【摘要】 南堡凹陷具有多凸、多凹、多物源、多旋回、多断裂的特点,具备了良好的地层-岩性圈闭发育条件。针对地震、地质问题和岩性油气藏的特点,确定了处理解释一体化的研究思路。通过砂岩体的攻关处理,砂体外形及内部反射结构更加清晰,在层序地层学研究的基础上,明确了研究层系;通过构造背景、沉积体系及古地貌等方面的综合研究,确定了岩性体发育区带及类型;根据地震反射特征及地震反演结果、地震属性分析等,精细刻画岩性体形态和平面分布特征;最后通过储层及物性预测、地质综合评价,优选出有利钻探目标,钻探后取得了良好的地质效果和经济效益。更多还原

【Abstract】 Nanpu Sag was a hydrocarbon-enriched depression with characteristics of multi-saliencies,multi-sags,multi-provenances,multi-cycles and multi-faults.It had good conditions for the development of stratigraphic-lithologic traps.The idea of integration of seismic dates processing and interpretation was determined in view of the characteristics of seismic,geological and lithologic hydrocarbon reservoirs.Based on the researching and processing of sandbody,the external shape of sandbody and internal reflection texture are more clear.Based on the study of sequence stratigraphy,series of strata for exploration is determined.The favorable zones and types of sand body are defined by comprehensive geological analysis.According to the seismic reflection features and seismic method,the fine characterization of sandbody shape and its plain distribution are determined.Finally,by reservoir prediction and comprehensive geological evaluation,the favorable target is optimized for well drilling.The remarkable exploration effect and the economic benefit are obtained after well drilling.更多还原
