地震弹性反演技术及其在泌阳凹陷油气勘探中的应用
|
摘要
在对叠前弹性阻抗反演发展及原理分析前提下,对比了弹性反演的几种常用方法,阐述了选择的归一化方法的特点。通过在泌阳凹陷试验应用,总结出在处理和解释中值得注意的几个方面,并用弹性参数与油气和岩性敏感性分析,建立纵横波速比同赵凹-安棚地区核三段砂岩分布及其含油气性的模式关系,预测结果符合程度较高。
The progress and principle of seismic elastic inversion were discussed and the comparison between the common methods was made. The normalization method was selected and used in Zhaowa-Anpeng Area of Biyang Depression as having advantages over others. By discussion on several key measures in inversion process and interpretation, the better relations between Vp/Vs ratio and H3 formation reservoir parameters are built according to the oil or lithologic character sensitive analysis with elastic seismic attributes. The estimated results are proven with better consistency.
