mud cleaner

As China top brand for solids control & drilling waste management manufacturer, GN Solids have awarded the certificate of API, ISO 9001, HSE, CE and CR-TU. With these certificates, GN product can be accepted by many countries, and this is road for GN products going to each rig for service.

With CE certificate, GN got one big order from Europe requiring 3sets shaker, mud cleaner and decanter centrifuge. The order will be used to replace the old solids control equipment in 3sets oil drilling rigs. Why the clients choose GN Solids?  Below chapters will give you more information.

Small water well rig may no need mud system, just requiring drill rig and mud pump. But for deep water well drilling, mud system is also necessary to get better drilling performance, and give better project to the drill rig bit and mud pump.

GN Solids Control mainly focus on oil drilling mud system. And we also have some client from water well drilling project, get mud system from GN; For example, client from Niger, they have 100 water wells project to improve the local life quality, and they bought the rig fro Italy Drillmec brand, and have mud system from GN.

Generally, we can offer 200gpm/500gp/1000gpm mud system, and we have standard model for the mentioned capacity mud system. If required by client, we can also offer customized system. Among the standard system, 500gpm mud system is the most popular, equipped with below items:

1) 1ea shale shaker GNZS703. GN Solids own patent shale shaker with 3 panel can give good performance, reliable working for the mud treatment, and we can offer coarse steel screen with much longer lifetime to fit for the system.

2) 1ea mud cleaner GNZJ703-1S8N. This unit is combination of 1ea shaker, 1ea desander cones and 8ea desilter cones. Mud cleaner, Small footprint, and 2nd and 3nd phase treatment, to remove most solids above 30microns.

3) 1ea mud hopper, the mud hopper is necessary to mix the chemicals and adjust the gravity of drilling fluids.

4) 3ea centrifugal pump. 2ea centrifugal pump is used for feeding the mud cleaner, desander cones and desilter cones. 1ea centrifugal pump working with mud hopper, to give power for mixing the chemicals.

5) 1ea mud tank to support all above mentioned solids control equipment. The mud tank is same size with container, can be locked on trailer, guarantee on the safety during transportation.

6) 1ea submersible slurry pump, this is option. The client can buy from GN the slurry pump for feeding the mud system, and even the hose to connect the slurry pump to the mud system.

The end.

GN mud system is composed of 4 phase mud treatment equipment & mud tanks, including auxiliary equipment, like mud agitator, mud gun, mud hopper etc.  Recently, we have one client from Middle East who need to buy 2 sets of mud system for the water well drilling rigs.  As the water well will be drilled to 1000m to 1500m depth, we recommend complete mud system with 4 phase mud separation equipment.

The required two sets mud system are the same, each mud system equipped with below items:

1) Shale shaker

4 panel shale shaker with composite material shaker screen. The shaker screen is equivalent to Swaco Mongoose.

4 panel shale shaker with longer shaker deck, the separation performance of the drilling mud will be much better than 2 panel or 3 panel shale shaker.

Some client may have large quantity shaker screen stock for King cobra shaker, we can customize proper size shale shaker to meet the requirement.

2) Mud cleaner

4 panel mud cleaner, with 4 panel shale shaker & 1ea desander cyclones & 8ea desilter cyclones.

The mud cleaner with below advantages:

  • Desander & Desilter & Shale Shaker 3 in one unit mud cleaner for compact footprint.
  • Polyurethane Material hydrocyclone for long life
  • Removable hydrocyclone assembly for adjust to be a shale shaker.
  • Patent  shaker deck angle adjustable while working, mechanical deck angle adjustment with reliable performance.
  • Patent tighten rubber sealing for mud cleaner shaker deck and screen for fine screen

3) 40ft container size mud tank

The mud tank is same size to 40ft container with container locking port and lifting pad eyes.  The mud tank also equipped with 1ea mud agitator in the 3rd compartment of the clean mud, and one mud hopper with one centrifugal pump is installed on the skid of the mud tank to mixing chemicals.

In order to treat the drilling cuttings, operators need to check out way to transfer the drilling cuttings to the treatment gear like high G dry skin shale shaker and vertical H cuttings dryer. The most popular opportunity for transfer drilling cuttings is a screw conveyors (Auger Conveyor), and the drilling cuttings send pump.

Part 1) Mess Conveyor for Drilling cuttings transfer
Screw conveyor can also be called Auger Conveyor, it truly is one of the most popular equipment to get transfer drilling cuttings. Advantages for the Auger conveyor will be the simple design, and easy operations, as well as a long length with regard to picking up the cuttings dismissed from the shale shakers or even mud cleaners on the drilling rig mud tanks. Often the disadvantages are that, it can be hard to layout for move from one equipment to the other, for the long distance. Since the conveyor cannot lay at qualification over 45 degree. Which is not good to transfer drilling cuttings with high moisture.

Component 2) Vacuum Pump or even  shear Pump for drilling cuttings transfer.
The vacuum cleaner pump or solids pump are used to transfer drilling cuttings. The big advantages are long-distance transfer with easy configuration, and it can be use to get transfer high moisture drilling cuttings. The vacuum pump or solids pump are generally driven by air, making it safe to operate in threats areas to be explosion explanation. The disadvantage are the power usage for creating air, and never suitable to pick up drilling cuttings from different equipment much like the shale shakers, mud cleaners and decanter centrifuge  on the mud tank.

So most of the cases, workers will combine the drilling cuttings screw conveyor plus the solids pump together to help transfer drilling cuttings for the treatment equipment.

GN Solids Control is able to provide you the actual screw conveyor and drilling cuttings transfer pump for any drilling waste management operations. Furthermore high G drying shaker and vertical cuttings electric drying machine are available from GN manufacturing in stock.

Last week, after months of hard work of all GN staff, 70 containers of solids control equipments from GN Solids Control sailed to Middle East. This is a land mark of not only GN’s company memorandum, but also a breakthrough of China branded solids control equipments and drilling waste management equipment. This order is working for oil service in middle east and work in tough conditions of temperature above 55 degrees centigrade.

Those equipments are of high quality material and per clients’ requests, they are of ATEX Zone 1 standard and with DNV lifting.

GN VFD controlled decanter centrifuges are always popular among the clients and countries in middle east and other high temperature conditions.

For the centrifuge main body, the high configuration GNLW series decanter centrifuges share the same features like:

  1. best bowl material SS2205 by centrifugal casting and such is the highest standard material for oil and gas decanter centrifuges. Many European and USA brands use this kind of material for bowl material.
  2. SKF bearings for stable performance and longer service life. And during transportation, GN has special and gentle solutions for protecting the bearings from being damaged on the rough road.
  3. tungsten carbide tiles for impeller protection and special ceramic material for solids discharge ports.

And many other features are applied.

About the VFD control panel, GN has both flame proof VFD control panel and positive pressurized VFD control panel with PLC smart touching screen. The positive pressurized control panel has the self cooling system, and it is more suitable than the flame proof ones in high temperature condition. All the electric components are of international famous brands like Siemens, Schneider and ABB. For this order, because they are of ATEX Ex, some brands and standards are even higher than usual.
