Solids Control System for Southeast Asia Customer with VFD Decanter Centrifuge

The particular solids control system might
remove the large solid contaminants in the drilling mud to minimize the solids
content to ensure that to protect the transferring send that used to transfer
the particular mud back the machine for reusing. GN just simply finished one
set mud solids control system along with VFD
decanter centrifuge intended for mining project in Southeast Asia.

This system is a two stages separation design product; the equipment
configuration is as beneath:
1 . Shale
shaker unit GNZS594E-HB used for coarse strong particle separation. This
shale shaker unit could also be utilized as a high G pressure drying shaker
with variable G force up to eight. 4-panel screen makes a more substantial area
for drying often the drilling mud.
2 . VFD design decanter centrifuge system used for fine solids separating. The
first one unit centrifuge operates at a middle speed to eliminate most of the
solids to reduce often the gravity. The following second device VFD control
centrifuge might run at a high speed to get rid of the ultra fine solid waste
to make the drilling mud clean.
3. Screw pump prepared to transfer the dirt to the centrifuge. Horizontally set
up at the flank of the reservoir, it helps to tank leading more space for
operation mobility.
4. Mud cleaner reservoir used as sand pitfall and active mud hard drive.
This system is to remove the sound particles in the drilling soil to make the
drilling fluids using again. After the solids being taken off, the fluids could
be piped back for reuse as well as the pump would be also guarded as there are
less solids dust.
Mud solids control strategy is
very common product and alternative that GN provides. For this reason, GN could
provide parting system used for oil going, no dig drilling task and some other
industrial sturdy and liquid phase separating. For more information, welcome

Most Efficient Equipment Used for Solids Control & Waste Management

As first API certified solids control
manufacturer in China, GN Solids Control has provided to more than 60 countries
and regions with its cost effective products, covering all related main
equipment of solids control and waste
management line for oil and gas drilling

The main principle of the
solids control systems is physical separation, using the physical
characters of different media, the solids control equipment separate as much
solids from the liquid. Right now, in other industries besides the oil and gas
drilling, such functional equipments are also chosen by the end users, to make
their work more efficient and easier

Physical Functions of solids control
equipment:

Since the most important solids control
equipments are respectively shale
shaker and decanter centrifuge, we talk about only these 2. Now in many oil
and gas drilling jobsite, the end users choose to use more shakers and
centrifuges instead of former hydrocyclones.

1. shale shaker. Shale shaker is the most
efficient equipment in solids control process, because it uses less energy
while separates the most solids out of the liquid by using the different size
of the solids and by means of different size mesh on the shaker and a couple of
vibration motors. The disadvantage is that the shaker could not separate very
fine particles, and its separation work is a bit draft. GN has 3 nos screen
shale shaker and 4 nos screen shale shaker for option with model GNZS703E and
GNZS594E.

2. decanter
centrifuge is a high speed rotation machine, mostly horizontal. It has a
high speed rotating bowl and inside bowl there is an impeller. During the
rotating, the centrifugal forces on different material are not same, that
causes the liquid phase continuously flows out of the bowl while the solids
particles are slashed on the bowl inside wall and pushed out of the centrifuge solids
discharge ports. The decanter centrifuge a gentle and precise, more costly than
shale shaker, not only the cost of itself, but also the consumption of electric
power. But it is ideal solution for separating out the fine and extra fine
particles. GN centrifuge family covers all common sizes of decanter centrifuges
from 9 inch bowl diameter to 22 inch bowl diameter, among those centrifuges,
GNLW363 with 14 inch bowl is the most popular model

Predecessor Shaker in Direct Field Comparison

The brand new generation Gn Professional shaker was designed to function both in the capability and Efficiency modes of operation. The Efficiency mode is really a Progressive Ellipticalmotion that creates 6.5 G, as the Capacity mode is really a Balanced Elliptical (BE) motion creating 7.5 G. An immediate comparison by having an earlier generation M-I SWACO shaker was carried out to ensure ale the Gn Professional shaker to supply enhanced performance to satisfy the ever demanding needs of today’s drilling procedures. GN recognized three critical criteria to evaluate overall desander performance: flow capacity, clippings discard rate, and clippings dryness.

A rig in Oklahoma was selected for that mind-to-mind comparison. In Feb 2011, the Gn Professional was installed near the control shaker, using the two linked to a manifold that will carry 9.92 lb/woman oil-based drilling fluid evenly to both models.

Three objectives were layed out using the subsequent performance data to become taken throughout the drilling of the well. Throughout the operation, the Gn Professional was operated within the PE mode as the control shaker was operated within the BE mode, underneath the same drilling conditions. Real-time comparative data on flow capacity, clippings discard rate and clippings dryness were collected from both Gn Professional and also the control shaker throughout the drilling operation.

Test is a result of the well confirmed the highest performance from the Gn Professional drilling waste management. To keep comparative control, both shakers were installed with similar parameters: deck position (0°), screen mesh (API 140), and fluid pond coverage (75% screen coverage). Throughout the 8 ½ in. section in a depth of three,300 foot (1,006 m) by having an ROP of 100 foot/hr (30.4 m/hr), the Gn Professional processed an optimum flow rate of 410 GPM, or 70% from the overall circulating flow rate. Meanwhile, the control shaker processed an optimum flow rate of 293 GPM, amounting to simply 50% from the overall circulating rate. In comparison towards the control shaker, the Gn Professional, while running within the Efficiency mode, averaged a general 28% rise in maximum flow rate, but 20% around the well volume.

Within the 8 ? in. section, the utmost clippings discard rate measured for that Gn Professional shaker was 3,484 lb/hr (1,580 kg/hr) in comparison towards the control shaker’s maximum clippings discard rate of two,400 lb/hr. Overall, the Gn Professional shipped a 33% rise in clippings discard in comparison towards the control shaker while keeping exactly the same clippings dryness.

Even though the Gn Professional shaker displayed the capacity to deal with a greater fluid capacity and process a greater amount of clippings, the shaker could attain the same degree of clippings dryness. The Gn Professional and also the control shaker both shipped average clippings dryness of 68% “dry” and 32% “wet.” Click here to enter the GN next page, where there must be something you want.
