FMS地层微电阻率扫描成像测井技术诞生于1986年,1989年首次在大洋钻探中获得应用。它采用纽扣电极阵列沿井壁纵向扫描方式采集地层的电阻率信息,经过适当的数字和图像处理后转化为井壁地层的二维微电阻率图像。FMS资料具有分辨率高(理论分辨率为5 mm)、连续原位测量及定向性等特点,是科学大洋钻探中岩芯地质分析方法的重要补充,具有其他地球物理方法难以替代的作用。从岩芯归位和定向、岩性岩相识别及地层剖面重建、沉积构造和古流方向分析、地层旋回性与古气候周期分析、浊积层厚度统计分析、构造和应力场分析及洋壳研究等7个方面对FMS在科学大洋钻探中的应用现状进行综述,对目前FMS成像测井资料应用中存在的问题及发展方向进行分析,包括利用率不高、定量分析成果欠缺、研究深度和广度有待拓展等。
FMS stratigraphic micro-resistivity scanning imaging logging technology was born in 1986, 1989 for the first time in ocean drilling applications. It collects the resistivity information of the formation along the vertical direction of the borehole wall by using the button electrode array. After proper digital and image processing, it converts the two-dimensional micro-resistivity image into the borehole formation. FMS data has the characteristics of high resolution (theoretical resolution of 5 mm), continuous in-situ measurement and orientation, which is an important complement to the core geological analysis method in scientific ocean drilling. It has the effect that other geophysical methods can not be replaced. From the core homing and orientation, lithology and facies identification and stratigraphic section reconstruction, sedimentary structure and paleocurrent direction analysis, stratigraphic cyclone and palaeoclimate period analysis, turbidite layer thickness statistical analysis, structure and stress field analysis and oceanic crust And other seven aspects of the FMS in the scientific ocean drilling application status quo, the current application of FMS imaging logging data problems and the development of the direction of analysis, including the utilization rate is not high, the lack of quantitative analysis, research depth and breadth To be expanded.
