摘　　要：以南方海相碳酸盐岩油气远景区的物性统计规律为基础,用综合物探方法联合正演,提取出典型构造、断层及油气藏的重磁电理论异常特征;结合重力、大地电磁(MT)油气藏模型正、反演计算,将理论异常特征作为提取研究目标特征的对比依据,进行(油气)地质—地球物理综合解释。总结出了南方海相碳酸盐岩油气远景区典型断层油气藏和地层油气藏模型的理论综合物探异常特征,并应用于中上扬子克拉通ZL地区综合物探剖面资料的联合解释,划分了有利储集构造带,推测了有利储层的空间展布特征,为研究区进一步的油气勘探部署提供了依据。Based on the statistical laws of marine carbonate ’s physical properties in the potential area from Southern China,we joint integrated geophysical methods with forward modeling technology to extract the theoretical anomalous characteristics of typical structures,faults and reservoirs.Combined forwarding with inversion computation of gravity and magnetotelluric numerical simulating for the oil-gas model,taking the theoretical anomaly characteristics as contrasting basis of extracting research objective characteristics,we carry out integrated petroleum geology and geophysical interpretations.Moreover,we summarize the integrated geophysical theoretical anomaly characteristics of typical fault reservoir model and stratigraphic reservoir model,which are applied on integrated interpretation in ZL area of middle-upper Yangtze craton.By this means,we divide the favorable structural zone,suggest the spatial distribution characteristics of favorable reservoirs,and provide the basis for further oil-gas deployment in research area.
