What Is Mud Shale Shaker
A mud shale shaker is intensive vibrating equipment. At the initial mud separation stage, they use a motor to develop vibrations. Here mud shale shaker acts as a sieve, and its vibration pushes the drilled mud through a wire cloth screen. If required, the drilled mud is filtered through the mud mud shale shaker and moved into the mud tank for additional processing. A large piece of solids then passes over the screen surface and is discharged for collection and disposal.
Advantages of Mud Shale Shaker
Replaceable
The best part of the mud shale shaker is that it can be easily replaced. It can fit almost all types of shakers available for effective use of the prevailing equipment. Since you do not have to replace the original shaker machine, it saves you a lot of money and turns out to be cost-effective.
Drier cuttings
Mud shale shakers have the capability to minimize the loss of fluid by quickly drying the screen. This happens by spreading the thinner layers of fluid over an enhanced area of the screen, which enables the shakers to possibly screen 1 to 2 api-sized particles, which ideally maximizes efficiency and time.
Has strong corrosion resistance
The bottom frame of the screen box is made of stainless steel, which has strong corrosion resistance and long service life.
Angle adjustment
The angle of the mechanical screen box can be adjusted synchronously on one side, which can meet the needs of the screen box angle adjustment without stopping the machine, and the operation is stable.
Types of the Mud Shale Shaker
End feed
Two types of end-feed and center-feed mud shale shakers are used in the drilling industry which the end-feed shaker is the most common one. The screen of an end feed shaker is rectangular while center feed screens are circular. Because drilling fluid flow pattern is the difference for both screens, so the vibration pattern for end-feed and center feed mud shale shakers is not identical. The screen motion dominates particle velocity on the screen and drilling flow rate though cake and screen. In an end feed mud shale shaker, the motion of the imaginary line created by the intersection of vertical plane parallel with the walls and screen cloth is elliptical. All points on the line perpendicular to the vertical plane parallel with the walls and passing through the screens have identical motion. In a direction perpendicular to the vertical plane parallel with the walls, motion is zero. This type of vibration results in the motion of particles across the screen in a straight path to the mud pits.
Center feed
In the radial distance from the center of the circular feed shaker, the motion of all points on the screen is elliptical. All points vibrate in a vertical plane perpendicular to the radial plane. In this kind of shaker, particles also move in a circular shape in a horizontal plane perpendicular to the radial plane and the screen experiences a 3-D motion. In the elliptical motion screens, motion is identical in all angular location around the center. It proposed that the linear vibration than the circular motion model results in higher efficiency in solids conveyance. He also showed that even elliptical vibration shows higher efficiency compared to the linear motion as a result of that screen life is increased.
Multi-deck shaker
For the multi-deck mud shale shakers, it is recommended that the coarsest mesh size is placed at the top, then the finer mesh size is used as the middle screen and finally, the finest mesh should be placed as the bottom screen. This configuration allows the shaker to collect the finer particles with the highest efficiency. The problem of multi-deck shakers is in maintaining the bottom screen.
One of the most common physical separation techniques in drilling industry is the mechanical screening. Separating tools are classified into moving and static screen equipment in which the machine can be inclined or horizontal. The process of screening is controlled by physical variables such as particle shapes, acceleration, vibration type and bed density. The vibration motion and screen mesh size have their pros and cons in the process of screening. The most effective pattern of vibration is sinusoidal vibration which is applied on the angled screen relative to the horizontal.
The actual flow rate of a mud shale shaker infiltration of drilling mud is less than the capacity of a shaker which processes only fluid. Because of the presence of the solids in drilling mud, the capacity of a mud shale shaker may be reduced due to one of the following effects. The solids larger than the screen openings tend to cover the pores which result in decreasing the screen area for passing drilling fluid and finer solids. For overcoming this problem, frequency should be increased to increase the solid' s velocity. Another way is that the downward angle should be increased but it causes more mud to run off the screen. When screen openings are slightly smaller than particles, the blinding effect reduces the performance of a shaker. The particles which are slightly smaller than openings pass through the pores barely due to weak orientation and low velocity.
Parameters Affecting the Performance of a Mud Shale Shaker
Capacity of shaker
The maximizing capacity of a mud shale shaker is a trade-off between the content of separated cuttings off the screen and filtrated drlling mud. Passed through the screen. For example, if the shaker deck is inclined downward to enhance particles transfer more driling mud flows off the. Shaker channel, and cuttings at the outlet have more moisture while tilting the screen up decreases solids velocity but more fluid is saved. There is an optimum angle for each shaker, depend on the manufacturer, which tilting the screen up. More than that causes solids accumulation on the screen and blocking the screen pores. The physical mechanisms justifying the effect of vibration on the fluid displacement in porous media are not yet known. It is suggested that an increase in flow rate is caused by changes in the pore structure and particle rearrangement. A research was conducted on the effect of vibration on the flow rate of hexadecane as a non-wetting phase in a column flled with water and sand, the hexadecane flow rate increased by increasing amplitude. Another explanation for the effect of vibration on the flow rate is based on the capillary trapping. The capillary trapping mechanism is the most promising one. The idea for this mechanism is based on the interfacial tension which is considered as the most significant parameter on multi-phase flow in porous media.
Particles and drilling fluid
Changing in pore sizes of porous media trap the fluid which leads to variations in capillary pressures. This pressure imbalance changes the flow rate of liquid through the porous media. By applying vibration, we see that vibration of the screen will result in an inertial body force acting on the fluid which this movement pushes the trapped fluid to reflow. Vibration creates an internal circulation in the mud and it gives more time to the fluid to touch the screen and this might be one of the effects of vibration on the enhancement of the flow rate. Particle size distribution and concentration both have an effect on the process of solids-liquid separation. Increasing the solids concentration in drilling mud reduces the performance of the dilling operations. Experimental work shows that muds containing more than 10% by mass solids caused the failure infiltration process. Microbit drilling results indicated that very fine particles in a drilling mud have more adverse effects on the flow rate than larger sizes.
Mud shale shaker working
Materialsize range μbentonite0.001 -0.10barite 1- 10rilled cuttings 1- 1000table.1 shows the size range of different types of particles in dilling fluid which can be separated in a mud shale shaker. A work by cagle showed that an increase in dilling fluid viscosity decreases the flow rate exponentially. It has been suggested that to maximize passing a viscous dilling fluid through screen openings, high frequency and low amplitude should be aplied.
Drilling mud viscosity and shaker
Research on the effect of plastic viscosity and yield values shows that plastic viscosity of drilling mud flowing through the screen and cake has a significant effect on the capacity of a mud shale shaker while yield value has a slight effect on the performance. It has been also shown that increasing the plastic viscosity and yield value of a dilling fluid increases the required screen area used in a shaker. The capacity of a mud shale shaker can be increased by decreasing plastic viscosity and increasing screen area, shaker angle, and acceleration. The install location of the vibrating motors on the mud shale shakers can be considered as one of the parameters involving in the design of shale. Some manufacturers say that if a vibrator is precisely mounted on the shaker support there is no need to incline the shaker downward to get desired mass rate of solids on the screen but one should aware that inclining the screen downward decreases the drilling mud flow rate and increases the moisture content of the particles leaving out the channel of the shaker.
Fundamental Parts of a Mud Shale Shaker
Vibratory motors
Usually, a mud shale shaker works with two motors that apply the vibratory motion on the shaker screen. There are two eccentric weights in the motors to generate a vibrating force when they rotate. The vibrators rotate in opposite directions and create a force on the screen. The force pushes the particles along with the screen and off the screen outlet. The motors can be installed on the vibrating deck or on the support frame.
Screen angling system
The shaker screen plane should be capable of tilting to handle fluctuations in mud flow rates and maximize the use of the screen area. Depend on the type of the shale and drilling process, different angling systems are used which mechanical, hydraulic, and pneumatic mechanisms are the most common. It is reported that mechanical and hydraulic systems are faster than pneumatic mechanism and need less energy to function.
Base
This part works as a platform for the shaker and collector for the drilling mud passed through the shaker screen. Depend on flow rate of mud, different depths can be used.
Screen
This part is the most important part of the mud shale shaker which most of the efforts in improving the performance of a vibrating mud shale shaker concentrate on this part. The screen removes drilled cuttings and sends them to the base and make the filtration process more convenient.
Feeder
This part collects the drilling mud before it flows into the shaker channel. Different types of feeders are used in the drilling industry which the most common one is called weir feeder. This feeder is capable of distributing the drilling mud along the entire shaker screen surface. The feeder has a bypass streamline that sends the mud directly to the collecting tank without being processed by the screen.
Feed tank
A tank is used when the shaker is being repaired or screens are being changed. In the situations that drilling mud is too thick to pass through the screen, the screen is blinded or plugged which in this situation tank is used. A feed tank has a bypass port which allows the drilling mud goes to the mud circulation system.
