用层次分析法定量评价成藏系统——以四川盆地中西部为例

The Analytical Hierarchy Process to Quantitatively Evaluate Petroleum Reservoir Formation System—an example from the middle-western area in Sichuan basin.

油气成藏系统研究是在含油气系统研究基础上提出的对油气评价单元进一步细分的一种方法,也遵循系统原则,具有系统的规律,可作为油气评价的地质单元。层次分析法是系统工程的一个新的分支,符合系统的集合性、关联性、层次性、非简单加和性等特点,是将定性分析与定量分析相结合的一种决策方法。应用层次分析法,对四川盆地中部上三叠统进行定量评价,取得了较好的效果。

The petroleum reservoir formation system is an approach for further subdivision of petroleum evaluation units proposed based on petroleum system study.It adheres to the principle of petroleum system,and possesses the reg-ulations of the system.It can be as a geologic unit for petroleum evaluation.The analytical hierarchy process belongs to a new branch of the system study,and is in accordance with the properties of sets,correlation,hierarchy and non-simple addition.So it is also a decision-making approach of the qualitative integrated with quantitative analysis.By applying the analytical hierarchy process to quantitative evaluation of Upper Triassic in the middle area of Sichuan basin,good results are obtained.
