测井资料在层序地层识别中的应用探讨

测井曲线蕴含着丰富的地质信息,且具有很高的纵向分辨率,测井曲线的形态、幅度可以反映出岩性和沉积旋回韵律等地层特征,在油气田勘探开发中起着十分重要的作用,因此如何更好地利用测井资料进行层序划分,其层序地层学响应特征如何,其优点与局限性如何等是必须回答的问题。通过调研综述国内外研究成果,得出可以利用测井资料划分层序地层单元,并介绍了常用测井曲线识别层序的方法。

Discussion about the Application of Logging Data in Sequence Stratigraphy Recognition

The logging curve contains abundant geological information, And it has high vertical resolution. The shape, amplitude of Logging curve can reflect the characteristics of lithology and depositional cycles of rhythm formation. It Plays a very important role in the exploration and development of oil and gas fields. Therefore, how to make better use of logging data sequence stratigraphy, its sequence stratigraphy response characteristics, its advantages and limitations of such a system must be answered. Review of domestic and foreign research results of the research, I think they can use log data to divide the sequence stratigraphic units, and recommend a commonly used method of the recognition sequence of well logs.
