【摘要】 在合肥盆地开展了高精度重力、航磁、电法、地震(简称重磁电震)、化探等多种方法勘探的基础上,本文通过对重磁电资料的目标处理,建立起全区地球物理场;应用重磁电震资料联合反演,获得的主要成果有:①完成了印支面及结晶基底构造图;②发现了“影子盆地”;③本区自南而北划分为四个构造带,即前陆冲断带、前渊沉降带、前隆断褶带、隆后斜坡带;④指明前陆冲断带和前隆断褶带是合肥盆地油气勘探突破的有利地区。更多还原

【Abstract】 On the basis of multiple exploration methods such as high precise gravity survey, aeromagnetic survey,electrical survey and seismic prospecting ( simplified as gravity, magnetic, electric and seismic)developed in Hefei basin,the paper built up the feature of geophysical field in the whole area through object-oriented processing of gravity. mag-netic and electric data; applying joint-inversion of above-mentioned geophysical data resulted in fol-lowing results: (1) finished the structural maps of Indosinian interface and crystal basement; (2) dis-covered "shadow basin ";(3)divided the region into four structural belts from south to north; foreland thrust belt, foredeep depressed belt, fore-bulge fault-folding belt and back-bulge slope belt; (4) pointed out the foreland thrust belt and fore-bulge fault-folding belt are prospective areas that can make oil-gas exploration breakthrough in Hefei basin.更多还原
