摘　　要：曙光潜山从20世纪70年代末开始勘探,至今已有多年。最初由于资料较少,将潜山地层分为元古界和太古界。为进一步探明潜山内幕,开展地层精细对比评价,利用岩石组合特征、电性特征、古生物特征等对曙光潜山内幕地层纵向上划分为古生界、元古界、太古界的三元结构,结合测井解释倾角资料进行了多井对比,并在最新的地震资料上标定了潜山顶面、古生界底、高于庄组底和太古界顶面,然后在地震解释成果的基础上,编制了曙光潜山前中生界顶面地层岩性分布图,在平面和立体上对潜山内幕地层的分布情况进行了深入的解剖,对曙光潜山内幕地层有了深入的认识。From the late 1970 s,Shuguang buried hill has been explored for many years.Originally,due to less data,the hill formation was divided into Proterozoic and Archean.To further ascertain the buried hill,stratigraphic fine correlation and evaluation were carried out by using rock assemblages,electrical and paleontological characteristics to classify the hill formation as a ternary structure of Paleozoic,Proterozoic and Archean longitudinally.Combined with the inclination data from well logging interpretation,multiwell correlation was conducted.And the hilltop,Paleozoic bottom,Gaoyuzhuang formation bottom and Archean top were calibrated in the latest seismic data,then on the basis of seismic interpretation results,the lithology distribution chart for the top surface of Mesozoic strata in Shuguang buried hill was compiled.On the plane and three-dimensional,the authors analyzed the distribution of buried hill formation and obtained further understanding for Shuguang buried hill formation.
