摘　　要：通过研究构造演化和生烃与油气运聚散的关系，总结成功的地震相和基准面旋回高分辨率层序地层学方法在寻找岩性地层油气藏中的应用，分析了各种特殊地震处理和油气检测方法的适用性和可靠性，提出了３个层次、５类方法的非构造油气藏勘探思路。３个层次及有关方法是：在盆地规模上进行整体、动态、综合研究，寻找有利油气聚集带；在有利油气聚集带规模上，开展高分辨率层序地震地层学研究，寻找各类有效尖灭体和圈闭；在可能的圈闭基础上，利用地震烃类检测和化探技术进行圈闭评价。３个层次５类方法的全面研究和有机结合是减小非构造油气藏勘探风险，提高勘探成功率的有效途径。Three orders and five methods of non structural trap exploration are suggested based on the integrative research on the hydrocarbon generation, paleostructural evolution, seismic sequence stratigraphy, seismic and chemical hydrocarbon detection. Three orders and involved methods are:(1) to find out favorable exploration area and interval through the basinwide dynamic and integrative analyses of paleostructure, hydrocarbon generating history, area and intensity;(2) to search for large scale of sandbody updip wedge out traps on the promising area by means of seismic sequence strtigraphy;(3) to assess whether the traps contain oil or gas using effective methods of hydrocarbon indication. Comprehensive study and organic combination of three orders and five methods will be an effective way to degrade risk and enhance success ratio for oil and gas exploration.
