摘　　要：赣州科学钻探NLSD-1孔是大陆科学钻探选址预研究项目6个钻孔之一,该孔地层复杂,自然弯曲严重,采用高粘度、高密度泥浆绳索取心钻进,全孔轨迹实现人工受控,施工难度大。详细介绍了该孔施工技术及创新成果,对施工过程中的经验与教训进行了总结,并提出了对深部钻探施工技术的体会与认识。Scientific drilling hole NLDS- 1 in Ganzhou is one of the 6 boreholes in the pre-research project on the location for CCSD. Because of the complex formations and serious natural bending,the wire-line core drilling was used with high viscosity and high density mud and the drilling trajectory was manually controlled for this borehole. The paper introduces the hole construction technology and innovation achievements,summarizes the experiences in the construction process and expounds the understandings from the technology in deep drilling.
