A 3000HP drilling rig requires high standards for drilling mud solids control equipment due to its larger scale and more demanding operational needs. GN Solids Control designs the mud system to accommodate larger volumes of drilling fluids and ensure efficient solids control throughout the drilling process.
The mud system includes an 80bbl trip tank, complete with a centrifugal trip pump. The trip tank features a level meter with a 0.5bbl level indicator, ensuring precise monitoring of the mud volume. There are three active mud tanks in the system: a shale shaker tank, an intermediate tank, and a suction tank, each with a 500bbl capacity. These tanks are essential for maintaining the right balance of drilling fluids during operations.
In addition, the system includes four reserve tanks for mud storage, with a total capacity of 2000bbl. The setup also includes three water tanks and a 70bbl pill tank to support various operations and drilling fluid maintenance.
A comprehensive mixing system is integrated into the mud system for deep drilling rigs. The mixing system consists of two mixing hoppers, three centrifugal mixing pumps, and one shearing pump for use and backup. This setup ensures that drilling fluid is mixed effectively to maintain consistent viscosity and performance.
To handle the high flow rates and large volumes of drilling fluid, the system uses three sets of GNZS596K double-deck shale shakers. These shakers are specifically designed for large-capacity applications and utilize the same size replacement screens for both the upper and bottom decks, ensuring ease of maintenance and consistent performance.
After the shale shakers, the system includes a 1500GPM mud gas separator, a vacuum degasser, and a mud cleaner to further treat the mud and remove gases, solids, and contaminants. 100hp centrifugal pumps are used to feed the desander and desilter units, ensuring proper flow rates and efficient separation of fine solids.
The system is also equipped with necessary mud agitators and mud guns to keep the mud in suspension and maintain optimal fluid properties during the drilling process.
This comprehensive mud system ensures that the 3000HP drilling rig operates efficiently, with advanced equipment for solids control, fluid management, and waste disposal.
