GN Desander and Desilter and Shaker to Indonesia Project

The application of drilling fluid desander, desilter, and shaker in the Indonesian market has gained significant attention due to their high efficiency and cost-effectiveness. This article will explore the principles of their application and analyze their market performance in Indonesia.

1 Principles of Application
The principles of application of drilling fluid desander, desilter, and shaker are essential to understand in order to maximize the efficiency and effectiveness of these equipment in the drilling process. Each of these components plays a crucial role in the solids control system, and their proper application is key to ensure the quality of the drilling fluid and the successful completion of the drilling operation. In this section, we will delve into the fundamental principles of applying drilling fluid desander, desilter, and vibrating screen, highlighting their respective functions and the synergistic effects of their combined application.

The drilling fluid desander is designed to remove solid particles with sizes ranging from 45 to 74 microns. Its principle of application lies in the use of centrifugal force to separate the solid particles from the drilling fluid. As the drilling fluid enters the desander, it is directed into a cylindrical chamber where the centrifugal force causes the solid particles to move towards the outer wall of the chamber. The solid particles are then directed downwards and discharged through the underflow outlet, while the clean drilling fluid is collected from the overflow outlet at the top of the desander. This process effectively removes the larger solid particles from the drilling fluid, preventing the abrasion of the drilling equipment and maintaining the desired properties of the drilling fluid.

On the other hand, the drilling fluid desilter focuses on removing smaller solid particles with sizes ranging from 15 to 44 microns. Similar to the desander, the desilter utilizes centrifugal force to achieve solid-liquid separation. The drilling fluid enters the desilter and is directed into the hydrocyclone, where the rotational motion creates centrifugal force, pushing the solid particles to the outer wall of the hydrocyclone. The separated solid particles are then discharged through the underflow outlet, while the clean drilling fluid is collected from the overflow outlet. By removing the finer solid particles, the desilter complements the desander’s function and further improves the quality of the drilling fluid.

In addition to the desander and desilter, the vibrating shake , also known as the shale shaker, plays a critical role in the solids control system. Its principle of application involves the use of vibratory motion to separate solid particles from the drilling fluid. The drilling fluid is directed onto the vibrating screen, where the vibratory motion causes the solid particles to be separated from the fluid. The separated solid particles are then discharged, while the clean drilling fluid passes through the screen and is collected for further processing. The vibrating screen effectively removes larger solid particles and agglomerates that may have bypassed the desander and desilter, ensuring the drilling fluid’s cleanliness and stability.

Furthermore, the combined application of the desander, desilter, and vibrating screen results in synergistic effects that significantly enhance the solids control efficiency. By sequentially passing the drilling fluid through the desander, desilter, and vibrating screen, the system can effectively remove solid particles of various sizes, ensuring that the drilling fluid meets the required specifications. This integrated approach maximizes the removal of solid particles, minimizes the loss of drilling fluid, and ultimately improves the overall performance of the drilling operation.

In conclusion, the principles of application of drilling fluid desander, desilter, and vibrating screen are based on the fundamental concepts of centrifugal force and vibratory motion for solid-liquid separation. Understanding the functions and applications of these components is crucial for achieving an efficient and effective solids control system. Their combined application ensures the removal of solid particles of different sizes, leading to clean and stable drilling fluid, thus contributing to the success of the drilling operation.
