摘要
本研究的主要目的是利用地震反射数据和属性分析，在尼罗河三角洲盆地东部的West El Qantara近海地区识别上新世沉积通道和天然气行为对地震特征的影响。综合利用地震属性(相干性、振幅相对偏移量“AVO”建模和振幅提取)，增加了油气地震特征、相和小型地质构造的信息。三维地震解释结果与已知的尼罗河三角洲盆地陆上区域构造-地层模式相匹配，显示出满意的匹配，为油气特征提供了更多细节。
IMAGING THE PLIOCENE CHANNEL SYSTEM USING 3D SEISMIC ATTRIBUTES AT THE WEST EL QANTARA REGION, NILE DELTA BASIN, NORTHERN EGYPT
The main objective of the present study is to identify the Pliocene depositional channel and the gas behavior on seismic characteristics at the on-shore West El Qantara Region, in the eastern part of the Nile Delta Basin, using seismic reflection data and attributes analysis. The integrated use of seismic attributes (coherency, Amplitude Versus Offset “AVO” modeling and amplitude extraction) added information about the hydrocarbon seismic signature, facies and the minor geological structures. The 3D seismic interpretation results were correlated with the known regional structural–stratigraphic fashion of the onshore Nile Delta Basin and showed a satisfied matching, added more details about hydrocarbon signature.
