GN Centrifugal Pump to Deliver Drilling Fluids

GN solids control distinguishes
itself from other China’s manufacturers by its cost-effective product with
competitive price to USA/EUEOPE brand but with fine and stable performance.
Beside supplying solids control equipments such as shale shaker, desander, desilter, mud cleaner, and decanter centrifuge, GN solids
control also supplies centrifugal pumps to deliver drilling fluid.

With stable performance and long service
life, GN SB series centrifugal pump is designed to deliver abrasive, viscous,
corrosive media, especially drilling fluids and industrial slurry. The pump can
handle large volume flow up to 320m3/h, withstand high temperature, and
remarkably save energy, but is easy to maintain. Currently, GN centrifugal
pumps are operating widely both on onland and offshore drilling rigs around the
world. Taking drilling fluids’ condition into consideration, we are committed
to offer the best solution to our customers.

The housing of GN centrifugal pump is thicker,
heavier and solider because of the special strength when compared with
conventional pumps, thus enjoying a more durable and longer service life.

The annular flow channel inside the housing
will eliminate turbulence and cavitation, also reduce radial load on the
bearing. The housing gasket is recessed to prevent fluids from leaving the
impeller. In oil and gas field, centrifugal pumps are mainly used as feeding
pumps to desander, desilter or mud cleaner, mud mixing pump, and supercharging
pump to mud pump. Regarding to the first application, the liquids discharged
from shale shaker will be delivered to the desander, desilter or mud cleaner by
the centrifugal pump, always horizontally installed on the skid of mud tanks.
To the second, the chemical will be added when the centrifugal pump discharges
the fluids out, usually fixed below the mud mixing hopper, also on the skid of
tank. For the third, the centrifugal pump will be used as supercharging pump
for mud pumps.

The 5 steps purify drilling mud

Drilling mud purifications
is the basic to insure the function of drilling bit works properly and safely
for both oil rig equipments and many operators working around the clock in the
drilling field. Needless to say, it is a
very costly operation if one or many steps of drilling operation go wrong, It
will leads operation cost of drilling rig go double in very short amount of
time that leads to increases of operation cost and late leads to increase the
production cost of oil.

The first level of purification

The mud feed in the shale shaker. The allocation drilling fluid
enter into the bottom of the drilling well under the foundation of the drilling pump
and carry drilling debris return the ground,
through the feeding enter into the shale shaker, the larger solid debris in drilling fluid are filtered through shale
shaker screen.

The second level of purification

When drilling fluid have debris and also contain gas, The use of vacuum degasser remove the gas which in the
drilling fluid and can recover the density of drilling fluid, calm the drilling fluid viscosity.

The third level
of purification

The drilling fluid is disposed by two level purification enter into the desander. Through the desander feed into the liquid pump, the harmful sold phase which the diameter
is above 40-60um is separated in desander.

The fourth level of purification

The drilling fluid is disposed by the three level purification enter into the desilter
through the desilter feed into the liquid pump, the harmful sold phase which the diameter is above
15-40um is separated in desilter

The fifth level of purification

The drilling is disposed by the four level purification enter into the decanter centrifuge through the centrifugal feed liquid pump, the
small harmful sold phase particles are separated in decanter centrifuge

GN Presentation

Hebei GN Solids Control Limited Company is a China & USA based
manufacturer of complete line solids control equipment; waste management equipment and shaker screens. Though
established in 2007, GN solids control has been growing fast and stably:

3. Firstly set up USA based branch with warehouse
among all China’s solids control manufacturers

4. Partners in
Australia, the Middle East, and the Latin America have been developed.

5. A GN brand
achieved with the target to medium-high end customers;

Mainly, GN product line includes:

Solids control equipment-shale shaker, vacuum degasser, desander,
desilter, mud cleaner, and decanter centrifuge, also mixing device such as mud
hopper, agitator and mud gun;

Auxiliary pumps, safety device-mud gas separator and flare
igniter.

Waste management equipment- high G shaker, vertical cutting dryer, decanter
centrifuges;

Shaker screens with a specialized facility to produce, also replaceable screens for all famous brand shale shakers.
Mainly applied in Mining and industrial field, oil and gas drilling; HDD or CBM
drilling;

Always, people may not trust blank words on the high quality, so
GN powerful facility will say; GN professional certificates will say.

GN owns a 65000 square meters manufacturing facility in a
well-developed industrial area, near to Beijing, 40km to Beijing International
Airport. After the presentation, we’ll show your around all workshops one by
one: firstly warehouse, workshop 1 for raw material processing; workshop 2
assembly, workshop 3 for centrifuge and vertical cutting dryer where CNC
machines are used to control quality and increase productivity, workshop 4 for
painting with ball blasting machine and auto powder coating line.

Wide yard to place big project such as solids control system and
over 30 sets decanter centrifuges.

GN America Branch with warehouse;

Also specialized factory in Asia largest wire and mesh city to
produce screens for GN shaker, also for famous brand shakers such as Derrick,
MI-Swaco.

New factory especially for centrifuges is close to be finished,
ready for operation one or two month later.

GN is the first API certified solids control manufacture in China,
also certified by ISO 9001:2008, DNV CE. Russia TR&TC, HSE for safe
production; also ATEX IECEX for electric control panels.

GN Solids Control dispatching equipment to overseas market

Recently, GN Solids Control just dispatch one set
solids control equipment to
overseas market, Middle East country. The end user is Middle East horizontal
directional drilling contractor with over 10 sets HDD drilling rigs. After they
come to Beijing and inspection GN factory, they releaser order for one batch of
equipment. The solids control equipment includes:

6 sets centrifugal pump for mixing/ transferring
drilling mud. Electrical control panel with necessary cables is also included.

2 sets shale shaker for drilling mud first phase
separation. The shaker is GN popular 3 panel shaker GNZS703.

2 sets mud cleaner for drilling mud second and
third phase separation. The mud cleaner with 2pcs desander cones and 12pcs
desilter cones is working well at customer’s drilling rig site now. Down deck
shaker is same as GNZS703.

2 pcs mud hopper with size about 1100 X 680 size.

8 pcs mud agitator to
mount on mud tanks to agitating and suspending the drilling mud.

8 pcs mud gun work together with drilling mud
agitator.

4 pcs mud tanks similar size to 20ft container
for storage drilling mud. The customer already have some tanks for recycling the drilling mud.

After receive the solids control equipment, the

we can communicate with email & pictures. Generally, problem will be solved
very soon. For the new customer who just enter into HDD field, they may ask for
help from us for the first time rig up. GN Solids Control can offer solids
control equipment & solids control service training at same time.

Except for solids control equipment, GN can offer
drilling waste management equipment.
Like decanter centrifuge, vertical cuttings dryer, screw conveyors, hi g
dryers, thermal desorption unit, solidification unit etc, and the whole process

GN Horizontal decanter centrifuge system

This centrifuge system may includes
different parts from shale shaker, desander mud cleaner, desilter mud cleaner, decanter
centrifuge, all of them is the combination of 4 phase mud solids separation
system; big capacity mud tanks with mud agitators and mud guns is necessary for
all the mud system. This is necessary equipment for oil & gas drilling
rigs. Formerly, there are only US company can offer that, but now more and more
drilling companies, oil service companies, solids control service companies
come to China, come to GN Solids Control for factory inspections and place
orders.

GN Vertical cuttings centrifuge system

GN Vertical cuttings centrifuge system is
also called vertical cuttings dryer system. This name resource from the
function of the equipment, to dry the solids.
