On oil drilling rig site, Hi-G dryer shaker and double deck shaker is widely used for drilling cuttings treatment and recycling. They are both linear motion shale shaker. Some customer do not know the difference of Double deck shale shaker and High-G dryer shaker. As world top solids control and waste management equipment manufacturer, GN Solids can tell you the difference of the 2 types of shale shaker and choose the suitable model for your drilling rig.

Hi-G Dryer Shaker ( recommended model GNZS594, linear motion)

Compared with traditional shale shaker, this model with a Higher G force, can get better vibration screen separation. This model with 4 panel Mongoose shaker screen, can get bigger treating capacity. And the shaker screen is interchangeable with Swaco Mongoose screen, you can get the shaker screen from local Swaco distributor easily.

As it is single deck, relative easy to change shaker screen compared with double deck shale shaker.

Simply speaking, mud cleaner is shale shaker, desander, desilter assy, it is also called 3 in 1. GNZJ703 & GNZJ853 is the best choice for large treating capacity, large screen area mud cleaner, most of our clients use GN made mud cleaner before GN decanter centrifuge, this action can improve the performance of GN decanting centrifuge.

Mud cleaner maintenance including

1 vibration motor maintenance

(1)Clean dust on shell regularly

(2)Before operating, must check the bolts to confirm whether there is loose or not. Otherwise, we must screw bolts tight before running shaker

(3)Inspect the cable, whether there is wear, hold down, crushing, etc.

(4)the vibration motor should be under good lubrication during operation:

Motors before fixed on shaker, the bearing is filled with SKF specific lubricate grease, the temperature range is -40 ~ 200℃

2 shaker screen maintenance

(1)Before every shut off, the shaker should run without any load for 5-10 minutes, at the same time, use clean water to flush screen clean

(2)Every time finish operation, the shaker frame and screen should be flushed by water. Pls replace new screen or repair the damaged screen once it is found damage, otherwise large cutting may dropped into the clean mud and influence the following process.

3 Electric cabinet maintenance

Simply speaking, mud cleaner is desander, desilter, shale shaker 3 in 1, sometimes people called it 3 in 1. For a four phase cleaning solids control system, mud cleaner can do the job for 2nd and 3rdphase cleaning of drilling fluids.

GN mud cleaner features:

1 standard design with various treating capacity, 500gpm, 1000gpm, 1500gpm

2 large shaker screen area to dry the solids and recycle more fluids

3 compact footprint, container shipping suitable

4 Easy maintenance, stainless steel valve on each hydrocyclone can make the replacement of cone easier, you do not need to stop whole machine.

MI-SWACO mud cleaner features:

Designed to handle the entire circulating volume to remove and dry solids while retaining premium base fluid. They are equally effective for both weighted and unweighted drilling-fluids.The hydrocyclones make the primary separation with underflow directed onto the shaker vibrating screen.

The drilling fluids with the cuttings from the well are discharged to a rig shale shaker where the cuttings are separated from the drilling fluid. The separation step does not completely remove drilling fluid from the cuttings, some drilling fluid and additives remain on the drill cuttings.

drilling cutting treatment equipments

Then such drilling cuttings with drilling fluids will be dropped into a GN drilling waste system, through physical way to separate the usable drilling fluids with unusable drilling cuttings. For example, hi-G shale shaker to separate larger drilling cuttings, then verti-cutting dryer to separate drilling cuttings with oil less than 5%.The usable drilling fluids are treated by decanter centrifuge, then clean drilling fluids and water will back to rig again.

The cuttings separated by verti-cutting dryer with less than 5% oil can not be drain off directly, it may pollute the environment. We must use chemical way to continue the treatment.

Drilling cuttings treatment method:

Thermal desorption, re-injection, incineration and solidification.These methods have been applied in the site, they may have their own advantages and disadvantages.

Thermal desorption:

use of the patented Porcupine Processor to remove all water and oil, leaving a residual total petroleum hydrocarbon on cuttings of less than 1%.

Re-injection :

GN new products hi-G dryer GNZS85-3 is designed to replace the old model hi-G dryer GNZS63-4. GN Hi-G dryer shaker is with long shaker deck big capacity which is used for waste management to treat the drilling cuttings from the primary solids control equipments, like shale shaker, desander, desilter to dry the solids for transportation, and make the fluids easier for future treatment. To know more info of primary solids control equipments, pls check GN website.

GN hi-G dryer

GN hi-G dryer

What is the features of GNZS853 compared with GNZS63-4?

1 Even it is 3 –panel hi-G dryer, its screen area is larger than 4-panel hi-G dryer. The larger the screen area is, the dryer the cutting is. Total deck screen length is 2550mm, the total deck screen length of GNZS63-4 is 2520mm. Total screen area of GNZS85-3 is 3.2m2, but the total screen area of GNZS63-4 is only 3.15m2. And GNZS85-3’s screen area and total deck length is larger than Derrick 4-panle shale shaker/mud cleaner.

So 4-panel shaker is not must be better than 3-panel shaker.

2 3-panel shaker screen can enlarge the effective screen area, the waste screen area is less compared with 4 screen panel. It can improve the performance of hi-G dryer.

3 Mechanical deck adjustable while operation for reliable performance.

GN solids control developed a new product- mini shale shaker, model GNZS752. It can meet the requirement for the clients who do not need so large treating capacity, but want to find an economic way to separate big solids from the drilling fluids.

mini shale shaker

GNZS752 shale shaker with unit treating capacity 264gpm, 2 screen panels with total screen area 1.35m2, G-force 6.3G adjustable, total power of this shaker is only 1.0KW, and total weight 800 kgs. Based on these parameters, we called it mini shale shaker.

This linear motion shale shaker GNZS752 can be widely used in HDD, water well drilling , shadow drilling and other drillings which need small treating capacity. After the new mini shaker is developed, there are many clients showed their interests. Before they have to use bigger shaker 2-panel GNZS852 or even 3-panel GNZS703. These shakers can treat the drilling mud better because of their large treating capacity, but it is a waste of money.

Comparison between GNZS752 and Brandt mini Cobra 2-panel shaker

Motor power: Brandt mini Cobra is 1.1KW x 2 , GN mini shaker is 0.5KW x 2

Screen area: Brandt mini Cobra is 1.6m2, GN mini shaker is 1.35m2

Screen panel: Both of them are 2 panel

Screen type: pretension, repairable

Many clients asked us this question, how to revert API To Micron for Shaker screen mesh,even most of shaker screens manufactures in China do not have this knowledge. Some manufacturers use the API number as mesh directly, this will be incorrect, if clients do not have professional knowledge, they will use the wrong mesh screens and can not get the ideal result.

Here we will introduce how to revert API To Micron for Shaker screen.

Vibrating screen normally called shale shaker in oil and gas drilling industry. GN solids control produce vibrating screen machine and replacement screens for it.

Working principle of vibrating screen:

GN vibrating screen

GN vibrating screen

By the motor force and adjusting the amplitude of the eccentric shaft, vibrating screen moves quickly like a circle. Materials in the sieve case can be saperated and screened from the sieve pore in this process.

Vibrating screen in Venezuela

We are seeking for a distributor in Venezuela to have some of our shaker screens in stock, the local market’s requirement is very large. If you are interested in GN distributor in Venezuela, and have large enough warehouse and good client’s network, pls contact GN solids control.

GN vibrating screen model:

By treating capacity:

80m3/h, 120m3/h, 150m3/h, 200m3/h

By vibration motion:

Linear motion and balanced elliptical motion

By screen panel qty

2-screen-panel, 3-panels, 4-panels
