The FSL500 crawler water well drilling rig of Shandong Zhengyuan Drilling and Production Intelligent Equipment Co., Ltd.

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.
