Generally speaking , the shaker screen on the shaker will separate solids the that larger than it’s screen opening size and retain the drilling mud and smaller solids .When 50 percent of solids size being found in the underflow of the shaker screen and 50 percent of the solids of that size found in the over flow , that size is call D50 or 50% cut point . The cut point is a graphical representation of the actual measured separation of drilling solids made by the shaker screen . For example , a D20 cut point will be the size where 80% of the solids particalsiin that size that returned to the drilling mud through shaker screen and 20% of the size solids separated by shaker screen .

Shale Shaker for UAE

There are several reasons that may cause a shaker screen performance failure . Most of the failure result from the improper shaker screen installation or damage on the shale shaker . The crack or warp shaker bed may result from to long time of continuous use or improper maintenance which will cause poor vibration patterns . To achieve max screen life , all the tension bolts must be operating properly . If early screen failure occurs , please check and make sure that one or more of the tension bolts are not missing and keep sure they are tightened correctly as per manufacturers recommendation .

Another possible cause of the improper solids conveyance , and then , screen wear is the linear motion vibrators running in the same directions , which will cause an improper vibration pattern , the result in massive amounts of solids accumulating on the first screen ,causing them to wear quickly . This can easily be remedied by reversing the electric wiring to the motors and vibrators of the shale shaker should be tested before spudding the well .

While perform the drilling project on the earth, the rig produce the byproduct of cutting, crushing and grinding of solids that will be broken in loose pieces in different size. The size in industry standard is measure by micron. Solids control equipments in different filter stage will achieve the result by its design yet for muti-stage filter process, the line up of correct order of the machines are the must.
Mongoose Composite material screen 1
To make sure the drill hole cutting surface to the ground , the drilling fluid need to have enough speed in return. It depends on the well diameter and rig ability to decide the pump output volume to achieve the fluid speed. To achieve that speed, solids control machineries need to perform in specific purification level base on particle size and treating capacity are fact that need to be consider.
The choice of drilling fluid shaker screen

Shale shaker is filter the solids in drilling fluid and it is one of the primary equipment. The shale shaker filter the solids in various size by use the mesh that have different opening and layers to achieve the task. The mesh number of the screen is bigger, the smaller capacity to remove the solid size is smaller. The mesh number of is smaller, the bigger capacity to remove the solid size is larger.

In the drilling process, the mud pump produce large volume of mud that contain large cutting. The screen should use smaller mesh number to filter the cutting. Later in the drilling process while increase the depth and the well diameter is getting small, the pump produce the mud that contain smaller cutting, then it is time to use larger mesh number to filter smaller cutting. Other consideration such as mix ratio of water and solid will affect the result of filtering by the screen.

1. To make sure the operation of the shale shaker and normal usage life on screen, the operator need to make sure parts like wedges, screw cap bolt and springs on the shale shaker are installed correctly with no signs of wrongdoing. The operator installs the screens according the operation manual provide it from the seller.
2. To get full usage of the pre-tension shale shaker screen, operator need to ensure the rubber parts of the shale shaker is fully intact and show no sign of damage. Shale shaker screen is wear and tear parts and it will be needed for replacement after normal usage. If wear-down speed is faster than normal, then check all the moving parts of shale shaker is functioning properly and secure the screens correctly.

3. Lubrication and consist maintenance the shale shaker moving parts base on the operation manual is the must to ensure proper operation.
4. If the operator uses an OEM shale shaker screen that have not been pre-tension treatment, it is the must step that need to perform before usage.
5. If the drilling fluid flow out of the pore or damaged place, then cuttings can’t be removed. Any screen with holes or be damaged must be changed immediately, the hole and the damaged place can be sealed up by the panel. The screen must be changed as soon as possible, make a plan before the replacement to reduce the stopping drilling time, you should prepare the tools and screen before beginning to replace, if because the shale shaker is not operating, it will increase the cuttings content. It’s best to exchange the screen in a single period if possible. Need to stop the pump at the emergent time, stop drilling so as to replace the screen of shale shaker.
6. Any problem please fell free to contact us and learn to know our other products including mud agitator, decanter centrifuge, desander, mud tank ,drilling waste managent, drilling mud system etc.

GN Solids Control has established an American branch company in Houston, TX., which name is GN Solids America. By the establishment GN Solids America, GN shows his willingness to develop the America Market and to serve customers in the America better. And with the fast development of drilling and drilling rigs in Canada, GN must have a bright solids control equipments market there.Now these years, petrol companies in Canada have developing the whole year drilling period. And they tend to use this whole year drilling to replace the traditional drilling plans in Canada. Although, the drilling crews are not growing largely, the usage of drilling rigs are all have a high using frequency. The quantity of drilling especially the natural gas drillings are reaching a new records number, and the permitted drillings are increasing day by day.

The drilling activity in the west regions of Canada are getting more and more active. However, drillings in the west sea are not approved. It seems that Canadian drilling crews don’t need to be confined to the drilling restrictions like America has them on the mid-land. As we all know, the American council forbidden to drill on the side of Great Lakes, on the other side, Canada allow the drilling companies drill and extract natural gas and they can also make directional drilling to collect oil near Lake Inari.
According to an survey, Ontario has drilled 69 wells in 1999, 112 wells in 2000, 115 wells in 2001, 82 wells in 2002, 88 wells in 2003, 72 wells in 2004, 22 wells in June, 2005.

GN Catalogue
According to the statistics of BakerHughes, Canada has 509 rigs are in using until August 26th, this number is decreased by 26 than last week, but it is increased by 230 than the beginning of this year. During these using rigs, EnCana has 55 rigs that are in using, Canada Natural Resource and Devon both have 30 rigs.
Although these numbers are not quite near, we could also tell the great development of Canada market. This is not the best time for GN Solids Control, but it will never be the worst days for GN.

GN shale shaker is one of the main equipments in GN’s products line. It is widely used in all GN mud recycling systems for oil drilling and HDD. As a spare part of shale shaker, the shaker screen determines the shale shaker performance to some extend.

Wedge block to fasten the shaker screen

GN shale shaker screen is installed and removed by fastening and loosen the polyurethane wedge block. Fixing one pc screen need 2 pcs wedge blocks on either side of the shaker deck. The wedge block is wedged into the slot produced by a piece welded angle stell.
When replace the shaker screen, just need loosen the wedge blocks. It is bery easy and time saving which greatly increase the working efficience.

GN Shaker Rubber Gaskets for Screen Protection


Rubber gaskets to protect the shaker screen

When operating the shale shaker, the high G vibration force produced by the vibration motor also make the screen shake up and down. In order to reduce the shakeing force functioned on the screen, we stick rubber strip on the screen frame. Besides this, GN Shale shaker also has the screen supporting steel beam according the screen frame as well as the rubber gaskets on the shaker deck. All above has greatly increase the impact resistance of the shaker screen and extended the screen life.

The above mentioned shale shaker screen installation design features all source from our customer’s feedback, that is why GN could keep growing and win more and more trust from customer. If you want to learn more about GN Solids Control equipments, welcome contact with us.
