GN solids control is specialist of solids control equipments for rotary rig in China, we have various kinds of mud equipments in stock, welcome to inquiry us.
Rotary rigs drill the vast majority of wells today, including all medium and deep wells. The rotary rig consists of four major systems. These include the engines, and the hoisting, rotating, and mud systems.
 rotary rig equipments General of drilling mud(drilling fluids)
Common drilling mud is made of bentonite clay. A heavier drilling mud can be made by adding barite. Various chemicals are also used in different situations. The drilling mud liquid is usually water but is sometimes oil-based. Drilling mud are described by weight. Water weighs 8.3 pounds per gallon. Average bentonite drilling mud weighs from 9 to 10 ppg. Heavy drilling mud weighs from 15 to 20 pounds per gallon. The heavier the drilling mud, the greater the pressure it exerts on the bottom of the well.
Fluid is circulated while the drilling proceeds. Powerful pumps move the fluid down to the pipe, through the bit and back to the surface, carrying the cuttings and other debris with it. Thus, on a rotary rig , drilling can be continuous as stopping to bail the cuttings is no longer required. The drilling mud also stabilizes the walls of the hole.
Mud circulation system for rotary rig
Drilling mud is stored in steel mud pits beside the rig. The drilling mud then flows down through the hollow rotating drill string and jets out through holes in the drilling bit on the bottom of the well. The drilling mud picks cuttings from the bottom of the well. It flows up the well in the space between the rotating drill string and well walls.

 GNZS63-4 shale shaker What consist of GNZS63-4 shale shaker?
Deck adjustment, vibration motor, shaker deck, base frame, support, baffle box, explosion proof starter, shaker screen, wedge plate, torsional spring ,etc.
Feature of GNZS63-4 shale shaker
(1). Adopt two sets same vibration motor take advantage of double motor in-phase principle, shaker deck makes linear motion vibration at 45°sling angle, some spare parts are interchangeable with other brand shale shaker
(2). Adopts high quality reliable vibration motor provides long time operation without any problem.
(3). Shaker screen can be flat type or pyramid one. According to drilling mud property the screen can be 10~200mesh
(4) Shaker screen will be tensioned by wedge plate, this is more convenient and easy for operation it is very reliable
(5) Shaker deck is adjustable, the adjustment is worm wheel and screw type. Beside shaker deck two sides middle shaft is connecting two worm, when we make adjustment the shaker deck will be consistent and in-phase
(6) The complete shaker body will be treated by sand-blast, paint it by anticorrosive painting so it is more anti-corrosive and better appearance.
Specs of GNZS63-4 shale shaker

GN solids control can design and manufacture the complete line of drilling waste management system, including shale shaker, high G dryer, vertical cutting dryer, decanter centrifuge, screw pump, etc equipments.
The first step for drilling waste management is to separate the solids cutting from the liquid drilling mud. Once solid and liquid drilling waste have been separated, companies can use a variety of technologies and practices to manage the wastes. For some applications, drilling wastes are solidified or stabilized prior to their ultimate management practice. The management technologies and practices can be grouped into three major categories: waste minimization, recycle/reuse, and disposal.
 drilling waste management centrifuge Function of waste minimization
It can reduce volume or impacts of waste, including the following two aspects.
1 minimize generation of drilling waste
2 use mud and additives with lower environmental impacts
Function of recycle/reuse
1 recycling mud
2 roadspreading
3 reuse of cutting for construction purpose
4 restoration of wetlands using cuttings
5 use of Oily cutting as fuel
How to disposal?
1 discharge to Ocean
2 slurry injection
3 onsite burial (pits,landfills)
GN solids control can produce 3 models decanter centrifuge for drilling waste management system.
1 Middle speed centrifuge LWF450x1000N

GN solids control design and manufacture a complete solids control system/drilling mud system for oil & gas drilling, now we need a mud cooling system in our design, to make it more user-friendly. Usually we call the mud cooling system as mud cooler.
Application of mud cooling system
 Scomi Oiltools Mud Cooling System
- Oil, Gas, Geothermal Drilling - cooling drilling fluids
- Oil and Gas Refineries – gas cooling/condensing
- Petro-Chemical – steam condensing
- Power Generation – fluid cooling
- Steel – waste water cooling
In Oil, Gas, Geothermal Drilling ,the Mud Cooling system is used to reduce the temperature of drilling fluid returned to the surface.
In HT / HP wells the temperature of the drilling fluid must be strictly controlled to keep it’s properties within the specified parameters for that particular well. If the temperature of the drilling fluid is allowed to increase then a variety of problems can occur such as high equivalent circulating density (ECD), formation breakdown, lost circulation, packing off, stuck pipe and evaporation of the oil and water phase.
Why use mud cooler?
1 crew safety
2 Reduction of mud temperature in return lines especially important in Oil based systems to be maintained below flash point.
3 reduction of mud temperature reduces the risk of fire, blowouts, and helps provide safer drilling operation/ environment.

GN designed a new patent linear motion shale shaker, GNZS70-3B. It is designed to replace the previous model GNZS70-3 shale shaker, which is found not so economic and practical before.
Specification of GNZS70-3B shale shaker
1 Vibrating mode: Linear motion
2 Single deck shaker with 3 screen panels
 shale shaker 3 Quick lock( wedge technology operation), which enables screen panel replacement in less than one minute. In drilling site operation, time is more important than money, so easy operation of screen replacement is necessary. It enables for an easy ratchet-type installation of the wedges, which eliminates hammer damage to the screens, as well as the paint on the sidewall of the shaker basket. You do not need any tensioning bolts or system, which can provide a small parts inventory, thus enabling cost savings to be realized.
4 Adjustable while drilling (AWD) mechanism enable faster and easier deck angle changes., adjusment from1 degree down hill to .5 degree up hill.
5 Weir height: Until now we still can not provide operational weir height, the weir height of previous model is 900mm, and for the new designed model is 750mm.
6 Available screen types, PWP(flat panel) and PMD(pyramid screen)
7 Available screen area: 29.6m2
8 Feeding method: optional from back or from top tank

Once a client asked some questions about drilling fluid systems, and I think it is very representative, so I just post here, for all your reference.
*How is the fluid transferred between compartments?
If you still confused by this, contact with our sales, maybe you need a more detailed drawing, or more contact.
*Is the coupling between the tanks rigid or flexible, what is the diameter?
Definitely yes
*Are the shakers, desilters, etc.. designed to be removed quickly for transport? Are they fitted to one large skid or individual units?
It depends sometimes, shakers, desilters are conected with the mount with screws. So if you need, it is easy.
*Can the mounting of the shakers, desilters etc.. be reversed if we require to place the tanks on the opposite side of the machine?
If you need, contact with our engineer firstly.
*For cleaning purposes, how are the tanks accessed, are the walkways removable?
Yes, the walkways is removable.
*I would prefer the hopper at ground level as all the fluids can be next to the hopper and it is easier to dispose the bags into a skip. Also in adverse weather conditions, it is easier to mix additives beneath a canopy away from the wind and rain which is something I’d like fitted.
Thank you very much for your information, and we can design the jet mud mixer as you required.
*Can you please provide a quote and specification for a degasser?
That is cool, we not only supply four phase soldis control equipments, and we also supply vacuum degasser, poor boy degasser, centrifugal pump, and shaker screens.
*What is the weight of the tanks with the components removed for transport?
You can find it in the quotation.
*The volume of each compartment?
It is different from systems one another.
