Hunan Yuanyu Exploration Technology Development Co., Ltd.
Our esteemed company, Hunan Yuanyu Exploration Technology Development Co., Ltd., boasts a rich heritage with roots tracing back to its previous incarnation as Hunan Zhuangyuan Geological Equipment Co., Ltd., an esteemed extension of the Hunan Provincial Institute of Geophysics and Geochemistry. Originating from the mechanical repair workshop of the illustrious 409 team, our journey began in earnest with the establishment of the 409 Repair Factory in 1989. The year 1992 marked the birth of our Diamond Products Research Institute, setting the stage for future innovations. By 2003, we evolved into the Zhuangyuan (Group) Company, encompassing the dynamic duo of Hunan Zhuangyuan Diamond Products Co., Ltd. and Hunan Zhuangyuan Geological Equipment Co., Ltd. Our strategic partnership with Hunan Hongyu Water Resources and Hydropower (Group) Co., Ltd. in 2016 gave rise to the formation of Hunan Yuanyu Exploration Technology Development Co., Ltd., positioning us as a national high-tech leader in the design, production, R&D, and operational services of cutting-edge geological equipment, including drilling rigs, drilling tools, diamond drill bits, and advanced centralized slurry injection systems. Notably, our innovative 'centralized slurry grouting system' has earned a coveted spot on Hunan Province's inaugural list of recommended emergency equipment procurement.
In recent years, our company has garnered a host of prestigious accolades: the 'Zhuangyuan' brand has repeatedly earned the distinction of 'Famous Trademark of Hunan Province,' while we have been celebrated as a 'Hunan Province Contract Abiding and Creditworthy Unit' and a 'Hunan Province Integrity Construction Demonstration Unit' on numerous occasions. In a testament to our commitment to excellence, we proudly received the esteemed title of 'National High-Tech Enterprise' in 2021.
Prioritizing technological innovation lies at the heart of our mission, as evidenced by our impressive portfolio of over 10 patents. We enjoy a long-standing, synergistic relationship with respected academic institutions such as China University of Geosciences (Wuhan) and Central South University, proudly serving as the industry-university-research base for China University of Geosciences (Wuhan). Our collaborative efforts with the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences have resulted in the critically acclaimed marine shallow sampling drilling rig, earning rave reviews from highly satisfied users.
