The shale shakers performance can be easily observed, all aspects of its operation are visible. Shale shakers provide the advantage of not degrading soft or friable cuttings. When well operated and maintained,shale shakers can produce a relatively dry cuttings discharge.
In unweighted muds, the shale shaker’s main role is to remove as much solids as possible and reduce the solids loading to the downstream hydrocyclones and centrifuges to improve their efficiency. In muds containing solid weighting agents such as barite, the shale shaker is the primary solids removal device. It is usually relied upon to remove all drilled cuttings coarser than the weighting material. Downstream equipment will often remove too much valuable weighting material.Enough shakers should be installed to process the entire circulating rate with the goal of removing as many drilled cuttings as economically feasible. Given the importance of the shale shaker, the most efficient
shakers and screens should be selected to achieve optimum economic performance of the solids control system.
Shaker performance is a function of:
- Vibration pattern
- Vibration dynamics
- Deck size and configuration
- Shaker screen characteristics
- Mud rheology (plastic viscosity)
- Solids loading rate (penetration rate, hole diameter)
The impact of each is discussed in detail in this chapter. Guidelines for shaker and screen selection are also provided.Simply stated, a shale shaker works by channelling mud and solids onto vibrating screens. The mud and fine solids pass through the screens and return to the active system. Solids coarser than the screen openings are conveyed off the screen by the vibratory motion of the shaker. The shaker is the only solids removal device that makes a separation based on physical particle size. Hydrocyclones and centrifuges separate solids based on differences in their relative mass.

The applicable range of drilling fluid vibrating screen:
Ground / offshore oil / gas drilling / CBM excavation / Trenchless Directional Crossing / piling / waste water / mud treatment etc., primary and two or three stage solids handling of mud and liquid to be treated. mostly, it is the primary treatment of mud and solid liquid mixtures applicable to various environments.
Function
The performance can be expected and operation direct to watch . Shale shakers provide the advantage of not,easy manage and maintain,shale shakers can produce a sure dry cuttings discharge.equipment’s main job is remove as much solids as possible and reduce the solids loading to the next level, the shale shaker is the primary solids removal device. It is usually relied upon to remove all drilled cuttings coarser than the weighting material. Downstream equipment will often remove too much valuable weighting
Numbers shaker should be installed to process the whole circulating with the target of removing as much drilled cuttings as economically feasible. because as the important part of the system, need arrange enough quantity shale shaker and put at suitable place to achieve optimum economic performance of the solids control system.
The working principle
mainly by the screen frame, screen exciter, damping element composed of drilling fluid shaker, by the mechanical vibration is bigger than the mesh of solid and solid adsorption by mesh sieve out some less than. The drilling fluid returned from the well head flows from the feed tank to the surface of the vibrating screen. The solid phase is discharged from the tail of the screen and contains a liquid phase smaller than the solid phase of the mesh. The sieve flows into the drilling fluid system to complete the separation.
Safety operation of shale shaker for drilling fluid:
It must be determined that the transport locking device is removed prior to use. The equipment can not be repaired, moved or even removed by the use of the vibrating screen. The equipment shall be operated and maintained according to the safety instructions and warning signs given on the equipment.
Maintenance of mud drilling fluid vibrating screen:
According to the vibration motor safety warning, the motor rules, reasonable maintenance, such as filling lubricating oil, etc.;
In the process of use, the screen should be carefully observed, inspection and so on. The damaged screen mesh and the completely damaged screen shall be repaired or replaced in time;
Make necessary cleaning of vibrating screen and screen so that the screen can have a longer life, after each end.
In order to make the use of vibration screen to achieve the best, regularly and systematically monitor the overall situation of the vibration sieve and maintenance.

The client is local drilling client for HDD project. The client is providing water well drilling contract to government companies, government oil drilling companies etc. Last year in Feb, 2015, the client bought two sets mud cleaning system. Each set mud system only with one mud recycling tank, mounting with one set shale shaker & one set mud cleaner.
Recently, the client is requiring one more compact mud system for water well drilling, 500gpm system with two tanks. One shaker tank is with shale shaker and mud cleaner, one mud mixing tank with agitators or centrifugal pumps.
Simple introduction of GN 500gpm mud system as below.
One shale shaker mud tank system including: one set shale shaker, one set mud cleaner, two sets centrifugal pumps. The shale shaker is GN patent 3 panel shale shaker, which have over 5 years jobsite experience. The shaker can work well in different hard conditions. The mud cleaner is GN 3 panel mud cleaner with GN compact design, down deck shaker and desilter cones. Another tank is mud mixing tank with mud agitators, mud guns and mud hopper for chemical mixing.
Except for this mud system, GN drilling waste management equipment is also very popular in the world.
Waste management centrifuge: GN decanter centrifuge is working after replacing USA brand centrifuges. The centrifuge can work for solids control, waste management, waste water treatment ect. In solids control application, 2500rpm is generally used for mud weight cutting, and 1800rpm to 2000rpm is generally used for barite recovery. In drilling waste management, 2500rpm to 3000rpm is generally used for removal the fine solids. In waste water treatment, higher speed centrifuge is required after chemical enhancement.
Vertical cuttings dryer is also called VG dryer, VG dryer can treat the drilling cuttings discharged from shale shaker, the OOC after VG dryer can reduce to about 3% to 5%, and the dry solids can be collected by cuttings skips and transport by trucks to a cuttings center for final treatment.
