【摘要】 大地震发生后,在断裂带开展科学钻探是研究地震发震机理的快速反应和科学计划手段。测井技术是重要的井中地球物理探测方法。本文结合日本Nojima断层科学钻探、美国San Andreas科学深钻、台湾车笼埔钻探和中国汶川地震科学钻探研究成果,综述了国内外地震科学钻探计划实施和研究进展,对比和分析了测井技术在其中发挥的作用和取得的成果。最后,对地震科学钻探井中观测研究提出了建议,并展望了测井技术在地震科学钻探中的应用。更多还原

【Abstract】 New information about large earthquakes can be acquired by drilling into the fault zone quickly following a large seismic event,which is important for the study on the seismic mechanism in the fault zones.Geophysical logging is an important geophysical means in boreholes.Recent progresses in scientific drilling programs were summarized,which included such as Janpan Nojima science drilling,U.S.San Andreas fault science drilling,the Taiwan Chelungpu drilling program,China Wenchuan Earthquake Scientific Drilling,and their applications of geophysical logging.The log analysis results and their roles were discussed and summarized.Finally,some advices about bore geophysical observation were proposed and the future demands of logging technology for earthquake scientific drilling were considered.更多还原
