| 摘 要： | 柴达木盆地北缘赛什腾山前带逆掩推覆构造发育,地表条件差,地震勘探困难,为此在该区开展了连续电磁剖面法勘探研究。采用Robust、远参考、静态校正多种预处理方法有效压制了干扰,提高了数据品质。通过综合应用Bostick、CMI和二维连续介质反演方法突出了有效异常,清晰地揭示了赛什腾山前带逆掩推覆构造的发育特征,明确了山前逆掩推覆断裂下盘地层空间展布及该区的盆山接触关系。

| Abstract: | In the piedmont zone of the Saishiteng Mountain on the northern margin of Qaidam Basin,the thrust-nappe structure is developed,the surface condition is poor and hence the seismic prospecting is difficult.As CEMP method is hardly affected by the shielding effect of overthrust nappe structure and the effect of surface condition,the authors conducted researches on CEMP exploration in this area.In this paper,several methods such as Robust,remote reference technique and static correction were adopted in data pre... |
