GN Solids Control Equipment Reduce Your Environmental Footprint

GN Solids control system involves the utilization of shale shaker, mud cleaner and decanter centrifuges to process drilling fluids and remove the expected solids prior to, during, and after the drilling operation. We mainly supplies three phases of solids control system including prior to drilling: mud mixing system, during drilling: mud reclaim system and after drilling: drilling cuttings waste management system.

GN is highly experienced in offering qualified solids control equipment for all types of drilling fluids in the world.

Prior to Drilling

Mud mixing system is applied for mixing all kinds of chemical to formulate the drilling fluids. Generally, we apply the centrifugal pump, venturi hopper even shear pump for circulating and mixing drilling mud. The capacity of centrifugal pump ranges from 200GPM to 1408 GPM. Shear pump is capable of reducing the cost of mixing polymers an clays while improve the mud properties. Also, we utilize the mud agitator and mud gun to suspense solids prevent from sediment. Regarding to the customer’s requirement, we are able to customize the length of shaft of mud agitator and length of mud gun

During Drilling

Solids Control equipment are capable of reclaiming the drilling fluids. Technically, we offer the series of equipment including shale shaker, desander, desilter the combination of desander cones and desitler cones and decanter centrifuge. The four steps of solids control equipment remove different size of solids in order keep the drilling fluids property 

After Drilling

Drilling cuttings waste management system is use for processing the drilling cutting s during drilling and after drilling. Especially, drilling cuttings waste management system is for offshore project. When offshore project produce some drilling cuttings, contractor normally keep the cuttings and subsequently reclaim in the land. Therefore, our drilling cuttings waste management system is widely used for onshore and offshore drilling project.  Our field experienced technician staff will work to assure that every project has a solution optimized for the drilling cutting being disposed.

Solids Control Wear Part- Shaker Screen

Within the solids control industry, shaker is the primary solids control unit, and shaker screen is a vital put on part for shale shaker. GN use the advanced technology to produce a number of brand shaker screens. Being an API and ISO licensed company, GN offers from API 20 to API 400 shaker screen.

Top quality and Flexibility Test

GN screens are fabricated in an array of API dimensions to make sure maximum solids control efficiency no matter the formations drilled. Our high-strength and strengthened material frames and stainless steel sieve are lighter and much more durable than usual shaker screen. What results is operational existence that’s nearly double those of other screens available on the market.

GN use constant observation, adjusted test liquids, Dry sieve testing procedure and periodic sampling testing to represent each API sieve class. GN regularly takes shaker screen to check percent elongation, ductility, wire count and tensile strength so assure each shaker screen qualtiy

 Although we check carefully each shaker screen, couples of clients still complain the shaker screen blocked. You will find some reason by which make the shaker screen clogged

–  How big solids is near to the dimension of opening sieve

2.  Drilling liquids/mud is that contains an excessive amount of moisture

3.  Particle/solids have static cling throughout the separation process

4.  vibrating mesh wire through too thick

5 .  The form of huge solids is flaky

6.  some thicker kinds of mine screen, pass design is uncommon

Note:  the contaminants/solids are essentially irregular shape, therefore the reasons of block are also different. To be able to better prevent screen clogged filter while watching products, perform some analysis and judgment before we decide the shaker screen. When you wish to filter fine contaminants or consists of more mud, water will probably cause blockage from the primary factors sieve. Hence the requirement for moisture testing contaminants, once the water is more than 5%, the requirement for blocking particulate drying out When water is more than 8% use wet sieving. Screening performing and the other reasonable regulation mesh tension can also be a highly effective measure to effectively prevent inserting sieve.

Maintaining a GN Decanter Centrifuge

Now many drilling industries of solid control plus some other fields are utilizing increasingly more decanter centrifuges because of the superb performances of these. So it’s quite vital that you know some repair understanding to keep the decanter centrifuge inside a good shape.

As everyone knows, when we may take proper care of the device carefully and properly utilize it within our daily processing course and do regular and proper upkeep of a decanter centrifuge machine, the machine’s existence could be extended. Therefore we will mop the exterior from the machine to make certain it’s clean and dry to prevent any rust and dirt to get involved with the inter from the drilling centrifuge machine. Next, the conveyor and also the offerring belt are extremely simple to be loose within our daily utilisation of the machine, therefore it have to be frequently examined and also to be exchanged if they’re fail to work well. We ought to also look into the easily putting on areas of the device and also the operating situation from the electric system from the machine and fix importance towards the battery system regularly.

Differential mechanism ought to keep high rate of concentricity using the primary body from the decanter centrifuge machine when installed, when the connection backward and forward areas of a piece of equipment, we ought to then place a cooper nick between your differential mechanism and also the offerring belt to make certain the required trembling once the machine is working.

Because of assorted reasons, the device cannot work along with the beginning, this phenomenon can’t be prevented. We will have to do a change from the machine after a little working duration of a decanter centrifuge machine.

Aslo a great brand is essential essential for our future maintenance and repairing. So thanks for visiting request for technical the aid of our technical engineer:

The decanter centrifuge made by GN Solids Control

Decanter Centrifuge is the final stage equipment inside a complete solids control system. After being released from the desilter or perhaps a mud cleaner, drilling mud is going to be pumped into decanter centrifuge with a screw pump. A decanter centrifuge normally can separate solids having a diameter between two to seven microns out.  Regarding a decanter centrifuge’s working principle, first of all I’d prefer to help remind you of the bottle that contains the mix of sand and water, you will find that sand is settled at the base, as the water is suspended onto it. That since the sand likes a greater sedimentation velocity compared to water because of its bigger density. Therefore we should make reference to a laundry-drier which is often used to dry cleaned clothes by centrifugal pressure, and the higher the centrifugal pressure is, the shorter time that it will take to dry clothes. Mix the 2 suggestions, you will be aware the way a decanter centrifuge works. GN’s decanter centrifuge having a mid-speed can remove solids of five to seven microns out, and GN’s high-speed decanter centrifuge can separate solids of two to five microns out. Besides to be the final equipment inside a solids control system, the decanter centrifuge made by GN Solids Control may also be used inside a drilling waste management system.

GN’s decanter centrifuge has got the following benefits and advantages.

First, because the first API licensed solids control company in China, GN solids control is also licensed by: Europe DNV CE, HSE, ISO9001, Russia TP&TC. And GN first of all built an USA based solid control company: GN Solids America.

Then, GN’s decanter centrifuge switches into many a brand new design. For instance, tungsten carbide tiles are fixed around the screw to safeguard it from put on, and also the tiles are simpler to become changed

Affirmatively, the decanter centrifuge made by GN will be your best option.
