摘要
建立高分辨率等时地层格架对认识地下单砂体展布规律、研究储层非均质性及分析注采矛盾的岩性油气藏勘探和开发具有重要的地质意义。通过对双城气田扶余油层进行高分辨率层序地层学研究,制定了沉积单元划分原则、对比方法;优选出了分层标准井,建立了封闭主干对比剖面。首次进行了约54000井层次的整体、统一、精细的沉积单元划分与对比,把研究区扶余油层划分为3砂组17小层39个沉积单元,从而建立起了高分辨率等时地层格架。
To establish high resolution isochronal stratigraphic framework which may be to knowledge distribution regularity of the subsurface single sand body,to study reservoir heterogeneity,to analyse injection and produced fluid contradiction has important geologic significance for exploration and development of the lithologic reservoir.The subdivision principle of sedimentary units and correlation methods is established;the standard wells are selected,and set up main correlation sections by means of high resolution sequence stratigraphy study of Fuyu oil bearing layer in Shuangcheng gas field.For the first time,approximately 54 000 times unify is completed and elaborated subdivision and correlation of all sedimentary units,dividing Fuyu oil bearing layer of target area are 3 sand groups 17 sublayers 39 sedimentary units,consequently,establishing high resolution isochronal stratigraphic framework.
