FSL's Continuous Circulation Drilling System (CCDS) is an innovative technology designed to optimize drilling fluid management, enhance drilling efficiency, and improve safety. The system maintains continuous circulation of drilling fluid during the process of drill string connection and/or disconnection, effectively reducing bottom hole temperatures, improving the applicability of various technologies, and minimizing potential risks.

In traditional drilling operations, during the process of drill pipe connections or disconnections, it is common to stop and start the pumps, leading to fluctuations in bottom hole pressure. This can cause the settling of cuttings, which affects hole cleaning and drilling progress. However, FSL's Continuous Circulation Drilling System avoids this issue by maintaining continuous fluid flow. The system ensures stable equivalent circulating density throughout the drilling process, keeping bottom hole pressure stable and preventing the shocks caused by operational interruptions, which guarantees hole cleaning and quality.

Another key advantage of this system is its ability to continuously discharge cuttings. This function not only improves drilling efficiency but also significantly reduces the occurrence of drilling accidents. By precisely controlling the flow of drilling fluid, the system ensures that cuttings and rock debris are consistently cleared, preventing blockages or other potential problems at the bottom of the well.

Proven to be both innovative and reliable, FSL's Continuous Circulation Drilling System is widely used in complex drilling environments. It enhances the safety and economic efficiency of drilling operations, reduces unplanned downtime, and significantly improves operational stability and efficiency.
