【摘要】 断陷湖盆是中国东部陆相沉积盆地中最具典型意义的油气勘探对象 ,但其相变剧烈 ,层序对比难度大 ,物源补给体系复杂。因此 ,在这类地区的油气勘探过程中 ,必须依靠地质与地球物理技术的综合应用 ,即在明确的构造沉积背景条件下 ,以层序地层分析为基础 ,确定目标区的沉积层序格架 ,继而结合应用地震技术 ,通过沉积微相分析、属性分析、正反演、全三维可视化等工作 ,确定具体的勘探目标 ,才能收到事半功倍的效果。更多还原

【Abstract】 Fault lake basin is the object of oil-gas exploration having typical meaning in continental sedimentation basin of east China,which is characterized by rapid changes of facies,difficulty in correlation of sequences and complex supply of source rock.Therefore,During the procedure of oil-gas exploration in that regions,it is necessary to integrative use of geologic and geophysical techniques,that is in a background conditions of evident structural deposition,it is mainly on the basis of sequence-sedimentary analysis and determination of depositional sequence framework in the target zone,then,defining the concrete prospecting objects by combining with application of seismic techniques and through the analysis of sedimentary micro-facies and attributes,forward and inversion works and full 3D visualization,which can result in getting twice the result with half the effort.更多还原
