drilling fluids

GN solids control China headquarter has shipped 1
units of solids control equipments for 1500HP oil drilling rig to Russia. Our
best sold equipments in Russia market is including shale shaker, decanter centrifuge,
centrifugal pumps, mud agitators etc solids control equipments and decanter
centrifuge, vertical cuttings dryer package etc drilling waste management
. Although the world market is very slow because of the falling oil
price, because of good quality, advanced technology, user friendly design and
best service, GN solids control also sell very well in the market, the buyers
are looking for competitive price compared with US brand solids control
equipments but good quality, as the earliest and best exporter in China for
solids control equipments, GN solids control is their best choice.

The solids control equipments shipped to Russia

4 units of 4-panel screen shale shaker: GNZS594E-HB,
it is also the best sold model in America market for oil industry application.
The shaker screen size is 585x1165x40mm, If you have stocked shaker screens for
this size, GN shale shaker can help you to reduce the inventory.

2 unit of GNLW363CG decanter centrifuge with
3200rpm, which is the normal working speed for solids control industry and
drilling waste management, but the max speed is 3900rpm when it is specially
required to separate fine solids smaller than 2 microns. We also provide
variable speed decanter centrifuge for option, low speed for barite recovery,
and high speed for separation of fine solids and keep the drilling fluids clean
& balance.

20 units of centrifugal pumps completed with motor,
control panel, skid, coupling and pump head. The installation dimension of GN
centrifugal pumps are equivalent with famous brand centrifugal pumps, and most
of the spare parts are replaceable, for example, mechanical seal, pump house,impellers,

Welcome to contact with GN solids control for your
potential requirement in 2016.

GN decanter
can be applied to both oil based mud and invert drilling fluids, and
water based drilling fluids and Synthetic Based mud.

drilling fluids are generally used where drilling problems not easily handled
by water-based fluids are expected, or in situations where the invert drilling
fluid is more economical. The major advantage offered by invert fluids is
increased borehole stability.

To Serve our
clients better, GN solids control keep our main equipments in stock , including
different sizes decanter centrifuge, vertical cuttings dryer, hi-G drying
shaker, shale shaker, mud cleaner, economy mud cleaning system, etc.

GN vertical
cuttings dryer can be used for both water based mud and oil based mud, we are
the first China solids control equipments manufacturer who firstly designed
such multi functional vertical cuttings dryer and firstly field proved for
drilling waste management. Our unique air knife design can avoid the screen
basket blocking for water based drilling cuttings.

GN designed solids removal unit for mining drilling is a compact designed unit to remove the solids from the drilling fluids, the semi-dry solids are disposal by the truck and the fluids is drained off to the river or re-use for drilling.This unit can be designed for both skid mounted or trailer mounted portable for easy transportation from one rig site to another. GN 150L/min solids removal unit for mining including the equipments below:

1 GNLW223VFD high speed decanter centrifuge, with the smallest model 9 inch bowl diameter, the max bowl speed can reach 3800rpm or 4200rpm.

2 GNZS752E-DM 2-panel shale shaker with top hole section to remove the big solids and less the solids content before feeding to the decanter centrifuge

3 silenced generator 38KVA with Cummins engine, the clients can source the spare parts locally

4 mixing hopper, mixing pump, VFD control panel, shale shaker, decanter centriuge, silenced generator, electric control panel are all mounted on one skid for convenient move

5 General treating capacity of this solids removal unit is 150L/min

6 Mud tank volume is totally 4000L, to storage enough clean drilling fluids for reuse

Benefits by using GN solids removal unit:

1 Environmental friendly, sump free operation

2 Ruduce water consumption

3 Cost savings, including reduce drilling fluids consumption, reduce site set-up and remediation costs, protect the diamond core drilling bits so reduce the down-hole drilling tools cost,etc.

4 Semi-dry solids can be moved directly by truck, save the cost of solids disposal

5 Complete dimension of the whole solids removal unit is same with standard 20ft container, with standard trailer for shipment, need small space to set-up

GN designed customized solids removal unit to meet different requirement of our clients in mining industry, GNLW223 series decanter centrifuge have been widely used to separate fine solids from the drilling fluids. Pls contact GN solids control or GN solids America for more information.

Decanter centrifuge can be used for various industries including food, chemical, paper, waste management, mining, oil recovery, oil & gas drilling, GN solids control brand decanter centrifuge is mainly used for drilling fluids industry, including solids control and drill cuttings waste management.

GN produced drilling fluids decanter centrifuge including high speed decanter centrifuge, low speed decanter centrifuge, middle speed decanter centrifuge and variable speed decanter centrifuge. For high gravity drilling mud, we recommend middle speed centrifuge. For low gravity drilling mud, we recommend high speed decanter centrifuge GNLW363G with 3200rpm rotary speed. If you bought our variable speed decanter centrifuge GNLW363VFD, you can adjust the speed by the PLC control panel. If you bought our rated speed decanter centrifuge, we can provide 3 sets of extra pulleys to change the high speed to middle speed or low speed decanter centrifuge.

For better performance of GN decanter centrifuge, you should pay attention to the following points:

1 Lubrication according to the lubrication chart we recommend, especially for the 2 bearing blocks, gear box, hydro-coupling.

2 Cleaning and flushing: the centrifuge bowl inside and outside should be flushing after every time start, to avoid the solids accumulated around the solids discharge port.

3 Proper feeding capacity to ensure there will not be too much solids accumulation.

4 Use proper speed for different drilling fluids, change the speed by change pulleys or by manually adjustment in the PLC control panel

5 Replace the spare parts in time once any wear parts are damaged

6 separate the big solids by shaker screens or hydrocyclones before feeding them to the decanter centrifuge

7 GN recommend Nemo screw pump as the feeding pump of our decanter centrifuge

8 Proper transportation and storage: During transportation, the safety guard should be tighten; and during operation, it should be released.
