多种信息复合在含油区深部构造研究中的应用

Remote Sensing, Geological and Geophysical Data in Connection with the Study of Deep Structure of Petroliferous Platform Region

研究区位于四川盆地的东北部,是一个油气的重要勘探区。为了进一步缩小勘探靶区,在10万平方公里的范围内采用了卫星遥感影像与区域地球物理资料(航磁,重力)的复合研究,同时与区域地质资料进行综合分析,发现了一些与油气田分析密切相关的长期活动的隐伏断层以及一系列的环形构造,为进一步油气勘探,提供了一批远景地区。

Research district is located in the Northeastern part of Sichuan province, west of China. In order to select the target of petroleum exploration, images of landsat were superimposed regional geophysical data (aeromagnetic, gravity) and were analyzed connecting with regional geological data. As a result, some subtle-inherited fault zones and a series ring-shape structures are discovered. These structures are closely related to the existed petroleum structure, and provided some prospect regions for oil and gas exploration in the future.
