摘　　要：应用多学科、多指标勘探数据和图形资料评价一个盆地或探区内的多个目标,优选有利含油气远景靶区,传统方法多是定性评估。以新疆柴窝堡凹陷为例,利用地震构造、化探、遥感、放射性γ能谱、土壤微磁等多学科、多指标资料,以局部构造、构造部位、烃微渗漏综合异常及油气属性等地质要素,采用模糊综合评判方法对多个目标进行量化评价,优选了其中较有利靶区。Most of the traditional methods are qualitative assessments in optimized selection of the oil-gas poten-tial exploration targets within one basin or exploration zone by applying the multidisciplinary and multi-index prospecting data and graphics. This paper, makes a case study on the Chaiwopu Sag in Xinjiang, by means of fuzzy comprehensive evaluation, utilizing multidisciplinary resources based on seismotectonics, geochemical exploration, remote sense, radioactive γ energy spectrum, soil micromagnetics, meanwhile, integrating local structure, structure position, hydrocarbon microleakage composite anomalies, oil-gas properties information and other geological essential factors, to carry out quantitative assessment on the multi-target areas, from which some of significant targets are selected as the prospecting prospects.
