在三维地震资料解释的基础上利用时间厚度法，详细分析了吐哈盆地台北凹陷胜北构造带主要目的层三间房组在燕山中、晚期及喜马拉雅期的构造演化特征．认为胜北2号构造是燕山期古构造，且在喜马拉雅期继承性发育。在时间上，构造发育与胜北次四烃源岩（J1b-J2x）生排烃高峰匹配良好；在空间上，胜北2号构造长期位于生油凹陷北倾斜坡的高部位，是油气运移的优势方向．具备燕山期、喜马拉雅期两期成藏的有利条件，且后期保存好。胜北3号构造形成于喜马拉雅早期，具凹中隆的特点，其成藏期在喜马拉雅期。
Based on the interpretation of 3D seismic data, time-thickness method is used to analyze the tectonic evolution of the Sanfangfang Formation in the middle and late Himalayas and the Yanshanian main target formation in the Shengbei structural belt of the Turpan-Hami basin. It is concluded that the structure of Shengbei 2 is an ancient Yanshanian structure and inherited in the Himalayas. In terms of time, the tectonic development matched well with the hydrocarbon generation and expulsion of Jibei-Si source rock (J1b-J2x). In space, the structure of Shengbei 2 is long-term located in the high slope of the north slope of the oil- The direction of the move. With Yanshanian, Himalayan period of two favorable conditions for accumulation, and later preserved. Shengbei 3 structure formed in the early Himalayas, with a concave Long features, the accumulation period in the Himalayan period.
