地层倾角的构造解释交互系统

Interactive System for Structural Interpretation of Dipmeter Data

冯敬英，李好强，王鹏，等．地层倾角的构造解释交互系统．测井技术，１９９８，２２（２）：１１１～１１５地层倾角测井数据构造解释的统计曲线分析技术（简称ＳＣＡＴ技术）具有５种统计图形显示，比传统方法的一种图形（矢量图）得到的信息要全面得多，是提取地层“真倾角”的好方法，可避免许多人为误差。其中分量图更能反映构造特征，给构造解释带来极大的方便。根据ＳＣＡＴ图示能确定井眼穿过地质构造的形态及滑距断层的存在和特征。用ＳＣＡＴ方法在ＳＵＮ工作站的ＸＷｉｎｄｏｗｓ环境下，通过人机交互解释，最终提供地质横剖面图和等高线图。

The Statistical Curvature Analysis Technique (SCAT) for structural interpretation of dipmeter data can provide five statistical graphic displays and get much more formation information than the traditional method which provides only vector plot. SCAT is a good way to acquire “true dips”, avoiding many artificial errors. The component plot provided by SCAT can better reflect the structural feature and is very convenient for structural interpretation. Morphology of geological structure drilled through by borehole and the existance and features of slip faults can be determined according to SCAT products. Geological cross sectional profile and contour charts can be easily obtained with SCAT and interactive interpretation, which run under X Windows environment on SUN workstation.
