泌阳凹陷核三段地震沉积学研究
|
摘要
泌阳凹陷深凹区核三段发育辫状河三角洲、滑塌浊积扇及近岸水下扇砂体,受到技术方法和研究手段的限制,沉积相分布范围不明确,尤其是对滑塌浊积扇砂体不能进行详细的刻画。在地震沉积学理论指导下,首先采用提高分辨率、相位调整等技术将叠后三维资料调整到适合地震沉积学研究的最佳状态,然后利用地层切片技术,制作了展现沉积微相分布和沉积演化过程的切片数据体,最后综合分析岩心、录井、测井等资料,对典型地层切片进行沉积砂体的精细解释,预测了沉积相在时空上的展布和演变,为该凹陷寻找滑塌浊积扇等隐蔽油气藏提供了较为可靠的依据。
Braided delta,slump turbidite fans and nearshore subaqueous fan are developed in the sand group III of He-3 Formation in depression area of Biyang Sag.Restricted by the research techniques and methods,the distribution of these facies is unclear yet,especially that of the slump turbidite fans.Under the guidance of the theory of seismic sedimentology,and by using the technique of enhancing the resolution and phase shift,the 3D post-stack seismic data were adjusted to the optimal states.Then by using the technique of strata slicing,the sliced cubes were made to display the distribution of sedimentary microfacies and reflect the evolutionary history.Finally,on the basis of comprehensive analysis of core,lithology and well-logging data,the sandbodies of the typical slices were interpreted subtly,and the distribution of sedimentary facies was predicted.This study provides a reliable approach in exploration of latent traps.
