摘　　要：通过对南盘江北部地区三年大地电磁测深(MT)资料的处理、分析与研究,提出根据电性分布,结合层序地层资料进行沉积相带划分的方法和原理,并划分出了三个主要地质时期的沉积相带分布。经钻孔验证,该方法是有效的,圈定了13处隐伏的油气远景目标,为该地区油气勘探提供了靶区。Through the processing,analyzing and studying of the MT data collected in three years from the northern part of Nanpanjiang area,a method for lithofacies division and its principles were summarized based on the electric distribution in combination with the research results of sequence stratigraphy.In addition,three main lithofacies zones were delineated,which have been verified by subsequent drilling results.

关 键 词：大地电磁测深 油气勘探 南盘江 层序地层 岩相划分 油气远景评价
