GN Solids Control is a manufacturer of drilling mud solids control equipment, of which Africa is one of GN’s main markets, especially with the high oil price this year, the African market is becoming more and more important.

Last week, GN Solids Control delivered a batch of drilling mud solids control centrifuges to an African drilling rig contractor. Centrifuge is the key processing equipment for solid phase control of drilling mud. Usually, after the drilling mud is returned from the drilling rig, the harmful air is removed by the liquid-gas separator, and then sent to the shale shaker, and then further removed by the desander or desilter. The pellets are finally sent to a decanter centrifuge.

 

The GN Solids Control decanter centrifuge can remove solid particles larger than 2-5 microns, no matter light gravity drilling mud or heavy gravity drilling mud, the rotor and the augers operate at different speeds to realize the solid phase control of the drilling fluid. GN decanters can also run at low speed to recover barite from drilling mud.

If sorted by drum diameter, GN Solids Control decanters are available in 220mm, 360mm, 450mm, 550mm and 760mm models. The rotating shares of all decanter centrifuges are centrifugally cast, the solid discharge port is protected by a tungsten carbide alloy sleeve, and the screw pusher is inlaid with tungsten carbide hard alloy sheets, which are more wear-resistant and have a longer service life and have been repaired and replaced.

This project GN Solids Control provides 6 sets of 360mm diameter decanter centrifuges, all of which are controlled by frequency conversion cabinets and fixed by HMI touch screen, which can easily change the operating parameters such as speed and differential speed. The centrifuge is fixed with a temperature sensor and a vibration sensor to monitor the operation of the two main bearings, which can ensure the normal operation of the equipment without overheating and the abnormal vibration of the entire rotating assembly.

GN Solids Control has been committed to the design and equipment manufacturing of solid-liquid separation processing systems for many years. Since its establishment, GN Solids Control has reached long-term cooperative relations with many well-known drilling companies, providing customers with various solid-liquid separation and treatment equipment with high quality and quantity every year.

Last week, a well-known petrochemical company purchased two sets of trenchless HDD mud purification and treatment systems.

One of them is a 240m3/h (1000GPM) trenchless mud purification system, including:

a. 2 shale shaker GNZS703F

b. 1 set of mud cleaner GNZS70F-1S8N

c, 1 large drum dewatering centrifuge GNLW452D

d. 2 sets of mud tanks

e. 1 set of jet mixing device

 

GN Solids Control trenchless mud purification systems have the following features:

1. The shaker motor adopts Italian brand motor or American brand motor

2. The cyclone is made of 100% high-quality polyurethane and has a long service life

3. The centrifuge pusher is made of duplex stainless steel 2205 or 2304, and the discharge port is protected by a tungsten carbide wear-resistant alloy sleeve, which has a long service life

4. The centrifugal pumps in the jet device all use mechanical seals, which have a long service life and are easy to maintain.

5. Adopt Japanese Kansai brand epoxy zinc-rich marine heavy anti-corrosion paint

6. The multi-functional integrated design can meet the needs of mud purification and recycling, mixing and storage.

GN Solids Control has been committed to the design and equipment manufacturing of solid-liquid separation processing systems for many years. Since its establishment, GN Solids Control has reached a long-term cooperative relationship with many well-known drilling companies, providing customers with various solid-liquid separation treatment solutions with high quality and quantity every year, and equipment required for solids control services, such as decanter centrifuges, vertical cutting dryer and other products.

Last week, GN Solids Control provided a well-known company with dual-track drilling fluid shakers for offshore drilling platforms.

With the continuous development of drilling technology, the drilling depth is getting deeper and the geological conditions are becoming more and more complicated, and the drilling construction has higher and higher requirements on the drilling fluid shaker. Therefore, the liquid vibrating screen was born.

The dual-model drilling fluid shale shaker is a combination of the linear shale shaker and the translational elliptical unit. It has the advantages of these two shale shaker. When drilling in the sandstone bottom layer, the linear shaker is used to meet the sand discharge speed. Fast, processing high volume needs. In the mudstone layer, the translational elliptical vibration trajectory is adopted to reduce the phenomenon of screen paste.

 

GN Solids Control dual model shaker has the following features:

The excitation force can be adjusted, and the high G excitation strength meets the separation of the specific gravity of the high-viscosity mud; the overall heat treatment of the screen box can meet the long-term work under high excitation strength; the bottom frame of the screen box is made of stainless steel, which has strong corrosion resistance and long service life; The box angle can be adjusted synchronously on one side, which can meet the requirements of the screen box angle adjustment without stopping, and the operation is stable; the plate frame screen and the wedge-type screen pressing device are convenient for the rapid replacement of the screen; the brand vibration motor, Martin motor or OLI motor is adopted ; Electrical components are selected from well-known brands such as Siemens or Schneider; the slurry feeding tank adopts cofferdam type or overhead type to buffer the mud and reduce the impact on the screen.

GN Solids Control is a professional manufacturer of decanter centrifuges. It has been committed to the design and development of decanter centrifuges for industrial separation for many years. After more than ten years of continuous development and innovation, GN Solids Control has sold its products to the world. In many countries and regions, GN Solids Control has been able to design and manufacture various types of centrifuges with drum diameters as small as 200mm (9 inches) and as large as 760mm (30 inches). Recently, our company has successfully produced a batch of portable micro decanter centrifuges for users in the north America for mining core drilling, and sent them to the customer’s site, which was affirmed by the customer.

 

GN Solids Control 220 series decanter centrifuges are small drum centrifuges with a drum size of 220mm (9 inches) and compact design structure. They are widely used in solid-liquid separation under conditions that require small throughput or limited space. , and this series of centrifuges are also a good choice for the experimental test of decanter centrifuges. According to different working conditions of customers, our company can also provide customers with three different control configuration options: constant speed control, frequency conversion control and full hydraulic control.

The material of the 220 series decanter centrifuge bowl is made of two-way stainless steel SS2205, which is cast by centrifuge. In addition, the slag discharge port of the centrifuge and the slurry discharge port of the pusher are all protected by tungsten carbide carbide inlays, which have high durability and longer service life; the centrifuge pusher is protected by a replaceable wear-resistant alloy sheet, which can effectively extend the service life and easy maintenance.
