Types and advantages of drilling shale shaker

A drilling shale shaker is a vital piece of equipment in the drilling process. It is used to separate solids and fluids that come out of the wellbore during drilling operations. The drilling shale shaker is a vibrating screen that utilizes a mesh to filter out the cuttings from drilling fluids. In this article, we will discuss the different types of drilling shale shakers and their advantages.

1, Types of Drilling Shale Shakers

Linear motion shale shaker:

Linear motion shale shakers are the most common type of shale shaker. They use a linear vibratory motion to separate the cuttings from the drilling fluids. The linear motion shale shaker consists of a screen bed that is inclined at an angle to allow the fluid to flow over the screen surface. The vibration causes the solids to move down the screen and the fluids to pass through the screen and flow into the mud tank.

Balanced elliptical motion shale shaker:

The balanced elliptical motion shale shaker is designed to provide a better separation of solids and fluids. The elliptical motion is achieved by using two vibratory motors that are synchronized to produce an elliptical motion. The elliptical motion provides a more efficient separation of solids and liquids compared to the linear motion shale shaker.

Dual motion shale shaker:

The dual motion shale shaker combines both linear and elliptical motion to provide better separation of solids and fluids. The dual motion shale shaker uses two vibratory motors that operate independently to produce linear and elliptical motion. The dual motion shale shaker provides better separation efficiency, reduces screen blinding, and extends screen life.

2, Advantages of Drilling Shale Shakers

Reduced fluid loss: The shale shaker is designed to remove solids from the drilling fluid, which reduces the amount of fluid that is lost during the drilling process. This results in significant cost savings for the drilling operation.

Improved drilling efficiency: The shale shaker removes the cuttings from the drilling fluid, which allows the fluid to be reused in the drilling process. This improves drilling efficiency and reduces the time required to complete the well.

Reduced equipment wear: The shale shaker removes the cuttings from the drilling fluid, which reduces the wear and tear on other drilling equipment such as the mud pump and mud motor.

Environmental protection: The shale shaker reduces the amount of drilling waste that is generated during the drilling process. This reduces the environmental impact of drilling operations.

Improved safety: The shale shaker improves safety on the drilling rig by reducing the risk of accidents caused by the accumulation of cuttings on the rig floor.

In conclusion, drilling shale shakers are an essential piece of equipment in the drilling process. They help to separate the cuttings from the drilling fluid, which improves drilling efficiency, reduces fluid loss, and protects the environment. The different types of shale shakers offer varying degrees of separation efficiency, and choosing the right shale shaker for the drilling operation is crucial to achieving optimal results.

How to clarify the classification of the drilling fluid systems

Drilling fluid systems can generally be divided into 3 categories and 7 sub-categories. They are liquid-based drilling fluid, gas-based drilling fluid and mixed-based drilling fluid.

Water-based drilling fluid systems, including oil-in-water drilling fluids. Its solid phase particles are suspended in water or brine, and the oil can be emulsified into the water. At this time, the water is the continuous phase.

The composition is: bentonite + water + chemical treatment agent + weighting material + drill cuttings.

Oil-based drilling fluid system, including full-oil drilling fluid, water-in-oil drilling fluid, and synthetic-based drilling fluid, whose solid phase particles are suspended in oil, and water or brine is emulsified in oil, that is, oil is the continuous phase.

The composition is: diesel oil+asphalt/organic soil+treatment agent.

Synthetic-based drilling fluid system: It is mainly a synthetic system. Including ether-based, ester-based, poly-olefin-based and isomerized-olefin-based drilling fluids, etc.

Shale shaker working efficiency determines the mud process efficiency

In the oil drilling process, The drilling fluids from the well can be transported to the mud control equipment by mud pump. As the first phase equipment of mud control, The drilling fluids shale shaker is one of the mud-water separation equipment and has the characteristics of the earliest separation, the fastest separation, economical and efficient. Shale shaker working efficiency determines the mud process efficiency of entire mud control system. so we must know what factors determine working efficiency of the drilling fluids shale shaker. There are three deterministic factors of shale shaker working efficiency.

The First Factor: Shale Shaker Mode of Vibration

There are three types vibration modes shale shaker. It is inear motion, circular motion, elliptic motion. If the center of gravity is at the vibrator, it can form the circular motion. If the center of gravity is above the vibrator, It can form circular motion. For the elliptic motion, the screen must have a slope in order to transportation of drill cuttings, but it can reduce the capacity of its screen. If the center of gravity is above and in front of the vibrator, The shaker can formed inear motion. The inear motion shale shaker has the constant speed of transportation of drill cuttings.

The Second Factor: The Amplitude and Frequency of Shale Shaker and vibrating motor

The capacity of shale shaker depends on three parameters: amplitude, mode of vibration, rotation speed of vibrating motor. The rotation speed of vibrating motor determines the vibration frequency of shale shaker. The higher of vibration frequency of shale shaker, the better of the solid phase screening. Generally, vibration frequency of the domestic high frequency shale shaker is approximately 2000 times /min.

The vibration mass and eccentricity determines amplitude of shale shaker. Amplitude is the vertical distance of the movement of shale shaker. Vibration strength is centrifugal acceleration of the vibrator. It reflects the mesh size of the force acting on the solid particles. In theory, The larger the vibration amplitude of shale shaker, the better of the removing effect. But after the vibration strength increases, The force of shale shaker is also increased. if so the expectancy shaker life can become shortened. Therefore we should considered comprehensively when designing and using.

The Third factor: Mesh and Material of Shale Shaker

Generally speaking, there are 2-4 shaker screens in shale shake. Drilling fluids must pass the first screen into a second screen, and so on. If the screen size is not suitable or be torn, the efficiency of solid-phase separation can decrease dramatically. If the screen can not be install reasonably, the screen will soon be worn or torn quickly. So when you select the screen, you must pay attention on the material of shaker sreen.

Mud shaker is a widely used mud treatment equipment

Mud shaker is a widely used mud treatment equipment. In the field of oil drilling, it is often used as a first-level solids control equipment to process drilling mud, also known as solids control shaker. According to the needs of solid control equipment, mud shale shaker can be divided into various types, including: single-layer mud shale shaker, multi-layer mud shale shaker, drying mud shale shaker, variable frequency shale shaker, etc. Solid control shale shaker used in oil drilling field, and mine shale shaker in mining field, etc.

The working principle of shale shaker
The exciting force generated by the vibration motor drives the sieve bed to do linear, circular, elliptical or translational elliptical motion. The screen will play the role of filtering and screening, screening out solids such as large particles of drill cuttings, and the treated clean mud with fine particles will fall into the vibrating screen bin for the next level of treatment. The separated large solid particles (usually above 74 microns) are transported to the outside of the sieve bed under the excitation force and discharged to the outside of the tank.

Scope of application of mud shaker
Primary or secondary or tertiary solids control treatment for mud and liquid to be treated in onshore and offshore oil and gas drilling/coalbed methane excavation/trenchless directional crossing/piling engineering/waste sewage, mud treatment and other projects. In short, it is the primary treatment of mud and solid-liquid mixtures suitable for various environments.

The difference in structure and technical factors of shale shaker

The drilling mud shale shaker is a mechanical process that separates particles of a certain size through a screening device. The shale shaker is the first in a multi-stage system and the most widely used mud cleaning tool. All modern drilling complexes are equipped with shale shakers, and the number of shale shakers on a drilling rig sometimes reaches six. The shale shaker removes the solution from coarse cutting particles larger than 70-80 microns. The content of particles of this size in the solution is relatively small, but the effect of the shale shaker depends not only on the amount of rock removed, but also on the reliability and centrifugation of the solution prepared for the deeper cleaning of the subsequent hydrocyclone sludge separator machine.

The shale shaker is an integral part of the drilling mud cleaning system, designed to clean the drilling mud from the drilled rock particles while drilling. Shale shaker-the first stage of cleaning, removes solution from 10-20% of sludge over 75-100 microns in size. Shale shaker occupies most of the mud removal and is the most common mud removal tool.

The shale shaker is different in structure and the following technical factors:

-Vibrating motion form of the vibrating frame (circular, elliptical, linear, linear-elliptical);

-The vibration amplitude of the vibrating frame;

-The acceleration of the vibration motion of the vibrating frame;

-Screen surface area;

-According to the number of layers: For better cleaning, the screen can be single or multiple layers.

The working principle of the shale shaker in the petroleum industry

In the modern oil and mining industry, the production process requires the mandatory use of a special type of equipment-shale shaker, whether it is a single version or a composite form designed for multi-stage processing of specific raw materials. In the oil and gas industry, shale shaker are used to clean drilling washing fluid (solution) from drilling rock particles (drilling mud).

Shale shaker are usually used in the initial stage of drilling mud cleaning. By processing the solution on a shale shaker, the large rock particles with a size of 70-80 microns or more are sieved out. The shale shaker is designed in structure, and the device is quite simple.

The main nodes of the shale shaker include support frame; power frame; screen panel; protective cover and so on. The operating principle of the shale shaker is also quite simple: the drilling mud contaminated by the drilling rock particles is fed into the surface of the screen plate fixed in the fixed frame at a certain inclination angle. Under the action of the oscillating movement, the cleaned material moves along a certain track along the surface of the mesh. During such vibration treatment, the gravitational separation of the small and large fractions of the sludge occurs on the surface of the screen: pollutant particles larger than the mesh size do not pass through it, and because of the continuous movement under the influence of shale shaker, the large the inclusion cleaning drilling mud, and the smaller sludge particles contained therein, are naturally filtered through the sieve holes, and then they are transferred to the smaller sludge cleaning solution through a special port.
