宽线技术在下扬子地区页岩气勘探中的应用
Keywords: 宽线地震,地震数据采集,页岩气藏,信噪比,大组合,下扬子地区
Abstract:
？下扬子地区广泛分布的泥页岩有机碳含量高，是页岩气勘探的有利区域。但该区构造复杂，地层褶皱发育，地震资料信噪比低，成像质量差，造成页岩气勘探、开发难度大。基于对工区现有资料的分析，通过正演模拟对采集参数进行精细论证，设计出宽线（3线2炮，60m炮距）大组合（crossline方向）地震数据采集方法，所采集资料信噪比大幅提高，有效反射的波组特征明显，构造清晰，剖面品质提高。模型正演和实际应用都证明该方法是下扬子构造变形区提高地震资料信噪比、改善成像效果的适用技术。
