义和庄凸起北坡油藏分布规律

义和庄凸起邻近车西、大王北、郭局子、四扣等良好的生油洼陷 ,区带成藏条件十分有利。受多期区域构造运动影响 ,义和庄凸起北坡地质结构特征十分复杂 ,含油层系多 ,储层、圈闭类型复杂多样 ,油藏分布广泛 ,是一个典型的复式油气聚集带 ,具有巨大的勘探潜力。本文系统分析了义和庄凸起北坡的成藏条件、油藏类型及分布规律 ,指出潜山、地层超覆、地层不整合等隐蔽性油藏将是下步的主要勘探方向

THE DISTRIBUTION RULE OF RESERVOIRS IN THE NORTHERN SLOPE OF YIHEZHUANG SALIENT

Close to Chexi, Dawangbei, Guojuzi and Sikou hydrocarbon-generation subsag, the northern slope of Yihezhuang salient has favorable conditions to form oil-gas pools. Affected by multiphase tectonic activity, the structural feature of the northern slope of Yihezhuang salient is very complicated. For many oil-bearing series, the complicated and diversified traps and reservoirs and the widely distributed hydrocarbon reservoirs, the northern slope of Yihezhuang salient is a typical multiple petroleum accumulation zone having enormous exploration potential. The pool-forming conditions, the hydrocarbon reservoir types and distribution rule of the northern slope of Yihezhuang Salient are systematically analyzed in this paper, and it is pointed out that the buried-hill, stratigraphic onlap and unconformable hydrocarbon reservoirs would be the major exploration directions of the district in the future.
