成像测井图像解释模式及典型解释图版研究

Image Interpretation Modes and the Typical Interpretation Chart for Imaging Well Logging

阐述了成像测井地质解释的一般思路。成像测井的图像特征主要表现在图像颜色变化和几何形态两个方面 ,在总结大量成像测井解释实例的基础上 ,以这两种特征为依据 ,将成像测井图像特征概括为块段状模式、条带状模式、线状模式、斑状模式、杂乱模式、递变模式、对称沟槽模式、空白模式、规则条纹模式、不规则条纹模式等 10类、 17个次级类型的典型图像模式 ,论述了每种模式的颜色、形态、地球物理特征及其代表的地质意义。在图像解释模式的指导下 ,通过岩心资料标定建立了 52种特征地质现象的解释图版 ,并以具有不同图像模式的 5种地质现象为例进行了说明。成像测井图像解释模式的提出和典型地质现象解释图版的建立在后继的成像测井地质解释中具有重要的指导意义和广泛的应用前景。

A general consideration of geological interpretation for imaging well logging is described The imaging well logging has the characteristics of image color variation and geometric shapes On the basis of summing up a lot of cases of the logging interpretation and application of the charateristics denoted above,typical imaging patterns are introduced,which includes 10 kinds of the blocky,flaser,linear,spot,random and oblique,graded,symmetrical trough,blank,regular and irregular stripe modes and 17 grades The color,shape and geophysical charateristics and geologic meaning of each mode are also introduced Under the guidance of imaging interpretation modes,52 interpretation charts of typical geological phenomena are determined by calibrating core data Description is made by taking 5 geological phenomena with different imaging modes as examples The establishment of imaging well logging interpretation modes and the typical geological phenomena interpreting charts have great significance for guidance and wide application prospects
