Abstract:Braided delta,slump turbidite fans and nearshore subaqueous fan are dev elo ped in the sand g ro up III

of H e 3F ormat ion in depr essio n ar ea of Biy ang Sag.R estr icted by the r esear ch techniques and methods,the

dist ributio n o f t hese facies is unclear y et,especially that of the slump tur bidit e fans.U nder the g uidance o f the

theory of seismic sedimento lo gy ,and by using the t echnique o f enhancing the resolution and phase shift,the

3D post stack seismic data w ere adjusted to t he optima l states.T hen by using the technique of strata slicing,the

sliced cubes w ere made to display the distribution of sedimentary microfacies and reflect the evolutionary histor y.Fi

nally,o n the basis of comprehensive analysis o f cor e,lithology and well lo gging data,the sandbodies of the typical

slices w ere interpreted subtly,and the distr ibution of sedimentary facies was predicted.T his study provides a reliable

approach in ex plor ation of latent tr aps.

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。关键词:提高分辨率;相位调整;地层切片;地震沉积学;核三段;泌阳凹陷
