  The uneven distribution of water resources has long plagued the lives of local residents and the development of agriculture and industry in Kazakhstan. The arrival of Shandong Zhengyuan drilling rigs has brought new hope to this land, like a ray of light.  In southern Kazakhstan, the Shandong Zhengyuan SL600S drilling rig astonished Kazakhstani engineers with its high-efficiency performance. Equipped with an intelligent variable-frequency impact system, it can automatically adjust impact frequency and torque based on underground rock conditions, completing tasks in just a few hours that traditionally took two days. When water gushed from the wellbore, nearby construction workers and residents alike erupted in astonishment.  With its reliable performance and outstanding construction results, the Zhengyuan drilling rig has established a strong reputation for Chinese high-end drilling equipment in Kazakhstan, laying a solid foundation for further cooperation.

Project Background The Jinan Olympic Sports Center, as a landmark sports venue in Jinan City, covers an area of 81 hectares and includes a stadium, a gymnasium and other facilities such as "one stadium and three buildings". It is the core venue for large-scale events and public activities. The surrounding supporting projects, due to functional requirements, need to complete tasks such as well drilling and foundation drilling. They must not only ensure long-term water supply for the project but also adapt to the construction restrictions in the densely built environment around the venue. This poses extremely high requirements for the efficiency, stability and adaptability of the equipment and the site. Performance advantages The Zhengyuan SL400S drilling rig, with its numerous core advantages, has become the key equipment for this project: Equipped with a 92-kilowatt six-cylinder direct injection engine, it offers powerful and stable power output; The hydraulic system uses high-quality components, enabling precise adjustment of parameters such as speed and torque, suitable for various processes including deep hole drilling and pipe-following drilling; The maximum drilling depth reaches 400 meters, meeting the requirements of deep-hole operations; The crawler design, combined with a wide chassis, has a large ground contact area, allowing for flexible movement in complex sites and reducing ground damage caused by rolling. Process and Challenges During the construction process, two core challenges were encountered: Firstly, the surrounding area was densely populated with buildings, which imposed strict requirements on the size and operational precision of the construction equipment, and it was necessary to avoid any impact on the venue facilities; Secondly, the geological strata were complex, with alternating hard rocks and soft soil layers, which often led to low drilling efficiency or cave-ins.To address these issues, the SL400S drilling rig demonstrated significant advantages: Through its tracked movement and compact design, it could precisely position and operate in narrow areas; When encountering hard rocks, it could efficiently break the rocks by using a large torque output in combination with the sub-bit hammer process; When dealing with soft soil layers, it could promptly adjust the advance parameters and adopt pipe-following drilling to effectively prevent the collapse of the hole wall. At the same time, the fully hydraulic control reduced the manual operation intensity, improved the continuity of the operation, and ensured smooth connection of each process. Project outcomes Ultimately, the SL400S drilling rig successfully completed all the drilling tasks. The water wells it drilled had stable water output and met the water quality standards, fully meeting the water demand of the project. During the construction process, there were no equipment malfunctions, and the overall construction period was shortened by 12% compared to the planned schedule, significantly reducing the construction cost. Its stable performance in complex environments and its friendly nature towards the surrounding areas were recognized by both the construction party and the venue management party, making it a model of efficient drilling equipment in large-scale venue supporting projects .

Shandong Zhengyuan SL1200K crawler water well drilling rig successfully entered the 1600-meter hot spring well project in Tianshui, Gansu In Tianshui, Gansu, an exploration of geothermal resource development is in full swing. Shandong Zhengyuan crawler water well drilling rig SL1200K successfully entered the 1600-meter hot spring well project here, becoming a key force in the local geothermal development process. 1. Project background Tianshui area is rich in hot spring resources. Hot spring water is rich in a variety of minerals that are beneficial to the human body, such as strontium and lithium, and has a high value for bathing and recuperation. The development of hot spring resources is of great significance to promoting the development of local tourism and enhancing tourism brands. . This time, Tianshui decided to further dig underground resources, develop deeper hot springs, and create a hot spring tourism project with larger scale and characteristics. 2. Performance advantages of SL1200K drilling rig Shandong Zhengyuan SL1200K crawler water well drilling rig is an efficient top-drive, fully hydraulic, multi-functional drilling rig. It is technologically advanced and can adapt to various complex formation conditions, showing excellent performance in this project. The drilling rig has extremely high operating efficiency and adopts advanced power systems and drilling technology, which greatly shortens the construction period; at the same time, it is reliable and durable. After strict quality inspection and practical verification, it can maintain stable operation during long-term and high-intensity construction, reducing maintenance costs and downtime. III. Construction process and challenges 1. Complex formation: Tianshui has a complex geological structure, with different rock hardness in the formation, and there are special geological structures such as faults. During the drilling process, the drilling rig needs to frequently deal with rocks of different hardness, which puts extremely high demands on the stability of the drill bit and the drilling rig. With its powerful torque and precise control capabilities, the Zhengyuan SL1200K drilling rig effectively copes with these challenges and ensures smooth drilling.2. Depth challenge: The goal of this time is to drill a 1,600-meter deep well. As the depth increases, the underground pressure and temperature increase, and the difficulty of drilling increases exponentially. The SL1200K drilling rig is equipped with an advanced pressure and temperature monitoring system to grasp the underground situation in real time, adjust the drilling parameters in time, and ensure the safety and quality of construction.3. Equipment coordination: The entire construction process involves the coordinated operation of multiple equipment, including mud pumps, air compressors, etc. The good compatibility and operability of the SL1200K drilling rig enable it to work closely with other equipment to form an efficient construction team. IV. Project Results After the unremitting efforts of the construction team, Shandong Zhengyuan's SL1200K crawler water well drilling rig successfully completed the drilling of a 1,600-meter hot spring well. The water temperature and water output of the new hot spring well met the expected standards, providing strong support for the further development of Tianshui's hot spring tourism industry. The success of this project not only proves the excellent performance of the SK1200 drilling rig, but also lays a solid foundation for Shandong Zhengyuan's market expansion in the western region. The outstanding performance of Shandong Zhengyuan's crawler water well drilling rig SL1200K in the 1,600-meter hot spring well project in Tianshui, Gansu, demonstrated its leading technology and strong strength in the field of deep well drilling, and is expected to provide high-quality solutions for the development of geothermal resources in more regions.                                                                                   

The SL600S crawler water well drilling rig of Shandong Zhengyuan Drilling and Production Intelligent Equipment Co., Ltd. performed outstandingly in a key water conservancy project, successfully helping to drill multiple high-quality drinking water wells in a certain area, effectively solving the daily water use problems of local residents. This construction case has also become a model in the industry.
