摘　　要：针对准噶尔盆地南缘油气地质条件复杂,地震资料品质非常差,信噪比低、静校正问题突出、成像难度大、构造成图精度低等难题,提出了山前复杂构造研究思路、方法和流程,采用了静校正、叠前时间深度偏移成像、构造建模、变速成图等多项关键技术,对南缘重点构造目标(霍尔果斯背斜)进行采集、处理、解释一体化技术攻关,落实了一批有钻探价值的构造圈闭并提供了井位建议,对指导准噶尔盆地南缘油气勘探工作具有重要意义。Although the oil-gas resources of southern margin of Junggar Basin are very abundant,geologic condition is so complicated that the quality of seismic data is very bad,signal-to-noise ratio is low,static correction problem is apparent,the difficulty of imaging is big and the precision of structure mapping is poor.For resolving these four big problems,the idea,method and flow on sophisticated structure study in piedmont are put forward in this article.Omnibus key technique is adopted,tackling key problem carried out by integrative study mode of acquisition,emphatic structure target of southern margin(Horgos anticline) processed and interpreted,a set of structure traps which have the value of drilling and offering well site disposition is fulfilled.
