How to choose the right shale shaker screen?

Shale shaker screens are an essential component of the drilling equipment used in the oil and gas industry. They are used to separate solids from drilling fluids and prevent clogging of downstream equipment. Selecting the right shale shaker screen is critical to achieving efficient solids control and maximizing drilling performance. In this article, we will discuss the factors that need to be considered when selecting a shale shaker screen.

1, Screen Type

The type of screen is an important factor to consider when selecting a shale shaker screen. There are three main types of screens: woven wire, perforated plate, and synthetic screens.

-Woven wire screens are made of stainless steel wire mesh and are the most common type of screen used in the oil and gas industry. They offer good durability and are suitable for most drilling applications.

-Perforated plate screens are made of steel plates with holes drilled through them. They are more durable than woven wire screens but are less effective at separating finer solids.

-Synthetic screens are made of polymer materials and are designed to offer higher separation efficiency and a longer lifespan than traditional metal screens. They are particularly suitable for drilling in harsh environments and can be used in place of metal screens for improved performance.

2, Screen Mesh Size

The mesh size of the screen is another critical factor to consider when selecting a shale shaker screen. The mesh size refers to the number of openings on the screen surface per linear inch. The larger the mesh size, the smaller the openings, and the finer the solids that can be separated.

For drilling fluids with larger particle sizes, a lower mesh size is recommended. For fluids with finer particles, a higher mesh size is required to achieve efficient separation.

3, Screen Configuration

Shale shaker screens come in various configurations, including flat, pyramid, and hook-strip screens. Flat screens are the most common and are suitable for most drilling applications. Pyramid screens are designed to increase the amount of surface area in contact with the fluid, which improves separation efficiency. Hook-strip screens are easy to install and remove, making them ideal for drilling operations that require frequent screen changes.

4, Screen Quality

The quality of the screen is an essential factor to consider when selecting a shale shaker screen. Poor-quality screens can result in reduced separation efficiency, increased downtime, and increased operating costs.

High-quality screens are made from high-grade materials and are manufactured to tight tolerances to ensure consistent performance. They should be able to withstand the high pressures and temperatures encountered in drilling operations and resist wear and tear.

5, Screen Quantity

The number of screens required depends on the drilling conditions and the type of shale shaker being used. Most shale shakers require between two and four screens. Using more screens can increase the capacity of the shaker and improve separation efficiency.

6, Price

Price is also a consideration when selecting a shale shaker screen. While it is essential to choose a high-quality screen, it is also vital to select a screen that fits within the budget. Synthetic screens are generally more expensive than traditional metal screens but can offer better performance and longer lifespan.

In conclusion, selecting the right shale shaker screen is critical to achieving efficient solids control and maximizing drilling performance. The factors to consider when selecting a shale shaker screen including screen type, mesh size, configuration, quality, quantity, and price. By considering these factors, drilling operators can select a screen that is best suited to their specific drilling conditions and requirements.

Shale Shaker Working Efficiency Deterministic Factors

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.
