摘要
饶阳凹陷是冀中坳陷油气最富集的典型陆相断陷凹陷,具备形成岩性地层油藏的良好地质条件。研究认为,该凹陷岩性地层油藏的形成与分布主要受4种因素控制,其中凹陷构造背景和古地貌控制着沉积体系与砂体的展布,碳酸盐岩台地基底与新生代强烈的掀斜断块活动、沉积-储集相带和富油洼槽则对岩性地层油藏的分布与富集起着决定性作用。针对凹陷陡带、洼槽带、中央潜山构造带和斜坡带的成藏特点,建立了相应的岩性地层油藏成藏模式。
Raoyang sag is a typical continental rifted sag richest in hydrocarbons in Jizbong depression and has good geological conditions for forming lithologic-stratigraphic reservoirs. Researches indicate that the forming and distribution of lithologic-stratigraphic reservoirs in this sag are controlled by four control factors, among which the structural setting and paleogeomorphology control extension of sedimentary system and sand body; the basement of carbonate platform and strong tilted block movement in Cenozoic and the sedimentary-reservoir facies belt and trough rich-in oil control definitively the distribution and abundance of lithologic-stratigraphic reservoirs. The reservoirforming patterns of lithologic-stratigraphic reservoirs are established on the basis of reservoir-forming characters of steep belt, trough belt, central buried-hill structural belt and slope belt within the sag.
