 GN shale shaker Shale shaker is one type major solids control equipment used in oilfield drilling, HDD or other drilling projects. Nowadays, the most advantaged shale shaker is the balanced elliptical shale shaker, while the most popular used is the linear motion shale shaker. What is the difference between the linear motion and balanced elliptical shale shaker. Let’s talk something about it.
As we known, the second generation shale shaker is Elliptical motion, the third generation is linear motion and the fourth generation is balanced elliptical motion. Many clients often regard the fourth generation as elliptical motion, however, that is an incorrect understading about it. Please refer the pictures below, you could find the difference of these two vibration mode:
 Linear Motion Linear motion shale shaker often apply 2 vibrating motor with same power, but the vibrating direction is opposit horizontal. At the vertical direction, the vibrating force produced by 2 motors will reduplicate. Thus the vibrationg mode is a linear and forward direction.
While on a Balanced elliptical shale shaker, the 2 vibrating motors are different in power, that results an unbalanced force counteracting. So the vibration mode will be like that (shown in below picture.)
 Balanced Elliptical Motion
The balanced elliptical shale shaker is a production from combination of commerce and science. GN BEM shaker won the National technology progress awards.
By now, we have exported many sets BEM shale shaker to our customers, if you want learn more about shale shaker or need a quote, just feel free to contact with us.

Cellar Pump, we could also call it submersible slurry pump, mud guzzler, trash pump etc. How should we call it all depends on where we are in the world. Cellar pump plaies an important role in HDD mud cleaning system. Today, let’s talk something about it.
 cellar pump
Location and Application of Cellar Pump
In a HDD (Horizontal Directional Drilling) project, the drilling mud overflowing from the drill hole is often guided into a mud pit or a lower tank which the drilling mud level is lower than the drilling mud cleaning equipments. Therefore, we need a device to transfer the mud from a lower place to a relative higher place, that is why we choose cellar pump. Cellar pump is used to transfer the drilling mud to the first stage mud cleaning equipment – shale shaker. To some extend, cellar pump is not one part of the complete mud cleaning system. It is a medium between the rig and mud system.

In order to learn well about Trenchless Drilling Mud System, we have to know what is trenchless drilling technology. Trenchless technology is a type of subsurface construction work that requires few trenches or no continuous trenches. Because of the minimal disruption to surface traffic, business, and other activities, trenchless drilling technology is widely used in installation of new or replacement or rehabilitation of existing underground infrastructure.

Why Need A Mud System in Trenchless Drilling
HDD is a well known type of trenchless drilling, in the drilling project, we will need the horizontal directional drilling rig. In order to protect the rig bit and make it easy for drilling, a good number of drilling mud will be used. Therefore, the need for mud system is emerged. During a large treating capacity trenchless drilling project, mud system is only partial unit of it. We can also find drill rig, mud pump and other equipments. Continue reading »

GN 500 GPM mud recycling system is a very popular system used in HDD and CBM drilling. Unlike other solids control equipments supplier who mainly foucs their attenction on oilfield , GN meanwhile also devote herself to the development of compact mud system in HDD and CBM drilling project. Under this condition, GN 500 GPM mud system emerges as the times require.
By now, The largest HDD contractor: China petroleum Pipeline Bureau(CPP) have bought more than 25 sets GN 500 GPM mud recycling system from us.
 GN standard 500GPM mud recycling system equipments list:
1. 2 sets GNPS 70-3 balanced elliptical motion Shale Shaker;
2. 1 set GNPJ 70-3 Mud Cleaner with 1 each 10″ desilter cyclong and 8 each 4″ desander cyclone;
3. 2 sets SB5x4-14 Centrifugal Pump, one for desander and the other one for desilter;
4. 1 set JBQ7.5 Mud Agitator with 7.5 kw motor;
5. 1 set 3″ Mud Gun;
6. 1 set SLH150-35 Jet Mud Mixer matched with SB5x4-14 mud mixing pump;
7. Pedestal recycling tank, Electric control system and attachments like ladder, hanarail and lightings. Continue reading »

If you are looking for desanding equipment for micro-tunneling, horizontal Directional Drilling(HDD), water well and environmental vertical drilling or rotary drilling, slurry separation system, etc underground construction applications, GN desanding equipments are your best choice.
 desanding equipment GN Desanding system including the following equipments. 1 Desander with 10 inch polyurethane hydrocyclone( 2 pcs or 1 pc, depends on the required treatment capacity of the end-user)
2 Desilter with 4 inch polyurethane cone( 8~12pcs)
We can offer the desander and desilter with two types, with underflow shaker or without. Some client need the underflow shaker to collect the treated mud by hydrocyclones, so the clean mud will not be wasted. That is why many clients use high mesh desander/desilter screen so it can separate slight particles.
If the cones numbers exceed 16pcs, it is better to use a large underflow shaker, such as GNZS63-3 shaker, GNZS83-2 shaker, otherwise it will lead to overflow, because the treating capacity of cones are rising, but the flow rate of shaker is not large enough, even it use a high mesh screen.
3 Horizontal or vertical centrifugal pumps feed for desander and desilter.
4 Mud tank with electric control panel

Horizontal Directionally Drilling (HDD) has proven itself over the last few years to be a very effective technique for the installation of pipelines and other utilities in sensitive or congested areas.
 HDD mud recycling and mixing system Gone are the days when the only option was to tear up the asphalt to lay new underground water, cable, and electric lines in developed areas. Now horizontal directional drilling (also known as trenchless technology and directional boring) goes under roads, driveways, wetlands, and other natural and man-made structures.

GN drilling fluids recycling unit is a new developed system for HDD client.
Drilling fluids recycling unit have found favor with the mid-size rig contractors and are even being used with some mini-rigs today. Advantages such as cleaner locations, less water hauled in and less mud hauled off, less drilling fluid products required to complete the bore, and reduction in labor cost and drilling time are now being had by contractors throughout the industry.
Main Benefits of GN drilling fluids recycling unit
- Cost effective method of re-cycling drilling muds.
- Reduces cost of supplying fresh mud.
- Avoids cost of disposing of liquid waste.
- leaving the useful bentonite particles in suspension for re-use.
- The discharge from the cleaner is virtually dry, dramatically reducing disposal costs.
- Reliable and durable design, based on 20 years of field experience Engineer
