【摘要】 海洋石油天然气勘探面临最大的困难是高成本、高风险、高技术,因此,对地球物理工作者及地球物理技术提出了更高的要求。在对前期钻井资料分析了解的基础上,通过对工区内地震资料进行分析研究,同时对火山岩的基本地球物理响应特征进行分析归类,识别并归纳出该工区内四种类型的火山发育模式,建立起工区内四种火山岩发育类型的地震响应特征规律。这一规律将有助于研究南中国海深水区地震反射异常区的分析论证,有助于揭示不同时期地震异常体性质,为该地区的石油天然气勘探工作提供更为准确的资料。更多还原

【Abstract】 One of the greatest difficulty in offshore oil and gas exploration is the high cost,high-risk,high technology,therefore,higher requirements is put forward for geophysical workers and geophysical techniques.In this paper,through preliminary analysis of drilling data on the basis of understanding and the work zone analysis of seismic data,geophysical response of the basic characteristics of volcanic rocks were analyzed and classified,and it is also summarized and established that identifying four types of volcanic development model the work area and the four types of seismic responses law in qigong volcanic area development.This law will help to study the South China Sea deep water seismic anomalies in the analysis and demonstration,to reveal the nature of different periods of anomalous seismic,and to explore oil and gas exploration in the region with providing more accurate information.更多还原
