【摘要】 运用各种物探手段对渤海海域A构造所在三维区及其东南部的二维区地震资料进行连片地震资料解释、成图,并结合以往勘探成果对目的层新近系明下段及馆上段的储盖组合、油气运移等石油地质特征进行分析、研究,为该构造区实施进一步勘探提供了可靠依据。研究运用了方差、三维可视化、波阻抗反演、分频以及基于波形的地震相分析等先进的地球物理技术。更多还原

【Abstract】 This report mainly focuses on research of Structure A in Bohai Sea. 3D seismic data and 2D seismic data in the South-eastern part are incorporated to interpret as a whole with a variety of seismic techniques. Based on the former exploration results, we also analyze the petroleum features including combination of reservoir and cap, oil and gas migration etc. Of the target stratum including the lower member of Minghuazhen formation and the upper member of Guantao formation in Upper Tertiary unit. New insights are obtained for further exploration in this structural area. Meanwhile, advanced geophysics techniques were used in this research including variance, 3D visualization, elastic impedance inversion, spectrum decomposition and seismic facies analysis based on wave shape.更多还原
