地震沉积学在下石盒子组河流相层序界面识别中的应用
|
摘要
河流相地层在短期和超短期旋回的地震等时对比中存在严重的穿时现象,致使河流相砂体横向展布研究困难。本文以地震沉积学Wheeler域地层对比技术基础,提出以区域等时地层格架为约束的局部区域或同一沉积体系内开展与短期旋回对应的砂体等时对比新思路,在分频剖面上实现了对短期旋回界面的等时对比追踪,结合Wheeler域短期旋回的变时窗属性提取技术,准确刻画了短期旋回的沉积微相展布图,提高了河流相储层研究的精度。文章以鄂尔多斯盆地D气田下石盒子组河流相储层预测为例,阐述了地震沉积学相关理论和技术方法的应用过程。
The severe discronous phenomenon exist in the seismic isochronous correlation for the fluvial facies strata in the short term and super short term cyclone,resulting in difficulty for the research on the lateral distribution of the fluvial facies sandbodies.It is proposed in the seismic sedimentology that the slicing technique in the Wheeler domain plays a major role in the research,with the new thought of the isochronous correlation between local area/same sedimentary system constrained by regional isochronous strata grid and the short term cyclone the isochronous correlation and tracking for the short term cyclone interface was realized on the frequency division sections,by combining the short term cyclone time window-varying extraction technique in the Wheeler domain,the sediment micro-facies distribution map of the short-term cyclone was accurately delineated,the accuracy of the fluvial facies reservoir research was raised.By taking the fluvial reservoir prediction for the Lower Shihezi Formation in D gas field in Ordos Basin as the example,the application process of the related theory and technical methods in Seismic Sedimentology was elaborately described in this paper.
