The SL600S crawler-type water well drilling machine of Shandong Zhengyuan Intelligent Equipment Co., Ltd. successfully e

2025-08-14

In the karst region of Qiandongnan, a challenge related to the development and utilization of geothermal energy has quietly begun. The local area plans to build a ground source heat pump system to provide clean and efficient heating and cooling energy for the surrounding areas. However, the geological conditions here are extremely complex, with intense karstification, and the fourth-order alluvial deposits are porous and loose, making the well walls prone to collapse. Conventional drilling equipment and techniques are difficult to handle such conditions.
At this critical moment, the Shandong Zhengyuan SL600S drilling rig stepped in heroically. It was equipped with an American Shulife 750XH 1050 series medium-low pressure mobile screw air compressor, forming a powerful drilling "CP".
The construction team meticulously planned and adopted a three-pass drilling structure. During the first pass, they controlled the SL600S drilling rig and forcefully drilled with an Ø241.3mm drill bit, successfully penetrating the complex fourth-order loose rock layer. Then, they quickly lowered the Ø219.1mm casing, like providing a sturdy protective umbrella for the fragile well wall, effectively preventing well wall collapse. After the second pass, the drilling rig continued to advance deeper, reaching the bottom of the cave with great difficulty. Then, it precisely lowered the corresponding casing again, laying a solid foundation for the subsequent operations. In the third pass, the SL600S drilling rig replaced the Ø152mm drill bit and drilled to a designed depth of 151m. 
With the completion of the last meter of drilling, the exciting moment finally arrived. Clear groundwater gushed out as expected. This marked the successful completion of the mission by the SL600S drilling rig. Not only did it ensure the smooth construction of the test well, but it also provided key data support for the subsequent large-scale ground source heat pump system construction, helping the region make significant progress towards green energy development.latest company news about The SL600S crawler-type water well drilling machine of Shandong Zhengyuan Intelligent Equipment Co., Ltd. successfully e 0latest company news about The SL600S crawler-type water well drilling machine of Shandong Zhengyuan Intelligent Equipment Co., Ltd. successfully e 1latest company news about The SL600S crawler-type water well drilling machine of Shandong Zhengyuan Intelligent Equipment Co., Ltd. successfully e 2
