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

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 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

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

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.

GN solids control choose Italy Oli brand vibrating motor for all our shale shakers. Vibration motor is important components for shale shaker, I will introduce briefly about vibrating motor installation & maintenance.

1 How to install vibrating motor ?

shale shaker vibrator

shale shaker vibrator

 (1). Before installing vibrator, turn off and lock out/tag out all energy sources to mounting structure according to ANSI standards。

(2). If using a cutting torch or welding, test atmosphere for gas level or dust content.

(3). Make sure mounting surface is strong and flat, 0.25 mm acros vibrator feet. (This will minimize internal stress to vibrator casting when tightening mount bolts.

(4) Make sure mounting surface and vibrator are clean and free of debris, paint, and oxidation.

(5) Before installing vibrator onto mount, apply thread sealing compound to all bolts.

(6) After the vibrator has been operated for 10 to 20 minutes, check bolt torque. Tighten if necessary

2 How to  maintain  vibrating motor?

(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℃

During running, every 2000 working hours user should makeup LGHP2 lubricate grease once. Every bearing can not be filled over 25.8g.

GNZS703 shale shaker is widely used for oil and gas drilling and directional drilling in the world.

1 shaker deck adjustment

LMSS
LMSS

A spring-loaded plunger and reversible pawl provide a ratcheting action during movement of the operating handle. A full 180 degrees of movement is possible in both directions. Depending on pawl setting, moving the handle in one direction turns the jack screw to raise or lower the screen frame, while in the other direction the jack screw remains stationary during handle movement. The spring-loaded pawl permits the operator to switch the direction to either raise or lower the screen frame, as required.The angle of the discharge end of the screen frame is infinitely adjustable within the equipment’s available range.

2 shale shaker maintenance

(1)Inspect discharge duct connection on side of hopper for leaks. Tighten connection and/or add silicone sealant to prevent leakage.

(2)Inspect cover on unused hopper discharge connection for leaks. Tighten connection and/or add silicone sealant to prevent leakage.

(3)Using a water hose, wash off accumulated process material from screen frame, interior of hopper and AWD angle adjustment components.

(4)Excess process material in these areas may impede angle adjustment of screen frame and can reduce screen frame vibration if the frame bottoms out on the buildup.

(5)Check for and remove any accumulation of process material or other obstruction in feeder interior. Feeder blockage may cause excessive splashing and uneven distribution of slurry onto the screen bed.
