利用美国陆地卫星（Ｌａｎｄｓａｔ－２）图像资料，结合区内地质、重磁力等资料，对胶莱盆地及周边地区的卫星影像进行构造地质解译，得到规模不同的线性构造２００余条。经分析认为，它们主要反映本区的断裂构造特征，按延伸方向将区内线性构造划分为北西、北东、东西、北北东、北东东及近南北向共六组。其中以北西、北东及近东西向的断裂构造最为发育，它们构成了盆地断块构造的基本格局。在盆内组合处理图像上还识别出环形构造２６个，结合重力资料探索了其地质属性，研究认为，胶县断裂以南地区为最有利油气勘探区．
Based on the Landsat-2 image data of the United States and the geological and gravity-magnetic relics in the area, more than 200 linear structures with different scales were obtained by structural and geological interpretation of the satellite images in the Jiaolai Basin and surrounding areas. According to the analysis, they mainly reflect the structural features of faults in this area, and divide the linear structures in the area into Northwest, North East, East-West, North-East, North-East and Near North-South directions according to the extension direction. Among them, the fault structures in the northwest, northeast and near east-west are the most developed, and they constitute the basic pattern of fault block structure in the basin. Twenty-six ring structures were also identified on the combined basin images, and their geological properties were explored in combination with gravity data. It is believed that the area south of the Jiaonan fault is the most favorable oil and gas exploration area.
