| 摘 要： | 珠江口盆地存在丰富的油气资源,勘探前景受到越来越多的关注。局部磁异常往往与含油气局部构造密切相关。通过对珠江口盆地大比例尺高精度航磁资料处理和分析,识别出5种航磁局部构造异常:基岩凸起局部构造异常、与基性侵入岩有关的局部构造异常、与中酸性侵入岩有关的局部构造异常、与火山岩有关的局部构造异常、与沉积层有关的局部构造异常。对各种局部构造异常进行了较细致的描述,并结合地震、重力、钻孔等资料对典型异常进行了地质解释,为油气勘探提供了依据。

| Abstract: | There are abundant hydrocarbon resources in the Zhujiang River mouth basin,whose hydrocarbon exploration potential has attracted more and more interest among scientists.Local magnetic anomaly is always bound up with local structural trap of hydrocarbon resources.Based on processing and analysis of large-scale and high-resolution aeromagnetic data,the authors distinguished five kinds of local aeromagnetic anomalies related to structural trap.They have to do with basement rocks,basic intrusive rocks,intermedi... |
