1970年以来,在进行构造航磁测量时,我们发现了许多微弱的局部异常,这些异常往往与局部构造有着密切的关系,有些异常就是含油气局部构造的反映。进入80年代,随着仪器精度的提高和测量技术方法的改进,很多微弱的地磁场信息被测得。1982年我们在松辽盆地中部1:200000高精度航磁测量中圈出147个局部构造,其中有105个与地震圈定的构造相吻合。1985年在胜利油田1:50000大比例尺的构造航磁测量中,在近4000km~2面积中共圈出几
Since 1970, during the construction of aeromagnetic surveys, we have found many faint local anomalies, which are often closely related to the local structure. Some anomalies are the reflection of the local structure of petroleum-bearing gas. Into the 80’s, with the improvement of precision instruments and measurement techniques and methods to improve, a lot of weak geomagnetic field information is measured. In 1982, we circled 147 local structures in the 1: 200000 high-precision aeromagnetic survey in the central part of the Songliao Basin, of which 105 coincided with the structure of the seismic circle. 1985 Shengli Oilfield 1: 50000 large-scale structural aeromagnetic survey, in the nearly 4000km ~ 2 area of a total of several circles
