摘　　要：在综合分析吐哈盆地胜北洼陷石油地质特征、岩性油气藏成藏地质条件、成藏主控因素的基础上,认为吐哈盆地胜北洼陷主要发育3种类型的岩性油气藏,即斜坡带前缘砂上超型油气藏、前缘砂顶超型油气藏和前缘砂后期掀斜型油气藏,其中斜坡带前缘砂上超型岩性油气藏主要发育于胜北洼陷南缘古斜坡带,前缘砂顶超型岩性油气藏主要发育于胜北构造南斜坡,前缘砂后期掀斜型岩性油气藏主要发育于胜北洼陷西缘葡北构造东斜坡。Based on the studies of geologic features and conditions of lithologic hydrocarbon reservoirs, and on the analysis of their major controlling factors, we conclude that there are three types of lithological hydrocarbon reservoirs in Shengbei subsag： slope belt frontal sandrock onlap type, delta frontal sandstone anaphase tilted type, and delta frontal sandstone offlap type. Three favorable exploration directions are predicted, which are the north slope of the Huoyanshan structure, the south slope of the Shengbei structure, and the east slope of the Pubei structure.
