摘要

通过对霸县凹陷南洼槽构造、沉积特征和成藏条件研究,首次建立了该区古近系层序地层等时格架,将沙一下亚段—沙四段划分为7套三级层序,明确了沉积体系及沉积相在等时地层格架内的空间展布及特征,指出文安斜坡内带、"凹中隆"背斜构造带和洼槽带为3个岩性地层圈闭发育的有利区带。综合应用地震相分析、地震属性分析及地震反演等技术进行岩性地层圈闭的有效识别。构建了斜坡带、背斜带和洼槽区岩性地层油藏模式,对有利勘探目标进行精细落实优选,钻探文安1、文安11井均获成功,研究表明该区是岩性地层油藏规模勘探的有利区,对冀中坳陷富油气凹陷岩性地层油藏勘探具有一定指导作用。
Based on study on structure, sedimentary characteristics and reservoir forming conditions of Baxian southern subsag, the sequence stratigraphic synchrone frame of the region is first set up, where the formation from lower submember of Es1 to Es4 is divided into seven third-order sequences and the space distribution as well as the feature of depositional systems and sedimentary facies are confirmed, and three favorable zones of developing lithologic stratigraphic trap are given. The lithostratigraphic traps are effectively identified by comprehensively using such approaches as analysis of seismic facies and seismic properties, inversion. Lithostratigraphic reservoir models in slope area, the central anticline belt and deep depression area are established, and then the favorable exploration targets are exactly selected and confirmed. Wenan 11 and Wenan 1 wells were successfully drilled, which proves that the area is favorable for lithostratigraphic reservoir exploration and is of guiding significance for further exploration in other petroleum-rich subsags of Jizhong Depression.
