成油体系与成藏动力学研究的层次分析

Hierarchy Analysis of Petroleum System and Dynamics of Reservoir Formation

层次分析是在不同尺度上、采用不同的研究手段对客体所包含的多种对象及其作用过程进行描述、解释和建模的研究方法。成油体系与成藏动力学研究需要将研究对象分为成藏空间、油气物质量、盆地流体能量、地质过程时间等4个方面进行层次分析。本文详细说明了不同层次规模上4个研究对象包含的描述内容、解释方法和分析建模等诸方面的不同之处。在层次分析的基础上,进行层次归一综合评价,使成油体系与成藏动力学研究更具可操作性、准确性、使用性和定量化。

Hierarchy analysis is a methodology of description, interpretation and modeling to geological bodies of various sizes and their acting process. Hierarchy analysis of petroleum system and dynamics of reservoir formaotion include 4 key aspects, i.e., reservoir forming spaces, oil & gas amount, basin fluid energy and processing time. This paper discusses in detail the differences of description, interpretation and modeling of hierarchy in different scale. Finally, based on the various analysis of hierarchy, hierarchy combination can make the studying of petroleum system and dynamics of reservoir formation easier, more accurate and more quantitative in petroleum exploration.
