摘要
从油气藏圈闭的形成与保存、油气藏成藏时间与期次、油气运聚特征和油气藏成藏模式四个方面总结了焉者盆地宝浪、本市图两油田的成藏特征。油气藏圈闭为古构造基底隆起背景上的披覆背斜或鼻状构造，后经改造，呈现今的断背斜或断鼻形态。宝中区块主要成藏期为侏罗纪末，宝北区块和本布图油田主要成藏期为晚第三纪。
The reservoir- forming characteristics in Baolang and Benbutu oilfields in tile Yanqi basin are studied in aspects of the formation and preservation of traps, the time of reservoir- forming, the features of oil and gas migration and accumulation and reservoir - forming patterns.
