What‘s the principle of fluid passing through the Shale Shaker

The principle of fluid passing through a Shale Shaker

The main purpose of the Shale Shaker is to remove the useless solid phase of the drilling fluid as much as possible without the total amount of waste drilling fluid. To achieve these two projects, the Shale Shake must be required to separate drilling fluid and drilling cuttings as much as possible while removing drilling cuttings and other solids. Generally, the Shale Shake can remove the largest amount of solid phase in a static state. Stopping the vibration of the Shale Shake is the easiest way to remove the largest amount of solid phase, but this method also wastes a lot of drilling fluid. Regardless of the requirement that the Shale Shake must process as much drilling fluid as possible, the method of removing the solid phase by standing still will greatly increase the drilling cost.

The drilling fluid flows down onto the Shale Shaker and flows through the screen cloth. If the Shale Shake is in a static state at this time, a certain hydraulic head must be applied to the drilling fluid to allow it to flow through the screen cloth. The downward force causes the drilling fluid to pass through the screen surface, and the larger solid phase cannot move downward with the downward force, so the liquid and solid phases can be separated on the surface of the screen cloth.

When the screen cloth moves downwards, the large solid phase remains on the shaker screen and moves on the screen surface to the outlet of the Shale Shaker. This is the reason why the elliptical, circular and linear motion screen surfaces can transport the solid phase.

When the Shale Shaker moves in an elliptical, circular or linear manner, the shaker screen surface moves upward so that the fluid passes through the screen surface. The advantage of the linear motion Shale Shaker is that it can separate the solid phase from the liquid phase and then discard it from the drilling fluid. The liquid phase has two advantages: it not only provides an additional hydraulic head force to the fluid, but also When the screen cloth moves upward, a downward inertial force is generated, which significantly increases the drilling fluid processing capacity of the Shale Shaker. At the same time, the vibration of the Shale Shaker can also make the screen surface shear the drilling fluid, thereby reducing the viscosity of the drilling fluid, and more effectively controlling the solid content of the drilling fluid.
