水平定向钻在庄浪供水工程复杂段的应用优化OA

To address the risks arising from significant elevation differences and complex geological conditions during directional drilling construction of Section 4 of the Zhuanglang Emergency Water Supply Project of the Taohe River Diversion Phase II Project,the on-site equipment layout and the trajectory of guiding hole were optimized based on actual site conditions.At the same time,the drag force was calculated and made compatible with the equipment specifications.The mud system,borehole enlargement,and drag operations,as well as all process risk control techniques were improved.Field implementation has demonstrated that this scheme can effectively prevent problems such as collapse of the borehole walls and excessive drag force,enhance construction quality and efficiency,meet environmental protection standards,and can provide references for non-excavation construction of water conveyance pipelines under similar complex geological conditions.
