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。
In view of the complex geological conditions of oil and gas, the poor seismic data quality, low signal-to-noise ratio, prominent static correction problem, large imaging difficulty and low accuracy of the constructed map in the southern margin of Junggar Basin, the research ideas, methods and processes , A number of key technologies such as static correction, pre-stack depth migration imaging, structural modeling and variable speed mapping are adopted to collect, process and interpret the key structural targets (Horgos anticlines) in the southern margin It is of great significance to guide the exploration of oil and gas in the southern margin of Junggar Basin by tackling a series of structural traps with drilling values and providing well position recommendations.
