Per experiences and calculated data, the drilling liquid occupies in any well drilling is between 4 percentage to 10 percentages, no matter in onshore drillings or offshore drillings. Considering its effects on the drilling operation performance, which occupies nearly 50 percentages, the drilling fluid is quite vital to the drilling.

GN Waste Management Equipment

That’s why, a professional drilling manager has to have a professional team for the drilling mud services, or find a qualified drilling fluid service company. In practice, drilling companies or drilling contractors always focus on drilling work, and employing a subcontractor for the solids control system. Each drilling rig has eight systems connected to each other, among which, the solids control system is comparably independent. An expertized drilling fluid company has the right personnel and suitable equipment, and more important, they know how to treat the fluid well.

A professional oil service companies provide following services:
1. Solids control equipment and services. The solids control systems help to treat the drilling fluid directly from the well mouth. It contains three or four phases for separation, including the shale shaker as the first phase, the desander cones as the second phase, the desilter cones as the third. Some include the decanter centrifuge as the forth one. In most solids control systems, there are mixing unit for adding more chemicals into the fluid when necessary.
2. Drilling cuttings waste management systems, in some countries, this part is also regarded as a part of solids control, because this is also for treating the solids from the drilling fluid. Those systems always contains the vertical cuttings dryer, the high G drying shaker and the decanter centrifuge.
3. Drilling fluid waste management, it is the further treatment for the drilling fluid. As the fluid has been used for a long time, this system uses some chemicals to flocculate the extra fine particles into larger ones before being separated out by a decanter centrifuge.
As one of the leading manufacturers of solids control and waste management, GN Solids Control has been providing lots of oil service companies in the world for all above mentioned systems and equipment. For more information or a formal quotation, welcome to contact GN directly.

Like one of the largest oil reserving countries in the world, also Iran was under sanction for many years, no one could ignore the power of IRAN, as the coming IRAN OIL SHOW is the first oil show after the releasing of the sanction, many companies are coming to this oil show including GN Solids Control.

GN Solids Control has brought to IRAN a GNLW363CG decanter centrifuge, and this centrifuge is also the most popular model among all the centrifuges GN produces.

Advantages of GNLW363CG Decanter centrifuge:

GNLW363CG decanter centrifuge is of the highest international standard.

  1. material used for the bowl of GNLW363CG decanter centrifuge is SS2205, and impeller protection, GN use tungsten carbide tiles for better protection and longer service life and also easy for maintenance.
  2. spare parts, like the bearings, GN use genuine SKF bearing for the longer service life and stable performance.
  3. protection belts during transportation, helps the bearing not to be damaged during long way transportation.

More details pls see GN website.

GN decanter centrifuges

Now, the new design and model of GNLW363D is coming, if you have time, welcome to contact GN Solids Control for a visit near Beijing, Capital of China.

 

Advantages of GN Solids Control:

  1. GN Solids Control is the first API certified solids control manufacturer in China.
  2. GN Solids Control’s products was exported to more than 60 countries and regions all over the world, the clients include many international huge companies.
  3. GN Solids Control’s products cover the complete line of solids control and waste management, including the drilling cuttings waste management, the dewatering system, the solidification unit and even the TDU.

4, GN’s products is not only used for oil and gas solids control but also the HDD, TBM, CBM, water well drilling and etc.

 

GN Solids Control’s booth in Iran Oil Show is Hall 38, booth Number 1734. Welcome to see GN centrifuge and talk with GN’s sales team there.

Or if you have to miss Iran Oil Show, you can also visit our booth in Moscow Oil Show, in OTC, or in Abu Dhabi in November.

Decanter centrifuge is one of the most important equipment in a complete solids control system and a waste management system not only for the drilling cuttings waste management but also the further treatment for the drilling mud. In some projects, the shale shakers with different API number shaker screens and the decanter centrifuges with different rotating speed, they can totally replace the desander and desilter cones. That’s why a professional decanter centrifuge and a efficient centrifuge feeding pump are very important to the drilling mud system.

According to the control panel, the decanter centrifuge could be divided into 2 kinds, the fixed speed one and the VFD controlled one. And the centrifuge feeding pumps are of different types also, some are suitable for both the fixed speed and VFD controlled panel.

  1. the centrifugal pumps are most widely used in oil and gas solids control systems, and in theory, it could be the centrifuge feeding pump also, just like it roles for feeding the desander cones and desilter cones and also like the mixing pump. But in fact, it is not so common as centrifuge feeding pump.
  2. the submersible slurry pump. In the solids control system, submersible slurry pump is the most common choice for feeding the centrifuge. Because it is vertically installed, it occupies small foot print on the limited tank surface. And comparing with mono pumps, the submersible slurry pump is less expensive and easy to maintain.
  3. screw pump, which is also called the mono pump is the most popular pump used for feeding the centrifuge especially in the waste management systems. GN recommend this screw pump for feeding the decanter centrifuge, and GNLW363CG-VFD decanter centrifuge, the 3 VFD controls include the VFD control for the screw pump.

If you need more information, welcome to contact GN sales or visit GN office.

Among all the decanter centrifuges used for solids control and waste management systems for oil and gas drilling, they could be divided into big bowl centrifuges, medium sized decanter centrifuges and baby centrifuges. Per bowl rotating speeds, they could be divided as middle speed decanter centrifuges and high speed decanter centrifuges. Per their electric control system they are fixed speed and variable speed available.

Like GNLW363C series decanter centrifuges, GN has 4 models while 5 options available, they are highest configuration ones, for waste management use mostly, and economic standard ones. And for each configuration, end users could choose fixed speed or VFD control panel. For the economic standard option, GN has positive pressurized VFD control panel with PLC and normal VFD control panel for option.

What feeding pumps are used respectively or the decanter centrifuges per their control panels’ differences?

  1. For fixed speed control panel decanter centrifuges, you could use both the submersible slurry pump and the screw pump or called mono pump. In case of fixed speed decanter centrifuge, normally no need to change the speed and feeding capacity which is already set with a formula of centrifuge feeding speed and gearbox ratio and motor rotating speed, and etc. In order to change the feeding capacity when using the submersible slurry pump, extra liquid fed to the centrifuge could flow back via the overflow pipeline of the centrifuge. In case of the screw pump, the end user could install a mechanical devise on the screw pump as a manual valve. Such is shaped as a wheel and could be switched left or right in order to get a suitable feeding capacity.
  2. For the VFD controlled decanter centrifuges, the common and practical solution is always the mono pump or screw pump. The screw pump’s motor is connected with the control panel and on the other side of the motor is the gearbox connected with the pump rotating part. By changing the HZ via control panel, the directly connected screw pump would change the feeding speed and accordingly the feeding capacity.
