API SHAKER SCREEN

huffingtonpost:

Welp, we’re pretty sure this guy has had worse days.

As GN produce more and more solids control equipments and drilling waste management systems to satisfy customers changing demands on drilling fields or Non-dig fields, clients have higher and higher demands on GN Solids Control which is providing them the necessary costume parts such as shale shaker screens.
Now GN will soon establish his new factory to meet the needs of large quantity shaker screens. On the end of this year, GN new branch factory will help GN to produce much more shale shaker screens, and this new branch company is quite near to GN Solids Control Company. It’s such an great news for GN and for GN clients.

Usually, GN can produce from five thousand pieces shale shaker screens to eight thousand pieces shale shaker screens every month, however, considering the large need this manufacturing capacity is not enough. Anyway, on the basis of new factory, GN will solve these problems perfectly well, and GN will introduce many advanced CNC machines to improve the production, as well as hire more experienced workers to working on this special field.
For GN Solids Control, all kinds of shale shaker screens can be produced, such as the hook strip flat screens, the pyramid screens, hook strip soft screens and steel frame screens etc.
If you can name the screen, then GN will design and manufacture them. The good qualities that are followed strictly by GN engineers, so the world most famous brands can be replaceable and performed well on various different shale shakers. By using GN shale shaker screens, our clients can not only keep the same performance as the world famous brands screens, but also can same much money on the cost. That’s why our clients always call GN shale shaker screens cost effective.
With many successful experiences, GN has over sixty countries’ clients that are using his shaker screens, and we believe this is just the good beginning of GN shaker screens, in the future more and more clients will have the opportunity to get to know GN.

An Introduce of GN Mud System
GN Mud Systems are widely used in many areas, recently GN got some orders on water management from abroad.
GN technical engineer recommend one set of mud system whose treating capacity can reach to 150 gpm, and the normal treating capacity can up to 132 gpm.
This is system is including three sub-systems: The first one is mud cleaning system, the second one is Cuttings Feeding system, and the last one is
1.GN Mud cleaning system
This system is composed of one shale shaker whose shaker screen is 100 mesh, one mud cleaner which can separate particle size 15mircrons to 20 microns, one centrifugal pump to feeding the mud cleaner, as well as one mud tank which is divided into two compartments.
By using this subsystem first, the No.1 compartment which is shaker compartment can treat mud by using shale shaker, then it droped into No.1 compartment. On the other side, the mud processed by mud cleaner droped into No.2 compartment, at this time it is clean mud which can be re-used directly. For clients have higher demands, we will recommed to use decanter centrifuge to do another process.
2.GN Cuttings Feeding system
This subsystem is including one Cuttings Collection hopper and one Peristaltic pump. By using the Peristaltic pump, this system can transfer the cuttings from the collection hopper to vertical cuttings dryer. For Peristaltic pump, it’s usually used to transfer drilling mud with large density.
3.GN Cuttings management system

Vertical cuttings dryer, decanter centrifuge and centrifuge pumps, as well as mud tank composed of this sub system. Since this tank are divided into two compartments too, we named it by No.3 compartment and No.4 compartment. After the mud was treated by vertical cuttings dryer, it will flow to No.3 compartment. And the clean mud will go to No.3 compartment from No. 2 compartment. The decanter centrifuge can separate particle size 5 microns, after this the clean mud can be re-used for drilling again.

How to maintain a GN Decanter Centrifuge?

Now many drilling industries and some other fields are using more and more decanter centrifuges due to the excellent performances of them. So it’s quite important for operators to know some repair knowledge to maintain the decanter centrifuge in a good condition.
As we all know, if we can take care of the decanter centrifuge carefully, and when we use it for working, follow the working principles strictly when it’s working.After using the decanter centrifuge, the workers do some regular maintenance according the operation manual. It’s sure the life ot decanter centrifuge can be prolonged and extended. In order to avoid any rust or dust to fall into the inner of the drilling centrifuge, workers should certainly mop the external of the machine to make sure it is dry and clean. Secondly, during our daily use, the decanter centrifuge’s conveyor and conveying belt are very easy to be loose , so it need to be frequently checked up and to be exchanged if they are do not work well. We should also check the easily wearing parts of the machine and the operating situation of the electric system of the machine and attach great importance to the battery system regularly.

We all know in order to have a very high level of concentricity between the Differential mechanism and the main body of the decanter centrifuge. We must be very careful when the decanter centrifuge machine is installed at the work site. To make sure and guarantee the necessary shaking when decanter centrifuge is operating, if the connection between the two parts of a machine, than a cooper chip should be put between the the conveying belt and differential mechanism.
Due to assorted reasons, the machine cannot work as well as the beginning, this phenomenon cannot be avoided. We will need to do an overhaul of the machine after some working time of a decanter centrifuge machine.
Aslo a good brand is vital important for our future maintenance and repairing. So welcome to ask for technical help from our technical engineer: thomas@gnsolidcontrol.com

Vertical Cuttings Dryers are generally used to reduce the amount cuttings discharge from water based mud (WBM), oil based mud (OBM) or synthetic based mud (SBM). Right now, as people pay much more attention to environment protection, the cuttings dryer are used more frequently. 
There’s another important reason, according to research, 1 to 4 barrels of clean drilling liquids can be also be recycled when 1 barrel of drill cuttings are separated by solids control equipment, which means using vertical cuttings dryer is very cost-effective in the long run.
Depend on different situation, we can choose a screw conveyor or a vacuum device to transport the drilling fluids to the vertical cuttings dryer. In the daily use, it’s quite common that a vertical cuttings dryer is equipped with a screw conveyor.
GN Vertical Cuttings Dryer uses centrifugal force to dry drilled solids from oil or synthetic base fluids. The drying efficiency can be reached to less than 5%

A: 1-shale shaker; 2-mud cleaner; 3-auger conveyor; 4-vertical cuttings dryer; 5-waste discharge;6- recovery of mud; 7- Collection Tank; 8-centrifuge feeding pump or screw pump; 9-centrifuge 10-solid discharge port; 11- Clean mud recovery mud system.
From the above picture, we can see clear about the workflow: Drilling mud from rig enter into shale shaker(1),mud cleaner(2).After treating by these two steps, the drilling cuttings enter into vertical cuttings dryer by auger conveyor(3). Solids enter the Vertical Cuttings Dryer (4) through the top feed inlet and are separated inside the Dryer. The clean solids exit the bottom of the Dryer and are discarded overboard (5) or collected in Cuttings Boxes for offsite transport and disposal. The recovered liquid is routed to a Liquid Collection Tank (7). The recovered liquid is conveyed by screw pump (8) and then processed through a decanting centrifuge (10) for final clarification, storage, and reuse (11).

The drilling fluids from vertical cuttings dryer contain a percentage of low gravity fine solids. Before the mud is discharged to the active system, it should be treated by a high speed centrifuge. However, this may not be necessary in all conditions. 

GN Solids Control just attended the Sixth CIPPE 2014 (from August 26th to August  28th )held in Shanghai. This year GN welcomed many old friends and recognized some new friends during this exhibition. And GN has attending this exhibition for several times.

As one of the most important part of Shale Shaker, the Shaker Screen are playing more and more important role in solids control. It’s now believed that a good shaker screen can separate sand & silt from the drilling fluids, and the shaker is much more important than the vibrator sometimes .

GN Shale Shaker Screen has variety types that can fulfill the demand of different brands shale shaker usage. For special shaker screen mesh, GN Shale Shaker Screen engineer can design and manufacture on customers’ demands.

Now GN Solids Control can provide the screens mesh from API 20 to API 400. Based on site experience, we would like to give you more introductions to our Pyramid Screens.

Compared with the flat plate screen, the pyramid screen has the following good characters:

1. Larger Shaker Capacity:
The total amount of usable API on-blanked screen area can increase by 105% when use pyramid screen on shale shaker. Fluids drilling management capacity will be more than 25%.
2. Better Permeability:
Due to corrugated screen’s trough, the working area is larger, so when the gravity and vibration forces the drilling solids into the screen, it allowing more fluid to pass through the top of the screen.
3. Drier Cuttings:
A more effective and faster drying capability will be occurred because of pyramid screens minimize fluid loss by dispersing thinner layers of fluid over an increased screen area.
4. Faster Fine Screen:
Utilizing Pyramid screen enable shakers to screen 2 to 3 mesh sizes finer than traditional perforated plate flat screen panels. This maximizes the solids removal efficiency of the shaker.
5. Maker Fine Separations:
Pyramid screens are capable of making separations as fine as 43 microns.
6. Fits Existing Shakers:
Pyramid screens fit all GN shale shakers and the other famous brands shale shakers, thus allowing for the most efficient use of existing equipment. There is no need to modify or replace existing equipment.

However, flat plate screen still has variety usage in today’s solids control filed. Sometimes, it’s more cost effective to use flat screen.Tha’s another thing we’re going to talk later.

Much more and more individuals are speaking about a zero discharge method for drilling rigs. Then, what is a zero discharge drilling mud system? In my opinion, it incorporates not merely the mud recycling program, but also the drilling waste management program. GN Solids America, as the leading manufacturer in both pointed out systems, can give zero discharge method.
Zero discharge technique right here offers two functions: in 1st step, drilling mud recycling method, drilling cuttings contained in mud are separated out, and clean mud returns to the drilling rig. 2ndly, drilling cuttings are collected and additional treated by waste management method, in which dryer cuttings are separated out. Sometimes, there is dewatering technique located right after the standard waste management.
A total GN Zero Discharge Program consists following sections:
1. GN Drilling Mud Recycling System, also regarded as solids control method. This configuration employs shale shaker tank- GNZS shale shakers, GNZCQ vacuum degasser, active tank-GNZJ desander & desilter and GNLW452 Decanter Centrifuge for separating weighted materials, mixing tank-GNSLS jet mud mixer, and storage tanks. All tanks are equipped with GNNJQ mud guns and GNJBQ mud agitators, and the pipelines and pumps are produced by GN Solids America also.
2. GN desilter method,GN Solids America is the 1st China solids control company who makes both high speed centrifuge GNLW363 and desilter,and desilter is tested in factory and jobsite, efficient for each WBM and OBM. GN Solids America also have High-G drying shaker GNZS594HGE available especially in waste management systems for WBM.
3. GN Dewatering Technique, right here we use 1 set of GNLW363 high speed decanter centrifuge and a flocculent unit.
In all, GN company is capable of providing the closed loop of zero discharge system for drilling rigs.
