GN Oil Drilling Solids Control Equipment

Traditional Mongoose PT shaker screen is made of steel frame, composite screens have the following advantages compared with steel frame screens:

Higher throughput, Longer life, Fewer replacements, Lower cost.

The composite screen’s weight is much lighter than steel frame screen, and same with the original HIFLO screen. But the price is also triple more than the steel frame screens. For some of the clients who care the screen replacement time and service life, composite screen will be the ideal choice.

Shale shaker can be utilized in 2 ways for the rig.

1^st utilization is for rig solids control system as the first separation equipments, by this way, some of the cuttings with drilling fluids will be separated out. 

2^nd utilization is for drilling cuttings separation, they use fine mesh screen to dry the drilling cuttings and separate usable drilling fluids and back to the rig. The drilling cutting shaker also called hi-G shaker.To continue drying the cuttings, you should use cutting dryer.

The left picture is a centrifuge bowl, which is the main component for the drilling fluids decanter centrifuge. It is mainly composed of taper cylinder, straight cone, screw propeller(inside) and collection box. All of them are made of Duplex stainless steel, which is high strength and high corrosion resistance.

And the bearings in big end and small end are made of SKF bearing. Especially the screw propeller of GN centrifuge is protected by Tungsten carbide tiles, not traditional protection way-coated with Tungsten alloy on the surface.

The picture right showed a mini mud cleaner used for Geothermal well drilling. There are 2 mud tanks in the mud system, one is treatment tank, 1 is storage tank. On the 1^st treatment tank, there is a GNZS703 linear motion shale shaker, and 2 mini mud cleaner with desander cone and desilter cone separately.

Mini mud cleaner has larger screen area than desander, desilter with small underflow shaker, so the treating effect is better, and its cost is cheaper than mud cleaner with large underflow shaker. It is the ideal equipments for Geothermal well drilling.

Shear pump is a kind of centrifugal pump, usually it is used together with mud hopper, it can mix effectively and hydrate completely the material added in the drilling fluid, save the mud material , reduce the time of configuration. If there is a pill tank or pill compartment, you must use shear pump with hopper, we called it jet shearing device.

It has better mixing efficiency than jet mud mixer, which is composed of centrifugal pump and mud hopper.

Do you know what is Vacuum Degasser and its function?

It is the 2nd phase solids control equipment, which is used after shale shaker, to separate various gas from the invasive drilling mud, so that it can protect decander, desilter cone and centrifugal pumps impeller.

 Different with Derrick vacuum degasser, this GN vacuum degasser do not need suction pump, it has self-suction ability, so it can save energy and drilling cost.

GN just cambe back from Moscow for the12 th Moscow International exhibition “Oil and Gas”(short name MIOGE 2012). We have a 36m2 booth there, originally we plan to take a decanter centrifuge and a shale shaker to attend the show, because of some reason of Customs clearance in Russia, we can not meet the exhibition time. 

During the show, many professional clients showed interests to our equipments, including competitors Derrick, MI-Swaco, Kem-tron.

Full name of CBM is Coal Bed Methan,the picture right shows a CBM drilling mud system from GN solids control in site. Our engineer are installing them and connecting the pipeline with triplex mud pump.They will work with the clients’s workers till the commissioning is finished. 

Except for CBM drilling mud system, our engineer also ever serviced for HDD drilling mud system, water well drilling mud system, oil drilling mud system，dredging slurry separation system, and other environment protection projects. 

This is a mud tank system for Kazakhstan, we also provide awning for the mud tank system. Every year GN produced hundreds of mud tank system and exported to over 60 countries in the world. Most of them are used for oilfield drilling rigs.

Before delivery, we will do Penetrant Test and Leakage Test will full of water in the tank for over 48hours, hand rail and walkway will be packaged in a bundle and on top of the tank.

GN can design customized mud tank system according to your requirement.  

Our maintenance engineer just came back from South-east Asia for 3 units of mud mixing unit installation and commissioning service.

Volume of each mud mixing tank is 150bbl, with 1 mud agitator, 1 hopper, 1 Mission pump. Its mixing capacity is 500gallons per minute. All the tank top is covered by galvanized steel gratings. It is designed for easy transportation and easy maintenance.

We can make customized mud mixing unit with various volume.
