Closed Loop Drilling Mud Solids Control System Minimize the Waste on Drilling Liquids

nowadays the drilling liquids is broadlyutilized in drilling projects and underneath the strict regulation on atmosphere protection, the ways to minimize the release of environment hazardous waste solids and maximum the drilling liquids recovery must be the mainstream subject in the industry.

The using of mud tank to keep the drilling liquids returning in the drill well continues to be broadly identified and accepted by all of the drilling companies. Without digging a mud pit on the floor help reduce the pollution towards the soil. Specifically for some limited job area, the mud tank will be the preferred option for drilling liquids. The using of the several types of the solids control equipment highly accelerates the separation of solids in drilling liquids.

The closed loop drilling mud solids control system, if complete configuration, consists 2 parts. Drilling mud is used in solids control and waste drilling cuttings treatment. The objective of this 2 parts is similar for minimize the release of environment hazardous waste solids and maximum the drilling liquids recovery.

For solids control, after discharged rough the shale shaker, desander, desilter, the decanter centrifuge. The ultra fine solids contaminants could be removed out of the drilling mud, after that the drilling mud can be reused.

The drilling waste cuttings treatment part is performed to recovery whenever possible the drilling liquids making the cuttings dry enough for simple transportation to help environment friendly through treatment. The cuttings out of the solids control shale shaker and desander, desilter could be moved to drying equipment first. The drying equipment could be different due to that the water based mud or oil based mud can be used. A higher G drying shaker is the best for water based drilling mud cuttings. The Verti G cuttings dryer is always utilized for drying the water based and oil based cuttings.

GN Decanter Centrifuge to Africa Customer

As an expert in solids control equipment andsystem, GN solids control manufactures and exports a complete set of
solids control equipment and system including shale shaker, desander, and
desilter and decanter centrifuge. At the beginning of this year, GN solids
control received a repeated order that a customer with which GN has cooperated
for more than three years, and this customer is satisfied with GN decanter
centrifuge, high quality with competitive price. And this time, GN has
updated its design for more stable and better performance with several update.

The updated decanter centrifuges still has
the below advantages of the last edition.

1. The
cylindrical and conical section of the bowl is made from duplex stainless steel
2205 which is better than stainless steel 316L. Stainless steel 316 is always
adopted by China’s other solids control company; even stainless steel 304 is
adopted.

2. The bowl is manufactured by centrifugal cast which means that the bowl has a
better balance. Only the decanter centrifuges pass the balance test, they can
be delivered.

3. Tungsten
carbide tile is attached on the screws to protect the screw from wear, and when
the tungsten carbide tiles is worn out, it is easy and convenient to replace
with re-doing the balance test.

For the updated decanter centrifuge, there
are more advantages:

1. Solids
discharge cover is added above the solids discharge port to prevent the solids
discharged to the inner cover of bowl.

2. Special
ceramic mud distribution port on the screw will extend the decanter centrifuge’s
service life.

GN solids have made it policy that GN
solids control will keep to update its product for better service and provide
better services. It is a wonderful start in 2015 with the big order from a customer,
the first batch has been delivered, and the second will be delivered soon.

Hydrocyclone Installation

The mud that contain drilling cuttingreach the ground surface, the process of filtering begin start with shale shaker that contain the shale shaker screen indifferent mesh. The whole process also
depends on the ratio of liquid and solids in the mud as well. While treatment through shale shaker screen is necessary, it is
far from enough and that is what hydrocyclone come to use to take the
filtration to next level.

Hydrocyclone filter less aggravate
solids that is size 15-20um, after the shale shaker. It is install convenient to flow bottom and
also convenient for maintenance and monitoring the filtration of the drilling
mud. The large (10 inch) diameter of
hydrocyclone should be install on upstream and the small (4 inch) diameter of
hydrocyclone should be install follow by large ones. The hydrocyclone need to pair with drilling fluid tank and centrifugal pump.

GN Solids
Control’s desander have installation of 10 inch hydrocyclone
which contain between from 1 cone to 3 cones to meet the different filter
need. To take the filtration further, it
pair with shale shaker that is detachable for convenience in change machinery
to meet the project need and maintenance.
The 4 inch hydrocyclone is for GN Solids
Control’s desilter which contain between 8 cones to 16
cones. The structure of the desilter is
same as desander that pair with shale shaker as well. The desander will remove the +40 microns of solids
and desilter will remove +20 microns of solids.
The shale shaker pair with desander and desilter is linear motion with
either 2 Martin or 2 OLI brand motor
which can produce adjustable G force up to 7.5 G of force. The panel of screen
are choice of 2, 3 and 4 depend the need of the drilling
project. All equipments construct in
explosion proof and meeting different region’s explosion proof standard.

The Introduction of Solids Control Models

Performance and excellence of drilling
solids control equipment is paramount to the introduction of solid control. Drilling solids control
system includes drilling fluid recycling tank, drilling fluid purification
equipment and drilling liquids mixing equipment of three parts. Drilling fluid
purification equipment mainly includes shaker, desander, desilter, degasser,
centrifugal machines, centrifugal pump (sand pump), shear pump, mud agitator and hopper etc. Under highly
restriction eco areas, you may also concern the drill cuttings recovery and
waste treatment plant.

Solid control equipment trends:

Drilling operator is expecting small
footprint, high quality, lengthy existence of apparatus and integrated high-speed decanter centrifuge, automatic recognition and
performance solid control system.

Worldwide Solids Control Company:

The majority of solids control equipment has
been in the United States including BRANDT, SWACO, and DERRICK along with other
companies. Their performance and quality are on top level on the planet.
They’re focusing on optimizing solid control system configuration and
efficiency of solid control system,

China Solid Control Company:

Lately, China solids control company has
accomplished a larger degree of development, mainly in the study from the
theory, for example shaker works, cyclone works, happen to be around the
world’s advanced level. The space between Chinese solid control company and US
solids control is lowering. Especially GN Solids Control is among worldwide
level solid control company which released their models to around the globe. GN
not just focuses on the standard solids control models for example shale
shaker, mud cleaner, mud agitator, centrifugal pump and hopper, but
additionally researches around the advanced waste management area including
vertical cutting dry and decanter centrifuge combination. However, GN follows
worldwide strict quality inspections on each and every model to make sure GN
worldwide quality and equipment safe issues.
