API SHAKER SCREEN

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.

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.

Final week, a single unique one of a kind of GN Solids Manage purchasers has purchased from GN Solids Manage two sets of Vacuum Degasser GNZCQ270A to Middle East. Initially, he intended to get a planet well known brand from a US solids manage enterprise, with model FLO-1200. But he in the end chose GNZCQ270A, not merely as a result of the larger cost-effectiveness, but in addition on account of the distinctive and monetary functions GN Vacuum Degassers have.

Comparing with other brands vacuum degassers, GNZCQ series Vacuum Degassers have following characters:
1. GNZCQ vacuum degasser is commonly a self contained device, which can suck the mud by itself, with no the have to have of employing a further larger power centrifugal pump. As is recognized to all, centrifugal pumps are continually utilised for feeding equipments inside a solids handle method which consume the largest volume of energy. This exclusive style assists user to minimize the operating expense.
two. GNZCQ vacuum degasser was equipped having a level sensor to monitor the liquid level in it, as a way to safeguard the vacuum degasser inside the course of operate
three. GNZCQ was created and developed getting a regenerative vacuum. It really is employed to draw gas-cut mud in to the degasser. That explained why there is not any need to have with the centrifugal pump. And within this way, vacuum degasser might pretty well be regarded as a significant agitator.
May possibly possibly most likely you’ve got got any interest in Vacuum Degasser or other solids handle facilities for oil & gas field, please contact me freely.

If a shaker has many screens (1 over the top of a further), separation is determined by the finest, or bottom screen. The coarsest screen need to constantly be the prime screen. It really is crucial that the bottom screen be checked typically for tears. (See operational suggestions in the finish of this section.)
If a shaker screen has multiple screens in series or if parallel shakers are utilized, separation is determined by the coarsest screen. Shakers in parallel should really use the very same mesh screens. (See operational suggestions at the finish of this section.
Gumbo poses significant problems for screening devices such as shale shakers. Gumbo in a water base mud tends to stick for the screen and is difficult to convey off the screen. Gumbo will not convey out of a pool of liquid and most “high-performance” screening machines will have to become tilted down to enhance the conveyance. The shaker screen ought to be cleaned and initially tilted downhill to 15 degrees, flow ought to then be fed to the unit. The deck angle should really be tilted downhill until the gumbo moves continuously from the feed till it discharges over the finish of the unit. A modify in screen mesh may possibly be required. Some rigs have-devices, referred to as “gumbo busters”, constructed into their flowlines to get rid of the gumbo. To lessen solids loading effects and also the effect of gumbo, a “scalping” shaker or rotating belt which include Derrick’s Flo-LineTm Scalper could be utilized. The scalping shaker will not have to be a high functionality shaker and should really be run with eight to 10 mesh screens. Running finer screens on this shaker will generally demand far more than one particular scalping shaker to meet screen area demands for fluid throughput. Other devices which use a non-vibrating rotating mesh belt, such as Derrick’s Flo-Line Scalper, are useful in removing gumbo ahead of higher functionality shakers.
