摘　　要：本文针对中国主导的IODP349、367、368/368X航次的钻探取心存在的问题,通过详细分析取心数据,分别对沉积岩和硬岩地层所采用的取心器具、影响岩心采取率、岩心质量、取心效率等因素进行具体分析,分类总结了大洋钻探取心受岩性、工艺器具和外部环境等多方面综合影响的原因和程度,初步提出了相应的改进措施。In view of the coring problem for the China-led IODP349、367、368/368X voyage, through analyzing the coring data, the coring tools and factors affecting the core recovery, core quality and cored efficiency in sedimentary rock and hard rock are researched, the causes and degree of the influence factors such as lithology, technical tools and external environment etc. which affect the ocean drilling coring are classified and summarized. The corresponding improvement measures are put forward.
