Drilling Fluids shale shaker

Shale shaker and Mud cleaner is the basic separation equipment in drilling mud solids control system. Shale shaker is the 1st stage solids control equipment. It is 1st separation equipment to treat the dirt drilling mud from drill holes. Drilling mud cleaner is used after solids control shale shaker. It is the 2nd and / or 3rd solids control separation equipment.

A set of dual tandem shale shaker and mud cleaner package is ready and will be shipped to a drilling company. Dual tandem shale shaker is widely used at work over rig drilling mud recycling system. The dual tandem shale shaker shipped in this project is a combination of Qty 2 GNZS594F-SHBF shale shaker, a mounting skid, and mud distribution pipelines. All of them have 2 motors on each shale shakers.totally 4 motors for a set dual tandem shale shaker package. GNZS594F-SHBF is the model of single shale shaker. It is a single deck linear motion shale shaker.

GNZS594 is the series code of the shaker model. It means the shaker screen width is 590mm. 4 means 4-panel shale shaker. F is the version of the shale shaker. S means solids control shale shaker. GN Solids Control also offers HG (high G drying) shaker for drilling cuttings management. HB means the shale shaker is equipment with back type mud distribution box. F is the design version of the shale shaker.

The mud cleaner in this system is a 1000GPM combo type 3-1 shale shaker. The model of the combo type mud cleaner is GNZJ594F-S2S12NF. It is a combination of Qty 1 solids control shale shaker GNZS594F, Qty 2 × 10 inch desander cone, and Qty 12 × 4 inch desilter cone. The under flow shale shaker model is GNZS594F. In this case, all spare parts are interchangeable with the first step solids control shale shaker. Clients are easy to stock back up spare parts and replacement shaker screens.

Chinese Lunar New Year holiday is coming in Feb. There weeks, all workshops of GN Solids Control are works with more shifts in order to finish all orders before the big holiday. A full package drilling mud solids control system will be ready soon and dispatch to sea port next week to catch the vessel.

The full package solid control system is designed and made for a European client. The client cooperated with GN Solids Control for many years. It is not the 1rst mud system the clients bought from GN. They have many similar size drilling mud system from GN Solids Control.

Below is the major equipment list of the full package drilling mud solids control system:

1) Shale Shaker. It is the 1rst stage solids control equipment for drilling mud system, and it is the major separation equipment in a drilling mud treatment system. There are 2 sets linear motion shale shaker in the mud system. Some clients will order an extra shale shaker as backup. The shale shaker model is GNZS594F. It is a 4-panel shale shaker. And it is the most hot sale shaker model from GN Solids Control.

2) Mud cleaner. It is normally 1 mud cleaner in a full package mud cleaning system. And in some jobsite, clients will use more shale shaker to replace mud cleaner. It is also called as 3-in-1 cleaner. It is the combination of a shale shaker, desander separator and desilter separator.

3) Lower/middle speed Decanter centrifuge. The model is GNLW452D. It is a 18inch bowl size middle speed centrifuge which is used for barite recovering.

4) High speed decanter centrifuge. After low speed centrifuge, there is a high speed centrifuge GNLW363C in the system for fine solids separation. As after some circulations, there will be more and more ultra fine solids inside the drilling mud, the drilling mud is weighted. High speed centrifuge will be used in this condition to reduce the mud weight.

5) Centrifugal pump. There are 6 centrifugal pumps inside the system for different functions: a desander feed pump, a desilter feed pump, 2 mixing pumps, and supercharging pump for drilling rig mud pump.

GN Solids Control is focusing on the full package of drilling mud processing system. As GN Solids Control makes full line drilling mud processing equipment. They know well about the equipment. GN Solids Control can offer professional proposal of drilling mud treatment system and mud mixing unit. All processing equipment and the tank volume should be match to each other.

For example, if the total shale capacity is max. 160m3/4 or 200m3/h, but the desilter and desilter capacity is 240m3/h. And feeding centrifugal pump and mixing pump are 55kw or above. The system is not reasonable. As the 1rst stage separation equipment, the shale shaker capacity should be bigger than the next step separation equipment. Otherwise, if the mud flow is big, the shale shaker will overflow. Or if the mud flow is small for the shale shaker to handle, but the desander and desilter pump are too big, it will cause pump suction air. And the hydrocyclone separation performance is not good in condition the feed flow is too small. The client need to increase shale shaker capacity, or decrease pump and mud cleaner capacity to suit for the mud pump capacity.

Every jobsite is different. Every client has his preferable. In order to offer a suitable mud system design to suit for the job site situation, as well as client’s special requirements. Below are some questions to let GN Solids Control knows more about clients request.

1) what is the rig horse power of the system for, or what is the mud pump horse power or capacity? The whole mud system handle capacity should suit to the mud pump capacity.
2) What is the total tank volume the client prefer?
3) How many tanks the client prefer?
4) What is the max. Tank size (L × W × H) the client can accept to suit for their local shipping regulations?
5) What processing equipment they prefer to equip inside the system? Shale shaker, mud cleaner, desilter, desilter, mud cleaner, vacuum degasser, decanter centrifuge, etc..Which processing equipment they want?
6) What is the Voltage and hz for the mud system?
7) What is the explosion proof standard, CNEX, ATEX, or international IECEx standard?
8) Additional requirement and any special requirements if there, like do they want trip tank, pill tank, water tank, etc…

GN Solids Control makes full line drilling mud solids control equipment and drilling waste management equipment. GN Solids Control is also capacity to make high quality replacement shaker screens. Besides makes replacement shaker screens for GN Solids Control own brand shale shaker and mud cleaner. GN Solids Control is also a famous screen manufacturer for various models and brands shale shaker.

GN Solids Control makes high quality composite frame pretension screen. The screen internal is supported with metal frame for reinforce. The screen external are covered by special material plastic which contains fiber glass for durable at high temperature. The external plastic is made from hot press by hot press machine. Compared with traditional metal frame, it is more environment friendly during manufacturing. And the quality is much more stable and under control. As the traditional metal frame frame cover plastic by dipping, which causes more pollution. And more man power involved during manufacturing. The quality is not stable at automatic machine production line.

Some clients may think composite frame shaker screen is an excellent screen on quality and performance, but they are not environmental friendly and a high carbon foot print for decades to come. They prefer the company to make the decision to revert back to metal frame screens to as a commitment to the environment and to reduce carbon foot print . They think Metal frame screen platform can be recycled for other manufacturing applications.

It is good question. When people talk about plastic, it may mean pollution. But this plastic which GN Solids Control use to make screens is PP (polypropylene). It is (C3H6)n only have C and H to produce CO2 and H2O if burning. This PP (polypropylene) plastic is relatively less environmental impact. And In many countries like in China, there are some companies who can do the recycling of the composite frames made by PP (polypropylene) and metal.

GN Solids Control made a small liquid and solids separation system. The small system is customized for an Europe company per clients request. The client asked for a small recycling unit with cleaning capacity of about 12-15 m³ / hour. The client wants a small single centrifuge in the small recycling system.

GN Solids Control customized a compact system which is composed of a small size shale shaker and a mini size decanter centrifuge. The shale shaker and decanter centrifuge are located on a mud tank together with a centrifuge feeding pump and electric control cabinet for the whole system. Tank size for the whole system is 3900Lx2250Wx1300H (mm) for easy movement. It is a small capacity recycling system with turn-key solution. All connections inside the system are included.

The Shale shaker separator model is GNZS752F-MDZF. It is a 2-panel small size shale shaker with small footprint.

The Decanter centrifuge model is GNLW223D-VFD. It is a 9” baby centrifuge for fine solids separation. The Cut point of GNLW223D-VFD centrifuge is 2 ~ 5 microns.

The color, brand and logo are all customized per client’s request. GN Solids Control is capable to make other customized system per clients job site situation. Clients can contact GN Solids Control sales engineer to get customized solutions.

Shale shaker model GNZS594F is designed and made by GN Solids Control to treat drilling mud for oil and gas drilling, HDD, TBM, CBM and other drilling activities. It is a linear motion shale shaker.

GN Solids Control keeps optimizing the product design and material base on jobsite performance. GNZS594F is the 6th generation shale shaker from GN Solids Control. It is the latest shale shaker model from GN Solids Control. It avoids most problems happened before and add some additional features per clients’ demands to make the shale shaker more durable and more user friendly.

GNZS594F shale shaker uses the same shaker screen with Mongoose shaker. GN Solids Control also makes mud cleaner with the same under flow shale shaker GNZS594F. The hydra cyclone unit on top of the shaker deck is easy to be removed. Once remove the desander and destiler cone unit, the mud cleaner can be used as a separated shale shaker.

Compared with other brand shale shakers, GN Solids Control shale shaker owns significant advantages:
1) GN GNZS594F shale shaker is utilizing composite frame pretension shaker screen, its life time is longer than traditional metal frame shaker screen and hoop type shaker screen. And composite frame screen usable area and screen conductance is better than traditional metal frame screens.
2) GN GNZS594F shale shaker and mud cleaner is fixing shaker screens by wedges. Compared with fixing screens by bolts, wedges is a very much and easy way for screen changing.
3) The GN shaker bed below the shaker screen is made from stainless steel to have anti-corrosion features for longer life. And the whole shaker deck is after heat treatment for more durable.
4) GN Solids Control shaker deck is sealed by oil-resistant sealing rubbers. It is GN patent design. And the shaker deck sealing rubber is interchangeable. The patent shaker screen seal technology can avoid fine solids bypass, and it makes the shale shaker deck easy for maintenance.
5) Mechanical Deck angle adjustable while working system to work reliably for different drilling fluids

Some sets of 500GPM mud desander plant will be ready for shipment in the coming week. They are ordered by a China domestic client for their trenchless drilling machines. The mode of these 500GPM mud desander plant is GNMS-500D. It is a very compact desandind plant to treat drilling mud from trenchless drilling well. The GNMS-500D desanding plants are customized with clients color and brand.

There is a double deck mud cleaner used in the system. The dirt drilling mud from trenchless well will be fed to the bottom deck of the double deck desander mud cleaner. As there are high sand contend and even rocks from the trenchless drilling well, PU screens or metal frame screen with bigger screen opening will be used for the bottom deck for screen separation. After the screening separation, the rocks and sands bigger than the screen opening will be 100% removed from the system, the liquid phase will pass the screen and fall down to the mud tank.

A centrifugal pump on the tank slop will suck and transfer the shale shaker recovered drilling mud to the 10’’ desander hydrau cyclone for desanding separation. The cuttings point of 10’’ desander hydrau cyclone is 57 microns. The clean drilling mud separated from 10’’ desander hydrau cyclone will flow to trenchless drilling rig well, or goes to storage tank. Hydrau cyclone is not a 100% separation device, there will be some percentage of usable clean mud be discharged together with sands.

As the 10’’ desander hydrau cyclone unit is mounted on top of the double deck shale shaker. The discharged dirty mud will be separated again by the upper deck screens to further recovery the usable drilling fluids. There are pressure while the dirty mud discharged from 10’’ desander hydrau cyclone, if they falls down to the screen surface directly, the mud will damage the shaker screens very soon. In order to protection screen and extend the life time. GN Solids Control equips small hopper under the 10’’ desander hydrau cyclone for damping.

Recently, a mud cleaning shale shaker, mud cleaner, and decanter centrifuge started to work at an Environmental Protection Company in U.S.A. The Environmental Protection Company in U.S.A. is to collect waste water and waste slurry from different activities, like from drilling, from construction job sites, etc… The company will treat the waste slurry, and cover the water and oil for reuse or resell. The recovered solids, cuttings and particles can be sold again to construction company for building construction, or to build roads.

Below separation equipment in included in the mud cleaning job site for the USA Environmental Protection Company.
The 1st mud cleaning equipment is a Shale Shaker. It is a 4-panel shale shaker utilizing composite material pretension shaker screen. The shale shaker model is GNZS594-HB. It is the most hot sale shale shaker model from GN Solids Control. The shale shaker is widely used in oil and gas drilling, non-oil drilling, and waste slurry separation.

The 2nd stage separation equipment is a 3-in-1 mud cleaner. The mud cleaner model is GNZJ594-2S12N. The 3-in-1 mud cleaner separator is combined of a shale shaker, above the shale shaker, there is a package of desander cone, and a package of desilter cone. The desander and desilter packing are used on top of the under flow shale shaker. The recovered slurry from desander and desilter falls down to the under flow shale shaker, and recovered by the shaker screens which with fine wire mesh. The desander separation is 10 inch which is with cut point 47 microns. The slurry recovered from desander separator will be pumped to desilter separation. The cut point of desilter separator is 27 microns, which is used to further purify the recovered slurry. After desilter separator, the weight of the slurry can be reduced, the solids content is smaller. And the solids size in the slurry is qualified for high speed decanter centrifuge separation.

A high speed big bowl decanter centrifuge GNLW553-VFD is used after mud cleaner separator to remove the ultrafine solids up to 2 microns.

Dual motion shale shaker is a kind of solids control drilling mud processing equipment. Shale shaker is the 1st stage solids control equipment to pre-treat drilling mud from drilling rigs. GNZS594F-SHBF is a Single Deck Dual Motion Shale Shaker. The shale shaker can be equipment with top weir feeder, or with back weir feeder.

GNZS594F-SHBF is a Dual Motion Shale Shaker. The shale shaker can work as Linear motion or Gradual elliptical motion. The working principle of dual motion is as below.

1) There are two vibrator motors mounted on the shale shaker, one of the vibrator motor can be adjusted manually. If the eccentricity is set to the eccentricity ratio we need, the forward and reverse excitation force of this vibrator will not change; the other’s eccentricity cannot be adjusted manually. The eccentricity ratio of forward and reverse is informed to the supplier in advance. The excitation force of this vibrator during forward rotation is exactly the same with the first one while it is only half of the first one when reverse rotating.

Generally speaking, the linear track motion is the opposite rotation of two vibrator motors; the gradual track motion is the same direction rotation of two vibrator motors.

When switching the two motion tracks at drilling site, it is necessary to wait until the shale shaker is completely stationary before switching through the button of the electric control panel. Before delivery from manufacture’s factory, the electric control cabinets will be equipped with function of shifting between dual motion shale shaker control and linear motion shale shaker control. The shale shkaker that has been delivered can realize track switching by adjusting the eccentric position and rotation direction of a vibrator.

Besides dual motion shale shaker, GN Solids Control can make linear motion shale shaker, mud cleaner, desander, desilter, decanter centrifuge and other solids control equipment.
