【摘要】 地震沉积学是在油气勘探开发的需要下产生的,具有鲜明的技术特色和良好的应用前景。文章阐述了地震沉积学的概念和学科特点,认为地震沉积学可以按研究尺度分为地震地貌学和储层地震学,从应用角度提出了地震沉积学的研究思路,并首次提出最小等时研究单元的概念,即三相(地震相,测井相,岩芯相)结合研究时井震统一的尺度,是沉积分析时一个最小的地质成图单元。选择鄂尔多斯盆地塔巴庙D气田上古生界岩性油气藏为例,阐述了地震沉积学分析技术在沉积相分析方面的应用方法,展示了地震沉积学研究技术在建立精细等时地层格架、岩相物理分析、多属性地震相分析等方面良好的学科优势。更多还原

【Abstract】 The seismic sedimentology came into being under the oil-gas exploration development,has the bright technical characteristic and the better application prospect.Based on the concept and the discipline characteristic of seismic sedimentology,the study divided earthquake sedimentology into the seismic geomorphology and the reservoir seismography,proposed research method from the application aspects.The paper for the first time proposed the concept of the smallest isochronal strata unit:a three phase(seismic,oil well logging,core)combined with the uniform unit of well and seismic is the smallest geological chart unit during conducting depositional analysis.Taken the early Palezoic D gas field in the ERDOS Basin as an example,this paper applied seismic sedimentology in facies sedimentary analysis.The case study proves that seismic seidimentology is of favorable advantages in the analysis of sedimentary facies,lithofacies physical natures and multiattribute seismic phases.更多还原
