中东阿曼超级盆地形成背景、油气有序分布及主控因素
Formation Background, Orderly Distribution of Hydrocarbon, and Controlling Factors of Oman Super Basin in the Middle East
基于阿曼盆地油气勘探实践成果和商业油气田数据库,以含油气系统和成藏组合为单元,对其超级盆地的形成背景和油气分布规律开展分析.研究表明,阿曼盆地自前寒武纪以来经历了多旋回构造运动,但以克拉通边缘和被动陆缘为主要发育特征;总体以浅海边缘沉积为主,持续的海侵‒海退形成了优势的碳酸盐岩+膏盐/页岩岩相组合;各成藏要素高效配置,形成了5套含油气系统,垂向上叠置但互不干扰.盆地内油气分布呈现规律有序性:平面上环盐盆和隆起带分布,北部富油气、南部富油;纵向上围绕3套主力成藏组合分布,下部富油气、上部富油;富含常规油气、页岩油气和氦气,具有多层系、多类型资源立体成藏特征.分析认为阿曼盆地油气成藏与富集的主控因素有: 3大主力烃源灶是油气富集和有序分布的物质基础;盐盆内厚层盐岩和区域稳定发育的页岩控制了油气纵向有序富集;多期次断裂系统和区域不整合面为烃类/非烃类立体输导和有利圈闭形成提供重要支撑.
Based on the results of oil and gas exploration practices and the commercial oil and gas field database in the Oman Basin, this study analyzes the formation background and hydrocarbon distribution patterns in the super basin using petroleum systems and plays as units. Research indicates that the Oman Basin has undergone multi-cycle tectonic movements since the Precambrian, but is primarily characterized by the development of a cratonic margin and a passive continental margin. The deposition was predominantly in shallow marine marginal environments, where continuous transgressive-regressive cycles formed dominant lithofacies associations of carbonate rocks+evaporite/mudstone. The efficient configuration of various petroleum system elements has resulted in five petroleum systems that are vertically stacked but do not interfere with each other. The distribution of oil and gas in the basin exhibits a regular and orderly pattern: spatially, it is distributed around salt basins and uplift zones, with the north being rich in both oil and gas, and the south being rich in oil; vertically, it is distributed around three major plays, with the lower sections rich in both oil and gas, and the upper sections rich in oil. The basin is rich in conventional oil and gas, shale oil and gas and helium, characterized by a three-dimensional accumulation of multi-layer and multi-type resources. The analysis concludes that the main controlling factors for hydrocarbon enrichment in the Oman Basin are: three major source kitchens serve as the material basis for hydrocarbon enrichment and orderly distribution; thick salt rocks within the salt basins and regionally stable mudstones control the vertical orderly enrichment of hydrocarbons; multi-phase fault systems and regional unconformities provide critical support for the three-dimensional migration of hydrocarbons/non-hydrocarbons and the formation of favorable traps.
