为了充分发挥航磁测量在开展第二代石油普查中的作用，我们于1982年用高精度光泵磁力仪在松辽中央坳陷区作了1：20万高精度航磁测量，获得了大量地质信息：1．发现了147个局部小异常，测出了磁场的微弱变化和细节。经地震、钻井等资料综合分析，认为它们都反映空间不同的地质构造。2．测出了一系列沉积盖层中的磁性层，并圈出了其中的局部构造。3．圈定出了隆起区或者是隆起带上的次一级构造、坳陷区中的沉积中心和鞍部构造，深入划出“坳中之凹”。4．准确地定出了一批中、小型断裂的位置。5．根据磁测结果，预测出含油气远景区及确定出对成矿有利的局部构造。
In order to give full play to the role of aeromagnetic survey in carrying out the second-generation oil census, we made a 1: 200000 high-precision aeromagnetic survey in 1982 with a high-precision optical pumping magnetometer in the central Songliao depression, obtaining a large number of Geological information: 1. A total of 147 local small anomalies were detected and the weak changes and details of the magnetic field were measured. After a comprehensive analysis of the earthquakes and drilling data, they are all considered to reflect the different geological formations. 2. A series of magnetic layers in the sedimentary capstones were detected and some of them were excavated. 3. Delineated the uplift or uplift belt sub-level structure, the depression area of the sedimentary center and the saddle structure, in-depth draw “depression Au”. 4. Accurately set a group of small and medium-sized fracture location. 5. According to the results of the magnetic measurements, the petroleum-bearing prospect is predicted and the local structure beneficial to metallogenesis is determined.
