【摘要】 以地质模型为基础,针对典型的潜山断裂带模式和主要勘探难点,利用正演模拟技术进行了地震波射线路径、CRP分析以及单炮模拟等研究,找出目标成像区,保证构造关键部位达到足够的覆盖次数,使地震资料准确成像。在室内对地震采集参数论证是否得当、观测系统的综合性能是否科学合理进行了探讨,从而提高了地震勘探解决复杂地质问题的能力。车古201和埕北30潜山的应用实例表明,该方法对今后高精度地震采集参数论证具有指导作用。更多还原

【Abstract】 Aimed at the typical patterns of buried-hill fractured zone and its main exploration difficulties, ray paths of seismic waves were calculated by forward modeling, CRP analysis and single shot simulation were implemented on buried-hill geology model to find out the imaging targets and ensure adequate coverage for key tectonic positions. The validity of acquisition parameters and the behavior of layout were studied by data processing techniques. The effectiveness of the above method was confirmed by the case study in Chegu 201 and Chengbei 30 buried hill reservoir.更多还原
