摘要
大地电磁测深(MT)为地球物理勘探方法之一,本文通过对YF地区MT资料的解释研究,系统总结了电性结构在垂向上的组合类型分为"三低两高"Ⅰ型、"两低一高"Ⅱ型及"三低一高"Ⅲ型;划分出三种类型在平面上的分布特征及对印支面之下地层的解释;预测中、上古生界的残存状况,为油气勘探选区选带等地质综合评价提供依据。
MT is a geophysical survey method.Based on interpretation of MT data on the YF area,this paper systematically summarized three vertical combination types for a conductive structure,i.e.,"three lows and two highs"Ⅰ,"two lows and one high"Ⅱ and"three lows and one high"Ⅲ,introduced their planar distribution features and their interpretation of stratigraphy beneath the Indosinian plane,providing a basis for prognosis of middle and upper Paleozoic residual conditions and for geological comprehensive assessment such as choosing oil and gas exploration areas or zones.
