| 摘 要： | 南海火成岩油气藏具有广阔的勘探前景,综合利用地球物理方法圈划与识别火成岩体、研究火成岩分布是火成岩油气藏研究的基础。针对南海重磁场特征,采用低纬度、变倾角化极技术进行了磁异常化极处理,利用优选延拓方法实现重磁异常分离并提取南海海域浅部火成岩重磁异常信息,利用磁异常三维相关成像给出南海火成岩的三维空间等效分布,在重磁梯度突出局部异常边界信息的基础上,通过梯度加权的重磁相关分析勾画不同类型火成岩的平面展布,火成岩的分布特征显示出受地壳深部结构及断裂构造的控制与影响。

| Abstract: | Igneous rocks in the South China Sea have broad prospects for oil and gas exploration.Integrated geophysical methods are important approaches to study the distribution of igneous rocks and to determine and identify igneous rock bodies.Aimed at the characteristics of gravity and magnetic fields in the South China Sea,several potential field processing methods are preferentially selected.Reduction to the pole by variable inclinations in the area of low magnetic latitudes is used to perform reduction processin... |
