| 摘 要： | 在油气勘探中,与油气相关的磁异常由于其信号非常弱,通常很难从干扰中分离出来,可以证明希尔伯特变换滤波方法增强弱磁异常是一种有效方法,广东三水盆地的剖面处理解释说明了这一点。

| Abstract: | In oil and gas prospecting,the signals of gravity and magnetic field is always very weak,so we can not distinguish them from the noise very easy.So how to get the real anomaly from the target geological object become the key Hilbert transforming filter is an efficient method to get the useful anomaly.Using this method,we have processed the gravity and magnetic field data from Sanshui area in Guangdong Province. |
