我们从一九七六年开始在皖南碳酸盐岩发育地区开展找油工作,穿越了一些剖面,采集样品分析鉴定,并在石炭——二叠系中选择典型剖面用碳酸盐岩研究新方法进行了尝试,证实了皖南地区具有碳酸盐岩厚度大、分布面积广,可能生储油层系多,油气苗丰富等有利条件,因而有广阔的勘探前景。这一地区由于沉积巨厚(沉积盖层可达万米以上)及褶皱、断裂及岩浆活动强烈,应具有相当的活动性,其褶皱的主体方向为北东向。往往呈复背斜、复向斜形式出现。基底由上元古界蓟县系和青白口系浅变质的片岩、千枚岩及古火山岩组成。褶皱程
We started to look for oil in the carbonate developing areas of southern Anhui since 1976. We traversed some of the sections and collected samples for analysis and identification. We selected carbonate rocks from the Carboniferous-Permian series to study new This paper attempts to prove that the southern Anhui Province has favorable prospecting conditions due to its favorable conditions such as thick carbonate rocks, wide distribution area, abundant oil and gas reservoirs and abundant oil and gas. Due to the thick sediments (up to ten thousand meters of sedimentary caprock) and folds, fractures and magmatic activity, this area should be quite active with the main direction of folds being NE direction. Often complex anticlines, complex syncline appears. The basement consists of supergene metamorphic schist, phyllite and ancient volcanic rocks in the Upper Proterozoic Jixian and Qingbaikou lines.
