling fluids mixing tank and storage tank.

Shale shaker, de-sander, de-silter and decanter centrifuge are seen as the 4 stages of solids control equipment which can finally separate out the cuttings with size down to 2-5 microns. In some solids control system, there will also have vacuum degasser located between the shale shaker and cyclone units. This degasser is used to remove the entrapped gas in the drilling fluids like CO2. However, this degasser unit is not used very often.
When the time no need start this machine, we can close the gate on the overflow line to the degasser sucking compartment, and then the drilling fluids could flow directly to the de-sander compartment after treated by the shale shaker. Even, sometimes then no need the cyclone unit, the drilling fluids could flow into the centrifuge feeding compartment. This always happens at the beginning time of the drilling as there is not much cuttings in the drilling fluids.
By opening or closing the gate between the overflow line and each compartment of the mud tank. The mud engineer could guide the drilling fluids flow so than do a better control of the solids control system. You know, turn off the equipment will not be used temporally will save a lot when drilling, and that is also a protection on the machine.
Knowing how the overflow line works would be much helpful for us to design the drilling fluids solids control system. Once the system arrives at the drilling site, this could greatly help to increase the working efficiency.

As the first solids control company in China getting vertical cutting dryer this year and the years to come, Hebei GN Solids Control Co., Ltd has been foremost the drilling waste management technology in China with the birth connected with complete drilling waste management system which are now portion in over 10 value packs around the world. Over three pieces are in Africa where our own after sales team is doing having service now, one arranged is in Cyprus for ocean going oil based drilling cuttings therapy. Eights sets are in Italy including four sets provided last December for Baker Hughes. Yesterday, the 9th drilling waste management system is delivered to Russia together with customized insulation covers to get winterization in Russia. It is evident that many solids control vendors in China can producer and provide vertical cutting dryer and drilling waste management system, and GN Solids Control is not the one on lowest price. What GN discover is the high quality at a cost-effective and competitive price. Here is why GN Solids Control finally win many jobs after customers visit every one of the suppliers in China.

The actual ninth set of drilling waste material management system to The ussr is designed to operate in frosty winter as it always is within Russia with a container as well as heat reservation cover. This specific sets of drilling waste materials management system totally consists of one set vertical cutting dryer with the G drive up to 750 at a twelve hundred RPM and flushing system to avoid blinding on screen basket and at liquids produce channel, two sets decanter centrifuge with one to get solids control the other for more waste treatment, three pieces screw conveyor with a couple of for feeding the up and down cutting dryer and one to get transporting dried powders, in addition to three sets screw pump with one for flushing and two for providing the decanter centrifuge.

One set 500GPM drilling mud recycling system was sent to Middle East for water well drilling. Besides the drilling mud recycling system for oil drilling, they also need drill water well for daily requirement for clean water. For the person living in Middle East, water is more important than oil. Sounds like a joke, but this is reality.
Water well is not so deep like the oil well, and the drilling cost is also very cheap comparing with oil drilling. However, both this 2 drilling processes need the drilling mud recycling system to speed up the drilling process and protect the drill bit. Water well drilling may not need the used drilling mud to be separated very clean as it is not requested strictly. Just like this 500GPM unit shipped to Middle East, it is a very compact
model, while it has all the necessary separation equipment.

It has one unit shale shaker GNZS703DZ with 3 panel screens which could remove out the solids always larger than 300 microns. This model is with the mud feeder on top of the shaker deck so that this shaker could be much more compact. As the water well drilling is always not so deep, hence, the solids coming out with the drilling mud is always not so hard. In this 500GPM mud recycling system, the de-sander cone is not equipped, but directly the de-silter cone would be used to separate the solids size of around 20 microns.
This 500GPM water well drilling mud system is a standard GN model GNMS-500G with 2 unit centrifugal pumps. One of each is used as feeding pump for the de-silter cyclone, and the other one is used for mud mixing, the mud tank is divided into 2 compartments. It has enough space for clean mud storage.
Though this 500GPM mud system is for water well drilling, it can also be used in other drilling project like HDD. As the working principle is completely the same. The customer killed two birds with only one stone.

Pitless means no need to dig a pit on the ground to collect the drilling cuttings. Nowadays, though the solids control system is widely used in oil drilling, some drillers still dig a mud pit on the ground to collect the drilling waste cuttings discharged out from the primary solids control equipment.
So long as the drilling rig is working, the solids control system has to be working all the time as the used drilling fluids is continuously coming out from the drilling well. With the issue of much strict environment protection regulation, the driller need find a solution to reduce the volume of the discharged drilling cuttings; in the meanwhile, much more drilling fluids could be recovered to reduce the drilling cost. And then they got a
conclusion, if I can establish a pitless drilling cutting disposal system, all the problems would be solved.

Pitless drilling cuttings disposal system requires a good connection between the traditional solids control system and waste cuttings management system. The most important is there should be a final solution on how to make the discharges environmental friendly. For the waste cuttings out of the shale shaker and cyclone unit, no matter water base or oil base. We have the high G force drying shaker and vertical cutting dryer unit to make the cutting much dryer so that more drilling fluids could be recovered. The recovered drilling fluids would be pumped
to a high speed centrifuge for separation of fine solids in the drilling fluids. After treated by the centrifuge, the drilling fluids would flow back into the storage tank for drilling reuse. The screw conveyor is used to transfer the drilling cuttings from shaker unit to the cuttings dryer machine. Therefore, it is no need to dig a mud pit, or at least, a large and deep mud pit on the ground to collect the drilling cuttings. We nearly realize
the pitless before the final disposal of the dry cuttings.
There are Thermal Desorption Unit and solidification unit could be used to dispose the cuttings from the high G force drying shaker and Verti G dryer. These 2 systems could make the cuttings none hazardous for environment. Finally, the pitless drilling cuttings disposal system is established.

All large capacity drilling projects such as oil gas drilling, no dig drilling for pipeline laying and water well drilling need drilling fluids when doing the drilling job. There is one type equipment naming shear pump that is an ideal choice for drilling fluids mixing. We could see the drilling fluids as the blood of the drilling equipment.

Here, how to make the drilling blood clean and let the blood perform well is so important to all the drillers. It is known that the drilling project need a drilling fluids recycling system, or we call it mud recycling system. Before start drilling, we need get the mud recycling system ready. On the other hand, we need the drilling fluids to be ready. The drilling fluid is a mixture of water/oil and some mud materials like barite, bentonite, and some other chemical agents. Among the various mud materials, the bentonite is the most important one and the consumption is quite big. Meanwhile, the bentonite is also a polymer which is difficult to solve into the drilling mud base.

Then how should we resolve this problem? Bingo! We need a shear pump. Thanks to the special design of the impeller, the shear pump could cut the polymer into very small pieces so that these materials could solve into the water easily. A high efficiency shear pump could make the consumption of bentonite reduce 30%. Oh my god! Really a large cost saving.

This is not the only advantage to use a shear pump to cut the polymers. Once the drilling started, the solids control equipment will also start running. When the used drilling fluid comes out from the well whole and flow into the shale shaker, the mud recycling process is beginning. If there is much long strips material in the drilling fluids, the screen will be blocked which leads to loss of polymers.
One thing the drilling fluids engineers need pay attention is the shear pump cannot run without fluids inside the pump. As you know, the shear pump is use centrifugal type pump, it need run with liquid to reduce centrifugal force so that the fluids can be transferred continuously. One more, the shear pump cannot be used to transfer used/active mud, as the cuttings in the used mud will definitely damage the pump parts.

Recently GN Solids Control exported a oil drilling rig mud system for a 1500hp oil rig in Russia, with our partner supplying the mud tanks. GN supplying all the main equipment like shale shaker, mud cleaner, decanter centrifuges, centrifugal pumps.

A normal 1500HP oil drilling rig developed with a 350 t hook load capacity for medium deep wells. Every aspect of rig operation from mobility and deployment to machine and structural design has benefited from a wide array of improvements that maximize safety while minimizing the time for rig-up/down and transport. An integrated hydraulic system is connected to raise the mast and the substructure. When the substructure is in the lowered position, the mast is connected to the drill floor. The mast is raised by two hydraulic cylinders. When the mast is in the vertical position then the hydraulic cylinders are disconnected and retracted. Two telescoping cylinders now lift the substructure into operational height.

The particular mud tank can be personalized as per clients request, typically the 40 feet or twenty feet size just for move convenient in side from the country. Some client buy mud tank with skid mounted which can be pull regarding moving mud tank to put it briefly distance.

Mud gun is definitely an essential part for going mud tanks, it generally works together with mud agitator/ dirt mixer. The 3 main features including:
(1) Mixing, prevent the shades from precipitate, the necessary operating pressure is provided by the blending pump or mud pump motor, sometimes it works together with mud whisk, for example , for mud combining tank, mud storage container; sometimes it works separately if you find no enough place to use a mud agitator.

(2) Transferring, the actual mud gun line was created inside the mud tanks as well as connect with each tank in order to transfer the drilling liquids, for example , it can work as an account balance pipe between 2 aquariums to keep the mud degree balanced.
(3) Cleaning: If linked to clear water pump, it may be used as mud container cleaning line after going is finished, so you do not need to purchase a separate jet water device, with the GN unique dirt tank bottom design( having a 5 degree slant), the actual deposits solids on the container bottom will be washed aside with sand washing slot, and the operator can use unique tools to take the fine sand away.

For the mining, GN have made a few customised layout systems, the first one is for Poultry, the customer co-design the system along with GN; then for the coring ming project, we style and design a very small system to get diamond drilling; then some decanter centrifuge with different layout for mining or prospecting water; now another customized system for Philippine mining or prospecting project.
This system contains a shale shaker, two centrifuges. The problems delivered to us is: deep subway, have mining water, having mixtures, different particles, which will destroys the pump which usually keep pumping the lakes and rivers out to keep it able to perform there. The pump is created in German, good quality, but expensive, we want to keep it within good condition, and not easy to get repalcement parts. To sum up, we need another technique to make the pump running properly.
Then we tried a variety of choices, to keep it below ground, or keep it along with the land. To only start using a centrifuge, or use several centrifuges. And questions continually come like do we need shaker, do we need desnader and many others.

With the professional help from clients’ engineer, we finally what is design, and also modify this current operation flow of the mining or prospecting water. Then finally detox the singing water, and then transport to the surface. Considering that the purpose is not for consuming, so do not try.

Furthermore in the mud recycling system, it contains 2 Nemo pump, which is manufactured by German Netsch.

Specifications connected with decanter centrifuge
we have VFD cp to achieve stepless bowl rate adjustment to enhance mud treatment method performance
we use De dos niveles stainless steel SS2205 for centrifuge casting to improve bowl sense of balance, centrifuge balance, as well as progress performance on corrosion weight.
We use Tungsten carbide tiles protecting the twist conveyor impellers to enhance the particular performance when treating large mud.
When the system appear the site, GN solids control engineers should go to the site for the first time having and also operator training. To be sure all goes well and the right way.
