Russia large energy company has purchased decanter centrifuge, vacuum degasser and mud cleaner from us for solids control system. Obviously, they have visited our manufacuturer firstly and subsequently negotiate with us about the price and shipping condition. They express the strong willingness to establish business with us in the future because of our qualified equipment and competitive price.12B 副本

The Advantages of GN Equipment.

 1. GN different models of Decanter Centrifuge are available for recovering the barite, diamond drilling project and separate the solids from drilling fluids. Duplex stainless steel 2205 material and tungsten carbide maximum protect the screw from solids damage in order to keep the long lifespan.VLUU L100, M100  / Samsung L100, M100

2. GNZCQ270/360 Vacuum degasser has the capabilities for ensuring the proper mud weight and removing the dangerous gas in the prevention of potential blowouts. It is with a self-contained installation and infrared level sensor to prevent the overflow.

3. Mud cleaner is a combination of desander, disilter cones and shale shaker.The 10 inch desander cone and 4 inch desilter cone separate the undesired solids by centrifugal force. The bottom shaker is used as the drying unit to process the solids from desander and desilter.

GN solids control ,a specialised mud system manufacture for oil&gas drilling,HDD&CBM drilling,water well drilling .till now our water well drilling mud system have been working in Mongolia,Libya Susan and some South Asia market.

An Overview on Drilling Operations in Sudan

Water Wells Drilling background:

Seasonal shallow wells in alluvial sediments deposited along the seasonal streams courses locally known as Jamam/ Meshish providing very limited water.

Hand dug wells lined with bricks and stones are oldest well known water technique.

The first deep borehole in Sudan was drilled in 1919 at Um Ruwaba using a steam driver percussion rig.

Rotary drilling rigs were introduced in early fifth of last century. Down the hole hammer rigs (DHH) were introduced by Unicef in 1978 for drilling of slim boreholes .

Drilling systems in Sudan:

A. Down The Hole drilling using air drilling system.

B. Rotary drilling system using liquids – mainly bentonite. 

C. Percussion drilling system.

D. Manual digging using experiences of local skilled people.



GN supplied a lot of mud system for water well drilling, and the first one is exported to Mongolia, while the customer checked our system performance and indicate their sub-company in Mongolia to purchase from GN. Then we exported Water well drilling mud recycling system to Mongolia, and Water well drilling mud cleaning and mixing unit to Mongolia, Then exported Two Unit 200GPM Mud Recycling System Delivery to Australia

Today another system to Mongolia are ready. This system contains our new small shaker, MINI cleaner, and jet mud mixing system.·

 The drilling of water wells improved over the last two years, which indicating better investment, funding and improving sector drilling capacities.

Mud gas separator for drilling fluids solids control

Mud gas separators in other countries also called Poor boy degasser,Liquid-gas separators,Mud/Gas Separators, etc.GN Solids Control  designs and manufactures ZYQ Mud gas Separators. Mud gas Separators is an extremely reliable, vital piece of safety equipment for today’s drilling operations. It is ideal for use where drilling is likely to encounter large volumes of gas, sour gas or when an operator is drilling with an under balanced mud column. This Mud gas Separators is primarily used to separate and safely vent large pockets of free gas, that may include toxic gases such as hydrogen sulfide, etc. from the drilling fluids processing system.

ZYQ series Mud gas separator(Poor Boy Degasser) is professional equipment to treat the gas invade mud. When the drilling mud result gas invade, the proportion of its weight and viscosity have a greater deviation not to meet the requirements of drilling. The serious situation is that would cause Chung well, and even blowout accident occurred, if not to treat it timely.

Oilfield drilling poor boy degasser, that removes air or gases (methane, H2S, CO2 and others) from drilling liquids. It is mainly used to remove the big bubbles with the diameter of about ≥Φ3mm.Most of these bubbles are the expanded gas filled in the drilling fluid in annular of wellbore. It would cause well kick if mot to remove it timely.

There are two generic types that work by both expanding the size of the gas bubbles entrained in the mud (by pulling a vacuum on the mud) and by increasing the surface area available to the mud so that bubbles escape (through the use of various cascading baffle plates). If the gas content in the mud is high, a mud gas separator or “poor boy degasser” is used, because it has a higher capacity than standard degassers and routes the evolved gases away from the rig to a flaring area complete with an ignition source.

 What is the features of GN mud gas separator? 1 Matched flare Ignition device available, to provide complete solution for you.

 GN Flare Ignition Device of blown down fuel gas is a kind of handling arrangement used in blown down natural gas, the tail gas from collecting and distributing station of natural gas and from refinery. And being a kind of security and environmental protection equipment, the flare ignition device can be used to have the blown down harmful gas ignited and burned to prevent the environment and security from being endangered. The flare ignition device, apart from being used in the refinery and gas distribution station, may be matched with Mud Gas Separator. And now, as a matured product it has been extensively used in petroleum drilling engineering.

 2 Coating and Painting:

 External coating 3 layers, Internal coating 2 layers.

 External coating:

Surface preparation: Commercial blast SA2, SSPC-SP6

Primer coat: (Kansai & Cosco)Japan Brand epoxy zinc-rich anticorrosive paint

Intermediate coat: micaceous iron oxide anchor coat

Top coat : aliphatic polyurethane top coat

The External coating system is composed of zinc-rich epoxy primer, micaceous iron oxide anchor coat and aliphatic polyurethane top coat, which is with advantages of good antiseptic effect and Durability.
