摘要
应用陆相层序地层概念模型 ,研究柴达木第三纪盆地层序格架中油气分布规律 ,探讨各层序中不同体系域中沉积体系的配置关系、生储盖组合、油气聚集模式、圈闭类型及分布。认为第 构造层序中的最大湖泛体系域最具生油潜力 ;高位湖退体系域为最有利的储集层 ;上超体系域成藏类型丰富 ,具有较好的勘探前景。初步总结出陆相层序中自生自储、下生上储、侧向运移、垂向运移四种油气运移聚集模式。
The oil distribution rule of oil and gas in the Tertiary basin of Chaidamu was studied by using the model of the terrigenous sequence.The arrangement relation of the sedimentary system in different system of the sequence and the source reservior cap combination and the distribution of trap type were discussed.It was considered that the Lake Flowage System Tract pocessed better potential for oil formation,the Lake Regressive System Tract was the most favourable reservior horizon and the Onlap System Tract had abundant reservior types and better exploration pospects.Four kinds of models of the oil migration and accumulation were proposed and summarized.
