地震属性技术在郭局子洼陷沙二段岩性油藏描述中的应用

The application of seismic attribute technology in lithology reservoir description of Es2 Member of Guo Juzi sag

郭局子洼陷沙二段储层以滩坝砂体和小型扇体为主,分布规律性不强,勘探程度较低。我们采用弧长属性和相干分析技术较为准确地识别并描述了储层分布范围和低序级断层,有效地指导了该区该类储层的勘探。

Es2 Member of Guo Juzi sag is mainly foreland anc small-scale fans, which is in irregular distribution. This type of reservoir is currently on a low degree exploration stage in the area. In the paper, arc length attribute and coherence technology are used to predict and describe the sand distribution and small faults. The research has effectivel, provided the guidance to the exploration of this kind o reservoir in the region.
