GN Solids Control has successfully delivered and commissioned a high-performance 750HP workover rig solids control system for China Oilfield Service Company . The system, designed to enhance drilling efficiency and environmental safety, features state-of-the-art technologies to optimize solids removal and ensure smooth operations in demanding oilfield environments.
Key Components of the System
1. Mud Tank System
The system includes a robust mud tank engineered to store and circulate drilling fluids efficiently. Its modular design ensures easy integration with other solids control equipment while maintaining a compact footprint.
2. GNZS594K Shale Shakers (2 Units)
At the core of the primary solids control stage are two GNZS594K linear motion shale shakers. Renowned for their high processing capacity and adaptability, these shakers are widely used in oil and gas drilling, large-scale HDD (horizontal directional drilling), and industrial separation applications. The GNZS594K series supports customizable motion trajectories (linear or elliptical) and can be upgraded to a negative pressure shale shaker configuration upon request, further enhancing separation efficiency for complex drilling conditions.
3. GNZS594K-2S12NK Mud Cleaner
The secondary and tertiary solids control stages are powered by the GNZS594K-2S12NK mud cleaner, a compact yet powerful unit integrating desander and desilter hydrocyclones with an integrated vibrating screen. This multi-functional device efficiently removes fine solids (15-44 microns) while minimizing space requirements, making it an ideal choice for mid-to-high-density mud systems.
4. GNLW452D Medium-Speed Decanter Centrifuge
For advanced solids separation, the system incorporates the GNLW452D decanter centrifuge. With a bowl length-to-diameter ratio of 3.4:1 or 4:1, this dual-motor-driven unit (75HP main motor + 30HP back-drive motor) delivers cost-effective removal of fine particles from lightweight drilling fluids. Enhanced safety and operational monitoring are enabled through optional features such as main bearing temperature sensors and vibration sensors.
5. Auxiliary Components
The complete package is supported by critical ancillary equipment including sand pumps, agitators, mud hoppers, and an advanced electrical control system, ensuring seamless coordination across all stages of the solids control process.
