【摘要】 目的对济阳拗陷阳信洼陷油气富集的主控因素进行研究。方法研究阳信洼陷油气成藏条件、油气富集规律。结果阳信洼陷纵向上成熟油气主要富集于沙四上、沙三层段,沙三段产低熟油,沙一段富集生物气,平面上油气主要富集于中部正向构造带,油气环绕次洼生烃中心呈环带状分布。结论控制阳信洼陷油气富集的主要因素有油源条件、构造特征、火山活动以及生储盖组合与构造的配置等;区域构造背景控制了油气运移的指向,油气源条件制约着油气的富集程度,生储盖组合与构造特征的配置,是造成不同构造部位主要储油气层位和油气藏类型差异性的直接原因。更多还原

【Abstract】 Aim Studied main controlling factors of hydrocarbon accumulation in Yangxin Subsag of Jiyang Depression.Methods Studied the formation conditions of hydrocarbon reservoir,distribution of hydrocarbon accumulation.Results There are many petroliferous zones vertically,and maturated oil-gas were generated mainly in upper Es4 and Es3,and low-matured oil-gas were produced mainly in Es3,and biogenic gas were formed to Esl.Oil-gas were concentrated in central positive structural zones in plane,and were encircled to producing hydrocarbon focus of inferior subsag according to circularity.Conclusion The major factors controlling hydrocarbon accumulation include oil-source conditions,structural features,volcanic activities and the collacation of source rock-reservoir-caprock assemblages to structures.Territorial tectonic background controls hydrocarbon migration direction,and oilsource conditions constraints hydrocarbon enrichment,and the collocation of source rock-reservoir-caprock assemblages to structures is the direct reason to result in the differences of major hydrocarbon-bearing horizons and hydrocarbon reservoir types in different tectonic position.更多还原
