GN CBM Drilling Mud System

GN Solids Control is a worldwide famous
brand of mud solids control system, drilling waste management system, as well
as replacement shaker screens.

This week, GN Solids Control China factory
finished a mud system for a domestic project. It is a 4-tank mud system for
750hp drilling rigs.

1) The 4 mud tanks of the 750hp rig mud
system are the same size with 40ft container. And the tanks are equipped with
3-runner oilfield skid. The oilfield skid is with 250mm at each tank ends. It makes
the tanks easy to movement at jobsites.

2) GN Solids Control equips 2 sets Solids control
linear motion shale shaker separator for the system. The system is equipped
with 2 each 3-panel shale shaker, model GNZS703E. It is the most popular shaker
models for oil and gas mud system from GN Solids Control.

3) In this system, the clients choose 1
desander separator and a desiler separator.

The desander model is GNZJ752-2S. It is
equipped with 2 ea 10’’ desander cone. Each 10’’ desander cone is with max. 120
m3/h (528GPM) handling capacity.

The desilter cone model is GNZJ752-12N. It
is equipped with 12 ea 4’’ desilter cone. Each 4’’ desilter cone is with max.
20 m3/h (88GPM) handling capacity. For totally 12 ea 4’’ desilter cone, the
desilter handling capacity can reach to 240m3/h (1056GPM).    

4) The 4-tank mud system is equipped with a
middle speed decanter centrifuge to recovery the barite and reduces the mud
weight. The centrifuge model is GNLW452. It is a most cost-effective big bowl
decanter centrifuge widely used in solids control mud systems for oil rigs.

5) And there are many mud agitators, mud
guns, lights, and pumps for the system.

6)
This clients choose a separate jet mud mixing system. The jet mud mixing hopper
and mixing pump as well as control panel are all mounted in a separate oil field
design skid. It is easy to move it and work to different mud tank systems.

As
more and more authorities issued more and more strict rules on the envornment
protection, drilling
waste management equipment gets more and more necessary at drilling rig
site, especially in oil and gas drilling rig website. As the drilling fluids
material various kind of chemicals, in case discharged directly. it will have
really bad pollution to the atmosphere.
GN Solids Control most recent design drilling waste management equipment drill
cuttings renforcement unit are welcomed in jobsite.
1) The drill down cuttings solidification unit may be used to treat drilling
cuttings released from the high G drying out shaker. When the cuttings through
solids control shale
shaker, desander,
desilter treated by higher G drying shaker, the actual fluids will go to drying
out shaker catch tank for more treatment, the solids through high G drying
shaker can be treated by drill cuttings solidification unit.

2) The actual drill cuttings solidification device can be used to treat
drilling cuttings discharged from decanter centrifuge. The liquid phase is drilling
to be covered by further treatment, such as dewatering unit. while the solids
phase can be treated by drill down cuttings solidification unit.

3) The solids discharged through vertical
cuttings dryer could be further treated by drill down cuttings
solidification unit. It may reduce the water content within the waste.
Many clients may question, what is the water content following the drillings
treated by drill down cuttings solidification unit? It can be hard to see what
the water content material is. As it is flexiable. It really is controlled by
the operators. If you want to the actual cuttings dryer, you include more
chemicals, if you do not require very dryer, you can slow up the quality of
chemical.
Top features of GN latest design drill down cuttings solidification unit
1) Small footprint with high effectiveness of GN latest style drill cuttings
solidification device.
2) Automatically control associated with GN latest design drill down cuttings
solidification unit.
3) All the screw conveyers associated with GN latest design drill down cuttings
solidification unit tend to be variable speed control.

The drilling mud decanter centrifuge driven
by VFD will give many benefits to the clients. The adjustable bowl speed and differential
speed allows the operators to set the right G force and solids pushing speed
according to the drilling mud conditions.

To design the VFD Control Panel, the
contractor needs the power supply specifications. Normally it is 460V/60HZ for
USA standard or 380V/50HZ for Europe and China standard. Than the pulley size
of the motor and bowl side will decide the bowl driving speed at different
frequency. After confirming the bowl speed formula, the contractor needs the
formula for calculation of the differential speed. For GN Decanter centrifuge,
the Sun-Wheel gear box ration is 57:1. So the differential speed will be the
bowl speed minus the gearbox input speed and divided by 57.

For the VFD Control panel, there is
different explosion proof standard. In China, it is CN Explosion proof which is
close to IEC Ex standard. In Europe, it is ATEX Explosion proof. And in North
America, the explosion proof standard is UL for USA, and CSA for Canada.

GN Pressurized VFD Decanter Centrifuge control
panel is specially design for Zone 1 or Zone 2 standard with ABB VFD and
stainless steel cabinet. The PLC smart control allows the user to operate the
drilling mud decanter centrifuge by HMI screen.

GN VFD decanter centrifuge has been
exported to over 30 countries and regions, GN Solids Control VFD decanter
centrifuge is available in different sizes including: GNLW223C-VFD (9inch)
bowl, GNLW363C-VFD(14inch bowl), GNLW453C-VFD (18inch bowl), and the big bowl
big volume centrifuge with 22inch bowl and model is GNLW553C-VFD.

GNSB centrifuge pump manufactured by GN Solids
America LLC is the mud feeding machinery for solid control equipment in
drilling mud system.

Pump installation

Pump installation location should be near to
the source and purposely to shorten the length of the suction period and
prevent the suction loss. Pump installed base should be leveled, firm and secured
in order to avoid vibration during operation.

 Coupling installation

The pump and motor for a long use life depends
on the elastic coupling. Available steel straightedge by coupling the up and
down or so, with the view straightedge and coupling the garden all parties
should contact closely. Namely coupling outside garden parties should be in a
straight line to make sure that the motor shaft and pump shaft coaxial angle.

 Entrance pipeline installation

Entrance piping shall be in accordance with
the pump inlet matching.

Suction piping not allowed to install throttle
valve, but can be installed normally open valve to reduce fluid flow disorder. To
avoid suction people line produced in steam bubble, the pumping source and
between pump from high to low gradually transition. If users need to pump in
use suction conditions, use vacuum pump or bottom valve pilot.

Pump at the entrance line must be flat; the
length of at least two times the diameter of the inlet line.

Exit line

In order to facilitate pump maintenance, the exit
pipeline should be installed normally with open valve.

All line (including population line) must have
their own support.

When work condition is unknown or unstable,
export in pipeline must be installed throttle valve in order to ensure the pump
in the design point operation.

When the pump discharge and pressure equipment
connected, the throttle valve and pump must install a check valve to prevent
the liquid reflux, otherwise, the return fluid can lead to damage
