归一化总梯度法在松南油气藏检测中的应用

Normalized total gradient method as replied to the detection of Songnan hydrocarbon reservoir

归一化总梯度是重磁异常解释中常用的一种反演方法，本文将重力归一化总梯度法应用于松南油气藏的检测，并结合重磁异常剖面和松南地区地质、地球物理条件，分析了归一化总梯度法在这一地区应用效果明显的原因。

The normalized total gradient method is one of the inversion methods in the interpretation of gravity and magnetic anomalies. The paper presents the use of the method in detecting the Songnan reservoir. By integrating the gravity and magnetic anomaly profile and geologicgeophysical situations in Songnan Arca,the author analyzes the reason why the method can bring evident results.
