随着勘探开发的深入,塔河油田主产油区的原有地震资料已不能满足油田开发精度的需求,针对这一问题,在艾协克和桑塔木三维工区,开展了高精度地震勘探方法的研究。首先,针对工区的地震地质条件和碳酸盐岩储层特征,基于前期的勘探成果,利用工区丰富的地震地质资料,分析存在的问题;然后,结合工区的地震地质条件,在正演模拟分析的基础上,通过对缝洞体地震波场的认识,提出下一步高精度地震勘探的方法技术。

The original seismic data ot major oil province at the Tahe oilfield cannot meet the needs of high precision seismic technology. The paper aimed to seismic-geologic condition and carbonate reservoir characteristic in the ixieke-sangtamu block, to high precision seismic exploration is discussed. Based on exploration production, the existed problems are analyzed using plenty of seismo-geologic data in the target area. By the known the seam-cavern body seismic wave field, forward modeling, illumination, presents the next the technology on high precision seismic exploration.
