| 摘 要： | 层次分析是一种将难于定量化的复杂问题,逐层分解为一系列可定量化的简单问题,进而进行求解的数学方法。将层次分析法用于油气资源定量评价具有较重要的意义。在楚雄盆地定性石油地质研究的基础上,采用层次分析法,选择生烃条件、储集条件、保存条件、圈闭条件、运移条件、油气微渗漏等专题信息,对楚雄盆地有利油气勘探区带进行了评价,认为楚雄盆地最有利的勘探区是牟定断弯背斜带及黑井凹陷超覆带之间的交际地带;片角凹陷;会基关穹窿背斜带。而有利储集带,长期发育的低势区,良好的圈闭条件是此区成藏最有利的控制因素。

| Abstract: | Hierarchical analysis is a mathematical method.It can gradually decompose a complicated issue which is hard to be quantified into a series of quantifiable simple issues,and then to be solved.This method has a feasible significance for quantitative evaluation of hydrocarbon resources.Based on the qualitative study of oil geology in Chuxiong basin and adopting the hierarchical analysis,we selected special information such as hydrocarbon conditions,reservoir conditions,preservation conditions,trap conditions,migration conditions,oil-gas micro-leakage conditions etc.and evaluated the favorable exploration zone.It is regarded that the borderland between the Mouding fault-bend anticlinal zone and the Heijing sag nappe area,the Pianjiao sag and the Huijiguan domal anticlinal zone are optimum exploration areas in Chuxiong basin.The profitable reservoirs,long-term developed low fluid potential localities and excellent trap conditions are the most favorable controlling factors for hydrocarbon reservoirs in this area. |
