摘要

徐家围子断陷深层勘探取得了重要成果,但是营四段砾岩研究难度较大,导致该后备潜力储层研究程度较低。文中应用地震沉积学的先进理论技术方法(沉积模式和规律指导下的基于井震结合的相位转换、三维可视化、地层切片、分频、相干等技术方法)针对营四段砾岩展开研究,确定了该区为北北西主物源,刻画出了扇体轮廓及内部结构,为后期勘探开发奠定了重要基础。同时,在实践应用的过程中更加明确了地震沉积学中技术方法的适用条件及注意事项。
Important results had been achieved in deep-formation exploration in Xujiaweizi Depression,but the difficult business of conglomerate of Member 4 of Yingcheng Formation in Xujiaweizi Depression,resulting in the low level of researching of the potential reservoir.Using seismic sedimentology theory and advanced methods(phase convert,3d visualization,strata slicing,frequency decomposing,coherence and other technical methods which based on well-seismic tie) to studying conglomerate of Member 4 of Yingcheng Formation.Ultimately determined the main provenance from NNW,depicted the outline and internal structure of fan delta,which laid an important foundation for exploration and development for later.In practice,applicable conditions and notes are more clearly in the process of application of technical methods of Seismic sedimentology.
