成像测井解释模式探讨

从地层微电阻率扫描成像及井周声波成像测井的原理及研究现状出发，以大量的第一手资料为基础，结合国内外的成像测井研究成果，探讨建立了成像测井解释模式的基本方法，阐述了各种成像测井解释模式的含义，分析成像测井解释模式所代表的地质意义。从成像图的颜色、形态、地球物理意义，地质意义出，以形态分类为主线，地质意义为核心，将像解释模式划为４类：Ⅰ类模式按有无地质意义分类，Ⅱ类模式按形态分类，Ⅲ类模式基本按颜色分

Discussion on Imaging Log Interpretation Mode

On the basis of the principle of formation microresistivity imaging log and circumferential acoustilog and the research of imaging log made both at home and abroad, the basic way to establish imaging log interpretation mode is investigated. With a large number of firsthand materials, the implications of interpretation modes and their geological meaning are expounded. The images have different colors, patterns geophysical meanings and geological meanings. Using the patterns as the main clue and the geological meaning as the hernel, the image interpretation modes are classified into four types: the first type of mode is to classify the images by geological meanings, the second by patterns, the third by colors and the fourth by geological characteristics. So far as the second type of mode is concerned, the image can be classified as blocky shape (bright block and dark block), flaser, linear shape (single linear and associated linear shapes), symmetrical trough, spot (bright spot and dark spot), radom and oblique shapes, wood grain shape, unsymmetrical trough and blank mode. Although this interpretation mode is quite ambiguous, as a way of thinking and a tool it is still a good method for the interpretation of imaging log.
