摘要 以"满凹含油"理论为指导,对黄骅坳陷南部孔二段沉积演化背景、沉积相带及烃源岩分布特征开展研究,落实湖盆内部孔二段沉积期发育的坳陷型盆缘辫状河三角洲沉积体系为岩性油气藏分布有利区带,具备形成自生、自储型岩性油气藏的基本条件。同时,对孔二段自生、自储型油气藏分布规律进行分析、总结,结合原始沉积构型与构造的配置关系,提出了黄骅坳陷南部孔二段岩性油气藏潜力区。 With the guidance of 'sag-wide oil-bearing' theory, this paper studies sedimentary evolution, sedimentary facies and source rock distribution for Kong 2 formation in the south of Huanghua Depression, ascertains that the braided river delta sedimentary system of depression-type at basin edge developed in Kong 2 depositional stage within the lake basin is a potential area of lithologic reservoirs, which possess the basic conditions of forming self-generation self-reservoiring type of lithologic reservoirs. The distribution of these self-generation and self-reservoiring type of reservoirs has been analyzed and summarized, and the potential area of lithologic reservoirs in Kong 2 formation in the south of Huanghua Depression is proposed with consideration of the relationship between the original sedimentary configuration and the structure.
