摘要: 应用油气成藏动力学原理和方法,研究了西峰油田的地质背景、油气成藏动力学条件和成藏过程,探讨了油气成藏动力学机制.从纵向上划分出自源高压封闭、混源低压半封闭和他源常压开放3个油气成藏动力学系统.自源高压封闭系统中浊积砂层系和混源低压半封闭系统中近源岩的三角洲前缘砂层系,是今后进一步勘探的主要目标层系.

Abstract: The pool-forming dynamic conditions and process of Xifeng Oilfield in Ordos Basin were studied,and the pool-forming dynamic mechanism was discussed according to the pool-forming dynamic principle.The studied region was vertically divided into three pool-forming dynamic systems including self-sourced and high-pressure sealed dynamic system,mix-sourced and low-pressure half-sealed dynamic system,outward-sourced and normal-pressure opened system.The further exploration should be focused on the turbidity sandstone layer in the self-sourced and high-pressure sealed dynamic systems,and the delta-front sandstone layer near source rocks in the mix-sourced and low-pressure half-sealed dynamic systems.

Key words: pool-forming dynamics, hydrocarbon migration, hydrocarbon accumulation, delta-front sandstone, Xifeng Oilfield, Ordos Basin
