松辽盆地通过高精度航空磁测,取得了重要的地质成果:105个具有磁性界面的地震局部构造,航磁都有反映,而且还新发现了埋深为2.5—4.0km的较深的局部异常42个;查明了西斜坡并非单斜,拗陷中还有凹陷;确定了一批新的断裂。这些高精度航磁成果,扩大了该盆地寻找油气田的新领域,开创了航空磁测由研究区域构造为主转入研究沉积盖层构造和直接寻找油气田为主的新局面。
The Songliao Basin has achieved important geological results through high-precision aeromagnetic surveys: 105 local structures with magnetic interfaces, aeromagnetic reflection, and newly discovered deep localities with a depth of 2.5-4.0 km 42 anomalies; it is ascertained that the west slope is not monoclinic, there are also depressions in the depression, and a number of new faults have been identified. These high-precision aeromagnetic achievements expand the new field of oil and gas field exploration in this basin and open up a new situation in which the aviation magnetic survey is mainly conducted from the study area structure to the study of the sedimentary cover structure and the direct search for oil and gas fields.
