牛圈湖-牛东地区三维地震资料精细目标处理
|
摘要
近年来,三塘湖盆地由于马朗凹陷的突破,储量进一步扩大,具有一定勘探潜力。针对工区地形较为复杂,静校正问题特别严重;前侏罗纪地震原始资料信噪比较低;地层变化较快,断层断点不清楚等问题,采用基于岩性的叠前高保真连片处理,多域循环的去噪方法,精细速度分析及高精度动、静校正技术,叠前时间偏移处理等技术,使牛圈湖-牛东地区三维地震资料处理取得了较为理想的效果。
With the breakthrough of Malang sag in recent years,the reserve in Shantanghu basin increased further with certain exploration potential.As for a series of problems such as complex terrain of work area,severe static correction,low signal-to-noise of original seismic data of pre-Jurassic,faster formation variation,unsharp fault and breakpoint and so on,the technologies of pre-stack high fidelity merging processing based on lithology,multi-domain noise suppression,fine velocity analysis,high precision dynamic and static correction and pre-stack time migration were applied.3-D seismic data processing of Niujuanhu-Niudong area has gained good effect.
