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。
By studying the relationship between tectonic evolution, hydrocarbon generation and hydrocarbon migration and accumulation, the paper summarizes the successful application of high resolution sequence stratigraphy of seismic facies and reference plane cycles in the search for lithologic stratigraphic reservoirs, analyzes various special seismic treatments And the suitability and reliability of oil and gas detection methods, three-level and five-type methods for exploration of non-structural reservoirs are proposed. Three levels and related methods are: to conduct a holistic, dynamic and comprehensive study on the scale of the basin in search of beneficial oil and gas accumulation zones; to conduct high-resolution sequence stratigraphic studies on favorable oil and gas concentration zones and to find out various effective points Extinct bodies and traps; based on the possible traps, traps were evaluated by seismic hydrocarbon detection and geochemical exploration techniques. The comprehensive study and organic combination of three levels and five kinds of methods are effective ways to reduce the risk of exploration for non-structural reservoirs and improve the success rate of exploration.
