摘要

通过对黄骅坳陷歧口凹陷勘探现状的分析，明确了该凹陷斜坡区地层岩性油气藏是下一步攻关的主要对象。根据斜坡的位置、形成特点和展布特征，将歧口凹陷斜坡进一步划分为盆缘断控陡坡、坡折型缓坡、断阶型缓坡和凹陷中断裂斜坡。在歧口凹陷成藏模式分析的基础上，根据对所划分的4类斜坡的特点展开控砂模式、疏导体系及烃源岩演化程度等的分析，分别总结了4类斜坡区地层岩性油气藏的分布模式，并结合勘探实践进行了验证，指出了歧口凹陷斜坡区地层岩性油气藏的勘探前景。

Abstract

Based on the present exploration situation, we consider that the lithologic reservoir should be the next exploration target in the slope area of Qikou sag. According to slope location, formation feature and exhibition feature, the slope area of Qikou sag is divided into basin fringe fault abrupt slope, break gentle slope, fault terrace gentle slope and fault slope. Based on accumulation model of petroleum accumulation in the Qikou depression, we discuss the pattern of sand distribution, dredge system and thermal evolution of source rock, and then concluded the distributed model of lithologic reservoir in the slope area. This model is testified by exploration practice, suggesting that the exploration of lithologic reservoir in the slope area of Qikou sag would be better.

Key words： Qikou sag; Lithologic petroleum reservoir; Slope area; Source rock.
