【摘要】 由于受多种因素的影响,南海东北部海域中深部地震反射资料品质较差,信噪比较低,有效波能量弱,中深层反射波组特征不明显,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,通过对研究区周边岩石物性特征分析、重磁资料精细处理与分析,结合地震资料显示的地层结构分析,圈出该地区的中生界分布范围,为我国油气资源战略选区和勘探开发提供地质科学依据。更多还原

【Abstract】 Owing to interferences of several factors,the deep seismic data obtained from northeastern South China Sea basin are poor in quality,low in signal-to-noise ratio and weak in effective wave energy.In addition,the characteristics of reflection waves of the medium-deep layer are not clear.In view of such a situation,the method of comprehensive interpretation that applies gravimetric and magnetic data in combination with seismic data is adopted in this paper.By analyzing the features of peripheral rocks in the study area and further processing and analyzing the gravimetric and magnetic data in combination with the stratigraphic analysis,the authors found the distribution of Mesozoic strata,thus providing a scientific basis for oil and gas exploration.更多还原
