摘要: 针对南岭科学钻探-1孔(NLSD-1)100~1 000 m井段,利用测井磁化率和井中三分量磁测资料及岩性编录资料研究了其地层不同岩性的磁化特征,同时对井中三分量磁异常进行了分析和解释。不同岩性的磁化率从高到低依次为变质细屑沉凝灰岩、变质粉屑沉凝灰岩、多种矿化变质细屑沉凝灰岩、硅化变质细屑沉凝灰岩、硅化变质粉屑沉凝灰岩、多种矿化变质粉屑沉凝灰岩、凝灰质板岩、多种矿化凝灰质板岩;井中三分量磁异常主要是由钻孔旁侧磁性体和变质沉凝灰岩引起的。

Abstract: Taking NLSD-1 borehole (100~1 000 m) of Nanling Scientific Drilling as the object,magnetization characteristics of different lithologies are researched by utilizing magnetic susceptibility of well logging,borehole magnetic tri-component data and record data of lithology.Meantime,anomalies of borehole magnetic tri-component are analyzed and interpreted.Magnetic susceptibilities of different lithologies diversified from high to low are: metamorphic fine-cutting sedimentary tuff,metamorphic dusty-cutting sedimentary tuff,multi-mineralized metamorphic fine-cutting sedimentary tuff,silicified metamorphic fine-cutting sedimentary tuff,silicified metamorphic dusty-cutting sedimentary tuff,multi-mineralized metamorphic dusty-cutting sedimentary tuff,tuffaceous slate and multi-mineralized tuffaceous slate; Anomalies of borehole magnetic tri-component are principally caused by magnetic body beside borehole and metamorphic sedimentary tuff.
