   Four Sets of GN 1000GPM Mud Reycling For China Petroleum Pipeline Bureau

As the largest contractor of Horizontal Directional Drilling in China, China Petroleum Pipeline Bureau( abrreviated to CPP) has become one of the most professional HDD contractors in the world with over twenty years’ growing along with manys Horizontal Directional Drilling project in China and foreign countries especially in Asia. Hebei GN Solids Control Co., Ltd has establishd over 5 yesrs partnershipp with CPP since GN’s establishment and has pointed as supplier of mud recycling system for Horizontal Directional Drilling to CPP. During these years, Hebei GN Solids Control has manufactured and delivered over 30 sets mud recyling system to CPP. And now another 2 sets of 1000 GPM mud recycling system are now ready for delivery,

and two more mud recycling system are now under construction.


Below is the full detials about the two customerized mud recycling systems with medium speed decanter centrifuges to reach up to a four stage treatment mud recycling system with a capacity of 1000 GPM.

1 set GNZJ705-2S mud desander cleaner with double deck shale shaker totally 5 pieces of shaker screens and 2 sets 10’’ desander cones as a two-stage treatment function in one machine. The bottom deck of shale shaker will serve as the first stage treatment equipment for coarse solid separation, and then the desander cones for second stage treatment with the top deck as bottom shaker to dry the solids and collect more liquids.

1 set GNZJ705-12N mud desilter cleaner, same design as GNZJ705-2S mud desander cleaner.

2 set GNLW452VFD middle speed centrifuge , this is the four stage separation machine. As the mud system is designed with bigger capacity 1000gpm, we match 2 sets decanter centrifuge to reduce mud weight and get better performance. The recycled drilling mud after centrifuge can be more clean and suit for deeper drilling. 

2 set 20 feet container size mud tank and 2 set steel frame for fast installation.

GN Decanter Centrifuge Working for America Transocean Offshore Rig

on . Posted in News

GN solids control is the 1st API certified solids control equipment and system company in China, in the next few years, GN solids control is also certified by CE which is always required when exported to Europe. With these certificates, GN product has been exported to more than 60 countries all over the world, especially GN decanter centrifuge. Each year, about one hundred sets of GN decanter centrifuge, both fixed speed and varied speed are exported, and 70% of them to Africa and the Middle East, also to Europe and America. Recently one of GN sales after team came back after finishing service for American Transocean Offshore Rig, bring GN solids control valuable drilling site data. This customer uses GN varied speed decanter centrifuge to separated fine solids, and reduce the mud weight. In this work site, two sets of decanter centrifuge are used, one from Baker Hughes Drilling Fluids Environmental Service, the other from the customer purchasing GN decanter centrifuge to do this service. Sometimes, only one decanter centrifuge is used, while sometimes both of the two are used when the treating capacity is required larger.

When doing service, our sales team really encountered some problem and challenges. The first one is that the feeding pump is installed lower from the decanter centrifuge because of the small space on the offshore drilling platform. And then the feeding pipe from the pump to decanter centrifuge are very tortuous with steel pipe and rubber pipe. GN professional engineers proposed solutions after carefully check and analyze the layout in working site. And then the feeding pump works well, delivering mud to the decanter centrifuge to process stably. GN solids control is really an expert on solids control equipment, especially on GN decanter centrifuge.


GN Has Delivered Poor Boy Degasser to Its Foreign Customer

GN Has Delivered Poor Boy Degasser to Its Foreign Customer


Hebei GN Solids Control Co., Ltd is an expert in manufacturing solids control equipment and system. Usually in a solids control system,

for safety objectives, a mud and gas separator usually used to remove the dangerous gas out from the mud, because these dangerous

gas will cause explosion if not separated but directly led to the shale shaker for processing. As we know that shale shaker is the first stage

equipment. Before mud arrives to the shale shaker, the dangerous gas will be separated out.

Poor Boy Degasser

Usually we used a mud gas separator to separates dangerous gas out of the mud, and a mud gas separator is also known as poor boy degasser.

Recently, GN Solids Control has delivered poor boy degasser to its customer. This year GN has delivered 4 sets of mud gas degasser to Canada,

2 to Indonesia, and 2 to France. Except poor boy degasser, GN product has been exported to more than 60 countries in the world and has achieved

a well known brand :GN Brand.

Delivery of Mud Gas Separator

Actually, mud gas separator(poor boy degasser)’s structure is not complicated. I wil discuss its structure next. GN poor boy degasser is simple structured

with a separation vessel of diameter 1000mm. Inside of the vessel; there are several pieces of steel buffer plate on which the high pressure drilling mud would impact.

After collision, the gas invaded in the drilling mud would get out and guided out from the 8” vent pipeline on the top of the separation vessel, while the mud would go down

and accumulated at the bottom of the vessel, then flow to the into the solids control system through the 10” outlet. Though its structure is simple, but it plays an important role for safe drilling.


GN Mini Centrifuge With Compact Design to Save Space And Cost

GN Mini Decanter Centrifuge With Compact Design to Save Space And Cost

You may take it for granted that a machine is huge monster with a large footprint and heavy weight. It always make people feel gloomy when standing before a huge machine.

But look at the following picture, how cute it is. It is a mini decanter centrifuge from GN decanter centrifuge product line. With small footprint, it is easy to remove and transport, 

it also saves a lot space for users. As to its parameter, the mainly two is treating capacity and speed. GN mini decanter centrifuge’s treating capacity or processing volume is 

6 cubic meter per hour. And its speed can reach to a maximum round per minute. And for its main feature which I will talk in next paragraph, it is always used in core drilling.

                                          Mini Decanter Centrigufe

GN mini decanter centrifuge with the model number GNLW223 mainly occupied the following features.

1.small footprint for easy moving and narrow working space

2. One motor driven mode for both the bowl and inside screw propeller. The motor drive the bowl via a belt pulley with belts, the bowl has same rotation speed as the motor. 

Meanwhile, the design of gear unit makes the input speed of the screw propeller is much lower than the bowlthe screw propeller is also driven by the motor with a belt pulley. 

Thus the existence of the differential speed leads to the centrifuge working availability.

3. High typical speed up to 4500 produce the sufficient G force to separate the very fine solids with size of 2~5 microns.

4. Material of SS304 on bowl, screw propeller and main body and protection of tungsten carbide spraying welding is for reduce the cost, but can meet the working demand well.

5. Both fixed speed and variable speed model is available

                                              Decanter Centrifuge's Material

GN Solids Control has contacted with many customers from Canada in the business of core drilling and other mining drilling. To consider the high requirement on the motor and 

control panel explosion proof standard, GN would provide the Mini centrifuge only mechanical part and the customer could find the motor and control panel locally. 

And GN has already done like this before.
