GN 22inch decanter centrifuge for fast drilling

GNLW553-VFD centrifuge is 22inch jar size centrifuge. This is major bowl big volume centrifuge can be used for fast drilling. But not many clients choose this kind of model centrifuge.

Last week GN solids control shipped a 3 mud tank recycling system for CBM project in Shanxi, China. This is a 500gpm mud recycling system with 1 unit of shale shaker, 1 unit of mud cleaner and 1 unit of middle speed decanter centrifuge. CBM mud recycling system is different with HDD mud recycling system and oil drilling solids control system, the design should be compact design and with smaller storage capacity.

This system is customized design after communication with the client. But the separation cut point should be smaller compared with HDD mud recycling system, normally desilter cone separation point is 15 ~ 20 microns, which is enough and acceptable for Horizontal directional drilling. But after long period drilling, the ultra fine solids will accumulated in the drilling fluids, which is not suitable for preparing the new drilling mud and re-used for drilling, that is why a decanter centrifuge is adopted in the mud system, the separation cut point is 5 ~ 7 microns.
The configuration of the CBM drilling mud recycling system is as below:

(1)    3 panel shale shaker GNZS703E as the first phase cleaning equipment, to separate big solids from drilling fluids
(2)    GNZJ703E-1S8N mud cleaner with 500gpm treating capacity, 3 panel bottom shaker and 1 pc of desander cone and 8 pcs of desilter cone, the separation point of desander cone is 40 microns and separation point of desilter cone is 20 microns.
(3)    18 inch middle speed decanter centrifuge

Solids control equipments are commonly used in land rig drilling project for drilling fluids recycling and cleaning. Properly recycling the drilling fluids could significantly reduce the cost on drilling fluids and the discharged volume of waste cuttings. Offshore drilling also produces drilling cuttings and other waste material need to be treated. Among the material produced, the used drilling fluid is the first one need to be disposed.

There are many places where the solids control equipment would be used, one of that is the equipment used on offshore drilling platform. A very compact flat including all the drilling machinery standing firmly in the sea, when drilling, it will need the drilling fluids recycling system for treating the used drilling fluids. Due the limited space on offshore platform, the driller always adopt the double or triple layers shale shaker as the primary separation on used drilling fluids. The mud cleaning system on offshore platform includes all the necessary equipment comparing with land rig, just working on the sea.

Almost all the offshore rig platform has enough mud tanks for storage the drilling fluids. However, when there is over much ultra fine solids in the drilling fluids, the drilling fluids is not be able to be used anymore if without any further separation. At this time, this type used drilling fluids need to be transported to land for treatment. The barge ship is used to transport this type drilling fluids from offshore rig platform to the land and provide new and active drilling fluids for the rig. The barge ship need have many mud storage tanks so that it can bring sufficient mud to the offshore rig. The barge ship need also have the mud mixing equipment for mud mixing system on the ship. The mud agitator and mud gun would also be needed for mud mixing system.

More attention should be given to the explosion proof of the motor and control cabinet, as it will be more dangerous if there is a fire on offshore rig or barge ship than on land rig. Thus, the electric components used for offshore should be strictly marin explosion proof standard. The other thing need to be given more attention is sufficient wear parts storage for offshore rig, as we known, it will be much difficult for the drilling to get a small wear part once the equipment shut down. That will be a waste for both time and funds.

 

GN solids control brand decanter centrifuge has been used for high gravity solids drilling fluids successfully in Shengli Oilfield in domestic market. The features of the drilling waste fluids for this zero-discharge projects are as below:

High viscosity, high corrosive, high oil content, high pollution, difficult to be treated, high treating cost, etc.
The technical datas of the drilling waste management for the zero-discharge project is as below:
Drilling waste total volume: About 2000 tons each drilling period, each period is about 7~15 days
Solids content in the drilling waste fluids: experienced data 2%
Dry solids : 40 tons / period( approx)
The traditional waste water treatment equipment is hard to work continuously 24 hours automatically, the drilling waste cuttings is increased and discharged from shale shaker, desander, desilter , decanter centrifuge, especially for the shale shaker discharged cuttings, much of mud, cuttings are included in the drilling fluids, the cuttings size is between 5~ 20mm, If treated by the traditional belt filter for drying, the filter will be damaged and blocked.
After study and test in the client’s rig site, GN engineer team adopted our GNLW363CG-VFD decanter centrifuge for drilling waste treatment of this project. Our decanter centrifuge is 3 VFD control for main motor, back drive motor and pump motor, which can be used for different applications.

Year 2008, GN obtained the API Certificate, as well as GN was the first China’s Solids Control company who all got the API Certification.
Later, year after year, GN obtained certificate of ISO, DNV CE, HSE and and so on, many certificates to show GN’s quality and management ability. Meanwhile, GN Solids Control’s producing line expanded in the traditional solids control for the field of drilling waste management, including the decanter centrifuge and vertical cuttings dryer. And later, the dewatering product and dewatering package, then the solidification unit along with TDU system came out via GN engineer team.

Congrats, GN! And we hope as well as believe, GN will do considerably better!

This isn’t the first set containerized drilling waste management system sent to The ussr. To ensure the machinery running effortlessly in cold weather, customers coming from Russia always prefer this specific containerized design that could create all equipment indoor. Driver could run the equipment on the inside, and this standard container dimensions are also convenient for method of travel by sea.
Customized drilling Waste Management System
Top to bottom cuttings dryer unit is among the core equipment for drilling waste management system, it is always employed for drying the waste slurry to get much dryer strong discharges and recover fluid. The dryer unit in this particular project is GN’s Deborah version model with typical RPM of 900, built with air knife system in addition to flushing system for cleansing of screen and liquefied discharge circle chute through equipment running to avoid mass inside the dryer unit.

Hose-pipe pump is used to send the waste material into the dryer unit. The advantage of using the hose pipe pump is less limitation to find it and this type pump works very well for excessive density waste transportation. Mess conveyor unit is supplied to install under the dryer system to deliver the solid discharges out to the container. And out of doors the container, there is waste material collecting box to collect typically the waste coming from the conveyor. This particular waste collecting box can also be design and made by GN solids control with cover for hazardous substance further transportation.
GN Actually provided 4 sets drilling waste management system such as vertical cuttings dryer and also VFD model decanter centrifuge to Baker Hughes within Russia. Their operator built a very big canvas household to put the whole system within for better performance with small weather temperature.
Nowadays, GN has sent over forty five units dryer units for you to customers, some units tend to be modular design for easy configuration onsite, while some others are cemented to the skid system combined with decanter centrifuge unit with regard to customers’ requirement on total processing of waste.

GN solids control is one of the leading manufacturer for industry solids-water separation unit in the world, our mud recycling system/ water recycling system has been sold to over 60 countries in the world. Dredging slurry separation unit is one of our main products for environmental service, we also produce desander unit for pilings, water recycling system for TBM or pipe jacking machine, mud cleaning system for HDD and water well drilling, our solids control equipments and system are also used for oil & gas drilling applications.

The common process for dredging slurry separation system is as below:
Firstly received the sludge from the dredger which is mixed the water, stones, rubbish and fine solids and transfer the sludge from the dredge boat to GN dredging slurry separation unit by pump. We will use coarse mesh screens( polyurethane shaker screens for longer working life, especially suitable to separate big solids like stones, bricks, tree branch,etc) to separate big solids firstly, the purpose is to protect the equipments in the further process and improve the efficiency of the complete system.
We will use multi shale shakers because most of the dredging projects need a very big treating capacity. In the second step we will use fine mesh screen to separate fine solids, sometimes we will use desander cone and desilter cone with centrifugal pumps as feeding pump, but the cones are only as option, because of the high power consumption.

Gn solid control is the most cutting-edge technology, solids control equipment manufacturer in China, which produces the decanter centrifuge has been approval by the largest oil giant enterprises of domestic and international companies.

In the just-concluded 2016 CIPPE oil show, GN solids control display different series of the centrifuge, series of small decanter centrifuge from 220 to 550 mm of big drum centrifuge, lined up at the scene of the exhibition, has made a lot of audience attention to end users.

Especially model GNLW363 decanter centrifuge, both in the appearance of the old version and the new design was shown in the CIPPE 2016 booths, so what is the difference of GNLW363 decanter centrifuge new generation?The following simple statements.

1, the first generation of GNLW363, originally designed for 360 mm horizontal spiral sedimentation centrifuge, in this two motor, one is main motor ,another is a auxiliary, respectively installed on both ends of the centrifuge.Though, it is with the highest level of materials, the design concept of the centrifuge is basically the same with other domestic counterparts of the old.
2, the second generation GNLW363B, more international, with GN solid control has sold the products in many countries and regions of the world, as well as the champions league to the product design is becoming more and more internationalized, GNLW363B horizontal screw centrifuge before the two motor position has a into one end is at each end of the two, mainly is to increase the operator have more space and centrifuges operating characteristics of easy to maintain, stable operation.
3, the third generation GNLW363C sedimentation centrifuge, in addition to the basic drilling mud solid control can also be used for oilfield drilling waste management pulp processing, it is similar to GNLW363B, two motor on one side.But on the other details GNLW363C also has a better update on structure, structure, based on the B version upgrade C version of the centrifuge and been used in many fields.Such as sludge separation, flocculation and dewatering unit, waste pulp processing, etc., with the user feedback, after upgrade C version of the centrifuge in use process compared to B version, processing capacity increased by 50%, continuity of operations, rugged conditions objection to adapt.
4, the fourth generation of GNLW363D, the inside of the design and GNLW363C are similar, but the outlook is completely different, because the structure is higher than C version is more compact, the stability, its total weight is reduced by 30%, is advantageous for the urgent needs air.In terms of use and transport greatly saves time and money.

Most of the horizontal directional mud cleaning system is not equipped with decanter centrifuge unit as by using the 3-phase separation system including shale shaker, de-sander and de-silter unit, it can work good enough for removing the solids from drilling fluids. Centrifuge is relative high cost, which is also a reason the drilling contractor doesn’t equip it in the mud system.

However, for some high request drilling condition, the driller may use the heavy mud for better drilling performance. Sometimes the drillers add the certain chemicals to make the drilling mud heavier so that the mud can better protect the wall of the drilling hole. If the driller went to drill another well, the heavy chemicals need to be separated, and then the centrifuge could be used to do this job. In some other conditions, after many times recycling of the drilling mud, there is much ultra fine solid particles that cannot be removed by the shaker and cyclone unit, and then the centrifuge unit is needed.

GN Solids Control has nearly 10 years in fabricating the drilling mud system for HDD projects. This type mud cleaning system need to be compact structure and easy for transportation. See the picture in this article, both the de-sander and de-silter unit are equipped with under flow shaker for drying the discharged solids. The shakers used are 2-layer screen design. The bottom layer screen is used as primary shaker and upper layer screen to dry the discharges out from the cyclone units. This design greatly reduces the footprint of the mud system. And all mud tank top surface equipment are pre-installed on a frame with same base dimension as storage tank. When transport the mud system, the shaker and centrifuge units could be removed by lifting the frame for fast disassemble. With the frame, the equipment could be easily transported by flat bed trailer.

GN can provide both standard and customized HDD mud system for clients. Just send us your request, and then you will get a satisfying and cost effective solution.
