| 摘 要： | 由于受多种因素的影响,北黄海盆地地震反射资料品质较差,信噪比较低,浅层多次波尤其是短周期多次波极为发育,中深层反射波组特征不明显,浅层出现强反射屏蔽现象,为此,采取重、磁、震三方面资料相结合的地球物理综合解释方法尤其必要。通过分析地球物理场特征,在对照分析重、磁、震平面和剖面资料的基础上,选取重点剖面线进行重、震联合反演并进行综合解释,提出了重磁解释结果与地震解释结果不吻合之处,为进一步研究北黄海盆地打下基础。

| Abstract: | Due to the interferences of several factors, the seismic data in the North Yellow Sea basin are characterized by poor quality, low signal-to-noise ratio and weak ineffective wave energy. In addition, multiple waves of the shallow layer are very strong, characteristics of reflection waves of the medium-deep layer are not clear, and the shallow layer has strong reflective screen. It is therefore necessary to adopt comprehensive interpretation which applies gravimetric and magnetic data in combination with seismic data. Based on analyzing features of the geophysical field and comparing seismic, gravimetric and magnetic data in plane and section, the authors selected key section lines to conduct joint inversion of seismic and gravimetric data and perform comprehensive integrated interpretation. The inconsistency between the interpretative result of gravity and magnetic data and that of seismic data is pointed out. All the achievements made have laid a foundation for further study in the North Yellow Sea basin. |
