实用地震沉积学在沉积相分析中的应用
|
摘要
提出了实用地震沉积学理念,探讨了实用地震沉积学的技术体系。实用地震沉积学的技术体系包括精细等时地层格架、最小等时研究单元、岩相物理分析和定量地震相分析等,其中定量地震相分析包括年代地层切片技术、地震属性和波形分析技术等。以鄂尔多斯盆地塔巴庙D气田上古生界岩性油气藏为例,重点阐述了定量地震相分析技术在沉积相分析中的应用。实例分析表明,实用地震沉积学在沉积相分析和岩性圈闭预测方面具有独特的优势。
The key methods and techniques system of applied seismic sedimentology was described,including detailed equitime strati- graphic frameworks,minimum isochronal strata unit,lithofacies physical study,and quantitative seismic face analysis,etc.The quantitative seismic facies analysis technique involves chrono-strata slicing technique,seismic attributes and seismic waveform analy- sis.Taking the Neopaleozonic lithologic deposit in gas field D of Tabamiao area in Erdos basin as an example,the application of quantitative seismic facies analysis technique in sedimentary facies study was elaborated.The actual analysis shows that the applied seismic sedimentology has unique advantages in sedimentary facies analysis and in lithologic trap forecasting.
