This article presents a novel method for restoring the circulation of drilling fluid during well drilling using a back-suction technique. Unlike traditional methods, this innovative approach eliminates the need for a vacuum pump, significantly reducing both capital and operational costs associated with drilling operations. The study analyzes the proposed technology’s effectiveness, highlighting its ability to accelerate the operations of extending drill pipes, thereby decreasing the time required for these processes by nearly 2.5 times compared to conventional techniques. This improvement is particularly critical in complex hydrogeological conditions, such as those found on the Mangistau Peninsula, where freshwater resources are limited. The flexibility of the proposed method allows for effective adaptation to various working scenarios, including a temporary switch to direct circulation, enhancing the equipment’s operational performance. The research demonstrates that the improved technology is a promising solution for increasing the productivity of drilling operations, which has significant implications for freshwater availability in resource-constrained regions. Future studies are encouraged to focus on optimizing this method and tailoring it to different geological conditions to further enhance drilling efficiency and reliability. Overall, this work contributes valuable insights into advancing drilling technology for water supply wells, aiming to improve sustainability and efficiency in the sector.
