GN CBM Drilling Mud System

Solids control system play a very important role in oil and gas drilling. It cleans the
drilling mud which includes many wasted cuttings, and recollects the mud for
recycling usage. Drilling cutting discharged from the solids control equipment is
always also wet with oil or water content. If disposed directly to the ground,
the wet drilling cuttings will contaminate the environment seriously. With more
and more strict regulations on Waste Discharge, it is now allowed to directly
pour the wet drilling cutting on the ground, and the liquid content is requited
to below OOC 5%, then can be discharge.

GN vertical
cutting dryer provides the proper solution to
solve this problem. Solids discharged from shale shaker and desander, desilter
or the mud cleaner will be directly delivered to the vertical cutting dryer
instead of being disposed through screw conveyor. The vertical cutting dryer
will throw the liquid out in high centrifuge force; solids will be preventing
form throwing out by a stainless steel screen. Thus solids and liquids are
separated. Solids will fall into a collecting box from the bottom opening;
liquid will flow into a mud tank from which it will be pumped into a high speed
decanter centrifuge for further treatment.

GN vertical cutting dryer now is working
for a Shell project in Sichuan, China. Also, one set of GN vertical cutting
dryer is used in Europe. Also, 4 sets are for Baker Hughes project in Russian.
With more and more strict environmental regulations, drilling waste must be
treated if wanted to be disposed. Besides fixed speed vertical cutting dryer,
GN also provides VFD control for option. It control the rotating speed of
vertical cutting dryer, and also the flushing pump which is used to flush the
liquid to ensure the liquid flow smoothly.

Being an expert of solids control equipment and drilling waste management equipment, Hebei GN Solids Control Co., Ltd is focused on designing, manufacturing and selling decanter centrifuge. Decanter centrifuge not just can be used as solids control equipment serving as the final stage to split up particle which having a diameter under 10 microns, more specific, two to five microns, but additionally can be used to purify mud released from vertical cutting dryer inside a drilling waste management system.

 GN Solids Control presently has a set of NEW decanter centrifuge GNLW454G on purchase with 30% discount. Just only one is on discount, and that one has been produced and examined, and today inside a ready station for delivery to around the globe. The primary parameters of the new decanter centrifuge shows up blow.

 It features a bowl size 18inches (450mm) having a draw ratio about 3.7 to at least one, it bowls length being 67 inches (1720mm). The bowl speed is 2200 Revolutions per minute or 2500 Revolutions per minute based on different pulley, creating an optimum G pressure 1573G.Treating capacity of the new decanter centrifuge is 60 cubic meters each hour. And also the primary motor is 45kw; the rear drive motor is 15kw.

 Why GN makes this type of discount for this new decanter centrifuge? The essential reason is the fact that GN has stopped producing GNLW454G decanter centrifuge, and changed it with GNLW454-VFD series decanter centrifuge, which have a similar bowl diameter, but have shorter bowl length and speed, plus they creates a high G pressure. While there no necessity to doubt the post sales service when you purchased it, since the core technology is identical. And also the putting on spares will also be same, so that you can still purchase add-on spares part from GN solids control.  Just one is on sales, be quick!

The function and principle of Oil water filter

Oil water filter, it is mainly used to treat the contaminated oil, such as cooling system oil in drilling waste vertical cuttings dryer. Its function is filtration, purification, recovery or enhance the attributes of oil itself. The treatment process is including oil cleanliness, moisture content, gas content, acid value, viscosity, flash point, the insulation strength, color and so on. Oil water filter can effectively remove impurities in oil to guarantee safe operation of the equipment.

Application scope of Oil water filter

Oil water filter is mainly used in mining industry, metallurgy, petroleum field (drilling mud cleaning system), railway, machinery, chemical, textile, cement, power, instrumentation and other industries. It has big effect on the purification and recovery of variety of industry waste lubrication oil. Oil water filter can extend extend the maintenance cycle and service life of equipment, and reduce the production cost.

Furthermore, oil water filter can effectively remove oil pollutants such as: water, water soluble acid, alkali and mechanical impurities, improve the kinematic viscosity, flash point of oil, emulsification. To make oil quickly returned to the desired properties, close to or reach the national standard of the corresponding new oil.

Oil water filter for liquid mud plant base oil tank

Oil base mud is a normal kind of drilling mud for deeper oil and gas drilling. Diesel oil is used as base oil. Oil water filter is used before based oil tank, after treatment, the oil will be transferred to base oil tank through oil pump.

Beside oil water filter, there are other equipment are necessary for liquid mud plant

1) Mud agitator: it is equipped in each tank compartment to enable the mud moveable all the time, to avoid it from settle down.

2) Mud mixing system: for continue mud prepare

3) Huge capacity mud tanks

4) Electrical control system and lighting system for the whole system

5) Rain shade to protect the whole system from strong sunshine or rain.
