Study on Pipeline Pulling and Landing Technology Using Horizontal Directional Drilling Rig

摘要: 随着海洋油气资源开发的加速，传统海管拖拉登陆技术因效率低、成本高及环境扰动大等问题面临严峻挑战。本研究以惠州大亚湾石化区海管项目为依托，提出“定向钻机替代线性绞车”的创新方案，通过三维动力学建模(OrcaFlex软件)与实际工程验证，系统分析其技术可行性、经济性与环保性。结果表明：定向钻机技术通过“扩孔–拖拉”一体化工艺，将施工效率提升40%，钻杆最大米塞斯应力(548.99 MPa)与海管应变(0.031%)均满足规范要求；材料成本降低30%，海床扰动面积减少85%。研究证实，该技术可显著突破传统方法的局限性，为海洋工程绿色施工提供了高效解决方案，并为深水与多管并行铺设奠定技术基础。

Abstract: With the acceleration of offshore oil and gas development, traditional pipeline landing techniques face challenges of low efficiency, high costs, and environmental disruption. This study proposes an innovative solution—replacing linear winches with horizontal directional drilling (HDD)—validated through the Huizhou Daya Bay Petrochemical Project. Using 3D dynamic modeling (OrcaFlex) and field tests, we systematically analyzed technical feasibility, economic viability, and environmental performance. Results demonstrate that HDD’s integrated reaming-pulling process improves efficiency by 40%, while drill pipe stress (548.99 MPa) and pipeline strain (0.031%) comply with DNVGL-ST-F101 standards. Material costs decreased by 30%, and seabed disturbance was reduced by 85%. This technology overcomes limitations of conventional methods, provides an eco-efficient solution for marine engineering, and establishes a foundation for deepwater and multi-pipeline applications.
