| 摘 要： | 以往关于油气运移路径的认识, 多是基于微观尺度上的物理模拟实验, 或是利用计算机模拟进行的, 而对油气运聚单元尺度的油气运移路径的确定研究还相对较少.以东濮凹陷濮卫地区为例, 从砂体和断层要素研究出发, 分析油气的优势运移通道, 结合生烃灶和油气的分布, 对优势运移通道的有效性进行评价, 进一步结合含氮化合物指标, 识别实际发生油气运移的路径.研究表明, 构造脊分析与地球化学指标追踪相结合可以较准确地识别油气运移路径, 砂体顶面构造脊和断层断面脊是油气运移的优势通道, 其能否成为运移路径, 以及作为运移路径运载量的多少则取决于生烃灶总烃量.濮卫地区油气沿断面脊纵向运移为主, 洼陷内部和濮城构造东翼斜坡带沿砂体顶面构造脊的横向运移次之, 含氮化合物指标分析表明该区大多数构造脊均为实际的油气运移路径.

| Abstract: | The former understanding about actual hydrocarbon migration paths is mainly based on the micro-scale physical simulation or the computer simulation,and the actual oil and gas migration paths only rely on indirect evidence.This paper takes Puwei area of Dongpu depression as an example,firstly we find out the dominated migration pathways of main sandbodies and faults,then analyze their relationships with hydrocarbon kitchens and reservoirs to evaluate their effectiveness,and lastly identify the paths of hydro... |
