吐哈盆地玉果-雁木西复式油气聚集带成藏特点

通过对玉果—雁木西区带油气成藏特点的分析，认为该区控油气构造主要形成期为燕山运动中晚期；下侏罗统至第三系共发育有五套有效的储盖组合，含油气层系多且油藏类型丰富；区带油气运移以侧向为主，具有晚期成藏特点；如何在该区把握油气运移路径，并在有利方向上精细落实勘探目标，是该区带的取得成功的关键。

Formation Reservoir Characteristics of Complex Hydrocarbon Accumulation Zones in Yuguo-Yanmuxi Area of Turpan-Hami Basin

From analysis of reservoir characters in Yuguo-Yanmuxi Petroliferous area, the middle-late Yanshan movement episode is considered to be primary stage of controlling the hydrocarbons by structures. There are five sets of effective reservoir-cap rock assemblages developed in Lower Jurassic to Tertiary, where many hydrocarbon-bearing sequences and reservoir types are found, and dominated by lateral hydmearbon migration. It reflects the characters of late-stage formation reservoirs. Hence, to grasp the way of the hydrocarbon migraion in order to detailed determine the prospecting targets in favorable directions could be as principle train of thought for further exploration of this area in future.
