For a long time, the water problem has been a major challenge for the local villagers' lives and agricultural development. The local water resources are scarce, and the only few old wells have limited water volume and poor water quality. During the dry season, the villagers even need to transport water from several kilometers away, and agricultural irrigation is extremely difficult.By chance, the local village committee learned that the SL750S drilling rig from Shandong Zhengyuan performed well in well-drilling operations. They decided to invite a professional drilling team to use this model drilling rig to try to solve the water problem.After the drilling team arrived, they first conducted a detailed geological survey of the area. The geological conditions here were complex, with hard rock layers and an unclear groundwater level, which posed great challenges to the drilling work. However, the SL750S drilling rig, with its outstanding performance, gave the team members great confidence.The SL750S drilling rig was equipped with a powerful engine, with strong power, and could easily handle hard rock layers. Its advanced hydraulic system, with precise operation, lifted and lowered the drill pipe smoothly and efficiently. The large torque rotary device of the drilling rig enabled the drill bit to drill quickly, improving work efficiency.The drilling operation officially began, and the drilling machine's roar broke the tranquility of the mountain village. As the drill pipe continued to penetrate deeper underground, every meter forward was filled with unknowns and challenges. During the drilling process, multiple layers of hard rocks were encountered, and the drill bit was severely worn, but the stable performance of the SL750S drilling rig ensured that the operation did not stop. Technicians adjusted the drilling parameters according to the changes in the rocks, and after several days of continuous hard work, the drilling depth gradually approached the expected value.Finally, when the drilling hole reached 500 meters, a clear stream of groundwater gushed out from the hole. "Water is coming! Water is coming!" The villagers on the scene cheered excitedly, with tears welling up in their eyes. This clear spring not only solved the villagers' water supply problem but also provided sufficient water for local agricultural irrigation.The water output of this well was stable, and the water quality, after testing, fully met the drinking and irrigation standards. Now, the villagers no longer have to worry about water supply, and the crops in the fields are thriving under the abundant water supply. The SL750S drilling rig from Shandong Zhengyuan used its strength to write a successful chapter, bringing new vitality and hope to the remote mountain village, and becoming the "hero" in solving the water problem.  

In the Democratic Republic of the Congo (DRC), the uneven distribution and difficult access to water resources have long been a major challenge affecting the local people's livelihoods. In several villages located in [specific area] of the country, people have relied on rainwater storage and long-distance water collection for a long time, with scarce water sources and poor water quality, which have seriously affected their daily lives and health. To fundamentally solve the water problem, a drilling project aimed at finding high-quality water sources was put on the agenda. The Shandong Zhengyuan FSL500 drilling equipment stood out in this mission and took on a crucial role. The Shandong Zhengyuan FSL500 drilling rig can reach a maximum drilling depth of 500 meters, with a drilling diameter ranging from 105 to 400 millimeters, a working wind pressure of 1.6-6 Mpa, a gas consumption of 16-55 m³/min, a fast ascent speed of 23 m/min, and an engine power of 132 kW from Cummins. The winch has a lifting force of 1.5 T. It provides a solid guarantee for drilling operations in complex geological conditions. When it arrived at the construction site in the DRC, the project team encountered severe challenges. The local geological structure is complex, with hard rocks and unstable sand layers mixed in the strata. Traditional drilling equipment is prone to problems such as stuck drill bits and well wall collapse when operating in such strata, greatly hindering the drilling progress and success rate. Additionally, the construction site is remote, with inconvenient transportation and difficulties in equipment and material supply. The harsh climate of high temperatures and heavy rainfall further increased the difficulty of the construction. Facing complex geological conditions, the technicians carried out targeted debugging and optimization of the FSL500 drilling rig. Utilizing its advanced compressed air reverse circulation drilling technology, they effectively solved the problem of poor rock debris discharge and improved drilling efficiency. For the instability of the sand layer, a special casing protection process was adopted, precisely controlling the mud weight and drilling speed to successfully avoid well wall collapse accidents. To overcome the impact of harsh construction environments, the project team carefully planned the equipment transportation route, pre-stored materials, and built stable rainproof and sun protection facilities to ensure the safety of equipment and personnel. In the hot environment, they arranged construction time reasonably and adopted a shift system to ensure the health and efficiency of the construction personnel. After continuous efforts, the FSL500 drilling equipment finally successfully penetrated the complex strata and detected high-quality water sources underground. Clear water gushed out, marking the successful completion of this drilling project. This achievement significantly improved the water supply situation for local residents, ending their long history of water shortage, and injected new vitality into the local economy and social stability. The successful application of the Shandong Zhengyuan FSL500 drilling equipment in the DRC demonstrates its outstanding performance and reliability, and provides valuable practical experience for solving global water shortage problems. In the future, it is believed that this equipment will play an important role in more similar projects and contribute to improving the living environment of humanity.
