飞雁滩——老河口地区馆上段河道砂体描述技术

Description technique of channel sand body of upper Guantao formation in Feiyantan-laohekou area

本文以飞雁滩-老河口河道砂体油藏为研究对象,重点探讨了馆陶组河道砂体的速度变化规律、地震反射特征,同时利用正演技术分析了砂岩振幅与厚度、含油性及沉积相的关系,并总结了分频、R ave等属性分析新技术的特点及对河道砂体油藏的描述效果。对类似地区具有较好的借鉴意义。

Aiming the reservoir of channel sand body in Feiyantan-laohekou area to be our research object, the paper probes into the rule of velocity change of channel sand body in Guantao formation and probes into the character of seismic reflection. Using the technique of forward modeling, we analyze the relation between amplitude of sandstone and the thickness of sandstone and the oil-bearing probability and the sedimentary facies. We summarize the character of the new attributes analysis technique like spectral separability and Rave. At last we summarize the effect of description to the reservoir of thannet sand body. These techniques can also be well used in other areas like Feiyantan-laohekou area.
