摘要
在对扇三角洲沉积体系沉积微相的研究中,发现各沉积微相的展布特征与细分粒级的砂岩相对百分含量具有一定的统计相关性,提出在传统沉积相研究基础之上,利用各粒级砂岩的相对百分含量(粗粒沉积砂岩与砂岩、粉细砂岩与砂岩、泥质砂岩与砂岩等各个相对单因素的厚度百分比值)来定量刻画沉积微相平面展布特征的研究方法,并对单因素等值线图进行分析。将该方法应用于欢双地区沙二段扇三角洲沉积微相的研究中,取得了较好的应用效果,为定量编制碎屑岩沉积体系中各沉积微相平面展布图提供了新的思路,为欢双地区滚动勘探及井位论证提供了可靠的地质依据。
The sedimentary microfacies characterization of the fan deha sedimentary system shows a statistical correlation between the distribution patterns of each sedimentary nficrofacies and the relative percentage of sandstones with subdivided grain sizes. Based on the researches of traditional sedimentary facies, the relative percentage of each sandstone grade （ the relative thickness percentage of coarse-grained sandstone vs sandstone, fine sandstone vs sandstone, argillaceous sandstone vs sandstone, etc. ） is used to quantitatively characterize the lateral distribution patterns of sedimentary microfacies and analyze the univariate contour map. This research is applied to characterize the sedimentary microfacies of fan delta in Sha2 Member of Huanshuang, which shows a favorable application. This research could provide a new idea for the quantitative preparation of the sedimentary microfacies in the clastic sedimentary system and also could provide a reliable geological basis for rolling exploration and well deployment in Huanshuang.
