根据地矿部航空物探遥感中心、胜利石油管理局的研究结果，胜利油田某区的磁性层可分为浅、中、深三层。本文采用了多次插位切割法对该区的航磁异常进行了划分。具体作法是：①首先采用4次插值切割法，计算出区域异常，然后用磁异常减去区域异常得到局都异常，这就是浅部异常。经过化极垂向一次导数和垂向二次导数的验证，吻合很好，说明浅部异常的可信度高。②将新的区域异常继续进行6次插值切割法，再次计算区域异常和局部异常，将此局部异常作为中部异常，区域异常作为深都异常。在浅、中、深部异常划分的基础上，作者进行了细致的解释工作，包括：①确定了第四系地层中的9处玄武岩、凝灰岩或干扰磁性源的分布范围、顶深和磁化率；②确定了沙三段地层中的玄武岩体的合理分布范围、顶深和磁化率，并得到区内两口钻井资料的证实；③推断了一条基底断层。
According to the research results of Aerogeophysical Remote Sensing Center and Shengli Petroleum Administration of the Ministry of Mines and Maglevs, the magnetic layer in a certain area of Shengli Oilfield can be divided into shallow, middle and deep layers. In this paper, a number of interpolation cutting method for aeromagnetic anomalies in the region were divided. The specific approach is: ① first by 4 interpolation cutting method to calculate the regional anomaly, and then subtract the regional anomaly with magnetic anomalies are unusual, this is the shallow anomaly. After the normalization of the primary vertical derivative and vertical second derivative verification, good agreement, indicating the credibility of shallow anomalies high. ② The new regional anomalies continue interpolation interpolation method 6, once again calculate the regional anomalies and local anomalies, the local anomalies as the central anomaly, the regional anomalies as a deep anomaly. On the basis of the shallow, middle and deep anomaly division, the author carried out detailed explanation work, including: ①Determining the distribution range, top depth and magnetic susceptibility of 9 basalts, tuffs or interfering magnetic sources in Quaternary strata; ② Determine the reasonable distribution range, top depth and magnetic susceptibility of basalt body in the third member of Shahejie formation, and confirm the drilling data of two wells in the area; ③ Inferred a basement fault.
